Visualisation Methods and Techniques

Visualization Tool for Finding of Researcher Relations BIBAFull-Text 3-9
  Takafumi Aoki; Yoshikazu Sasamoto; Keisuke Makita; Shingo Otsuka
It is possible to collect knowledge of interest research field effectively if we can look for the key person of the field. In addition, when the people who belong to administrations and companies want to undertake information gathering to the person of a particular field, it is convenient if the key person of the field is found easily. In this paper, we propose the visualization tool for finding of researcher relations using the conference programs.
Selection Classification for Interaction with Immersive Volumetric Visualizations BIBAKFull-Text 10-21
  Amy Banic
Visualization enables scientists to transform data in its raw form to a visual form that will facilitate discoveries and insights. Although there are advantages for displaying inherently 3-dimensional (3D) data in immersive environments, those advantages are hampered by the challenges involved in selecting volumes of that data for exploration or analysis. Selection involves the user identifying a set of points for a specific task. This paper preliminary data collection on natural user actions for volume selection. This paper also presents a research agenda outlining an extension for volume selection classification, as well as challenges, for designing components for a direct selection of volumes of data points.

Analyzing HCI Issues in Data Clustering Tools BIBAKFull-Text 22-33
  Clodis Boscarioli; José Viterbo; Mateus Felipe Teixeira; Victor Hugo Röhsig
Due to the rapid growth in the volume of data stored in organizational databases and the human limitations in analyzing and interpreting data, appropriate techniques are necessary to allow the identification of a large amount of information and knowledge in such databases. In this context, several techniques and tools have been proposed for enabling the end user to interpret his dataset. In this work we discuss the ways of interacting with cluster analysis tools, taking into account both the clustering and the interpretation stages. We investigate how usability and user experience aspects of such tools can improve the understanding of the discovered knowledge. Moreover, we evaluate the role of visualization methods in the comprehension of groups formed in cluster analysis using Knime, Orange Canvas, RapidMiner Studio and Weka data mining tools.

A Post-simulation Assessment Tool for Training of Air Traffic Controllers BIBAKFull-Text 34-43
  Aslak Wegner Eide; Stian Støer Ødegård; Amela Karahasanovic
This paper proposes a post-simulation assessment tool that aims to improve the training of air traffic controllers (ATCOs) by visualizing their performance. The tool helps the controllers to identify bottlenecks in flight traffic and find alternative solutions that might improve traffic throughput. The usefulness of the tool was evaluated in a study involving benchmark tests and interviews with five experienced ATCOs. The results from the study indicate that the tool can help ATCO students to (1) identify irregularities in their work, (2) find possible underlying causes of these irregularities, and (3) find alternative solutions preventing these irregularities. Visual feedback consisting of workflow graphs and radar replays might generate valuable insights that enable self and peer assessment during ATCO training. Our results might be interesting both for the practitioners working with ATCO training and for researcher investigating the effects of visualization in education.

Label Embedded Treemapping: A Label Overlap Prevention Technique for Zoomable Treemaps and a User Interaction Technique BIBAKFull-Text 44-53
  KwangHyuk Kim; JungHyun Han
Data navigation of a treemap -- a widely used tool for visualizing tree data -- becomes more difficult as the amount of data increases. To solve this problem, treemap techniques using zoomable user interface (ZUI) methods -- the most typical of which is the zoomable treemap (ZTM) -- have been proposed. However, ZTMs can incur face text overlapping issues between examined nodes. In order to increase ZTM readability, we propose a label embedded tree map technique that prevents label overlapping and a direct node selection method for the highlighting of focused parent nodes. The proposed tree map technique resolves the ZTM label conflict and the direct node selection method can efficiently improve data navigation.

An Interactive Approach to Constraint-Based Visualizations BIBAKFull-Text 54-63
  Wendy Lucas
This paper describes an approach that puts even inexperienced users in charge of force-directed layouts. The visual interface to a powerful but relatively easy to use visualization grammar has been augmented with sliders for controlling the strength of constraints applied to visual objects. Users can change the balance of power between constraints while an animated visualization is running, turn off the constraints affecting the layout, or return a layout to its pre-constraint-solving specification. An initial empirical evaluation supported the usefulness of this interactive design intervention for providing user control over force-directed layouts. This approach is a step towards addressing the lack of tools with which less sophisticated users can design customized visualizations that best meet their needs.

