Abstract
Representational aiding is the development of computerized graphics that provide alternative perspectives of a domain. The goal of representational aiding is to provide interface resources that support (rather than replace) an individual in meeting the inevitable and unforeseeable challenges that arise in a domain. The design of successful representational aids depends upon both characteristics of the domain (including the tasks to be performed), and characteristics of human cognition and perception. These issues are discussed with reference to a set of representational aids that were developed for a real-world application. Empirical evaluations of these aids are discussed briefly. >
