An approach supporting spatial workspace collaboration via a video-mediated communication system is described. Based on experimental results, the following were determined to be the system requirements to support spatial workspace collaboration: independency of a field of view, predictability, confidence in transmission and sympathy toward the system. Additionally, a newly developed camera system, the GestureCam System, is introduced. A camera is mounted on an actuator with three degrees of freedom. It is controlled by master-slave method or by a touch-sensitive CRT. Also, a laser pointer is mounted to assist with remote pointing. Preliminary experiments were conducted and the results are described herein.
