First Claim
Patent Images
1. An apparatus for controlling a user interface, the apparatus comprising:
- a reception unit to receive an image of a user from a sensor;
a detection unit to detect a position of a face of the user, and a position of a hand of the user, from the received image;
a processing unit to calculate a difference between the position of the face and the position of the hand; and
a control unit to start sound recognition corresponding to the user when the calculated difference is less than a threshold value, and to control a user interface based on the sound recognition.

Abstract
An apparatus and method for controlling a user interface using sound recognition are provided. The apparatus and method may detect a position of a hand of a user from an image of the user, and may determine a point in time for starting and terminating the sound recognition, thereby precisely classifying the point in time for starting the sound recognition and the point in time for terminating the sound recognition without a separate device. Also, the user may control the user interface intuitively and conveniently.
