Figure 1: (a) Mixed Reality users collaborating with shared virtual objects can encounter occlusion issues when objects block other objects from a collaborator's view.In our approach, each user has a local copy of the shared objects.To automatically align a user's perspective with their collaborator's, our technique (b) transforms the user's local objects so that the user has the same view as their collaborator.The virtual representations of the collaborator's hands transform with the objects.(c) The collaborator can see when the user is aligned with their perspective because the user's virtual hands inversely transform to reference the proper virtual position on their (un-rotated) local object.The proper positioning of the virtual hands for both users allows them to make intuitive references to the objects.
