AR Tabletop Interface Using an Optical See-Through HMD

We propose a user interface that superimposes a virtual touch panel on a flat surface using an optical see-through head-mounted display and an RGB-D camera. The user can use the interface in a hands-free state, and can perform the operation with both hands. The interface performs markerless superimposition of virtual objects on a real scene. In addition, the interface can recognize three-dimensional information of the user's fingers, allowing the user to operate with the virtual touch panel. We developed some applications in which the user can perform various operations on the virtual touch panel.
