Multimedia and process control interfaces: signals or noise?

IMPACT Research Group, Department of Computer Science, Loughborough University, Loughborough, Leicestershire LE11 3TU, UK

Multimedia interfaces are examined and the nature of current input and output media identified. A number of design objectives for multimedia inteifaces are suggested - improving efficiency, learning and providing a stimulating problem-solving environment. The key problem of how to choose an appropriate medium for a particular interface situation is analysed and the concept of a signal-to-noise ratio for measuring media expressiveness is tentatively postulated. Some recent work in process control is then examined and the results interpreted from the signal-to-noise ratio viewpoint. These are then related to the concept of media expressiveness.

Key Words: Multimedia • interface design • methodology • empirical • process control