User Similarity and Deviation Analysis for Adaptive Visualizations BIBAFull-Text 64-75
  Kawa Nazemi; Wilhelm Retz; Jörn Kohlhammer; Arjan Kuijper
Adaptive visualizations support users in information acquisition and exploration and therewith in human access of data. Their adaptation effect is often based on approaches that require the training by an expert. Further the effects often aims to support just the individual aptitudes. This paper introduces an approach for modeling a canonical user that makes the predefined training-files dispensable and enables an adaptation of visualizations for the majority of users. With the introduced user deviation algorithm, the behavior of individuals can be compared to the average user behavior represented in the canonical user model to identify behavioral anomalies. The further introduced similarity measurements allow to cluster similar deviated behavioral patterns as groups and provide them effective visual adaptations.
Evaluating the Dot-Based Contingency Wheel: Results from a Usability and Utility Study BIBAKFull-Text 76-86
  Margit Pohl; Florian Scholz; Simone Kriglstein; Bilal Alsallakh; Silvia Miksch
The Dot-Based Contingency Wheel is an interactive visual-analytics method designed to discover and analyze positive associations in an asymmetrically large n×m contingency table. Such tables summarize the relation between two categorical variables and arise in both scientific and business domains. This paper presents the results of a pilot evaluation study based on interviews conducted with ten users to assess both the conceptual design as well as the usability and utility of the Dot-Based Contingency Wheel. The results illustrate that the Wheel as a metaphor has some advantages, especially its interactive features and ability to provide an overview of large tables. On the other hand, we found major issues with this metaphor, especially how it represents the relations between the variables. Based on these results, the metaphor was redesigned as Contingency Wheel++, which uses simplified and more familiar visual representations to tackle the major issues we identified.

Prediction or Guess? Decide by Looking at Two Images Generated by a "MATLAB MySQL" Algorithm BIBAKFull-Text 87-97
  Carlos Rodríguez
In the field of data mining, predictive modeling refers to the usage of a statistical model built on a training data set in order to make predictions about new prospects contained in the scoring data set. A model should not be used to predict when it encounters unseen data in the scoring set because such predictions would be a guess or a speculation. This paper proposes an algorithm that will produce two simple images and a "level of guessing" (LOG) pie chart. These images will tell the analyst whether or not it is appropriate to use a statistical predictive model to make predictions on a particular scoring set. The proposed algorithm will offer a solution to the scoring adequacy problem based on subsets of the original data. The algorithm will be implemented with a user interface built with MATLAB code, which acts on MySQL databases that contain the data.

A Step Beyond Visualization: Applying User Interface Techniques to Improve Satellite Data Interaction BIBAFull-Text 98-107
  Tatiana A. Tavares; Humberto A. Barbosa
In this paper, we discuss the potential of applying interaction techniques to manipulate GEO satellite data. The proposed study shows the potential of Meteosat Second Generation (MSG) data in refining the mesoscale analyses incorporating HCI techniques, as natural interaction resources. Moreover the software tools used to develop the interaction layer, is based on open source codes. Open source codes are also used for geolocation and geographical information systems, written for the transformation of MSG data into input files. This feature have demonstrated a great flexibility and ease of use. The study open up an avenue for successive validation and refinement of the analyses together with their improved implementation for operational nowcasting and very short range forecasting applications.
An Intuitive Way to Describe Our World: A Microblog LBS Visualization System BIBAKFull-Text 108-119
  Jian-Min Wang; Lai Gan; Ri-Peng Zhang; Fang You
With the help of LBS provided by some social network service provider, people can obtain knowledge and perceive the world around them more conveniently. However, since the contradiction of a large number of POI nodes and the limited displaying space, finding a better layout algorithm to visualize the POI nodes is important for better user experience. This paper presents a new layout algorithm called Virtual Layout algorithm, which can solve the problem of the uneven POI nodes distribution and make a better presentation of the geospatial information. We also deployed a microblog LBS visualization system which consists of Virtual Layout algorithm, stylized map and location reference frame to verify the performance of the proposed algorithm.

Google Analytics Spatial Data Visualization: Thinking Outside of the Box BIBAKFull-Text 120-127
  Wanli Xing; Rui Guo; Ben Richardson; Thomas Kochtanek
This paper showcases a methodology to assist website managers in determining the influence of their websites in regard to a particular location. This is achieved through enhancing Google Analytics by supplementing it with outside data sources. Though GIS software namely ArcGIS, the approach allows for more comprehendible geospatial analysis while also presenting maps overlays that are easier to grasp than the tools currently offered by Google Analytics. The Truman Presidential Library website serves as a case study to explore the potentiality of this approach.

A Visualization Concept for Mobile Faceted Search BIBAKFull-Text 128-136
  Bianca Zimmer; Romina Kühn; Thomas Schlegel
Nowadays, people are increasingly using their mobile devices to find different kinds of information, for example, about products, trips or latest news. Therefore, mobile devices such as smartphones and tablets have become a constant companion for many users to have access to information at any time and any place. The large amount of data and information that is provided to the user by mobile devices differs in its feature set and visual representation. To ensure the success of an app and to keep the user from an information overload by presenting too much information, a wise preparation and visualization of the data is necessary. Faceted search provides an opportunity to focus on specific information by filtering. In this paper we present a general visualization concept for faceted search on mobile devices, especially on smartphones.

Multimodal Interaction

Food Practice Shooter: A Serious Game with a Real-World Interface for Nutrition and Dietary Education BIBAKFull-Text 139-147
  Yuichi Bannai; Takayuki Kosaka; Naomi Aiba
Along with the recent increase in the diversity of food options especially soft foods, problems of unbalanced eaters and insufficient chewing have gained notice. Games, which many children are enthusiastic about, may provide an opportunity to encourage children to voluntarily consume disliked foods. In this paper, we describe Food Practice Shooter, a serious game with a physical interface and public gameplay that presents food consumption as a win condition. This game can be used for dietary education to induce balanced eating behavior and sufficient chewing in children.

