APPARATUS FOR TOUCHING PROJECTION OF 3D IMAGES ON INFRARED SCREEN USING SINGLE-INFRARED CAMERA

摘要

The present invention relates to an apparatus for touching a projection of a 3D image on an infrared screen using a single-infrared camera, and more specifically to an apparatus for touching a projection of a 3D image, which projects an image in a free space; recognizes a position touched by a user on the projected image and thus can process an order from a user on the basis of the recognized touched position. The present invention can provide tangible and interactive user interfaces to users. In particular, it is possible to implement various UIs (User Interface), in comparison to an apparatus for touching a projection of a 2D image of the related art, by using the Z-axial coordinate on the infrared screen as the information on depth.
