Abstract

This paper presents a new methodology for performing theory-based evaluations of user interface designs early in the design cycle. The methodology is an adaptation of the design walkthrough techniques that have been used for many years in the software engineering community. Traditional walkthroughs involve hand simulation of sections of code to ensure that they implement specified functionality. The method we present involves hand simulation of the cognitive activities of a user, to ensure that the user can easily learn to perform tasks that the system is intended to support. The cognitive walkthrough methodology, described in detail, is based on a theory of learning by exploration presented in this paper. There is a summary of preliminary results of effectiveness and comparisons with other design methods.
