Abstract: In accordance with an aspect of the present invention, a device and a method allows for body-based interaction with 3D applications on wall displays. The interface consists of virtual dockable tools which can be unholstered, used to manipulate geometry, and holstered on the user's body. The system also utilizes proprioceptive cues to allow the user to manipulate and holster tools without visual feedback. A 3D depth camera maps 3D user position to 3D coordinates in the virtual scene. Partitioning the physical work space into a region for interaction with geometry, and a region for tool management allows for intuitive mapping between the physical and virtual work space. The system can support multiple users, including simultaneous interaction with the environment, and tool exchange between users.
