Abstract
Disclosed herein is a 3D space touch apparatus. The 3D space touch apparatus includes a support, an infrared LED array, left and right infrared cameras, and a space touch sensor module. The support supports the infrared LED array and the left and right infrared cameras. The infrared LED array emits infrared rays, which form an infrared screen in a space above the support. The left and right infrared cameras are disposed on the left and right sides of the support so that the lenses thereof can be oriented to the infrared screen. The space touch sensor module calculates the X-, Y- and Z-axis coordinates of a location of the infrared screen, touched by user pointing means, using images captured by the left and right infrared cameras and information about the resolutions and angles of view of the left and right infrared cameras.
