| A Management System for Visual Communication Design at Film Studio | | BIBAK | Full-Text | 13-21 | |
| Hong-Sheng Chen | |||
| This research aims to propose a design management system for helping
designer to make arrangement of the furniture in a film shooting studio. The
main issue is that furniture has its own characters, and it matches to other
furniture in different degree. Therefore, designer need help to calculate the
appropriateness. The appropriateness comes from items' color, texture and its
image to audience. This management system help designer to visualize the result
of combination by simulation. Keywords: visual design; film studio | |||

| Hironori Egi; Shotaro Houri; Yukari Kato; Tatsuya Terada; Wataru Tsukahara; Masaki Nakagawa | |||
| To improve lessons in accordance with students' comprehension levels,
evaluation of teaching performance has been carried out by questionnaire and
lesson study. However, lesson study in the context of faculty development is
difficult for participants to spend long time for classroom observation and
reflective discussion. Even if they have time for discussion, unfocused
discussion often causes less fruitful and mutual understanding. We are
developing an annotation tool not only to solve the above-mentioned time and
space constraint but provide benefits owing to archiving lessons and their
reviews. We design a pen-based annotation tool by which reviewers can write
comments and draw marks onto on-line and off-line movie of class observation.
The details of the annotation tool and user feedback from preliminary
experiment in actual classrooms are described in this paper. Keywords: Annotation; lecture video; faculty development; peer reviewing; pen-based

| Usability Analyses of CRM Systems in Call Centers: The Data Mining Approach | | BIBAK | Full-Text | 40-48 | |
| Ádám Horváth; László Laufer; András Kangyal | |||
| We carried out a usability research based on the methodology of Software
Usage Mining of the CRM system used in the Call Center of a major Hungarian
telecommunication company. This paper describes the specific usability aspects
of CRM systems used in Call Centers. By analyzing the communication model of
the customer-company interaction, we identify the key areas of usability and
data mining in the process. Our research has revealed how Web Usage Mining
provides invaluable insights for identifying usability issues on a quantitative
basis. Our results showed how a wizard-like interactional model would suit the
process of customer care better, than the currently applied menu driven
architecture. In the specific context of a Call Center, Web usage Mining is
proposed to used as an evaluation tool to provide fairer assessment for Call
Center operators. Keywords: usability; data mining; web usage mining; CRM; call center | |||
| Urgent Collaboration Service for Inclusive Use | | BIBAK | Full-Text | 49-58 | |
| Naotsune Hosono; Hiroyuki Miki; Michio Suzuki; Yukata Tomita | |||
| At the modern universal design society, this paper discusses the usefulness
of the urgent collaboration service that is originally proposed by deaf people.
They will be in trouble at such the occasion of disasters or accidents. At the
very first of the survey many deaf people are asked their difficulties. From
the point of context of use, it is best useful, effective and particularly
efficient at the deaf patient complaint of pain/ache/grief among the selected
ten items. Those requirements are drawn visually by pictograms or icons that
are easy to understand even such emergency situation. Proposed urgent
collaboration service placard is then evaluated by deaf people in the manner of
the usability test. The results with this placard are that the time to
communicate is shorter for about 30%. The placard is also used by foreign
people and is translated into English, Spanish, Korean and Chinese for them.
This placard can be also downloaded by specified URL in personal. It is also
being proposed to Japanese government to have the available both in the
ambulance and hospitals or public spaces. Keywords: collaboration service; inclusive use; human interface; usability;

| Improvement of Member's Concentration during Discussion | | BIBAK | Full-Text | 59-68 | |
| Junko Ichino; Kazuhiro Takeuchi; Hitoshi Isahara | |||
| We developed face-to-face single display groupware (SDG) that has a novel
circular frame and enhanced multiple pointers. The aim of the study is to
encourage groups to concentrate on their discussions and thereby improve their
cooperative decision-making. We analyzed the information input methods and
information that should be shared in a face-to-face SDG by surveying related
work. The interface was designed based on this analysis. Three experiments were
carried out, with a general parallel input system tested for comparison. The
results proved that group task accuracy, participants' memory, and their
subjective evaluation improved when our SDG was used. Keywords: face-to-face meeting support; concentration on discussion; single display

| Representation Method for Engineering Perspective | | BIBAK | Full-Text | 69-76 | |
| Gaku Ishii; Masatake Sakuma | |||
| For most Japanese Companies, knowledge succession is important for retaining
technical competitiveness in the context of the rapid change of human
resources. While efficient and effective knowledge succession requires the
support of an IT system, the requirements for the supporting system are severe.
That is, the system not only must offer the knowledge users need, but also must
represent how to apprehend and utilize the knowledge. This paper introduces a
method of representing technical knowledge considered in the development
process of a knowledge succession support system (IVYs). It focuses on the user
interface representing the standard or situation-dependent perspective of
technical knowledge that experts define. Keywords: KM (knowledge management); knowledge succession; engineering-support system;

| A Skill Transfer Method for Manual Machine Tool Operation Utilizing Cutting Sound | | BIBA | Full-Text | 77-86 | |
| Takashi Kawashimo; Noriaki Sato; Daisuke Doyo; Michiko Anse; Tsutomu Tabe | |||
| This study focuses on the inheritance of skills that has faced difficulties through the years in Japan. Sensorimotor knowledge, which is hard to be described by words alone, is often seen in technical skills in a manufacturing environment in Japan. Interpreting sensorimotor knowledge as formal knowledge, attempts have been made to impart technical skills but have faced barriers particularly in lathe processing due to no visual check of finished quality being allowed. Thus, this study suggested training on the inheritance of skills utilizing the level of cutting sound generated in process. Novice workers served as experimental subjects for an experiment to verify the effectiveness of proposed training. | |||
| A Business Performance Measurement Model for Mobile User Interface | | BIBAK | Full-Text | 87-93 | |
| Min-Jeong Kim; Jonghun Park | |||
| In this paper, we present a new framework for measuring business performance
of mobile user interfaces (UIs). Until now, the performance measurement of
mobile UI was mainly to assess usability performance. Yet, as mobile phones are
increasingly replacing wired devices, stakeholders in mobile phones began to
invest a lot of time and money to mobile UI development. As a result, it is
desirable that the business performance of mobile UI has to be measured
qualitatively as well as quantitatively. This paper develops a measurement
model for business performance of mobile UI based on BSC (Balanced Score Card).
The proposed model contains "Financial", "Customer", "Internal Business
Processes", and "Learning & Growth" perspectives. We applied the presented
measurement model in a real world mobile UI design project. Finally, we
demonstrate the benefit of applying the proposed model to quantitatively
measure the business performance. Keywords: User Interface; Mobile Phone; Business Performance; BSC (Balanced Score

