Abstract
A user interaction apparatus using a pattern image includes: an image output unit for outputting a general image on a display region; a laser radiating unit for radiating laser beams for a pattern image; a pattern image forming unit for forming the pattern image by using the laser beams; a pattern image output unit for outputting the pattern image by overlapping the same on the display region of the general image; and an image acquiring unit for capturing the pattern image output on the display region. The apparatus further includes: an image recognizing unit for recognizing a user input by performing an image processing on the pattern image captured by the image acquiring unit.
