[1] Translation method of contextual information into textual space of advertisements WWW 2014 posters / Tagami, Yukihiro / Hotta, Toru / Tanaka, Yusuke / Ono, Shingo / Tsukamoto, Koji / Tajima, Akira Companion Proceedings of the 2014 International Conference on the World Wide Web 2014-04-07 v.2 p.385-386

Summary: Contextual advertising has a key problem to determine how to select the ads that are relevant to the page content and/or the user information. We introduce a translation method that learns a mapping of contextual information to the textual features of ads by using past click data. This method is easy to implement and there is no need to modify an ordinary ad retrieval system because the contextual feature vector is simply transformed into a term vector with the learned matrix. We applied our approach with a real ad serving system and compared the online performance in A/B testing.

Summary: Understanding what cannot be seen is difficult. Physical behavior can be explained on the basis of physical theories even if the behavior cannot be observed. Explanation of what is physically happening in the real world would become easy, however, if annotations were superimposed on the real objects. Herein, the authors demonstrate how an understanding of a physical event can be facilitated by overlapping a real-world situation with a simulation that predicts a future state. This idea is demonstrated in a game application in which a player stacks blocks into a pile until it collapses. In general, it is easy to estimate whether a block on the edge of a table will fall or not. However, it is more difficult to predict whether a stack of many blocks will collapse, and in what manner the stack will collapse. Even though previous research has demonstrated that the problem of how two-dimensionally stacked blocks collapse can be reduced to solving a sequence of convex quadratic programs, algorithms for convex quadratic programs require massive computational resources. Hence, the authors developed a fast and new algorithm based on a linear program. The proposed algorithm realizes real-time simulation based on physics that superimposes predicted collapse. The block that is predicted to fall is superimposed on the real block with a lit background projection. The system was evaluated in an experiment, and superimposed augmented reality annotation was observed to be efficient. The system was also demonstrated in game contests and received positive feedback and comments.

[3] Relationship between Weight of Our Developed White Cane and Muscle Load on the Upper Limbs during Swinging Action of the Cane Universal Access and eInclusion / Doi, Kouki / Sugama, Atsushi / Nishimura, Takahiro / Seo, Akihiko / Ino, Shuichi / Nunokawa, Kiyohiko / Kosuge, Kazuhiko / Miyazaki, Akito / Sugiyama, Masaaki / Tanaka, Yoshihiro / Sawada, Mayumi / Kaneko, Ken / Ouchi, Susumu / Kanamori, Katsuhiro HCI International 2013: 15th International Conference on HCI: Posters' Extended Abstracts Part I 2013-07-21 v.6 p.231-235

Summary: The present study aimed to investigate the influence of the weight of white canes on upper limb load. Concretely, we conducted quantitative evaluations of the load on upper limb muscles during swinging action of the cane. The white canes used were a new type of white cane newly fabricated using aramid fibers, as well as a conventional type of white cane fabricated using carbon fibers. The results indicated that the newly developed cane reduced the load on the muscles by about 50% in comparison with the conventional type of cane. It became clear that it was possible to sustain the same posture even when used continuously over a long period of time.

Summary: Text data with spatio-temporal information are becoming common with the popularization of mobile phones with a GPS function and microblog services like Twitter. This study proposes a system supporting operators in a disaster prevention center who control an area in real-world. Our system has three functions: (i) automatic classification that classifies messages into a fixed category, (ii) clustering that aggregates similar messages and (iii) burst detection that detects an event in which messages are arising in high frequency. We asked 120 people to send text data with spatio-temporal information by cell phones in the Osaka Expo Memorial Park. We evaluated our system using the above data.