| Web Service Systems for Cooperative Work Support in Knowledge Creation Processes | | BIBAK | Full-Text | 94-103 | |
| Hiroyuki Kojima; Kentaro Funaki; Tsuyoshi Inoue | |||
| The emergence of Web service results from the business needs as mentioned
below. Web service as the evolution of software engineering is also required to
explore the possibility of adapting to cooperative work support with knowledge
management. Web service technology is becoming the focus of interest as an open
standard for web software, because of its service-oriented architecture. Web
service facilitates Internet commerce, or e-commerce, because it enables the
execution of inter-organization in a typical business application or logic area
such as dynamic supply chain composition. Web service technology is successful
in the above business with a fixed procedure. It is therefore desirable to
adopt an atypical task requiring a wide variety of task procedures. This
research focuses on a method of applying Web service to atypical tasks with a
non-fixed procedure, such as a knowledge creation task, to improve the task
performance in a cooperative work. The results presented in this paper are
expected to validate the performance of Web service in carrying out a dynamic
search for a document from various information resources. Keywords: Web Services; Knowledge Sharing; Document Retrieval; Cooperative Work

| Proactive Fault Detection Schema for Enterprise Information System Using Statistical Process Control | | BIBAK | Full-Text | 113-122 | |
| Chihoon Lee; Doohyung Lee; Jahwan Koo; Jin-Wook Chung | |||
| This paper proposes a proactive fault detection schema using adaptive
statistical approaches in order to enhance system availability and reliability
in the heterogeneous & complicated information system environment. The
proposed system applies Six Sigma SPC (Statistical Process Control) techniques
already validated in industries in order to monitor the application system in
the information system. This makes it possible to reduce false alarm rates for
system faults and accurately detect faults by creating a control chart based on
past performance data and controlling the distribution of performance based on
the chart. The early detection of faults is also enabled through a fault
prediction model. Therefore, the aforementioned system not only detect unknown
or unseen faults but also resolve potential problems for system administrator
by detecting abnormal behaviors before faults occur. In the experiment we show
the superiority of our proposed model and the possibility to early detect
system faults. Keywords: System management; Proactive Fault detection; Statistical Process Control;

| Chiuhsiang Joe Lin; Chih-Wei Yang; Shi-Bin Lin; Shiau-Feng Lin | |||
| The implementation and adoption of enterprise resource planning (ERP) system
is currently a key issue for companies. The critical problem of implementing
and adopting ERP system is that the system architectures are quite complex.
This study focuses on the integration of the human factors issues in the ERP
implementation process. The mental or cognitive differences between information
systems concerning people and end users are compared in this study based on
information related theories. This paper proposes a human-centered system
implementation and adoption model. The main purpose of this model is to assist
the ERP system implementation and adoption and creates maximum customer value.
The paper shows how to carry out the model step by step with the final goal of
increasing the efficiency and acceptability of the system to be implemented and
adopted. Keywords: Enterprise resource planning; human factors; human-centered; information

| A Study on Effective Methods of Visual Inspection for Reused-Parts by Inspectors | | BIBA | Full-Text | 131-139 | |
| Toshiyuki Matsumoto; Hideki Shirai; Keisuke Shida | |||
| In order to promote recycling in the recycling industry, it is essential that suppliers perform a strict inspection before shipping the products using reused or recycled parts. The industry is facing pressures to further improve and standardize inspection quality and efficiency on recycled parts or products. This study thus developed an effective visual inspection method for products using reused parts by inspectors at Recycling Plant N, for assuring product quality. First, a survey was conducted to investigate the current situation at the subject plant. Secondly, another set of surveys was conducted for the 13 inspectors. The survey included a video analysis, a questionnaire survey analysis, and an analysis of eye movements using an eye-tracker, and after the analyses, the differences were specified. Thirdly, by considering the inspection method and inspection orders used by the experienced inspectors, appropriate inspection items, inspection order, and inspection method could be devised. | |||
| Practical Use of Task Models for Building and Modeling Operations Chart in the Industrial Production | | BIBAK | Full-Text | 140-148 | |

| In this paper, we will show how hierarchical task modeling can give
beneficial support for the specification and validation of a production process
in its early development stages. This will be done with respect to the growing
challenges coming from the market environment. In particular, it is a
substantial benefit to use an adequate modeling environment to be able to take
specific customer requirements process during the production planning into
account. For our methodology, we use Amboss, a task modeling environment
designed for safety-critical socio-technical systems. Keywords: Hierarchical Task Models; Expert System; Process Modeling; Production

| Exploring Employee Perspectives on Information Privacy and Security in the Mobile Environment | | BIBAK | Full-Text | 171-180 | |
| Peter Tarasewich; Benjamin Ngugi; Mansi Sanghavi | |||
| Maintaining information privacy and security in the mobile environment, an
issue having personal and organizational implications, remains a challenge
because the context of a mobile device can change rapidly. In response to this,
the authors have been investigating methods of maintaining the privacy of
sensitive information accessed in mobile environments (i.e. potentially in
public places). This particular study, still in progress, will collect and
analyze data on employee information privacy and security practices and
perceptions. A complicating factor is that the classification of information as
"private" may not be absolute. Privacy levels of organizational information
will be dictated by company policy, while privacy concerns with personal
information are based on the employee's own comfort level. Hence potential
conflict arises if an individual uses a single mobile device for both personal
and organizational information access. A summary and status of design
activities and the planned implementation of the study is provided. Keywords: privacy; security; information; mobile; context; organization | |||
| Organization Diagnosis Tools Based on Social Network Analysis | | BIBA | Full-Text | 181-189 | |
| Takanori Ugai; Kouji Aoyama | |||
| Many organizations have challenges such as inter-organizational barriers and motivation of employees. However, these kinds of problems are not easy to visualize, and it is even more difficult to derive, implement and assess appropriate measures to deal with them. We developed a tool to visualize the dynamic structure of cooperative relationships between employees in organizations based on questionnaires given to employees of those organizations. This tool is used for visualizing barriers between teams and the effects of measures. In this paper we explain some features of this tool and verify its capabilities and effectiveness with a case study. The case study is some field research based on interviews that we conducted in which we applied measures to improve the employees' communication. We collected a set of data about relationships in an organization with questionnaires before and after implementing the measures. And we compared the observed result produced by the visualization tool with the result from the field research. | |||

