Abstract:
The effort-based model of usability aids in evaluating user interface (UI), development of usable software, and pinpointing software usability defects. In this context, the term pinpoint analysis refers to identifying and locating software usability issues and correlating these issues with the UI software code. In this paper, the underlying theory of the effort-based model along with pattern recognition techniques are used to produce a framework for pinpointing usability deficiencies in software via automatic classification of segments of video file containing eye tracking results. This allows developers to harness their effort and focus on excessive effort segments that need attention. To verify the results of the pattern recognition procedures, the video is manually classified into excessive and non-excessive segments and the results of automatic and manual classification are compared. The paper details the theory of effort-based pinpoint analysis and reports on experiments performed to evaluate the utility of this theory. Experiment results show more than 40% reduction in time for usability testing.
