VIRTUAL EXPANSION KEYBOARD FOR BEING RAYED TO THE OUTSIDE BY USING A BEAM PROJECTOR IN A TERMINAL

摘要

PURPOSE: A virtual expansion keyboard is provided to enabling the using of a keyboard of a small terminal as a keyboard of a computer.;CONSTITUTION: A coordinate analysis unit(150) analyzes a keyboard coordinate through a motion recognition unit. A coordinate input unit inputs the analyzed coordinate in a terminal. A coordinate output unit(170) reads and outputs the inputted coordinate. A projection unit(120) is executed by using a beam projector in the terminal. A keyboard image is included in the beam projector. A motion recognition unit(130) includes a camera photographing unit which photographs selected movement of the keyboard image.;COPYRIGHT KIPO 2013;[Reference numerals] (120) Projection unit; (130) Motion recognition unit; (140) Camera photographing unit; (150) Coordinate analysis unit; (160) Coordinate recognition unit; (170) Coordinate output unit
