When a person works in spatial workspace with his or her partner at the remote site, they encounter many difficulties that they never encounter when they work together at the same place. We address one of the known difficulties in distributed spatial workspace collaboration—disagreement of observational viewpoint. We propose a framework to analyze the problem related to disagreement of viewpoints. According to our framework, the cognitive load to align between the view of the other site and the view of the real workspace disturbs their communication and efficiency of their work. We analyze some problems about disagreement of observational viewpoint in distributed spatial workspace collaboration and functions of some groupware systems. Moreover, we develop a support system for distributed spatial workspace collaboration. The system automatically aligns one's reference frame and that of other site. The system is expected to reduce the cognitive load to align the reference frames and to facilitate distributed spatial workspace collaboration.
