Temporal Issues of Animate Response

Increased capacities of personal workstations enable graphical user interfaces to offer natural human computer interaction. This leads to the possibility of animate response, i.e., natural transitions from one state to another. It is recognized that for optimal efficiency such animate response should be “tuned” to the time frame of the user. It is not sufficient to speed up the response as much as possible: the temporal characteristics of the response should be based on human perceptual capabilities. This paper is a survey of notions related to animate response. Throughout the paper we will touch upon subjects which need consideration and/or further investigation.CR Categories and Subject Descriptors: I.3.3[Computer Graphics]: Picture/Image Generation — Display algorithms;I.3.5[Computer Graphics]: Computational Geometry and Object Modelling — Curve, surface, solid, and object representations;I.3.6[Computer Graphics]: Methodology and Techniques — Interaction techniques
