Gaze Behavior and Emotion of Crane Operators for Different Visual Support System

This study described a method of using glance behavior as design indices of In-Vehicle Visual Support (IVVS) system. The method was implemented to evaluate information content of the IVVS to facilitate operation of a mobile crane, which was challenging due to depth perception and load oscillation. The results suggested information content was well-discriminated using gaze behavior, which indicated its feasibility as design indices. Most importantly, emotional response was well-defined using gaze behavior. By not requiring self-evaluation of emotional response after the experimental procedure, design of IVVS could be evaluated by observing gaze behavior simultaneously during the experiment. In addition, elements of bias and social masking could be minimized because gaze response is sub-conscious.
