Recent improvements in the human factors elements incorporated in the design of personal computer interfaces are illustrated by detailed analyses of two microcomputers and their word processors (Osborne 1/WordStar and Apple's Macintosh/MacWrite). The vital steps in operation are described through analyses of the behavioral requirements involved in…

Compares the five classic graphic design principles used to construct visual messages--proportion, sequence, emphasis, unity, and balance--with relevant human factors research findings. Compiled by Williges and Williges (1981) these findings focus on the structuring of information for visual displays in interactive environments. (MBR)

Reports the results of two formative research studies conducted during the design process for a new, portable trackball-like computer input device for small children. The findings are discussed in terms of the design of appropriate interfaces for young children, and what can be learned from formative research on products in development. (25…