| Research on the Supplier Promise Management Based on the Lean Six Sigma | | BIBAK | Full-Text | 205-213 | |
| Wang Ying-chun; Wang Shi-jie; Liu Yong-xian; Zhang Xinmin | |||
| In the supplier management, the supplier promise management is one important
area. The scope of the supplier promise is very widespread, such as the promise
of HSE (health environmental safety), the promise of quality, the promise of
price, and the promise of delivery performance etc. As one character of one
enterprise the promise has become the most significant evaluation factor which
was used to select the supplier for the upstream firm. So during the modern
production and management, how to help suppliers to improve their performance
to promise has become one key problem. Evidently the nature of this problem is
usually complex and unstructured. The paper tried to utilize Lean Six Sigma to
solve the problem of the supplier promise management. Such creates a new point
of view to study and control the supplier promise management. Lean Six Sigma is
an new advanced and high efficient method of management which combined the
virtues of Lean production and Six Sigma Management. It focus on the subtle
production and the strategic management simultaneously. The three key elements
which were attach importance of the modern companies are velocity, cost and
benefits, as well as the modern supplier promise management. To use the
thinking of the lean Six Sigma in the supplier promise management will bring
greater economical benefits than before. In this paper one example which is
about the supplier performance to promise date is discussed. The results show
that to apply the Lean Six Sigma into the supplier promise management is more
practical and effective than the other managing ways. Keywords: Lean Six Sigma; Supply Chain; Supplier Promise Management; Procession | |||
| Supporting Scenario-Based Product Design and Its Adapters: An Informal Framework for Scenario Creation and Use | | BIBAK | Full-Text | 217-226 | |
| Irene Anggreeni; Mascha van der Voort | |||
| This paper proposes a support tool for designers who have realized the
potential benefits of using a scenario-based approach, yet need a more concrete
guidance for its implementation. As an informal framework for scenario creation
and use, the tool supports three areas: (1) documenting the large amount of
design information, (2) making sense of and summarizing the information by
creating scenarios, and (3) sustaining an integrated use of the scenarios
throughout the design process. By making explicit and supporting the process of
using scenarios, we expect that designers can better structure their design
information, communicate their ideas and confirm their rationales. Our ongoing
work includes the verification of the tool concept and the development of a
testable prototype. Keywords: scenario based design; product design; scenario based product design;

| How to Learn from Intelligent Products; The Structuring of Incoherent Field Feedback Data in Two Case Studies | | BIBAK | Full-Text | 227-232 | |
| Renate de Bruin; Yuan Lu; Aarnout Brombacher | |||
| A growing number of products -- particularly highly innovative and
intelligent products -- are being returned by customers, while analysis shows
that many of these products are in fact functioning according to their
technical specifications. Product developers are recognizing the need for
information that gives more detail about the reason for these product returns,
in order to find the root cause of the problems. Traditionally a lot of
information from the field is stored in departments like sales and service
(helpdesks and repair centers). Combining these data sources with new field
feedback data sources, like customer experiences on the internet and product
log files, could provide product developers with more in-depth and accurate
information about the actual product performance and the context of use. Case
studies were done at two different industries: a company from consumer
electronic industry and a company from professional medical system industry.
The Maturity Index on Reliability (MIR) method, a method to assess capability
for businesses to respond to product reliability related issues, was combined
with Contextual Design, a method for user context mapping and requirement
definition, and explored as a means to analyze the structure and capability of
the current field feedback process in supporting the development of complex and
innovative products. Keywords: Field Feedback Data; Product Failure; Root Cause Analysis; Business

| Successful User Experience in an Agile Enterprise Environment | | BIBAK | Full-Text | 233-242 | |
| Melissa Federoff; Catherine Courage | |||
| Salesforce.com is a leader in the enterprise Customer Relationship
Management (CRM) marketplace. In 2006, salesforce.com's Research and
Development (R&D) organization transitioned over 30 product teams from a
waterfall development process to an agile one. The R&D department is
responsible for producing all products offered to salesforce.com customers.
After the transition, it was clear that User Experience (UX) team members were
dissatisfied. When asked 6 months into the rollout if agile was making their
work life better, only 24% agreed. This paper discusses how the team and
management responded to this data and as a result reached an 85% satisfaction
rate a year later. Keywords: Agile; waterfall; enterprise; user experience; design; research | |||

| How Product Differentiation Affects Online Shopping | | BIBAK | Full-Text | 253-262 | |
| A. Walkyria Goode | |||
| Online product comparison sites aid consumers in making purchase decisions
by providing information regarding product attributes, reviews and retailers.
Despite the enormous research on information processing and consumer behavior,
little has been directed at investigating how information display impacts
online purchase choices. Cognitive theory is used to evaluate whether the order
in which consumers receive information influence their decision making. An
experiment with 60 participants was performed. Results indicate that no order
effects mediated choice among alternatives with equal utility. However,
preference was observed for a particular type of product. While all the
products had the same overall rating, this product had both a larger number of
high and low ratings. It is suggested that this was a sufficient condition to
differentiate the product listed in this position from the other products. Keywords: consumer choice; product differentiation; order bias | |||

| Ying-Jye Lee; Cheih-Ying Chen; Fong-Gong Wu | |||
| The customized product color interface based on scenario experience is
defined as the experienced marketing model in this study. There are 48 color
combinations of the spatial image resulted from four scenario styles and 12
popular sofa colors. The image compositing technique is adopted to appear the
48 color combinations of the spatial image on computer screen. This study
compares the difference between the experienced marketing model and traditional
marketing model by using the evaluation items of Personal Involvement
Inventory. Results show that eight evaluation items including interesting,
exciting, means a lot to me, appealing, fascinating, valuable, involving, and
needed for the experienced marketing model are significant better than the
traditional marketing model. Besides, two evaluation items including important
and relevant doesn't appear significance between the two models. Therefore, the
entrepreneur who wants to display the color primarily commodity should design
the customized color combination interface with scenario experience for
consumers to take opportunity to find the appropriate products to meet with
consumers' needs, so as to shorten communication time between entrepreneurs and
consumers. Keywords: Customized product; Color combination; image compositing technique; Personal