A New Computational Method for Single-Trial-EEG-Based BCI BIBAKFull-Text 148-156
  Shin'ichi Fukuzumi; Hiromi Yamaguchi; Kazufumi Tanaka; Toshimasa Yamazaki; Takahiro Yamanoi; Ken-ichi Kamijo
In this paper, the categorization of single-trial EEG data recorded during the MI-related task, as another data reduction, will be attempted, because the categorical data would require less storage and computational time than continuous one. The categorization will be realized by equivalent current dipole source localization (ECDL). To analyze this, we used EEG data and visually evoked related potentials (v-ERP) led by 32 electrodes. From the result of single-trial v-ERP, only 6 electrode v-ERPs have a remarkable reaction. Therefore, from the view point of business, it is found that the minimum number of electrodes have been seven.

Menu Hierarchy Generation Based on Syntactic Dependency Structures in Item Descriptions BIBAKFull-Text 157-166
  Yukio Horiguchi; Shinsu An; Tetsuo Sawaragi; Hiroaki Nakanishi
The present paper proposes a procedural design method which makes use of dependency structures underlying menu item descriptions in order to generate well-structured and easily-learned menu hierarchies. A dependency structure captures syntactic relations among conceptual units that constitute a natural language description of what function the corresponding menu item stands for. The proposed method classifies computerized system functions after dependency structure prototypes and then serializes variable elements to be specified in each function class after phrase structure analysis. Its clear and consistent policy provides generated menu systems with high communicability to users. The effectiveness of the method is empirically investigated.

Liquid Tangible User Interface: Using Liquid in TUI BIBAKFull-Text 167-176
  Masahiro Hotta; Makoto Oka; Hirohiko Mori
In recent years, tangible user interface (TUI) has been paid attention on as a next generation user interface. In most TUI researches, solid body is mainly used as manipulators to assist interaction and they do not focus on "liquid". So, I focused on liquid as real world object, and I proposed the interaction using liquid in TUI and confirmed advantages of the interaction. As the result, there are some advantages in the adjustment of a sensuous amount comparing solid TUI.

Three Key Challenges in ARM-COMS for Entrainment Effect Acceleration in Remote Communication BIBAKFull-Text 177-186
  Teruaki Ito; Tomio Watanabe
Remote communication systems, which are getting popular these days, allow us to enjoy the benefit of audio/video communication over the network. However, communication based on these systems is still not identical to face-to-face meetings. For example, open issues include lack of tele-presence, lack of entrainment in communication, etc. In order to tackle these issues, this study proposes an idea of remote individuals' connection through augmented tele-presence systems called ARM-COMS: ARm-supported eMbodied COmmunication Monitor System. ARM-COMS is composed of a tablet PC as an ICT (Information and Communication Technology) device and a desktop robotic arm which manipulates the tablet. Two types of modes, or intelligent tablet mode (IT-mode) and intelligent avatar mode (IA-mode), play a key role in ARM-COMS to implement the three functions; namely, autonomous positioning (AP), autonomous entrainment movement (AEM), and autonomous entrainment positioning (AEP). This paper proposes the basic concept of ARM-COMS to accelerate the entrainment effect in remote communication.

Two-Handed Interactive Menu: An Application of Asymmetric Bimanual Gestures and Depth Based Selection Techniques BIBAKFull-Text 187-198
  Hani Karam; Jiro Tanaka
In this paper, we propose a Two Handed Interactive Menu as an evaluation of asymmetric bimanual gestures. The menu is split into two parts, one for each hand. The actions are started with the non-dominant hand and continued with the dominant one. Handedness is taken into consideration, and a different interface is generated depending on the handedness. The results of our experiments show that two hands are more efficient than one; however the handedness itself did not affect the results in a significant way. We also introduce the Three Fingers Click, a selection mechanism that explores the possibility of using a depth-sensing camera to create a reliable clicking mechanism. Though difficult to maintain, our Three Fingers Clicking gesture is shown in the experiments to be reliable and efficient.
Keywords: bimanual gestures; depth-based click
Measurement of Hand Raising Actions to Support Students' Active Participation in Class BIBAKFull-Text 199-207
  Ryuji Kawabe; Michiya Yamamoto; Saizo Aoyagi; Tomio Watanabe
In recent years, teachers have been making an effort to improve positivity in students' participation in class. However, this can be difficult because active participation depends on both communication skills and classroom atmosphere. In this study, we focus on hand-raising motions, which play an important role in interaction. Based on this, we measured and analyzed hand-raising motions in various situations.

Study on Perception of Vibration Rhythms BIBAKFull-Text 208-216
  Daiji Kobayashi
In this study, we researched the way of designing the accessible vibration rhythms through experiments using the mouse-type tactile interface from the vibration perception and vibration memorability. Participants were twenty young individuals and fourteen older persons. First, the threshold of vibration duration and gaps between the duration were estimated statistically. As the result, some vibration rhythms were designed and evaluated the validity of the design factors. Further, the requirements for designing memorable vibration rhythms were considered. From the results, some requirements for designing perceivable and memorable vibration rhythms for older persons were found; however, it is required to clear the effect of vibration rhythm from the cognitive aspect through further research.

