A Research on Game Experience Improvement by Changing Hit Stop Duration Based on Eye Tracking
摘要
The purpose of this study is to verify whether the response changes when the hit stop, one of the components of GameFeel, is adjusted according to gaze information. We first analyzed the boundary between pleasant and unpleasant hit stop durations through player questionnaires, deriving a distinctive range of comfortable durations based on discriminant analysis. Upon establishing this boundary, we conducted a secondary experiment where the hit stop duration varied in response to the gazing duration of the player. This study included an additional experiment to validate if changing hit stop duration not only with direct gaze but also considering the visual field would impact the gaming experience. By applying a visual acuity-weighted approach to the time players spent gazing at enemies, we observed that dynamic hit stops that adapt to broader gazing contexts effectively enhance immersion and impact sensation while minimizing stress. Our findings suggest that a gaze-responsive hit stop mechanism can notably improve GameFeel by increasing both the sense of impact and realism during gameplay.
