Abstract :
The effectiveness of four techniques in evaluating the usability of a graphical user interface is presented. The techniques are heuristic evaluation, usability testing, guidelines, and cognitive walkthrough. The techniques are compared as to the number, type, and severity of the problems each could identify for a specific product.<>
