    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»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (144 KB)

    This prototype is a multimedia system for use by speech therapists to assist in the rehabilitation of motor-impaired patients. These may be stroke victims who have to re-learn the ability to communicate effectively. The process is laborious and usually conducted in a one-to-one situation where the interaction between the therapist and the client depends on visual and audio cues. Instead of the usu...

  • 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...

    Older driver testing in Australia, and around the world, is misguided. It relies on the opinion of health professionals rather than the capacity to drive safely. This paper examines the relationship between traffic tickets issued and a range of vision tests and concludes that the nature of the relationship suggests that tests of cognitive capacity might be more appropriate View full abstract»

  • Integrating speech and two-dimensional gesture input-a study of redundancy between modes

    Publication Year: 1998, Page(s):6 - 13
    Cited by:  Patents (1)
    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...

  • Designing effective navigation for photo-realistic VR environments

    Publication Year: 1998, Page(s):4 - 5
    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...

    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»

    We present a new method for capturing requirements and priorities that can be used in the development of highly innovative interactive systems. We are concerned with the development of interactive systems that cannot be treated simply as incremental improvements over existing products. In such cases, it is not possible to identify user requirements on the basis of empirical techniques, as there ar... View full abstract»

    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»