[6] Characteristics of Comfortable Sheet Switches on Control Panels of Electrical Appliances: Comparison Using Older and Younger Users Touch and Gesture Interfaces / Tanaka, Yasuhiro / Yamazaki, Yuka / Sakata, Masahiko / Nakanishi, Miwa HIMI 2011: Human Interface and the Management of Information, Symposium on Human Interface, Part I: Interacting with Information 2011-07-09 v.1 p.498-507

Keywords: Sheet switches; Electrical appliances; Elderly users; EMG; Comfort

Link to Digital Content at Springer

Summary: This study focuses on sheet switches, which are among the most common user interfaces in electrical appliances, and explores the comfort level required by elderly users. Touching a switch is a common action in our daily lives; however, little research has been performed on this action. In particular, we were unable to find any reports on the comfort elderly users experience upon touching a sheet switch. Thus, electrical-appliance designers have no well-prepared reference data when designing new products. As a consequence, elderly users experience discomfort when using new appliances. Our goal is to construct a guideline for designing comfortable sheet switches for elderly users. In this study, as the first step toward achieving this goal, we attempt to clarify the physical parameters of sheet-switch features that contribute toward ease of use and comfort.

Summary: Crowdsourcing is a new kind of organizational structure, one that is conducive to large amounts of short parallel work: thousands of individuals may work for several minutes on tasks, their outputs aggregated into a useful product or service. The dimensions of this new organizational form are described. Areas for future research are identified, focusing on open-ended tasks and the coordination structures that might foster collective creativity.

[8] TableCross: exuding a shared space into personal spaces to encourage its voluntary maintenance Works-in-progress / Nishimoto, Kazushi / Ikenoue, Akari / Shimizu, Koji / Tajima, Tomonori / Tanaka, Yuta / Baba, Yutaka / Wang, Xihong Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011-05-07 v.2 p.1423-1428

ACM Digital Library Link

Summary: A shared space should be cooperatively maintained by all users. However, due to social loafing, often nobody maintains it and its condition worsens. We propose exudation of a shared space. Part of a shared space is exuded into personal workspaces so that office workers are forced to subjectively experience the atmosphere of the shared space, even while they remain at their personal workspaces. This paper illustrates the first prototype named "TableCross," which reflects the degree of disorder of a table in a shared space to the desktop of each worker's PC. We also report some results of our pilot user study.

Summary: "Yaminabe YAMMY" is an interactive hot pot which provides a new way of cooking and sharing our memories and feelings. The feelings extracted from the contents of an email, associated with a photo will be interpreted into different "spices" which will then be sprinkled into the pot to alter the food's flavor.

[10] Enhancing the creativity of engineers by idea drawing Posters / Tanaka, Yoshifumi / Nakamura, Sumio / Takemata, Kazuya Proceedings of the 2009 Conference on Creativity and Cognition 2009-10-26 p.405-406

ACM Digital Library Link

Summary: Externalizing ideas in universally understandable diagrams may enhance communication and contribute to creative design. "Idea drawing" is a freehand drawing method developed to express accurately how an object looks based on elemental geometry and perspective. To examine whether idea drawing could contribute to the product design process, we held a course for engineers involved in manufacturing a product. An interview of a participant suggested that idea drawing may enhance communication between the engineers and thus help substantially in the creative design process.

Link to Digital Content at Springer

Summary: This paper focuses on a method to extract video browsing styles and reusing it. In video browsing process for knowledge work, users often develop their own browsing styles to explore the videos because the domain knowledge of contents is not enough, and then the users interact with videos according to their browsing style. The User Experience Reproducer enables users to browse new videos according to their own browsing style or other users' browsing styles. The preliminary user studies show that video browsing styles can be reused to other videos.

[12] Knowledge media and meme media architectures from the viewpoint of the phenotype-genotype mapping Keynote / Tanaka, Yuzuru ACM 24th International Conference on Design of Communication 2006-10-18 p.3-10

ACM Digital Library Link

Summary: Media to externalize some knowledge as knowledge resources for their sharing among people across time and space are generally defined as "knowledge media". Distribution of knowledge resources sooner or later forms a huge accumulation of knowledge shared by our society, which activates the reediting and redistribution of knowledge resources, and accelerates their memetic evolution. Meme media are knowledge media with reeding and redistribution functions. Each knowledge consists of its code and mode. The code defines the knowledge itself, while the mode defines the presentation details. For each externalized knowledge, we call its code its genotype, and its external representation including its mode its phenotype. Electronic information media have enabled us to edit multimedia documents through direct manipulation on a WYSIWYG editor. We may consider a similar editor to edit not only multimedia documents but also compound documents with embedded tools and services. The editing denotes the recombination of contents on some medium through direct manipulation. Each recombination of contents should be represented as a phenotype manipulation that defines the corresponding recombination of the genotype representation. In this paper, we will propose a new interpretation of knowledge media and meme media. This will clarify the essential mechanism from the view point of the "phenotype-genotype mapping". We will use this interpretation to review the meme media architecture, and to reformulate how the meme-media architecture can be applied to the Web to make it work as a meme pool.

