In this research, a subject of instruction is operation required the sight of instructor. Then, we propose “an instruction method in remote collaborative MR on the basis of viewpoint coordinates”. The instructor and the worker have their own objects, and the same size and shape 3D virtual object models appear as instruction in worker's site. These virtual object models are set on the basis of viewpoint coordinate between remote, so the relative position of the instructor and his real objects is always correspond to the relative position of the worker and virtual object models. From virtual object models, the worker can recognize how the instructor handle and watch his object. With overlapping the objects with virtual object models, the worker can perform same operations with the instructor while looking at instruction. Then we implied a system that actualizes the concept and evaluated it. As a result, we could measure the degree of separation and could prove that working efficiency advanced rather than usual.},
