Abstract

Temporal properties of interaction have a profound impact upon the usability of human computer interfaces. Delays in response time can lead to frustration and error. The simultaneous presentation of many different pieces of information imposes heavy demands upon the cognitive and perceptual resources of system operators. These problems have been investigated by a number of recent research initiatives. Unfortunately, it has been difficult to replicate the results that have been obtained from experimental investigations. This creates significant problems for designers if these results are to guide the future development of interactive systems. This paper briefly describes how an multi-disciplinary team has addressed this problem during the Temporal Aspects of Usability (TAU) project.
