APPARATUS AND METHOD FOR PROCESSING USER INPUT USING MOTION OF OBJECT
First Claim
Patent Images
1. An apparatus for processing a user input, the apparatus comprising:
- a determiner configured to determine that at least one point corresponds to a first mode input instructing the apparatus to track motion of an object, based on an input image comprising the at least one point generated by sensing the motion of the object; and
a processor configured to track the motion of the object, in response to the determiner determining that the at least one point corresponds to the first mode input.

15. A method of processing a user input, the method comprising:
-
obtaining an event signal indicating movement of an object; calculating a centroid of a plurality of pixels included in the event signal; extracting a dominant line included of the plurality of pixels; and recognizing a portion of the object based on the centroid and the dominant line. - View Dependent Claims (16, 17, 18, 28)

19. A user input processing method comprising:
-
obtaining an event signal in which a motion of an object is sensed; dividing a plurality of pixels included in the event signal into a predetermined number of sections; calculating orientation vectors of the plurality of pixels; calculating feature vectors of the sections based on the orientation vectors; and recognizing a portion of the object based on the feature vectors. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 29)
