✦ Synopsis


Picture-symbol languages can provide an appropriate alternative communication mechanism for the non-vocal, and a microcomputer-based system to mediate pictographic linguistic expression has been developed. The design of such a system imposes specific requirements at the human-computer interface both directly, in relation to the ease of user interaction, and indirectly, in terms of the suitability of the symbol forms adopted to convey message information. Both aspects have been investigated, and it is shown that emphasising the first of these areas gives rise to design criteria which can largely overcome problems arising in current practice within the second.