Effects of Type and Strength of Force Feedback on the Path of Movement in a Target Selection Task BIBAKFull-Text 217-225
  Martin T. Koltz; R. Conrad Rorie; Jose Robles; Kim-Phuong L. Vu; Panadda Marayong; Thomas Z. Strybel; Vernol Battiste
New flight deck technologies being developed under the proposed NextGen National Airspace System will require precise and efficient input from flight crews. The benefits of force feedback for these types of inputs in terms of a reduction in overall movement times have been shown in the past; however, an important component of input efficiency is the path taken by the cursor. The present study investigates the effects of multiple levels of two types of force feedback (gravitational and spring forces) on the path of movement for a target selection task. Mean square error from an ideal straight line path and cursor speeds in terms of the distance from the target were measured. Results suggest that increasing the gravitational force has an effect on path error at short distances and produces higher cursor speeds as the target is approached.

Effect of Haptic Perception on Remote Human-Pet Interaction BIBAKFull-Text 226-232
  Kazuyoshi Murata; Kensuke Usui; Yu Shibuya
Even when a pet owner is away from his/her pet, he/she often wants to feel closer to the pet. The purpose of this study is to provide a means for the pet owner to feel the presence of his/her pet even when away from it; this is achieved by exchange of haptic feedback. In this paper, we describe such a remote haptic interaction system that consists of haptic devices for remote haptic communication; we also utilize tablets for video chat. A pet owner and his/her pet can feel closer to one another via haptic responses generated by corresponding haptic device. Two experimental evaluations were conducted to compare interactions between a pet owner and his/her pet using our system with another interactions achieved only via video chat. Results showed that these remote haptic interactions increased the pet owner's feeling of communicating with his/her pet. In general, pet owners reported feeling closer to their pet by using our system.

Development of High-Speed Thermal Display Using Water Flow BIBAKFull-Text 233-240
  Masamichi Sakaguchi; Kazuki Imai; Kyohei Hayakawa
A temperature sense is one kind of tactile sense. It doesn't have high spatial resolution and time resolution. But a change in the sudden temperature is also used for sense of danger. That has a high possibility that it can be applied to information display. In this study, water with the high specific heat is used as heat carrier. High-speed thermal display systems are developed by changing warm water and cold water in temperature exposition. In this paper, we explain the characteristics of the temperature measurement system and also describe thermal display system using the rectangular flow channel. Then we developed a water circulation type thermal display system.

Evoking Emotions in a Story Using Tactile Sensations as Pseudo-body Responses with Contextual Cues BIBAKFull-Text 241-250
  Sho Sakurai; Toki Katsumura; Takuji Narumi; Tomohiro Tanikawa; Michitaka Hirose
In this paper, we propose a method to evoke multiple emotions by presenting a combination of some tactile sensations in the contextual situation of others' experience. Recent psychological researchers have argued that some sort of emotion evokes through recognizing not only change in real body reactions but also feedback of sensory stimuli that resemble the change in somebody reaction. On the other hand, evoked emotion varies depending on a context of their experience, even if the change in bodily response is same. Based on the knowledge, we hypothesize that providing a variety of pseudo-physiological responses with a controlled context can evoke various emotions, even when the pseudo-physiological responses are the same. In order to test this hypothesis, we made a system named "Comix: beyond," which evokes seven types of emotion using three tactile sensations as pseudo physiological responses associated with the context of the story of the comic.

Enhancement of Accuracy of Hand Shape Recognition Using Color Calibration by Clustering Scheme and Majority Voting Method BIBAKFull-Text 251-260
  Takahiro Sugaya; Hiromitsu Nishimura; Hiroshi Tanaka
This paper presents methods of enhancing the recognition accuracy of hand shapes in a scheme which is proposed by the authors as being easy to memorize and which can represent much information. To ensure suitability for practical use, the recognition performance must be maintained even when there are changes in the illumination environment. First, a color calibration process using a k-means clustering scheme is introduced as a way of ensuring high performance in color detection. In the proposed method the thresholds for hue values are decided before the recognition process, as a color calibration scheme. The second method of enhancing accuracy involves making a majority decision. Many image frames are obtained from one hand shape before the transition to the next shape. The frames in this hand shape formation time span are used for shape recognition by majority voting based on the recognition results from each frame. It has been verified by carrying out experiments under different illumination conditions that the proposed technique can raise the recognition performance.

Analyzing Structure of Multiparty Interaction: Group Size Effect in Story-Retelling Task BIBAKFull-Text 261-270
  Noriko Suzuki; Mamiko Sakata; Noriko Ito
This paper examines the differences in verbal and nonverbal behaviors between different group sizes, specifically two-party and three-party interactions. An experiment was conducted using a story-retelling task. The interaction data were recorded with a video camera. Speech, gaze, and gesture data in both group sizes were analyzed. The results suggest that participants in three-party interaction change speakers more frequently by turning their gaze to each other than do those in two-party interaction.

Information Coding by Means of Adaptive Controlling Torques BIBAKFull-Text 271-280
  Johann Winterholler; Julian Böhle; Krzysztof Chmara; Thomas Maier
The investigated approach shows that the currently rarely used haptic perception channel can systematically be applied for information transfer. The encoding of information by variable controlling torques and the haptic transmission of information to the user via a central control element can lead to a reduction of visual distraction and cognitive stress in difficult tasks. Furthermore, this approach allows innovative interfaces so that the usability of products can be improved and the operational safety can be increased.

