Designing a Peer Reviewing Tool on Lecture Video with Handwritten Annotation BIBAKFull-Text 31-39
  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.

Usability Analyses of CRM Systems in Call Centers: The Data Mining Approach BIBAKFull-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.

Urgent Collaboration Service for Inclusive Use BIBAKFull-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.

Improvement of Member's Concentration during Discussion BIBAKFull-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.

Representation Method for Engineering Perspective BIBAKFull-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.

A Skill Transfer Method for Manual Machine Tool Operation Utilizing Cutting Sound BIBAFull-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 BIBAKFull-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.

Web Service Systems for Cooperative Work Support in Knowledge Creation Processes BIBAKFull-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.

Proactive Fault Detection Schema for Enterprise Information System Using Statistical Process Control BIBAKFull-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.

  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.

A Study on Effective Methods of Visual Inspection for Reused-Parts by Inspectors BIBAFull-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.

Exploring Employee Perspectives on Information Privacy and Security in the Mobile Environment BIBAKFull-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.

Organization Diagnosis Tools Based on Social Network Analysis BIBAFull-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 BIBAKFull-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.

Supporting Scenario-Based Product Design and Its Adapters: An Informal Framework for Scenario Creation and Use BIBAKFull-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.

How to Learn from Intelligent Products; The Structuring of Incoherent Field Feedback Data in Two Case Studies BIBAKFull-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.

Successful User Experience in an Agile Enterprise Environment BIBAKFull-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.

  Joseph H. Goldberg; Jonathan Helfman; John Beresniewicz
The difficult journey of introducing a new treemap visualization into enterprise software products is described, highlighting interactions among a research team, product teams, and management. Successful product integration ultimately required multiple iterations of prototyping, review, and redirection, as products were cancelled and modified. Several lessons learned are provided, including the need to build flexible and generic prototypes, cultivate champions, and be tenacious.
How Product Differentiation Affects Online Shopping BIBAKFull-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
Design and Evaluation of the Customized Product Color Combination Interface Based on Scenario Experience BIBAKFull-Text 263-270
  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.

Distribution of Human-Machine Interfaces in System-of-Systems Engineering BIBAKFull-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.

Reversing the Simon Effect with Prior Practice of Noncorresponding Location Words BIBAKFull-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.

Object-Oriented Interactive Processes in Decentralized Production Systems BIBAKFull-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.

A Retrospective and Prospective View of Information Technology Professionals' Use of Tools: Maturing the User Experience BIBAKFull-Text 306-315
  Candace Soderston
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.

Customer Boards as Vehicles of Change in Enterprise Software User Experience BIBAKFull-Text 316-322
  Anna M. Wichansky
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 different types of organizations. The board identified three major areas where it wanted to improve usability: consistency and design, integration and performance, and Web 2.0. Through various working groups, the board has developed tools for obtaining customer feedback on product usability, online seminars on technical topics, and outreach mechanisms to other customers. The board has effectively become Oracle's partner in ensuring product understanding and use, thus setting the stage for improved usability in the next-generation product.

Fashion Support from Clothes with Characteristics BIBAKFull-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.

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.

Facilitating Search through Visualized Results BIBAFull-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 BIBAKFull-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.

Exploiting Browsing History for Exploratory Search BIBAKFull-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.

A Proposal of Awareness Services for the Construction of Quality Community Knowledge Supported by the Knowledge Management System KnowCat BIBAKFull-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.

  Sarah Henderson; Ananth Srinivasan
Hierarchies have long been used as useful structuring mechanisms for organizing and managing documents. This study looks at the problem of personal digital document management in the context of knowledge workers. We study and document strategies that users employ to manage the complexity imposed by the volume and variety of personal digital documents. Exploratory research was conducted, analyzing the file systems of 73 knowledge workers using Microsoft Windows in a university setting. The empirical results of this are presented, and compared to a previous study that examined the file systems of 11 users.

Search Mathematical Formulas by Mathematical Formulas BIBAKFull-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.

Metadata-Based Reminder Classification in Reminiscence Engineering BIBAKFull-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.

The Roles of Profession and Gender in Some PIM Tasks BIBAKFull-Text 429-436
  Guangfeng Song; Chen Ling
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.

Efficient Text Classification Using Best Feature Selection and Combination of Methods BIBAFull-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 BIBAKFull-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.

A Proposal of EMG-Based Training Support System for Basketball Dribbling BIBAFull-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 BIBAFull-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 BIBAFull-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.
A Tangible Mixed Reality Interface for the AMI Automated Meeting Assistant BIBAKFull-Text 485-494
  Jochen Ehnes
In this paper we describe our approach to support ongoing meetings with an automated meeting assistant. We propose an alternative user interface for the AMIDA Content Linking Device. In order for the system to be less distractive and more collaborative than the original laptop screen based one, we developed a system that projects documents onto the table tops right in front of the meeting participants. This way they appear as if they were printed on paper, lying in front of the participants. We describe our setup as well as the user interface we built to handle and share these documents.

Design of Wearable Interface Considering Touch Communications BIBAKFull-Text 524-533
  Mariko Kato; Naoki Saiwaki
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.

f-MRI Study of Brain Activation in Tactile Feeling BIBAFull-Text 534-542
  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 BIBAFull-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.

  Changsun Lim; Seong-Jin Ahn; Jinwook Chung
This study deals with resolving the indefinite wait forced on normal resource reservations caused by the presence of priorities between normal resource reservations and advanced resource reservations. The algorithm we 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 specifications regarding the ratio of normal jobs to advanced reservations and guaranteeing advanced reservations, further studies will need to find ways to promote the efficiency of resource use.

Richbiff: E-Mail Message Notification with Richer Clues BIBAKFull-Text 570-578
  Mitsuru Minakuchi; Hisashi Miyamori
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.

A Study on Color Conversion for Color Deficient People to Identify Color BIBAFull-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 BIBAKFull-Text 601-610
  Jan Polowinski
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.

We proposed and developed a method to visualize the light path of a laser 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.

Virtual Convex Polygon Based Hole Boundary Detection and Time Delay Based Hole Detour Scheme in WSNs BIBAKFull-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.

An Interactive System Based on Semantic Graphs BIBAKFull-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.

Data Pattern for Allocating User Experience Meta-Data to User Experience Research Data BIBAKFull-Text 675-684
  Li Li; Hong Ji; Xuejiao Chen; Xiaowei Yuan
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.

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.

Effects of a Mnemonic Technique on Subsequent Recall of Assigned and Self-generated Passwords BIBAKFull-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.

Control of Personal Tempo to Support Individual Action and Cognition BIBAKFull-Text 702-708

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 BIBAKFull-Text 709-717

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.

Application of Population Stereotypes to Computerized Tasks BIBAKFull-Text 718-725

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.

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.
