Abstract

To propose a quantitative usability testing index for each step of information processing, we measured eye fixation-related potentials (EFRPs) under the condition simulating touch panel operation. A characteristic of EFRPs is that conventional usability testing or other special testing is unnecessary because eye fixation can be used as a trigger. In this study, there were two kinds of tasks such as visual cognition and search. In visual cognition tasks, after addition and subtraction, the participant input the answer by selecting orderly number corresponding to the numerical answer displayed on the monitor. In visual search tasks, a number selected randomly was displayed on the monitor, and the participant answered the question by searching the same number out of numbers arranged randomly on the monitor. And then, EFRPs were measured to estimate cognitive load for task-related information processing. EFRP data were compared with data from a usability questionnaire, revealing that EFRPs enable the quantification of cognitive load.