[13] Integration of a 2D legacy GIS, legacy simulations, and legacy databases into a 3D geographic simulation Best practices / Ohigashi, Makoto / Guo, Zhen-Sheng / Tanaka, Yuzuru ACM 24th International Conference on Design of Communication 2006-10-18 p.149-156

ACM Digital Library Link

Summary: Legacy application systems have been widely used by user communities, and by individual users. They are currently providing a variety of functions required by system development requirements. For the development of a new 3D system using such legacy systems, we need both (i) the migration of legacy systems into a new 3D system environment, and (ii) interoperations among these systems. This paper proposes a framework for the ad hoc integration of a 2D legacy GIS, legacy simulators, and legacy databases, which are not a priori assumed to be integrated with each other. For this purpose, we first propose a mechanism to migrate a 2D legacy system with its GUI into a 3D environment. This mechanism is based on a special coordinate transformation for both the texture mapping and the event dispatching. It enables us to use a 3D terrain model with a shadow copy of a 2D legacy GIS. As for legacy geographic simulators and legacy databases without any GUI, we provide them with their proxy objects. These proxy objects can interoperate with each other, and also with the shadow copy of a 2D legacy GIS through their slot connections. As a result, our approach enables us to dynamically integrate multiple independent legacy simulators and/or legacy databases with a 2D legacy GIS simply through the composition of their 3D display objects.

[14] Topic-oriented query expansion for web search Browsers and UI, web engineering, hypermedia & multimedia, security, and accessibility / Wang, Shao-Chi / Tanaka, Yuzuru Proceedings of the 2006 International Conference on the World Wide Web 2006-05-23 p.1029-1030

Keywords: information bottleneck, intercluster similarity, intracluster similarity, query expansion, term-term similarity matrix, topic-oriented

ACM Digital Library Link

Summary: The contribution of this paper includes three folders: (1) To introduce a topic-oriented query expansion model based on the Information Bottleneck theory that classify terms into distinct topical clusters in order to find out candidate terms for the query expansion. (2) To define a term-term similarity matrix that is available to improve the term ambiguous problem. (3) To propose two measures, intracluster and intercluster similarities, that are based on proximity between the topics represented by two clusters in order to evaluate the retrieval effectiveness. Results of several evaluation experiments in Web search exhibit the average intracluster similarity was improved for the gain of 79.1% while the average intercluster similarity was decreased for the loss of 36.0%.

[15] Interactive web-wrapper construction for extracting relational information from web documents Posters / Sugibuchi, Tsuyoshi / Tanaka, Yuzuru Proceedings of the 2005 International Conference on the World Wide Web 2005-05-10 v.2 p.968-969

Keywords: information extraction, user interfaces, web wrappers

ACM Digital Library Link

Summary: In this paper, we propose a new user interface to interactively specify Web wrappers to extract relational information from Web documents. In this study, we focused on improving user's trial-and-error repetitions for constructing a wrapper. Our approach is a combination of a light-weight wrapper construction method and the dynamic previewing interface which quickly previews how generated wrapper works. We adopted a simple algorithm which can construct a Web wrapper from given extraction examples in less than 100 milliseconds. By using the algorithm, our system dynamically generates a new wrapper from a stream of user's mouse events for specifying extraction examples, and immediately updates a preview result that shows how the generated wrapper extracts HTML nodes from a source Web document. Through this animated display, a user can make a lot of wrapper construction trials with various different combinations of extraction examples by only moving a mouse on the Web document, and reach a good set of examples to obtain an intended wrapper in a short time.

