We present CoVAR, a novel remote collaborative system combining Augmented Reality (AR), Virtual Reality (VR) and natural communication cues to create new types of collaboration. AR user can capture and share their local environment with a remote user in VR to collaborate on spatial tasks in shared space. COVAR supports various interaction methods to enrich collaboration, including gestures, head gaze, and eye gaze input, and provides virtual cues to improve awareness of a remote collaborator. We also demonstrate collaborative enhancements in VR user's body scaling and snapping to AR perspective.
