Active information display without occlusion using UD-m

An active information display system offers human-centered service, which projects visual information according to human gaze. Proposed system is based on Intelligent Space, and uses a mobile robot with a projector. In this system, occlusion of visual information can be occurred by various reasons such as human, obstacles and so on. It is difficult to offer precise visual information, when the occlusion is occurred. Therefore, we should find the position that can prevent occlusion. We propose a method that controls the position of a mobile robot to prevent occlusion by human and robot. Moreover, we simulate to verify our method.