[16] Multispace information visualization framework for the intercomparison of data sets retrieved from web services Posters / Itoh, Masahiko / Tanaka, Yuzuru Proceedings of the 2005 International Conference on the World Wide Web 2005-05-10 v.2 p.970-971

Keywords: IntelligentBox, WorldBottle, visualization, web service

ACM Digital Library Link

Summary: We introduce a new visualization framework for the intercomparison of more than one data set retrieved from Web services. In our framework, we use more than one visualization space simultaneously, each of which visualizes a single data set retrieved from the Web service. For this purpose, we provide a new 3D component for accessing Web services, and provide a 3D space component, in which data set retrieved from the Web service is visualized. Moreover, our framework provides users with various operations applicable to these space components, i.e., union, intersection, set-difference, cross-product, selection, projection, and joins.

[17] Extraction and classification of facemarks Long papers: affective computing / Tanaka, Yuki / Takamura, Hiroya / Okumura, Manabu Proceedings of the 2005 International Conference on Intelligent User Interfaces 2005-01-10 p.28-34

ACM Digital Library Link

Summary: We propose methods for extracting facemarks (emoticons) in text and classifying them into some emotional categories. In text-based communication, facemarks have gained popularity, since they help us understand what writers imply. However, there are two problems in text-based communication using facemarks; the first is the variety of facemarks and the second is lack of good comprehension in using facemarks. These problems are more serious in the areas where 2-byte characters are used, because the 2-byte characters can generate a quite large number of different facemarks. Therefore, we are going to propose methods for extraction and classification of facemarks. Regarding the extraction of facemarks as a chunking task, we automatically annotate a tag to each character in text. In the classification of the extracted facemarks, we apply the dynamic time alignment kernel (DTAK) and the string subsequence kernel (SSK) for scoring in the k-nearest neighbor (k-NN) method and for expanding usual Support Vector Machines (SVMs) to accept sequential data such as facemarks. We empirically show that our methods work well in classification and extraction of facemarks, with appropriate settings of parameters.

[18] Clip, connect, clone: combining application elements to build custom interfaces for information access Document interaction / Fujima, Jun / Lunzer, Aran / Hornbaek, Kasper / Tanaka, Yuzuru Proceedings of the 2004 ACM Symposium on User Interface Software and Technology 2004-10-24 p.175-184

ACM Digital Library Link

Summary: Many applications provide a form-like interface for requesting information: the user fills in some fields, submits the form, and the application presents corresponding results. Such a procedure becomes burdensome if (1) the user must submit many different requests, for example in pursuing a trial-and-error search, (2) results from one application are to be used as inputs for another, requiring the user to transfer them by hand, or (3) the user wants to compare results, but only the results from one request can be seen at a time. We describe how users can reduce this burden by creating custom interfaces using three mechanisms: clipping of input and result elements from existing applications to form cells on a spreadsheet; connecting these cells using formulas, thus enabling result transfer between applications; and cloning cells so that multiple requests can be handled side by side. We demonstrate a prototype of these mechanisms, initially specialised for handling Web applications, and show how it lets users build new interfaces to suit their individual needs.

[19] Interactive interfaces of Treecube for browsing 3D multimedia data Extending to multidimensional interfaces / Tanaka, Yoichi / Okada, Yoshihiro / Niijima, Koichi Proceedings of the 2004 International Conference on Advanced Visual Interfaces 2004-05-25 p.298-302

Keywords: 3D multimedia, IntelligentBox, Treecube, Treemap, information visualization, multimedia browser

ACM Digital Library Link

Summary: The authors of this paper have already proposed Treecube which is a visualization tool for browsing 3D multimedia data. In this paper, the authors also propose its interactive interfaces for efficiently browsing 3D multimedia data. Treecube is regarded as a 3D extension of treemap, which is a visualization tool for hierarchical information proposed by Ben Shneiderman et al. in 1992. For treemap, there are several layout algorithms: slice-and-dice, ordered treemap, strip treemap and so on. Furthermore, quantum treemap exists. It means a quantization version of these treemap layout algorithms. The authors implemented mainly three layout algorithms, i.e., slice-and-dice, ordered and strip treecube algorithm, and implemented their quantization version. Practically sophisticated interfaces are necessary for efficiently browsing 3D multimedia data. In this paper, the authors also propose such interfaces. The authors implemented mainly five interface functionalities for the following operations. (1) "Cutting plane" concept to solve the occlusion problem, i.e., nodes located before the plane are hidden to make it easy to see inside nodes. (2) The control of node frames, i.e., their brightness and thickness, for easily understanding the hierarchical structure of nodes. (3) Standard operations for the translation and the rotation of an eye position, and for the zoom in/out. (4) Particular operations for the extraction of the user focus node and for the backward/forward for browsing such node. The authors also implemented (5) a function to assign color information to any node properties because color is the most important factor of the visual display properties.

