Visualization

Abstract

Users of information systems must deal with a great variety of visualizable objects and patterns of objects. Representations of those objects are distinguished according to five different spaces (physical, logical, software, interface, user-conceptual) within which they may be defined and/or visualized. The conceptual framework, although based in the user's mind, must reflect and transcend the other four spaces. 'Conceptual distance' is proposed as a measure having different effects on the user's required mental effort, depending upon which of the information spaces is involved. The challenge is to determine user-oriented structures and techniques that can be used to display information objects and patterns on the visible surface (interface space), in a manner that will minimize the user's mental (visualization) efforts.
