This poster presents an Augmented Reality (AR) system for remote collaboration that allows a remote user to navigate a local user's scene, independently from their viewpoint. This is achieved by using a 3D scan and reconstruction of the user's environment. The remote user can place virtual objects in the scene that the local user views through a head mounted display (HMD), helping them place real objects. A user study tested how the amount of remote view independence affected collaboration. We found that increased view independence led to faster task completion, more user confidence, and a decrease in verbal communication, but object placement accuracy remained unchanged.

This paper describes an AR system for remote collaboration using a captured 3D model of the local user's scene. In the system a remote user can manipulate the scene independently of the view of the local user and add AR annotations that appear projected into the real world. Results from a pilot study and the design of a further full study are presented.
