Abstract: Work support systems using projectors realize greater work accuracy than systems that use head-mounted displays because such system can directly add digital information to an existing object. However, projection information may be hidden by the user's hand (hand occlusion) and content may be difficult to recognize. Thus, we propose methods to manage hand occlusion that occurs when tracing a line, with a focus on visual and auditory feedback. The proposed method was evaluated quantitatively and qualitatively in a user study, and the effectiveness of combining visual and auditory feedback was recognized.