| Distribution of Human-Machine Interfaces in System-of-Systems Engineering | | BIBAK | Full-Text | 271-278 | |
| Sandro Leuchter; Dirk Mühlenberg | |||
| System-of-systems integration requires sharing of data, algorithms, user
authorization/authentication, and user interfaces between independent systems.
While SOA promises to solve the first issues the latter is still open. Within
an experimental prototype for a distributed information system we have tested
different methods to share not only the algorithmics and data of services but
also their user interface. The experimental prototype consists of nodes
providing services within process portals and nodes realizing services with
software agents. Some of the services were extended with WSRP (web service
remote portlet) to provide their own user interface components that can be
transmitted between separated containers and application servers.
Interoperability tests were conducted on JBoss and BEA Portal Workshop. Open
questions remain on how the layout of one component should influence the
internal layout of other GUI-components displayed concurrently. Former work on
user interface management systems could improve todays tools in that respect. Keywords: HMI; portlet; wsrp; web clipping; interoperability | |||

| Reversing the Simon Effect with Prior Practice of Noncorresponding Location Words | | BIBAK | Full-Text | 287-295 | |
| Andrea Rottermann; Kim-Phuong L. Vu | |||
| A benefit for spatial correspondence, called the Simon effect, is typically
obtained in choice-reaction time tasks when the stimulus location is irrelevant
to the task. Reversal of the Simon effect to favor noncorresponding
stimulus-response locations has been obtained for physical-location stimuli
after minimal practice (84 trials) with an incompatible spatial mapping. After
practice with location-word stimuli, the Simon effect for physical locations is
not reduced. The present study evaluated whether practice with "incompatibly"
mapped location words can reverse the Simon effect when the practice session
emphasizes color-to-response mappings rather than spatial mappings. Two
conditions were tested in which the proportion of noncorresponding to
corresponding trials was manipulated in the practice session. A full reversal
was evident when all trials in the practice session were noncorresponding.
Implications for interface design are discussed. Keywords: Simon effect; stimulus-response compatibility; practice-transfer paradigm | |||
| Object-Oriented Interactive Processes in Decentralized Production Systems | | BIBAK | Full-Text | 296-305 | |
| Thomas Schlegel | |||
| Supervision and controlled execution of processes and parameters are core
requirements in Digital Production. But even in rather homogeneous systems,
deviation from defined workflows and even process change occur daily. To be
able to react flexibly to changing market conditions and to respond to
increasing individualization of products and their adjacent processes, even
more and ad-hoc variants have to be created and supported by production
planning and control systems. We solve this problem by introducing a semantic
process model, which can be executed and extended using a decentralized,
message-based system. In situations where unforeseen deviations and needs for
interactive intervention occur or ad-hoc input from users is needed, a generic,
model-based user interface is used to create correct interactions in such a
context. Our contribution makes processes much more flexible and opens up a new
way of creating correct interactions in unforeseen process contexts. Keywords: Interactive Processes; Process Models; Meta-Models; Production Systems;

| The Information Technology (IT) professional's user experience has evolved
both in terms of software tool attributes and the process workflow within which
the IT tasks exist. Based on user research with IT professionals over the past
two decades, including ethnographic observational field studies, focus group
discussions, and hands-on user tests with analyses of errors and perceived
complexities, this paper presents a set of hypotheses about user interface
design aspects that across the industry most impede the workflow of typical IT
professionals. It discusses how this relates to typical information workers'
behavior, as well as what steps we as tools and systems designers can take to
better support the IT professionals' user interface needs. Keywords: IT professional; enterprise software; user interface; user experience; UI

| Traditional user-centered design processes do not leverage long-term
customer-vendor relationships as a means of improving product usability. While
designing a next-generation applications software suite, Oracle reached out to
its most-involved customers for creative solutions to common user-experience
issues. The mission of the Oracle Usability Advisory Board was to take
enterprise software to a whole new level in usability. The board consisted of
executives and senior managers primarily in information technology positions in

| Fashion Support from Clothes with Characteristics | | BIBAK | Full-Text | 323-330 | |
| Yuri Yonezawa; Yoshio Nakatani | |||
| Fashion can be a source of daily enjoyment, as well as source of anxiety, in
our lives. In this paper, we propose a new system for supporting a person's
fashion coordination. This system produces pleasant coordination between a
person and his or her clothes when the person stands in front of the closet
each morning and picks out the day's attire. Each item of clothing has its
corresponding software agent with a specific characteristic decided by color,
based on psychological findings. The scenario is as follows: First, the user
enters the total fashion image for the desired fashion profile for the day,
such as "today's image is red." When the user goes to the closet, clothing that
is red or verging on red start to appeal. The user hears messages such as
"Choose me because you had a good day last time you chose me," and "No, choose
me because it is hot today." An Integrated Circuit (IC) tag is put on each
hanger, and the chosen article of clothing is identified by the IC tag reader
affixed to user's finger. The episodic database and the database of basic
fashion knowledge are connected to each as a knowledge source for conversation. Keywords: fashion; coordinate; software agent; IC tag | |||
| Exploring History with Narrative Timelines | | BIBAK | Full-Text | 333-338 | |
| Robert B. Allen; Sumanth Nalluru | |||
| We develop novel timeline interfaces which separate the events in timelines
into threads and then allow users to select among them. This interface is
illustrated with five threads describing the causes of the American Civil War.
In addition to selecting each of the threads, the sequence of events it
describes can be played. That is, the user can step through the sequence of
events and get a description of each event in the context of its thread. In
addition, many of the events have links to more focused timelines and to
external resources such as Wikipedia. Keywords: Causation; Events; History; Interactivity; Narrative; Timelines;