[20] C3W: clipping, connecting and cloning for the web Posters / Fujima, Jun / Lunzer, Aran / Hornbæk, Kasper / Tanaka, Yuzuru Proceedings of the 2004 International Conference on the World Wide Web 2004-05-17 v.2 p.444-445

Summary: Many of today's Web applications support just simple trial-and error retrievals: supply one set of parameters, obtain one set of results. For a user who wants to examine a number of alternative retrievals, this form of interaction is inconvenient and frustrating. It can be hard work to keep finding and adjusting the parameter specification widgets buried in a Web page, and to remember or record each result set. Moreover, when using diverse Web applications in combination -- transferring result data from one into the parameters for another -- the lack of an easy way to automate that transfer merely increases the frustration. Our solution is to integrate techniques for each of three key activities: clipping elements from Web pages to wrap an application; connecting wrapped applications using spreadsheet-like formulas; and cloning the interface elements so that several sets of parameters and results may be handled in parallel. We describe a prototype that implements this solution, showing how it enables rapid and flexible exploration of the resources accessible through user-chosen combinations of Web applications. Our aim in this work is to contribute to research on making optimal use of the wealth of information on the Web, by providing interaction techniques that address very practical needs.

[21] Meme media architectures for re-editing and redistributing intellectual assets over the Web ARTICLE / Tanaka, Yuzuru / Ito, Kimihito / Kurosaki, Daisuke International Journal of Human-Computer Studies 2004 v.60 n.4 p.489-526

Summary: While current Web technologies have allowed us to publish intellectual assets in world-wide repositories, and to browse the resulting massive accumulation, we have no effective tools yet to flexibly re-edit and redistribute such intellectual assets for their reuse in different contexts. Open Hypermedia Systems addressed the problem of augmenting third-party applications in 90 s, and more recently Web augmentation. We need extended OHS technologies for the advanced reuse of Web-published intellectual assets through re-editing and redistributing them. Meme media and meme pool technologies will work as such extended Open Hypermedia Systems technologies to annotate, re-edit, and redistribute Web-published assets. This paper reviews the IntelligentPad and IntelligentBox meme media architectures together with their potential applications, and proposes both the use of XML/XSL or XHTML to define two-dimensional meme media objects. When applied to Web contents, meme media technologies make the World Wide Web operate as a meme pool, where people can publish their intellectual assets as Web pages, access some Web pages to extract some of their parts as meme media objects through drag-and-drop operations, visually combine these meme media objects together with other meme media objects to compose new intellectual assets, and publish these assets again as Web pages. Our framework creates a new vista in the circulation and reuse of our knowledge represented as multimedia documents and/or application programs, especially in the field of science.

[22] A visual environment for dynamic web application composition Web engineering / Ito, Kimihito / Tanaka, Yuzuru Proceedings of the Fourteenth ACM Conference on Hypertext 2003-06-11 p.184-193

ACM Digital Library Link

Summary: HTML-based interface technologies enable end-users to easily use various remote Web applications. However, it is difficult for end-users to compose new integrated tools of both existing Web applications and legacy local applications such as spreadsheets, chart tools and database. In this paper, the authors propose a new framework where end-users can wrap remote Web applications into visual components called pads, and functionally combine them together through drag & drop-paste operations. The authors use, as the basis, a meme media architecture IntelligentPad that was proposed by the second author. In the IntelligentPad architecture, each visual component called a pad has slots as data I/O ports. By pasting a pad onto another pad users can integrate their functionalities. The framework presented in this paper allows users to visually create a wrapper pad for any Web application by defining HTML nodes within the Web application to work as slots. Examples of such a node include input-forms and text strings on Web pages. Users can directly manipulate both wrapped Web applications and wrapped local legacy tools on their desktop screen to define application linkages among them. Since no programming expertise is required to wrap Web applications or to functionally combine them together, end-users can build new integrated tools of both wrapped Web applications and local legacy applications.
