Abstract
The communication link between the human and the technology is a key operational level interface; it is at this level that the human is able to exert control over the machine, or to enter data or receive information from the machine. This means that the devices that support the interaction across this interface will fall into two classes: input and output, synomonous with control and display (at least as far as the human is concerned). If we make the simple assumption that control can be discrete or continuous, then we can begin to determine the sort of information a Person might require to perform such control, and the type of device which would support the control actions.

Wilbert 0 Galitz, It’s Time To Clean Your Windows: Designing GUIs That Work, Wiley, New York, 1994.
This continues the theme of Galitz’s previous book on office automation and user interface screen design, by focusing on display screen design. He does this within the context of graphical user interfaces, covering direct manipulation, windows, menus, icons, etc., as well as user considerations.
David Oborne, Ergonomics at Work: Human Factors in Design and Development, Wiley, Chichester, 1995.
This text, first published in the 1980s, and now in its third edition, provides an excellent introduction to the topic of ergonomics, covering interface, workplace and environmental design issues. The approach taken tends to be from the physiological perspective: for example, two of the early chapters cover the structure of the body in terms of the sensory nervous system, body size and movement. However, the level of detail is generally impressive.
Chris Baber, Beyond the Desktop: Designing and Using Interaction Devices (Computers and People Series), Academic Press, London, 1997.
This text considers how interaction devices in human-computer interaction have developed and how they are used, as well as discussing implications for future design and development. It considers the ergonomics of keyboards, pointing devices and speech input, and covers devices for use in ‘restricted environments’ and multi-modal interactions.
Jeffrey Anshel, Visual Ergonomics in the Workplace, Taylor and Francis, London, 1998.
To quote the backcover, this text is an easy-to-read introduction to the role of the visual system in the workplace. It covers how the visual system works, including an historical perspective of how it has evolved, and issues relating to computer use, and includes many practical exercises and tips. The appendices provide an incredible amount of information relating to resources for visually impaired individuals.
