Abstract
The three primary sensory dimensions along which user-computer interaction can occur are visual, tactile, and auditory. In this article, several guiding principles for manipulating such parameters to produce innovative, productive, and economically sound microcomputer interface designs are presented. Some of these design considerations are illustrated using the Scheduled/Unscheduled Observations Subsystem, which is in operation in the Toxicology area at Ortho Pharmaceutical Corporation. This system was originally designed for an early microcomputer (the Vector Graphics System B—CP/M; Z-80), and was recently ported successfully to a Hewlett Packard Vectra (IBM PC/AT compatible-80286; MS-DOS). Finally, some new frontiers of microcomputer interfaces are mentioned briefly.
