Improving Visual Fidelity of Gaze-Dependent Color Image Presentation Using High-Speed Projection

Large displays and projectors have been widely used in public spaces to present information to multiple viewers simultaneously. While such approaches enable efficient information sharing, they cannot personalize content for individual viewers, and existing solutions using HMDs or camera-based tracking are impractical in public settings due to device scalability and privacy concerns. As an alternative, methods based on high-speed projection have been proposed, in which images become visible only when motion occurs in the viewer’s gaze or observation target. In this paper, we propose a colorization method for gaze-dependent image presentation using a high-speed projector that was not achieved by previous approaches, and investigate how variations in the proposed method’s parameters affect the fidelity of the presented images.
