APPARATUS FOR TOUCHING PROJECTION OF 3D IMAGES ON INFRARED SCREEN USING SINGLE-INFRARED CAMERA
First Claim
1. An apparatus for touching a projection of a 3d image on an infrared screen using a single-infrared camera, comprising:
- an infrared Light Emitting Diode (LED) array for generating an infrared screen in a space by emitting infrared rays;
a projector for projecting an image on the infrared screen;
a single infrared camera disposed above or under the center portion of the infrared LED array such that a lens faces the infrared screen; and
a spatial touch recognition module for calculating the X-axial and Z-axial coordinates on the infrared screen touched by a user indication object, using an image photographed by the infrared camera.

Abstract
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.
