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.