Basic Research on the Factors Influencing Perception of Texture from Images BIBAKFull-Text 281-288
  Kimihiro Yamanaka; Kazuki Nagamura
We conduct a subjective evaluation experiment by using the semantic differential method to examine the relation between the shape, color and size of an object in an image and the emergence of texture perception. The experiment consists of an evaluation survey on the perceived texture of a visual stimulus displayed on a monitor. The stimulus is a simple shape (ball, cylinder or box) created using a computer graphics application; ach shape appears in one of three colors (red, blue or green) and at one of two sizes (large or small) for a total of 18 distinct stimuli. The factors were extracted from the data by principal factor analysis, and the factor loadings were calculated by promax rotation. Furthermore, the relations between each factor and texture perception were examined through Hayashi's first quantification method, a kind of regression analysis.
   The results indicated relations between each item and the sensations of smoothness, hardness and moistness, which are considered to be representative of texture perception.
Keywords: material perception "Shitsukan"; semantic differential method; Hayashi's first quantification method

Knowledge Management

KADEN Project -- Towards the Construction of Model for Sharing Cognition in Manufacturing -- BIBAKFull-Text 291-297
  Takeo Ainoya
One of the methods which create new ideas to secure the quality of the relationship of the product and human is to find the many participants in manufacturing and to integrate the knowledge between different fields. Therefore, in order to perform the manufacturing integrated, we aim to construct a cognitive sharing model for sharing the recognition of each other, and take advantage of the expertise of each using the shared recognition. In this paper, we propose a process that worked as project-based educational activities.

Enhancing Interdisciplinary Cooperation by Social Platforms BIBAKFull-Text 298-309
  André Calero Valdez; Anne Kathrin Schaar; Martina Ziefle; Andreas Holzinger
In large-scale research projects active management of the cooperation process is necessary, e.g. to ensure systematic transfer of knowledge, alignment of research goals, or appropriate dissemination of research efforts. In a large scale research-cluster at the RWTH Aachen University a cybernetic management approach is applied. As a planned measure, publishing efforts (i.e. bibliometric data) will be visualized on a social software platform accessible by researchers and the steering committee. But do researchers agree with the chosen style of visualization of their publications? As part of a user centered design, this paper presents the results of an interview study with researchers (n=22) addressing the usefulness and applicability of this approach. As central findings arguments for using the publication visualization are identified such as enabling retrospective analysis, acquiring new information about the team, improvement in dissemination planning, but at the same time contrasted by arguments against this approach, such as missing information, a possibly negative influence on workflow of researchers, and the bad legibility of the visualization. Additionally requirements and suggested improvements are presented.

SPARQL Query Writing with Recommendations Based on Datasets BIBAKFull-Text 310-319
  Gergo Gombos; Attila Kiss
When we write a SPARQL query, we need to know the structure of the dataset. In the relation databases the tables have a scheme, but the semantic data do not have. Autocompletion function exists in SQL environment, but it does not exist in SPARQL environment. We made a system that can help to write SPARQL query. The system has two features. The first is the prefix recommend. We can write shorter queries if we use prefixes because we do not need to write the long IRIs. The second feature is the predicate-based recommendation based on the type of the variable. If a variable is in the query and it has a type condition, then our system recommends further predicates of this type. Our system needs information about the dataset for the recommendation. We can get these information with simple SPARQL queries. The queries run on a federated system. It is useful because the user does not need any information about the endpoints.

Personal Information Management Competences: A Case Study of Future College Students BIBAKFull-Text 320-331
  Jerry Jacques; Pierre Fastrez
The research project presented in this paper aims at modeling the media literacy competences required to organize and manage collections of information in the form of personal and shared digital environments. In-depth in situ interviews were conducted with future college students (N=11). During the interviews, the informants gave a guided tour of their personal space of information, and demonstrated how they used different digital tools to organize it. We identify three dimensions of personal information management (PIM) competence, based on the analysis of the way our informants describe their PIM practices by referring to and articulating (1) the constraints and affordances of the tools and devices they use, (2) the activities these tools and devices support, (3) the costs and benefits of these practices for these activities, and (4) their tastes and preferences towards them.

A Map-Based Web Search Interface Using Point of Interest Aggregation BIBAKFull-Text 342-351
  Kwangsoon Jung; Sangchul Ahn; Heedong Ko
With advent of a mobile computing, the pattern of information search has been changed. Search queries through mobile devices increase; 30% of Google's organic search queries come from mobile devices, and local search, which seeks information with geospatial constraints, also increases. As of 2013 local search on mobile phones continues to grow up to 60% since 2010. However, a large number of web documents cannot be exposed to local search even though they refer to a point of interest (POI) just because they are not explicitly geo-tagged. We are interested in connecting typical web documents to spatial search based on POIs by geotagging web documents. In this paper, we present a map-based web search system that serves geospatial search queries for non-geotagged documents. The proposed system provides with fine-grained local search for typical web pages mentioning several POIs and supports semantic search in accordance with their spatial relation of inclusion.

