First Claim
Patent Images
1. A user interface device comprising:
- 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.

15. A user interface device comprising:
-
a projector module configured to project an image onto a target; a pattern image generator configured to generate a laser beam having a pattern through diffraction to project a pattern image thereof onto the target; an image acquisition unit, in synchronization with the projection of the pattern image, configured to capture the pattern image projected onto the target on which the image is projected; and an image recognition unit configured to recognize a user interaction by using the captured pattern image. - View Dependent Claims (16, 17, 18, 19)
