ShowMe is an immersive mobile collaboration system that allows remote users to communicate with peers using video, audio, and gestures. With this research, we explore the use of head-mounted displays and depth sensor cameras to create a system that (1) enables remote users to be immersed in another person's view, and (2) offers a new way of sending and receiving the guidance of an expert through 3D hand gestures. With our system, both users are surrounded in the same physical environment and can perceive real-time inputs from each other.
