Augmentation of check in/out model for remote collaboration with Mixed Reality

This paper proposes augmentation of check in/out model for remote collaboration with Mixed Reality (MR). We add a 3D shared and private space into the real workspace by MR technology, and augment the check in/out model to remote collaboration. By our proposal, user can intuitively receive remote partner´s work via virtual objects in the shared space and stop sharing information about an object by just moving the object into the private space if the user doesn´t want to share it. We implement a system which achieves our proposal and evaluate it.
