Evaluation of Incongruent Feeling During Mouse Operation Using Eye Gaze and EEG

Abstract

One of the most important issues in the design of a personal computer or a game is creating an interface that a user can operate without a feeling a sense of incongruity between their actions and what appears on the screen. Since the degree of incongruent feeling varies from person to person, it is important to focus on the physiological processes of the user in elucidating the mechanisms underlying the occurrence of this feeling. In this study, we recorded electroencephalography (EEG) and eye gaze from individuals while they completed a simple task using a mouse to move a cursor on a screen. By changing the setting of the mouse speed, we were able to create an environment where the psychological state of incongruent feeling was likely to occur. After each trial, we asked individuals whether they experienced a feeling of incongruency. We then, compared the EEG and eye gaze responses for when the feeling of incongruency occurred and when it did not occur.
