Haptic Interface for Shape and Texture Recognition of Remote Objects by Using a Laser Range Finder

This paper proposes a system that enables users to recognize the shapes and textures of remote objects with 1-degree of freedom (DOF) haptic feedback. The system consists of a camera platform and a handheld haptic interface. The platform is equipped with a laser range finder, which can be tilted and panned. The handheld interface can generate a 1-DOF reaction force proportional to the distance measured by using a laser range finder (LRF) on the camera platform. The LRF rotates synchronously according to the translational and rotational motion of the handheld interface. In addition, a stereoscopic display indicates a real-time stereoscopic video image of a remote site captured by a stereo camera.
