PROJECTION IMAGE TOUCH DEVICE OF A SINGLE INFRARED RAY CAMERA MODE FOR PROCESSING A COMMAND OF A USER BASED ON A TOUCH POSITION

摘要

PURPOSE: A projection image touch device of a single infrared ray camera mode is provided to supply an interactive UI(User Interface) to users and to supply fun and convenience to the users.;CONSTITUTION: An infrared ray LED(Light Emitting Diode) array(110) illuminates infrared rays and generates an infrared ray screen on a space. A projector projects an image on the infrared ray screen. A single infrared ray camera(120) includes a lens toward the infrared ray screen and is installed in the upper side or the lower side of a center unit of the infrared ray LED array. A space touch recognition module calculates an X/Z-axis coordinate of the infrared ray screen, which is touched by a user indication unit, using an image photographed by the infrared ray camera. When a pulse signal is inputted from a pulse generation unit(180), an LED driving unit(190) blocks DC power supply of the infrared ray LED array.;COPYRIGHT KIPO 2013;[Reference numerals] (120) Infrared ray camera; (137) Display module; (150) Space touch recognition module; (160) Computing module; (180) Pulse generation unit; (190) LED driving unit; (200) DC power; (210) Resistance
