In this paper, we propose contents sharing model for consolidating distributed collaboration environments. We provide the combined model by integrating different features-scalable resolution display walls resource, sharing contents on local and remote, multi-user interaction, and access control. There is a benefit that every user can interact within an environment, but overlaps would occur because of multi-user interaction. To manage overlap issue, the model includes access control. Access control would interfere flow of work process. Therefore, we conduct user study to evaluate these two factors of the model. The result shows that the proposed contents sharing model makes it possible to concentrate in a work.
