Eye Movement-Based Interface Evaluation: What can and Cannot be Assessed?

Abstract

Interface evaluation by eye tracking-derived data is discussed in this review and synthesis paper. While analysis of eye movements during interface use is becoming more popular, there is little basis for justification of eye tracking methods. A review of traditional interface assessment methods and criteria is provided, to establish areas where eye tracking may potentially impact interface evaluations. Studies are then reviewed, that have used eye tracking-derived measures for performance assessment as interfaces are manipulated. A synthesis is then provided, suggesting that eye tracking-based analysis could have a positive impact in evaluations of consistency, resources, visual clarity, and flexibility, and should have difficulty in ascertaining interface compatibility and locus of control.