Quality Function Deployment Using Improved Interpretive Structural Modeling BIBAKFull-Text 352-363
  Takeo Kato; Yoshiyuki Matsuoka
Due to the product diversification and complication, sharing the product information between the product development members has been important in the product development process. Quality Function Deployment (QFD) is one of the effective methods to share the information of the product using the quality matrices that describes the relationship between design elements needed to be considered. This paper improves QFD by applying the Interpretive structural modeling (ISM). The ISM visually expresses the complex relationship between design elements by using matrix operation. This paper also improves the ISM in order to evaluate not only the relationships between the same type of design elements but also that between in different type. The proposed QFD is applied to a disc brake design problem, and their applicability is confirmed.

Finding Division Points for Time-Series Corpus Based on Topic Changes BIBAKFull-Text 364-372
  Hiroshi Kobayashi; Ryosuke Saga
This paper describes the discovery method of finding proper points for dividing a corpus with time series information for extracting local and frequent keywords. Local and frequent keywords express a corpus with time series information and are useful for comprehending it. To extract keywords from the corpus, the previous works proposed corpus separating method. However, this method divides the corpus at equal intervals so that it cannot take into account the change of topic. To consider the change of topics and divide the corpus based on it, we utilize the idea of topic model and the topic extracted by Latent Dirichlet Allocation (LDA). In the experiment using newspaper articles during five years topics, we confirm that the topics of each document change as time passed by using the output from LDA and the point which is available on dividing the corpus by the change of topics notably is observable.

Computerized Information Standards Enabling Innovation in Public Procurement of Buildings BIBAKFull-Text 373-383
  Christian Koch; Kim Jacobsen
Computerized and standardized information enables innovation in processes, products and services. Where early research on the impact of standards tended to focus on barriers, more recent research advocates standardisation as enabler of innovation albeit in a stakeholder-oriented, flexible manner. This paper asks whether computerized information standards enable or constrain innovation in public procurement of buildings. In architectural and engineering design of public buildings handling of information involves interoperability problems that hamper innovation. Moreover the project based product development tends be done in constellations of firms in interorganisational contracting, which do not provide stability or room for innovation. A large hospital project was investigated through interviews, documents and observations. The effects of implementing building information standards are both inter- and intraorganisational. The building client claims to have saved money, through better structured building component data that gave considerable positive effects during tendering. The IT-suppliers develop IT-tools, preparing for new markets.

Improving Academic Listening Skills of Second Language by Building up Strategy Object Mashups BIBAKFull-Text 384-395
  Hangyu Li; Shinobu Hasegawa
Most foreign students studying abroad lack of academic listening ability which is considered to be very important for their academic life. Among the four language activities (Reading, Listening, Speaking and Writing), the listening comprehension ability is perceived as the most difficult to improve. Therefore, the purpose of this research is to support the training of academic listening ability for the students pursuing their academic success in a foreign educational institute. Firstly, this research identifies and organizes listening strategies proved to be effective in academic listening through past researches and modulates them as sequential learning processes referred as strategy models. And then based on the various strategy models, the components of supporting functions serving as strategy objects are to be designed and developed. By putting various strategy objects together, the learners are able to build up personal learning environments (Strategy Object Mashups) based on their characteristics and conditions. At the same time, a feedback agent is to be implemented for recommending proper object mashups to the learners according to their learning situations.

Information Search and Retrieval

Towards Semantic Image Retrieval Using Multimodal Fusion with Association Rules Mining BIBAKFull-Text 407-418
  Raniah A. Alghamdi; Mounira Taileb
This paper proposes a semantic retrieving method for an image retrieval system that employs the fusion of the textual and visual information of the image dataset which is a recent trend in image retrieval researches. It combines two different data mining techniques to retrieve semantically related images: clustering and association rule mining algorithm. At the offline phase of the method, the association rules are discovered between the text semantic clusters and the visual clusters to use it later in the online phase. To evaluate the proposed system, the experiment was conducted on more than 54,500 images of ImageCLEF 2011 Wikipedia collection. The proposed retrieval system was compared to an online system called MMRetrieval and to the proposed system but without using association rules. The obtained results show that our proposed method achieved the best precision and mean average precision.

Personalized Information Retrieval: Application to Virtual Communities BIBAKFull-Text 431-438
  Azza Harbaoui; Sahbi Sidhom; Malek Ghenima; Henda Ben Ghezala
Internet has become the largest library through the history of humanity. Having such a big library made the search process more complicated. In fact, traditional search engines answer users by sending back the same results to different users having expressed different information needs and different preferences. A significant part of difficulties [1],[4] is due to vocabulary problems (polysemy, synonymy...). Such problems trigger a strong need for personalizing the search results based on user preferences. The goal of personalized information [11] is to generate meaningful results to a collection of information users that may interest them using user's profile. This paper presents a personalized information retrieval approach based on user profile. User profile is built from the acquisition of explicit and implicit user data. The proposed approach also presents a semantic-based optimization method for user query. The system uses user profile to construct virtual communities. Moreover, it uses the user's navigation data to predict user's preferences in order to update virtual communities.

