This paper describes a novel approach that can be used to determine the focal object that a robot is looking at and introduces the unique robotic eye, AttractiveEye. Humans have the visual input mechanism but do not have the output mechanism concerning the visual signal except gestures. AttractiveEye can communicate information regarding the color of an object by changing its color to match that of...
While most mobile robots possess the ability to navigate to and from given locations, for a robot to truly perform guidance, human awareness is also needed. Our guidance robot system possesses both, using a wireless sensor network for navigation and a vision-based tracking system for human awareness. We use the network to create a virtual directional field for the robot. As the network is ad-hoc and...
This paper describes a novel display system of a three-dimensional (3-D) image. The proposed system employs a projector, a camera, and a hand-held screen. User can observe a 3-D image embedded in the space by holding up the hand-held screen at an arbitrary position. In the proposed method, the 3-D position of the hand-held screen is measured by the shadow created by projection light. By using this...