| Facilitating Search through Visualized Results | | BIBA | Full-Text | 339-344 | |
| Takahisa Ando; Satoko Shiga; Tomoya Iwakura; Seishi Okamoto | |||
| This paper presents a search engine interface enriching search results with thumbnails of documents such as reports, presentation materials, spreadsheets, and so on. Usual search results consist of text information, such as the title and its snippet of each document. Our interface adds the thumbnails of documents listed in search results for assisting the search processes of users. We evaluate the interface on a web site search engine. The experimental results show that our interface enables users to find their target documents more efficiently than using an interface without thumbnails. | |||
| The 7 Basic Functions of a Digital Library -- Analysis of Focus Groups about the Usefulness of a Thematic Digital Library on the History of European Integration | | BIBAK | Full-Text | 345-354 | |
| Eric Brangier; Jérôme Dinet; Laurent Eilrich | |||
| This paper presents the main results of a study involving an original
user-centred design approach to modify and improve a specific digital library
(DL) related to the history of European integration. The ultimate goal of the
project is twofold: (1) to find ways to improve end-users' use of this thematic
DL; (2) to develop an original method to measure real users' needs and mental
representation. This user-centred approach is based on focus groups, this
technique being a powerful means to evaluate services or test new ideas. In our
study, more precisely, focus groups were set up by conducting interviews with
58 users (researchers, professionals in documentation, journalists, historians,
teachers, students, ergonomists, politicians, computer engineers, etc.), but
including four to five people at the same time in the same group. Each of these
14 focus groups was videotaped for a 3-hour period and all verbalisations
(needs, viewpoints, etc.) were transcribed. Our analysis showed that the users'
needs can be expressed through seven basic functions which match the users'
expectations. This paper brings together the process by which these functions
were identified and also discusses the interests, limitations and possible
generalisations of these functions in the context of all digital libraries. Keywords: digital library; functions; function analysis; user-centred design; user
requirements; user needs; ENA; European integration | |||
| Exploiting Browsing History for Exploratory Search | | BIBAK | Full-Text | 355-364 | |
| Wei-Lin Chen; Wei-Guang Teng | |||
| With the advance of information technologies, web search has become a
necessary activity for most Internet users. Although current search engines are
powerful enough to respond required search results in seconds, information
seekers may still feel arduous to digest them when conducting the exploratory
search. In other words, when users are unfamiliar with the domain of their
goals or unsure about the ways to achieve their goals, they may need to read
numerous pages before fully understand what they are searching for. In this
work, we propose to fully exploit the browsing history to help users clarify
their thoughts and discover new insights during the process of exploratory
search. Specifically, interactive user interfaces of two different modes, i.e.,
the timeline mode and the relevance mode, are devised to provide users a vivid
impression of their browsing history. Hopefully, the feasibility and usability
of web search for users can be further improved. Keywords: Exploratory search; information seeking; interactive interface; timeline | |||
| A Proposal of Awareness Services for the Construction of Quality Community Knowledge Supported by the Knowledge Management System KnowCat | | BIBAK | Full-Text | 365-374 | |
| Ruth Cobos Pérez; Ivan Dario Claros Gómez; Jaime Moreno-Llorena | |||
| It is well known that members of work groups need awareness about one
another, about shared elements, and about the group process. We present a
generic framework of awareness services for groupware systems. The proposed
approach has been tested through the implementation of a prototype composed by
several awareness services for the Knowledge Management system called KnowCat.
KnowCat is a groupware that supports the collaborative construction of quality
community knowledge. We carried out a research study with a group of students
enrolled in a graduate course at Universidad Autónoma de Madrid (Spain)
to test our approach. The study outcomes corroborated that providing to the
KnowCat users the most useful information about how the classmates have
interacted with the system through the awareness services, can help them to
know how they should solve their own work in the system and to be aware that
they are working in a collaborative way. Keywords: Awareness; CSCW; Groupware; Knowledge Management; Learning communities;

| Search Mathematical Formulas by Mathematical Formulas | | BIBAK | Full-Text | 404-411 | |
| Yoshinori Hijikata; Hideki Hashimoto; Shogo Nishida | |||
| Users cannot search information by mathematical formulas as queries in
existing search engines. This is because mathematical formulas are not
expressed as a sequence of characters. Some formulas are expressed in a complex
structure like fractional numbers and index numbers. We present a search engine
for MathML objects using the structure of mathematical formulas. The system
makes the inverted indices by using the DOM structure of the MathML object. We
proposed three types of index. One type is constructed from some paths of the
DOM structure and expressed in XPath. The other type is constructed by encoding
the nodes in the same level in DOM structure. The third type is a hybrid method
of them. This paper describes the experiment conducted to study the
effectiveness of those indices. Keywords: MathML; search engine; mathematical formula; index; inverted file | |||
| Metadata-Based Reminder Classification in Reminiscence Engineering | | BIBAK | Full-Text | 412-418 | |
| Masashi Ishibashi; Yoshio Nakatani | |||
| Our personal memory project studies a new framework which supports people
construct the personal history on the computer. In this paper, we propose a
framework of reminiscence engineering in order to classify reminders of
personal memories. The reminders include photos, videos, gifts from significant
people and so on. Today the reminders have been digitized, such as digital
photos, and the amount of them keeps on increasing and the necessity of
managing these digital reminders is also increasing. This system supports to
manage reminiscence by classifying the digital reminders based on their
metadata. The metadata in this research means the data about digital photos,
such as the date and time at which it was taken, objects and the related
memories. In order to classify these metadata, the system provides the
vocabulary database that structures vocabulary necessary to classify the
digital photos. We propose an effective framework which supports construct the
vocabulary database through the entry of personal memory, as well as construct
personal memory through the entry of new vocabulary. Keywords: personal memory; classification; ontology; metadata | |||

| We propose a system called InfoScape for exploring large histories of user
behavior including location data (latitude and longitude). User behavior
patterns are created from the histories of user behavior from data sources such
as life logs. The browser of this system can find user behavior patterns by a
query for a user behavior pattern. Currently, the histories of user behavior
consist of 9,324 records. As a result, this study investigates the most
effective conditions for the operation of this system working and demonstrates
with factors are location and time for creating user behavior-based feature
patterns. Keywords: Context-aware computing; information retrievals; neural networks; ubiquitous