Content Based Image Retrieval Using Quantitative Semantic Features BIBAKFull-Text 439-448
  Anuja Khodaskar; Siddharth Ladhake
Retrieval of images based on low level visual features such as color, texture and shape have proven to have its own set of limitations under different conditions. In order to improve the effectiveness of content-based image retrieval systems, research direction has been shifted from designing sophisticated low-level feature extraction algorithms to reducing the 'semantic gap' between the visual features and the richness of human semantics. In this paper, the framework for Content-Based Image Retrieval system Fuzzy Logic approach is proposed to bridge the semantic gap between low level features and high-level semantic features with the aim to optimize the performance of CBIR systems.

Types of Document Search Tasks and Users' Cognitive Information Seeking Strategies BIBAKFull-Text 449-460
  Hee-Eun Lee; Wan Chul Yoon
For the researchers and learners, an unprecedented number of documents became available on the Internet and academic archives. Powerful search systems and sophisticated recommendation services are also available. Despite the IT assistance, finding the most useful information in daily knowledge works has become a cognitively demanding task more than ever due to the overwhelming number of documents. To improve the search systems with better human-computer cooperation, human information seeking strategies should be understood. This paper reports a study that identified the differences in the user search strategies with respect to two major search task types: open and purpose-driven exploring (OT) vs. closed and target-specified (CT) tasks. An observational experiment was conducted and the results were analyzed by mapping the user activities on a cognitive task-flow framework. The analysis comparing user activities in four search tasks revealed notable differences in their strategies to deal with the two task types. More frequent re-planning, especially goal reformulation, was observed for OT type tasks. The difference indicates that OT type tasks tended to trigger more knowledge-based behavior, while CT type tasks were performed relying more on rule-based behavior. These findings provide important insights for the design of search systems and user interfaces of knowledge-based systems.

Supporting Collaboration

Understanding Pragmatic Aspects with Social Values in Web-Mediated Collaborative Systems BIBAKFull-Text 471-482
  Rodrigo Bonacin; Julio Cesar Dos Reis; Heiko Hornung; Roberto Pereira; M. Cecília C. Baranauskas
Various aspects underlying collaborative discussions in web-mediated systems influence the interpretation of exchanged messages, which may prevent participants to better manage, retrieve and explore available content. In this article, we argue that pragmatics and social values play a key role in this scenario, influencing each other. We propose to articulate aspects of pragmatics and values, and conduct four empirical analyses in a real-world case study. We ground our analyses on concepts and methods of Organizational Semiotics. The paper presents an analysis of participants' interaction, a communication analysis based on a framework of illocutions, and a discussion on the shared social values. Our results indicate possible interdependencies between social values and categories of illocutions.

Our study introduces a mobile navigation system enabling a sound input interface. To realize high-performance environmental sound recognition system using Android devices, we organized a database of environmental sounds collected in our daily lives. Crowdsourcing is a useful approach for organizing a database based on collaborative works of people. We recruited trial users to test our system via a web-based crowdsourcing service provider in Japan. However, we found that improvement of the system is important for maintaining the motivation of users in order to continue the collection of sounds. We believe that the improved user interface (UI) design introduced to facilitate the annotation task. This paper describes an overview of our system, focusing on a method for utilizing the crowdsourcing approach using Android devices, and its UI design. We developed a touch panel UI for the annotation task by selecting an appropriate class of a sound source.

MulDiRoH: An Evaluation of Facial Direction Expression in Teleconferencing on a Multi-view Display System BIBAKFull-Text 525-535
  Shiro Ozawa; Satoshi Mieda; Munekazu Date; Hideaki Takada; Akira Kojima
We have developed a teleconference system called MulDiRoH (Multi-Directional Representation of Humans). It features the use of a QDA screen, one of the newest multi-view display techniques. A principal benefit of multi-view displays is they can show views of a remote participant from the direction in which the participant's face is pointing. This enables other participants to directly see the face of a remote participant who is actually looking away from them. However, all multi-view display systems share a common problem in that users who stand outside of the center area cannot observe geometrically correct images. To address this problem, we propose the use of the perspective transform method. We also evaluate the conveying of a person's facial direction by a communication game for multiple users.

  Hidetsugu Suto; Patchanee Patitad; Namgyu Kang
In design field, collaboration is a crucial key method which leads to widen conceptual design idea. Collaboration helps us to share our knowledge together and concert idea in a design process. We also can share diverse viewpoints among collaborations. In this paper, a collaboration support system which based on extended ADT model, TTS method ADT is proposed. ADT model is a representation model for conceptual design. It is used for grasping artifacts as a communication medium between designers and users. The process of observing, sharing and creating design plans are represented through the extended ADT model. During an observation process, three influential factors: physical factor, emotional factor and cultural factor are observed with diverse viewpoints. Each process is visualized and shared by using TTS method by using visual information such as idea sketch, note and photo. By using this tool, designers in a team can visualize their idea, share it with others, and create novel design plan which based on multi-cultural background. An example of design process with TTS method is given in order to show the efficiency of proposed method.

