    In distributed conference systems, participants get access to the shared documents through the computer network. The authors describe requirements in distributed conferences regarding access rights to shared documents. We give four categories of hypermedia representation based on access rights and two principles of human interface design to avoid mismatch between access rights and oral communicati...

    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»

    The storyboarding stage in filmmaking is necessary for communicating overall scenarios rapidly through approximate visual drawings. In contrast, most 3D animation systems produce final products through repeated precise modeling. The interaction suggested in the paper promotes the maximum transfer of the users' knowledge of physical human actions into virtual environments, so the users can rapidly ... View full abstract»

    Cartoon animation techniques have previously been used to enhance the illusion of direct manipulation in 2D graphical user interfaces. In particular, animation may be used to convey a feeling of substance to the objects being manipulated by the user. The paper presents an expansion of this concept to 3D graphical object manipulation. A standard set of 3D direct manipulation operations have been ex... View full abstract»

    Today's interactive systems have provided sophisticated recovery tools that help protect users from their own mistakes. Although many graphical and direct manipulation user interfaces have undo/redo capabilities that allow the user to reverse erroneous actions, their undo/redo tools present only command history of textual representation which make if difficult for the user to identify the desired ...

    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»

    The authors propose the icon-based animation of software requirement specifications by using the object and dynamic models of the OMT methodology. In order to produce icon-based animation, they use “graphical classes” and “icon transformations.” In general, the graphical classes are defined for each class of the object diagram. The icon transformations which show the activi... View full abstract»

    We propose a Visual Pointing Out System (VPOS) using a finger tip to indicate a character string from a pair of color images to a computer or a robot. The image pair consists of an image with character strings and a hand, and an image without a hand. This system includes the segmentation of the string regions, the extraction of the hand region, the specification of the finger tip and the extractio... View full abstract»

    A visual system called Eviss is proposed. Visual systems proposed so far have been fixed on certain specifications. It is hard to make and modify such visual systems. Since Eviss has a spatial parser generator based on CMGs, it can construct various visual systems if provided with grammars which consist of production rules. In Eviss, a person who implements a visual system first defines production... 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»

    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»

    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»

    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»

    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»