| In this paper, the roles of selected individual difference factors were
examined in some personal information management (PIM) tasks. A questionnaire
was completed by 295 participants regarding their personal characteristics,
retrieval of previously saved information, and selective use of multiple
computers. Clustering of individual difference factors suggested further
analysis of profession and gender as classifiers. Profession seemed to modulate
the behaviors and attitudes of users in these PIM tasks. And certain gender
difference in PIM tasks could be explained by different expectations or
standards. Keywords: Personal Information Management; Profession; Gender | |||
| Efficient Text Classification Using Best Feature Selection and Combination of Methods | | BIBA | Full-Text | 437-446 | |
| Mettu Srinivas; K. Pujari Supreethi; E. V. Prasad; S. Anitha Kumari | |||
| Lsquare and k-NN classifiers are two machine learning approaches for text classification. Rocchio is the classic method for text classification in information retrieval. Our approach is a supervised method, meaning that the list of categories should be defined and a set of training data should be provided for training the system. In this approach, documents are represented as vectors where each component is associated with a particular word. We propose voting method and OWA operator and Decision Template method for combining classifiers. In these we use an effective and efficient new method called variance-mean based feature filtering method of feature selection. Best feature selection method and combination of methods are used to do feature reduction in the representation phase of text classification is proposed. Using this efficient feature selection method and best classifier combination method we improve the text classification performance. | |||
| Designing Sticky Knowledge-Network SNS for Japanese Science Teachers | | BIBAK | Full-Text | 447-456 | |
| Yoshihisa Wada; Masayuki Sakoda; Hiroshi Tsuji; Yuuki Aoki; Kazuhisa Seta | |||
| To support knowledge sharing among science teachers on ICT (Information and
Communication Technology), this paper proposes a knowledge-network SNS (Social
Networking Service) based on stickiness, which have three factors to drive; (I)
Relationship Capital, (II) Reputation and (III) Personalization. Building a
prototype SNS based on these factors, this paper defines two kinds of
quantification of stickiness which express how system is used and how user
continue to use. Compared with the traditional knowledge-repository, the
knowledge-network SNS transfers tacit knowledge learned in class from one to
others. And more, the quantificated stickiness gives standards to strengthen
teachers' knowledge-network; (1) picking up low-stickiness teachers for
inviting into the network and (2) estimating stickiness of the system. Keywords: ICT; Knowledge-Network; Stickiness; Social Networking Service | |||
| A Proposal of EMG-Based Training Support System for Basketball Dribbling | | BIBA | Full-Text | 459-465 | |
| Seimei Abe; Takayuki Nozawa; Toshiyuki Kondo | |||
| In the paper, we propose a novel HCI methodology for supporting human sports training. The proposed system utilizes electromyogram (EMG) signals as the metrics for evaluating the motor skill acquisition process, because it is well known that EMG signals measured from human experts are notably different from beginners in terms of timing and sharpness. According to this, we hypothesized that visualizing the difference of EMG signals between an expert and a learner, and providing the error information to the learner in real-time accelerates the learning process. The preliminary results show that the proposed method is effective especially in the early stage of training of beginners. | |||
| UbiSOA Dashboard: Integrating the Physical and Digital Domains through Mashups | | BIBA | Full-Text | 466-474 | |
| Edgardo Avilés-López; J. Antonio García-Macías | |||
| The current Web 2.0 stage of the Internet provided the basis for web-based communities and services aimed at collaboration and information sharing. Furthermore, Internet is now an application platform in which Web applications can be integrated to provide augmented services that could bring the basis for ubiquitous computing scenarios. Recently, the concept of mashups has been used to refer to applications built upon the integration and combination of public Web API's and data sources. Ubiquitous computing mashups go further by combining the functionality of both software and hardware components in an attempt to exploit computation and services provided by everyday objects. Typically, developing a mashup requires highly specialized knowledge in many topics (such as using different programming interfaces and languages). This problem is greatly magnified in developing mashups of both physical and digital services due to the various integration and communication issues. We exemplify these concepts through the use of UbiSOA Editor, a system that allows the creation of ubiquitous computing mashups through simple activities such as dragging and dropping graphical representations of the involved services in a desired scenario. Then we talk about the planning and execution of a sample scenario as a showcase of what can be easily accomplished. | |||
| Internal Aspects of the Relationship between Pressing Force and Training Difficulty | | BIBA | Full-Text | 475-484 | |
| Daisuke Doyo | |||
| In manual assembly work, parts are often assembled by applying force with a simple tool or by hand. A worker thus needs control the force he or she applies in working, as an appropriate level of force is requisite for minimizing work failures and improving efficiency. The object of this study is to clarify the relationship between the level of force (the "force") and level of training difficulty (the "training difficulty") in manual assembly work. Measurements of the training difficulty for 10 test subjects (persons being tested) at force gauges of 30, 40, 50, 60, 70, 80, 100, and 120N revealed a relationship between the force gauge internal to each test subject and the training difficulty. | |||

| Wearable computing has the image of the high-level information processing
which uses the small-sized computer. However, a motion of the body is barred by
the complexity of wiring or apparatus and the function of assistance of
operation which is the function of original dress is disregarded in many cases.
Moreover, it tends to be kept at a distance that externals look like the cyborg
by a general person. On the other hand, the interface that uses the movement of
the body recently is actively researched. Then, the prototype system of a good
design and fit was developed for the college woman and evaluated in this
research. The system has the touch interfaces that pay attention to touch
communications and can do the music sharing and the voice conversation by
two-way, and the switch can be done by touch. Keywords: Touch Communication; Wearable Interface | |||

| Yuka Koda; Maki Taniguchi; Yukiyasu Kamitani; Naoki Saiwaki | |||
| This research examined a tactile objective evaluation using ICPF (Ionic Conducting Polymer gel Film) actuators and real materials paying attention to the brain activation. The ICPF actuator is a display that presets artificial tactile feelings like fabrics, which we presented in HCI International 2005 [1]. The procedure of this evaluation method is as follows. 1: applying four kind of artificial tactile stimuli to subjects in f-MRI chamber, 2: measuring of the brain activity by f-MRI, 3: analyzing the difference between the brain activities evoked by different stimuli, revealed by decoding method, 4: examining an effectiveness of the result. In addition, we prepared four real materials tactile stimuli for comparison. Experimental results showed that a human brain could classify significantly both real materials and artificial tactile stimuli and that we could confirm them by decoding method with f-MRI. This fact derived the idea that measuring brain activity was one example of tactile feeling objective evaluation method. To verify the idea, we carried out a test with stimuli that narrowed the tactile gap. This experiment showed an insignificant result from its decoding value. But, the decoding results of all subjects exceeded a chance level. The chance level is chance of success in this paper. These experiment results didn't deny the brain activity measurement by f-MRI as a technique for evaluating the sense of touch and the effectiveness of the decoding method. Therefore, it is thought significant researching continuously in the further. | |||
| Using 3D Touch Interaction for a Multimodal Zoomable User Interface | | BIBA | Full-Text | 543-552 | |
| Florian Laquai; Markus Ablaßmeier; Tony Poitschke; Gerhard Rigoll | |||
| Touchscreens are becoming the preferred input device in a growing number of applications. They are interesting devices which are more and more introduced into the automotive domain. Current implementations impose problems like precise pointing or high visual attention and therefore the capabilities of projected capacitive touchscreens are investigated. Unlike traditional sensing techniques like resistive or optical measurements, projected capacitive sensors register the presence of a hand or finger even before the actual touch. This enables such devices to be used not only for 2D input but for interaction using the position and distance of the users finger relatively to the screen. The additional distance information is then applied to control a Zoomable User Interface. In this study touch and speech interaction is being applied to allow fuzzy input and lower visual attention demand than conventional Touchscreens. A demonstrator was developed using the mentioned input strategies for the automotive domain and finally evaluated in a user study. | |||

propose modifies the algorithm of the PLUS system that uses the GT4 toolkit and
suggests improving flexibility by partitioning the normal reservation sector
from the advanced reservation sector. With this partition, we are able to offer
a more guaranteed use of normal resources. After we have discovered the

