    Summary form only given. Our concern is to exploit user behaviour in the interaction between humans and computers. By doing this we expect to move towards adaptive human-computer interaction. The work reported addresses the coordinated use of user behaviours and meta-data generated during interactive computer-mediated information searches. The context used to develop this idea is that of searching... View full abstract»

    3D-graphics popularity has steadily increased in a number of areas such as entertainment, scientific visualization, simulation, and virtual reality. Despite this rapid growth the authoring of animated 3D objects in virtual environments is still by no means trivial. This article presents new concepts of the animated 3D programming language SAM (Solid Agents in Motion) and its programming environmen... View full abstract»

  • Supporting 3D warping visual feedback for virtual reality

    Publication Year: 1998, Page(s):14 - 21
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (476 KB)

    Cartoon animation techniques have previously been used to enhance the illusion of direct manipulation in 2D graphical user interfaces. In particular, animation can convey a feeling of substance in the objects being manipulated by the user. The paper presents the expansion of this concept to 3D graphical objects manipulated in a virtual reality domain. Three effects using 3D warping are presented t... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (44 KB)

    It is widely recognised that multiple modes of input give higher recognition rates than single modes. The use of multiple modes, such as speech and gesture, can allow for more natural human-computer interaction. Opportunities for error and ambiguity resolution also occur, as the same information may be available from more than one source, providing redundant or repeated information. This paper pre...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (148 KB)

    In interactive pictures or virtual reality (VR) scenes where no explicit buttons exist, users may be overwhelmed by the number of possible and perfectly logical locations in which hot spots might be embedded. In any particular scene, the users are too often left to their own devices in order to find hot spots (portals, gates, links). This problem becomes even more acute in photo-realistic environm...

    We apply some aspects of cognitive work analysis to the anaesthesia domain-in particular, the design of equipment used in the operating theatre for monitoring oxygen saturation in arterial blood (pulse oximetry). Work domain analysis (WDA) provides us with initial models of the work domain of anaesthesia, of the subdomain of pulse oximetry, and of the human body, and activity analysis (AA) helps u...

    One way to enhance the usability of a computer system is to improve the appearance (beauty) of the user interface. The research reported here concerns making computers easier to learn and use by improving interface aesthetics through the use of aesthetic measures for evaluating screen layouts. We introduce five aesthetic measures: balance, equilibrium, symmetry, sequence, and order and complexity.... View full abstract»

  • Towards an approach for novel design

    Publication Year: 1998, Page(s):186 - 191
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (40 KB)

    We contrast the design of traditional technology with the design of new technology. Gathering from our experience, we argue that traditional HCI design techniques are not directly applicable to the design of new technology. We review some of these techniques and show how they should be adapted to be used in the context of novel design. As part of this discussion, we show that user input in the pro...

    Microsoft Windows 95 uses both vertical arrangements of items in lists and horizontal groupings of smaller vertical lists. This paper reports the results of an experiment to evaluate selection times using horizontal and vertical lists. Two GOMS (Goals, Operators, Methods, Selection rules) models were developed to predict differences. There was no significant difference in selection times, but the ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (236 KB)

    In many operational contexts, data visualisation techniques are used to convey accurate and easily comprehended information to human analysts. One popular approach is to represent domains of interest in terms of the objects they contain and measures of the similarity between them. Spatial data visualisations can then be generated which place objects so that those which are more similar lie nearer ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (96 KB)

    Software engineering (SE) and human computer interaction (HCI) disciplines typically have separate processes and design artifacts. The paper describes a coevolutionary design process, which incorporates both SE and HCI processes, and indicates how design artifacts can be usefully shared throughout the development of an interactive product. We show how scenarios in particular can serve as a bridge ... View full abstract»

    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (32 KB)

    The ecological approach has traditionally been used for analysing process control type, physically coupled causal system domains to identify structural associations between the physical components of a system and the abstract functions of the system. Systems are then designed to represent the system's structural links as optical invariants in configural displays (J. Rasmussen, 1986; K.J. Vicente a... View full abstract»

    How should the customer specify usability requirements in a tender situation? This is particularly difficult if the product is a standard system with enhancements, since the customer cannot prescribe a specific user interface. Furthermore it must be possible to verify the usability requirements with a reasonable effort, and the requirements must not discourage serious proposers. The paper discusse... View full abstract»