A Study of the Factors Affecting Product Values and Preferences -- Using Vacuum Cleaner as an Example BIBAKFull-Text 561-571
  Wen-chih Chang; Hsiao-ying Tai
In an era of advanced technology and information, products change rapidly and manufacturing techniques continuously improve, thus, consumers have more options when purchasing goods and competition among brands becomes severe. In the market, there are various brands of vacuum cleaners. It is important for the products of different brands with similar functions to stand out in order to attract consumers. If they can have attractive appearance and provide consumers with visual differences, they will trigger consumers' purchase desire. This study treats vacuum cleaners as examples in order to determine the correlation between the actual prices of goods in the market and values and preferences of goods to the participants, as well as the relation between values and preferences according to questionnaire survey. Through in-depth interview, the participants suggested the factors of rising and falling ranks of values and preferences, in comparison to actual prices. Research findings will serve as reference for the development of product design. Several important conclusions are found as reference for the industry and designers.

The Influence of the Designer's Expertise on Emotional Responses BIBAKFull-Text 572-582
  Hui Yueh Hsieh
This study examined whether people who had received design training responded differently to non-verbal risk communication materials. More specifically, it examined whether the level of expertise affected the emotions. The study measured emotional responses to visual stimuli in 324 Taiwanese participants (users, novice designers, intermediate designers and expert designers), using a Chinese translation of the abbreviated PAD Emotion Scales. Significant main effects of varying levels of expertise were found on all three dimensions of the PAD. Design expertise was inversely related to pleasure; the more design experience, the more unpleasant they rated the stimuli. Design expertise was positively related to arousal; the more design experience, the more arousing they perceived the stimuli. Design expertise was negatively related to dominance; the more design experience, the more 'submissive' they rated the stimuli.

  Yinghsiu Huang; Jian-You Li
Today's computing capacity, however, has been far more than two decades ago, which only could convert 2D sketches to 3D models. Therefore, how to utilize the ability of generating 3D derivative model from natural inspirations for forming product shapes is the main problem of this research. In order to investigate the problem of this research, therefore, the objectives of the research can be divided into two stages: 1. to analyze principles from natural objects, components, or/and structures; 2. to simulate and create innovative shapes by applying computer 3D software, such as Rhino and Grasshopper, based on natural principles for developing new product designs. At the end of this study, with computer 3D derivative abilities and with the technologies of 3D-printing, the results of this paper will propose some generative product forms by simulating and inspiriting from natural creatures.

User Experience Evaluation Framework for Human-Centered Design BIBAKFull-Text 602-612
  Hiroyuki Miki
Recently, the word "User Experience (UX)" has been often used in usability-related areas such as web design and system design. Although it was defined in ISO 9241-210 and its importance has been growing, details of the notion and results of introduction of it have not been well clarified yet. In the previous paper, a UX evaluation framework based on ISO 9241-11 and ACSI (American Customer Satisfaction Index) was proposed. Following the previous paper, this paper proposes an integrated new evaluation framework of usability and UX, explains its usage, and discusses its application.

Proposal of Evaluation Support System of Nursing-Care Service Components BIBAKFull-Text 613-620
  Takuichi Nishimura; Yasuhiro Miwa; Tomoka Nagao; Kentaro Watanabe; Ken Fukuda; Yoichi Motomura
We are trying to design employees' motivation and create technology to realize sustainable improvement in nursing-care service field. Components in nursing-care service such as how to care eating or how to help walking with a robot should be evaluated in order to improve the action and raise the service quality. But it is difficult to understand actions and results in the whole nursing-care service field because employees do not have enough time to record them and are not motivated to do so. Recording support mobile terminals cooperated with various sensors embedded in the facilities and employees will support visualize situation in such collaborative and face-to-face service field. Moreover motivation design for employees to record action and knowledge is crucial because human-sensor and human-computation ability is completely dependent on their proactivity. In this paper we propose evaluation support methodology of nursing-care service components with both direct effect and log-term effect of the action by participatory interaction design, which we proposed previously.

This study focused on shapes in accordance with the affordance theory. We would like to propose as a substitute for a mouse a new interface that enables humans to instinctively select functions. Instead of making the optimally shaped devices for each function of computers, the aim is to instinctively select functions with a minimum device. To this end, we verify what shape of devices would enable humans to imagine and select all the functions. The present study takes a close look at "how devices are held"; and we conduct experiments, focusing on musical instruments that are held in different manners.

We develop a support environment for software engineers that combine human centered design (HCD) policy with system development process to improve usability. We verified this support environment experimentally, and we observed that software engineers could not carry out works corresponding to "Analyze context of use", which is one of HCD activities and is usually done easily by usability engineers. Through this verification process, we found that there is some difficult task about HCD activities for software engineers to carry out.

  Leonor Teixeira; Vasco Saavedra; Carlos Ferreira; João Simões; Beatriz Sousa Santos
Healthcare web-application development teams involve non-computer experts working (clinicians) on the requirements specification that is later processed by software engineers/analysts (conceptual model) and coded by software programmers (software project). The management of this process, which involves different levels of abstraction and professionals with different backgrounds, is often complex. As such, mediators and facilitator's mechanisms for the requirements-gathering process and information transfer are needed. The main purpose of this work is to minimize the problems associated with this complex process, supporting the requirements engineering process of a healthcare web-application in a rapid prototyping model. The results proved that a rapid and functional prototyping model can improve the effectiveness of the requirement elicitation of any software development.
