A human factors evaluation of the visual system component development program (VSCDP) eye-tracking system
Jerome I. Nadel, Harold D. Warner · 2003
Results of a qualitative human factors evaluation, conducted to identify the user, equipment, and environmental factors that impaired the performance of the visual system component development program (VSCDP) eye-tracking system, are presented. The evaluation was performed in two phases: an exploratory phase and a validation phase. The results of the first phase indicated that eye tracking performance directly related to pupil size. In the second phase, the eyes of two subjects were chemically dilated, and a profound improvement in eye-tracking performance was observed.>
