Abstract

Although the primary beneficiary of interactive computer graphics systems is supposedly the human user, the latter has normally been forced to adapt to the former. Instead, the graphical user-computer interface should be deliberately tailored to accomodate, complement and supplement the user. This can be achieved by designing hardware and software devices and tools to be responsive to the user mental processes and preferences involving cognition and affecting behavior. But efforts at systematic identification and validation of the significant user-required or user-expected characteristics have been rare. This paper gives an overview of the background, presents a framework of characteristics, suggests a differentiation of stages of user-computer interaction, and, finally, discusses some related methodological problems.
