    We have developed a new multimedia interface called Ultra Magic Key which uses “Paper”. The new interface will allow users to access multimedia information simply by “Turning over a Paper” or “Touching a Paper”. The “Paper” sheet has no electric devices or batteries. The system recognizes the “Paper” sheet and the action of a user's finge... View full abstract»

    The limitations of palmtop computers are their display size and pointing mechanisms. This makes it difficult to use them for direct manipulation of very large objects, such as World Wide Web (WWW) pages, newspapers, maps, and documents that require a large display. The paper describes a new palmtop computer with a built-in mouse on the underside of the computer. When a user moves the computer on a... View full abstract»

    Digital media such as World Wide Web or CD-ROMs enable us to publish and transfer computer graphics, digital images, or audio data in ways that were not available for paper media. Yet, paper still has many advantages. It is easier to carry, strong enough to survive dropping or bending, and it offers highest resolution for printed text and images. We have developed an augmented desk top interface, ... View full abstract»

    Iterative design is usually considered in the context of prototyping, evaluating, and improving a single product. The paper reveals our design experiences working on three banking Websites which had strong similarities, enabling us to carry many lessons over from one project to the next. We discuss our design rationale, the elaboration of our design process, and the results of our evaluations. Our... View full abstract»

    We propose an interface to browse 3D virtual space in a human scale virtual environment using a scrolling technique. Our method is based on head posture estimation by processing the image of an oval marker. Because the marker is attached to a cap, the user can wear the marker easily and naturally. Our method feels natural because the direction of scrolling is consistent with the user's direction o... View full abstract»

  • Factors determining the difficulty of practice problems in a computer language textbook

    Publication Year: 1998, Page(s):422 - 428
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1836 KB)

    We studied the factors which determine the difficulty of practice problems in a computer language textbook. The extraction of these factors from such complex problems requires considerable effort, and after extraction these factors are difficult to analyze because of their large number. An additional difficulty is that these factors cannot include the full range of human cognitive characteristics ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (48 KB)

    There are two conventional approaches to building synchronous collaborative applications: collaboration unaware and collaboration-aware. Though the unaware approach, realized by graphic level synchronization, has an advantage in that it does not require any modification of the original single user applications, it makes it difficult to support groupware specific operations. On the other hand, the ... View full abstract»

    Public information kiosks are used increasingly in Singapore to provide enquiries and services to the public. Thanks to the National IT2000 plan, such kiosks are now a common sight in public places. To ensure effective use of such kiosks, a field evaluation of a number of public information systems was conducted from a human factors perspective. The paper reports the results of the evaluation for ... View full abstract»

    Translation support systems have the ability to retrieve information quickly from large databases and dictionaries. However, current systems lack the ability to present relevant information automatically, at just the right moment, without interruptions. To allow a user seamless retrieval, an ideal system would be able to observe a translator's behavior, predict their translation processes and auto... View full abstract»

    As one of the tools for our mobile agent system, Aglets, we developed a desktop-like visual shell, called Bali, to allow natural and intuitive handling of mobile agents. By nature however, mobile agents are autonomous programs. The speed at which an agent executes its own program is very fast in comparison with the speed at which humans operate. Therefore, it is hard for a user to control an aglet... View full abstract»

    Direct manipulation interfaces are characterised according to the representation of the task domain. The domain objects and the effect of user operations on those objects. In the VR-DIS system (Virtual Reality-Design Information System), the task domain is represented by a mix of a verbal (textual) and analogue (pictorial) representation. Objects are represented by a mixture of a descriptive spati... View full abstract»

    World Wide Web (Web) tools for management of documents during formal, synchronous electronic meetings are lacking greatly at present. Such a tool provides tremendous potential for applying Web mechanisms, such as dynamic page creation, and user interfaces to document processes in meetings. Such a tool in this research is referred to as a Web Electronic Meeting Document Manager (WEMDM). The paper p... View full abstract»

    An evaluation experiment was conducted to compare four interaction modes: mouse based, pen based, pen+voice, and pen+voice+mouse modes. Subjects tested the four modes for drawing and modifying an engineering plan on a CAD system. The results show that the pen+voice+mouse mode was the best of the four modes, in terms of total manipulation time (drawing time and modification time), and the subjects'... View full abstract»

    As the opportunity of using computer systems spreads into everyday life, the importance of friendly human interfaces is increasing. As a form of next generation human interfaces, an anthropomorphic interface agent which mimics a face-to-face communication holds promise, and some early developments have started. Its multimodality including facial expression and speech dialog fits to human perceptio... View full abstract»

    In businesses, knowledge of work is represented by a sequence of related work events and management of these relations is very important for users. The paper proposes a method that automatically groups related work events from a user's operation record on a Personal Information Management system (PIM). We assume that the related work events on a PIM are operated consecutively by a user. Our method... View full abstract»

    The paper describes a method for manipulating a three dimensional object without considering conventional three independent orthogonal views. We apply the direct manipulation to operate the three dimensional object. We propose “augmented manipulation” which is an enhanced direct manipulation technique by using additional information. We implement three dimensional modeling tool “... View full abstract»

    The best way to ensure usability is to treat human factors as an input to design, rather than merely evaluating prototypes or design documentation. The capability of pattern languages to facilitate the design process, improve communication, and record design philosophies suggests that they may assist the user centred design process. Researchers have not yet investigated in detail what a pattern la... View full abstract»

    We are interested in the problem of how to lay out practical graphs where nodes vary in shape and size. Applying classical graph drawing algorithms to practical graphs may result in overlapping nodes and/or edge node intersections. This is because such algorithms were often originally designed for abstract graphs where nodes take up little or no space. To make use of such algorithms for practical ... View full abstract»

    The most conventional approach to a speech based interface has been to achieve an explicit goal as a result of spoken dialogue. On the other hand spoken dialogue has also another aspect: the simple enjoyment of making conversation with participants, a typical example being casual chatting. This aspect offers a key for creating a new style of autonomous agent, which appears not as a human assistant... View full abstract»
