USER INTERFACE DEVICE AND METHOD FOR RECOGNIZING USER INTERACTION USING SAME

摘要

A user interface device includes a frame replacement unit configured to replace a frame of an input image signal by a pattern frame at a frame time; a projector module configured to project an image of the image signal with the pattern frame onto a target; an image acquisition unit configured to capture a pattern image of the pattern frame from the image projected onto the target; and an image recognition unit configured to recognize a user interaction by using the captured pattern image.