| Traditional e-mail notification applications, which notify the user of newly
arrived messages, are frequently insufficient because users daily receive a
vast number of messages. Hence, we propose an e-mail notification application
that peripherally displays summaries of messages in the form of kinetic
typography. In addition, it infers the possibility of a message being read to
control notification levels and conceals parts of words to avoid exposing
excessive personal information. We have qualitatively confirmed the effects of
the application through trial use; it can strongly attract users' attention and
motivate the user to check significant messages. Keywords: notification; kinetic typography; peripheral display; ambient display | |||

| A Study on Color Conversion for Color Deficient People to Identify Color | | BIBA | Full-Text | 594-600 | |
| Makoto Oka; Naoki Ozawa; Hirohiko Mori; Akito Sakurai | |||
| The sensitivity of the M-cones and L-cones of an anomalous trichromat is lower than that of normal trichromats. By intensifying the light to the cones with lower sensitivity, the output ratio from the cone approached the level of a normal trichromat, and it was presumed that achieving close to original color recognition was a possibility. In order to increase luminous intensity, in the LMS space, the boundary was set as the plane surface representing pseudoisochromatic color, and the distance from that plane was expanded. When making large changes in light intensity near the surface representing pseudoisochromatic color, improvements in color differentiation and degree of color identification were observed. We plan to implement this method in mobile devices and to evaluate the experimentation results. | |||
| Widgets for Faceted Browsing | | BIBAK | Full-Text | 601-610 | |

| Faceted Browsing, also known as Faceted Search, recently became a popular
interface paradigm and is used as a visual selection mechanism to browse data
collections. It is particularly suitable for structured, but heterogeneous data
with explicit semantics. As the amount of this data will grow in respect to a
rising Semantic Web, it is worth looking at the current state of Faceted
Browsers. In this paper we extract characteristics of several browsers from
various domains. We then propose the use of advanced widgets for Faceted
Browsers and how to select appropriate widgets. Keywords: Faceted Browsing; Faceted Search; Dynamic Taxonomies; User Interface;

with jetting mists along light axis of a laser pointer. The estimation accuracy
for the position of a laser spot occluded behind an object was improved when
the light path of the laser was visualized. In this paper, we propose visible
light path laser projector (VLLP) for remote collaboration. VLLP is equipped
with a laser projector and a mist generator. With the laser projector, VLLP can
instruct with not only a laser spot but also simple line drawings. Furthermore,
we propose several VLLP application prototypes. Keywords: Remote collaboration; Visible Light Path Laser; VLLP; Laser projector | |||
| Virtual Convex Polygon Based Hole Boundary Detection and Time Delay Based Hole Detour Scheme in WSNs | | BIBAK | Full-Text | 619-627 | |
| Inyoung Shin; Ngoc Duy Pham; Hyunseung Choo | |||
| In wireless sensor networks, an important issue often faced in geographic
routing is the "local minimum phenomenon." To mitigate the local minimum issue,
when the routing process becomes stuck at hole boundary nodes, the existing
perimeter routing tends to route data packets along the boundaries of the
holes. However, this may enlarge the hole, causing the "first hole diffusion"
problem. On the other hand, the existing hole detour scheme based on the
virtual ellipse forwards data packets to outside the virtual ellipse. This may
generate other holes around the existing hole -- the "second hole diffusion"
problem. Therefore, we propose a novel virtual convex polygon based hole
boundary detection and time delay based hole detour scheme. The proposed scheme
solves first and second hole diffusion problems. Comprehensive simulation
results show that the proposed scheme provides approximately 22% and 16%
improvements in terms of the packet delivery ratio and the network lifetime,
respectively. Keywords: Wireless Sensor Networks (WSNs); Geographic Routing; Hole Problem | |||

| An Interactive System Based on Semantic Graphs | | BIBAK | Full-Text | 638-647 | |
| Johann Vandromme; Samuel Degrande; Patricia Plénacoste; Christophe Chaillou | |||
| This paper introduces an original method towards post-WIMP desktops. Our
main contribution involves a new way of organizing desktops with respect of the
Instrumental Interaction model and relies on semantic graphs. A semantic graph
expresses semantic dependencies of documents or components like a scene graph
expresses geometrical dependency. This structure allows users to visualize the
desktop given a chosen criterion. We also propose polymorphic tools that enable
Direct Manipulation: tools directly modify the semantic visual factor leading
to a semantic modification of object. A prototype is proposed to illustrate
this concept. Keywords: software design; interfaces; graphs; semantic; desktop; tools | |||

| We have developed AR-Navi, an in-vehicle navigation system that captures
real-time video via an in-vehicle camera and overlays guidance on a video
display. In this study, we conducted a driving experiment to evaluate the
location-adjustment-method of AR-Navi. We also discuss the registration
accuracy of the route guidance that AR-Navi gives at intersections. Keywords: Augmented reality; In-vehicle navigation systems; Route guidance | |||
| Improving the User Experience of Our Own UX Ideas | | BIBAK | Full-Text | 659-664 | |
| Joel Eden | |||
| Systems thinking is a perspective that focuses on looking at interdependent
relationships between entities in an organization, making visible otherwise
hard to see leverage points. Evaluation is an inherent part of designly
thinking, even though many practicing UX professionals view evaluation as
something that follows "design." These two views are discussed related to
understanding how to get more traction for our UX ideas in the existing design
processes within our organizations. Keywords: User Experience; Systems Thinking; Evaluation as Design | |||

| Data Pattern for Allocating User Experience Meta-Data to User Experience Research Data | | BIBAK | Full-Text | 675-684 | |

