Assessing usability with eye-movement frequency analysis
Minoru Nakayama, Makoto Katsukura · 2008
Eye-movements can be an index of usability, though there is no significant relationship between a subjective usability score and indices of eye-movements, however [Nakayama and Katsukura 2007]. A possible reasons for this is the shortness of the observational duration. As another approach, power spectrum density (PSD) and cross spectrum density (CSD) of eye-movements can be used as an index of mental workload [Nakayama and Shimizu 2004]. This paper addresses the possibility of assessing usability using frequency analysis of eye-movements.
