One Per Cent: Microsoft's MirageTable allows AR teleconferencing: The system, called MirageTable, uses a Kinect sensor to record 3D images of the user, which are then displayed on a curved screen with a 3D projector. This allows users to make virtual copies of real-world objects and interact with them without the need for gloves or other tracking devices. For example, MirageTable lets you make virtual duplicates of a single real-world bowling pin, then knock them down with a virtual ball.
Connecting two MirageTables allows for remote interactions that seem far more real than a simple video conference call. Users at each end can make virtual copies of their real-world objects and manipulate them in a shared environment as if they were sitting across a table from each other.