| The vision of user experience is making life of users of products as
convenient as possible, especially during the interaction with a productor a
service. An important aspect of perceived convenience is the user experience of
a product. The visual design and especially the interaction design has a major
influence on this perception. In order to achieve the vision, user experience
experts apply different types of tasks. One type of task is to analyze how
users carry out tasks and what user's needs or problems are. Another type of
task is to design user experience solutions and other typical task type deals
with carrying out usability evaluations in order to find problems in using
software application. In the course of user experience activities, many data
are being collected. Many of the collected data relates to certain activities
of users. For the user experience area there exist just a few tools, which
support typical tasks in different ways. None of the tools supports linking
results of user experience work to user experience meta-data. Why is it a
problem? The current tools do not support an access to user experience project
data with generic search and filter criteria like "industry", "application
area", "use case" etc. This makes the access to user experience research data
difficult and the comparison of user experience project data between different
projects inefficient. In general, results of different user experience projects
are difficult to reuse. The core idea of data pattern for allocating user
experience Meta-Data to User Experience research data is to associate user
experience project data with user experience meta-data. The data pattern
considers associating user experience project data with user experience
meta-data partially automatically and partially manually by the user. The key
idea is that we want to reuse project data like the project sponsor, the
application area, the industry, use cases etc. as user experience meta-data and
assign them to user experience research data. The benefits of the data pattern
are: Reusing results of user experience research projects. Making access to
available results more efficient. Direct comparison of available results is
supported and more efficient. UX Office is the typical instance for
application. Keywords: User Experience; Project Data; Research Data; Meta-Data | |||
| Transcending Human-Centered Design by Service Sciences | | BIBAK | Full-Text | 685-692 | |
| Hiroyuki Miki; Naotsune Hosono; Sakae Yamamoto | |||
| Human-Centered Design (HCD), which emphasizes the user's point of view, has
brought many good results to date. For instance, with detailed analysis of
user's context of use, developers of products and services can make them easier
to use. Despite such good results, some limitations of HCD have also been
pointed out. For example, since most methods of HCD are qualitative, they
require exhaustive work every time with small improvements in efficiency.
Although many qualitative quick methods have been proposed and tried to solve
the problem, their results have not brought big differences. On the other hand,
in the area of Service Sciences (SS), quantitative methods that explicate
details of human activities based on a large number of data have brought some
good results in producing new added-values and higher efficiency. Methods in SS
emphasize the users' point of view as with those in HCD, and have come to be
associated with innovation theories. Considering these current situations, this
research emphasizes the users' viewpoint and combines HCD, SS, and innovation
theories to come up with new methods that lead to new added-values and higher
efficiency. As an initial effort of the research, this paper first clarifies
relations between HCD, SS, and innovation theories, and then discusses issues
in transcending HCD. Keywords: Human-Centered Design; Service Sciences; Innovation Theories; Optimal Design

| Effects of a Mnemonic Technique on Subsequent Recall of Assigned and Self-generated Passwords | | BIBAK | Full-Text | 693-701 | |
| Deborah Nelson; Kim-Phuong L. Vu | |||
| Participants were trained on how to use a mnemonic strategy for memorizing
assigned passwords or for generating new passwords. Memory for these passwords
was examined at short and long recall delays. There was a significant
interaction between type of password and recall delay for both the amount of
time and number of attempts needed for participants to accurately recall their
passwords. Participants trained in how to use the mnemonic technique to
generate their own passwords were able to recall them more quickly and
accurately than participants who were trained in how to use the mnemonic
technique to memorize their assigned passwords. The impact of self-generated
passwords on memory was discussed as well as the relative value of the mnemonic
training strategy. Areas of future research were identified that may lead to
the development of mnemonic training strategies to better enable users to
recall their passwords. Keywords: memory training programs; mnemonics; retrieval strategies; passwords;

| Control of Personal Tempo to Support Individual Action and Cognition | | BIBAK | Full-Text | 702-708 | |
| Naoya Nobutani; Yoshio Nakatani | |||
| We live in our own rhythms in daily lives. Human life is closely related to
rhythm as the words "talk rhythm," "getting into the rhythm" and the
"Biorhythm" show. The rhythm is important for us to live in order and
cheerfully. Each person has his/her own action rhythm called the "Personal
Tempo." It is the basic rhythm observed in person's voluntary actions, such as
tapping on a table. Psychology has been studying this phenomenon for long
years. By measuring the personal tempo, person's psychological condition can be
inferred in all situations because personal tempo changes within a certain
width according to person's psychological condition, while it basically shows
homeostasis. Most studies have focused on relation between personal tempo and
physiological measures, such as cardiac rate, but not on control of cognitions
and actions by controlling personal tempo. In this paper, a control method of
individual action by controlling the personal tempo is proposed. Drum beat
pattern is used to control the personal tempo. We show the effectiveness of
this method by applying this to cooking, especially chopping by a knife. Keywords: personal tempo; rhythm; action control; sound rhythm | |||
| The Effects of Practice and Speed Stress with Different Stimulus-Response Mappings | | BIBAK | Full-Text | 709-717 | |
| Kim-Phuong L. Vu; Audrey Rabas; Richard Roberson | |||
| Stimulus-response (S-R) compatibility refers to better performance with
compatible over incompatible S-R mappings. We investigated how a stressor in
the form of a time constraint influences performance in choice-reaction tasks
with S-R mappings that varied in degree of compatibility. A 600-ms response
deadline did increase participants' stress levels as indicated in subject
workload reports. Furthermore, the time constraint decreased reaction time and
increased error rate more for incompatible (mirror-opposite, mixed and random)
mappings compared to compatible mappings. Participants who learned to respond
with the incompatible mappings reverted to the more natural, corresponding
responses when stressed. However, the effect of the time constraint was reduced
when the incompatible mapping was systematic compared to when it was random.
Thus, there are benefits of applying systematic rules when designing products
for a user population. Keywords: Stimulus-response compatibility; display-control compatibility; stress;

| Application of Population Stereotypes to Computerized Tasks | | BIBAK | Full-Text | 718-725 | |
| Jeff Wiebe; Kim-Phuong L. Vu | |||
| Control-display configurations are the primary means by which people
interact with machines and equipment. Regardless of the level of complexity,
these configurations should be designed in accordance with the preferred
responses of the user population to achieve a successful interaction. These
responses are known as population stereotypes. This study examined whether
mouse-click response tendencies adhere to Warrick's, scale-side, and
clockwise-to-increase principles. More stereotype consistent responses were
obtained for dial-turn questions than for mouse-click questions, implying that
the movement of the control may be an important factor when predicting users'
responses based on these three principles. These findings indicate that care
must be taken when applying population stereotypes to programs that use
mouse-click responses. Keywords: human factors; population stereotypes; Warrick's principle; scale-side
principle; clockwise-to-increase principle; control-display configurations | |||
| Designing Transportation Services Based on HCD | | BIBAK | Full-Text | 726-735 | |
| Kiko Yamada-Kawai; Naotake Hirasawa; Shinya Ogata; Shou Ohtsu | |||
| A "Social System" enabled by ICT, such as Intelligent Transportation System
affects society itself as well as users' behavior. When designing these
systems, an approach of having users or citizens in the center of the system is
most crucial to derive planned use of the system. In this study, examples of
social systems in the fields of transportation and e-government are first
reviewed to reveal the history and issues, and then defined the definition of a
"social system." A case example is made on ITS in regard with obtaining higher
quality in use by employing Human-centered Design. The necessity of broadening
conventional HCD methodologies is further discussed. Keywords: Human-centered Design; social system; Intelligent Transportation System;
