ABSTRACT:
A system that includes a desk top assembly of a display and sensors mounted on a robotic arm. The arm moves the assembly so that it remains within position and orientation tolerances relative to the user's head as the user looks around. Near-field speaker arrays supply audio and a microphone array senses a user's voice. Filters are applied to head motion to reduce latency for arm's tracking of the head. The system is full duplex with other systems allowing immersive collaboration. Lighting and sound generation take place close to the user's head. A haptic interface device allows the user to grab the display/sensor array and move it about. Motion acts as a planar selection device for 3D data. Planar force feedback allows a user to “feel” the data. Users see not only each other through display windows, but can also see the positions and orientations of each others' planar selections of shared 3D models or data.
