    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»

    Designing documents, such as writing a technical paper, manual or WWW home pages, starts with a goal in mind but often does not simply proceed in a top down problem solving style. The document design process consists of a cycle of interpretation, modification and understanding. It requires both generating parts (words, sentences, and paragraphs) and structuring them while exploring what to write. ... View full abstract»

    Because of the recent explosive increase in the number of WWW documents, directory services are becoming indispensable. In the keyword search function of most directory services, search results are displayed as a URL list ordered by importance as calculated by the system, but the order sometimes does not have any meaning to the user since the calculation algorithm is a black box. In addition, it i... 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»

    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»

    In collaborative design, participants usually have different backgrounds and standpoints. Due to these differences, it is hard for participants to mutually understand intentions, and they must make a lot of effort to reach a mutual agreement on the design. Thus, the efficiency of the design processes is decreased. We propose a framework to support participants in mutual understanding by grasping a... View full abstract»

    A system aiming at implementing 3D sound, so called, 3DSGS (3D Sound Generation System), is introduced. This system supplies spatial attributes of a sound source which occurred in a particular place to other dull sounds faithfully, which is made possible by utilizing HRTF (Head Related Transfer Function) as convolution filter to modify spectral characteristics of the input source. The 3DSGS develo... 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»

    The paper introduces a novel technique for producing augmented reality systems that simultaneously identify real world objects and estimate their coordinate systems. This method utilizes a 2D matrix marker, a square shaped barcode, which can identify a large number of objects. It also acts as a landmark to register information on real world images. As a result, it costs virtually nothing to produc... 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»

    The tendency in user interface design is to support interaction styles that resemble our interaction with our natural environment. In practice, this has resulted in adaptive, multimodal user interfaces. Concerning output, designers are challenged to create interfaces with multimodal output elements in which single messages from a designer to a user are presented in multiple forms, i.e., redundancy...

    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»

    The paper describes a study which investigates the extent to which multimedia developers apply formal design approaches when creating educational multimedia titles. For the purpose of this study a formalised design approach is defined as one which is documented and repeatable. The findings of this study suggest extreme diversity in the approaches used to design educational multimedia, and a low le... 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»

  • Pattern languages for usability: an investigation of alternative approaches

    Publication Year: 1998, Page(s):25 - 30
    Cited by:  Papers (7)
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (48 KB)

    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»
