Abstract

A display apparatus includes a motion recognition unit which recognizes a movement of an object located outside the display apparatus, a storage unit which stores therein information about the operation corresponding to each motion; and a control unit which divides a movement recognition period using a movement nonrecognition period, determines a motion corresponding to a movement of the object within the movement recognition period, and performs an operation corresponding to the determined motion according to information stored in the storage unit.

Claims

1. A display apparatus, comprising:

a motion recognition unit which recognizes a movement of an object in a motion recognition mode for recognizing the movement of the object around the display apparatus;

a storage unit which stores information about an operation corresponding to each motion; and

a control unit which, if there is the movement of the object, recognizes the movement of the object for a time divided by a preset time interval in the motion recognition mode determines a motion corresponding to the recognized movement, and performs an operation corresponding to the determined motion by using the stored information in the storage unit.

2. The display apparatus of claim 1,

wherein the control unit determines the motion based on the movement of the object in a movement recognition period which is divided by a time interval, wherein the time interval is a movement nonrecognition period where the movement is not recognized.

3. The display apparatus of claim 2, wherein, if the movement is determined to be a moving motion based on the speed of the movement, the control unit extends a size of the movement recognition period during which the moving motion is made, omits the use of the movement nonrecognition period, and moves a pointer on a screen according to a direction of the movement of the moving motion.

4. The display apparatus of claim 2, wherein the control unit determines the movement to be one wave motion, if the object performs a plurality of reciprocating movements in the movement recognition period.

5. The display apparatus of claim 4, wherein the control unit changes a current screen to a previous or upper screen, if the control unit determines the movement to be the wave motion.

6. The display apparatus of claim 2, wherein the control unit determines the movement to be one swing motion, if the object moves with acceleration in one direction in the movement recognition period.

7. The display apparatus of claim 6, wherein the control unit performs an operation of changing a channel or page, if the control unit determines the movement to be the swing motion.

8. The display apparatus of claim 2, wherein the movement nonrecognition period and the movement recognition period have a fixed size.

24. The display apparatus of claim 2, wherein the size of the movement recognition period is a time determined in a range from 1 to 1.5 seconds and the size of the movement nonrecognition period is a time determined in a range from 250 msec to 350 msec.

9. A motion control method of a display apparatus, comprising:

recognizing a movement of an object in a motion recognition mode for recognizing the movement of the object around the display apparatus;

recognizing the movement of the object for a time divided by a preset time interval, if there is the movement of the object in the motion recognition mode, and determining the motion corresponding to the recognized movement; and

performing an operation corresponding to the determined motion.

16. The motion control method of claim 9, wherein the time interval is a movement nonrecognition period where the movement is not recognized and wherein the motion is determined in accordance with the movement of the object during the movement recognition period which is divided by the movement nonrecognition period.

17. The motion control method of claim 16, wherein the determining the motion comprises determining the movement to be a moving motion based on a speed of the movement extending a size of the movement recognition period during which the moving motion is made, and omitting the use of the movement nonrecognition period, and

the performing the operation comprises moving a pointer on a screen according to a direction of the movement of the moving motion.

18. The motion control method of claim 16, wherein the determining the motion comprises determining the movement to be one wave motion, if the object performs a plurality of reciprocating movements in the movement recognition period.

19. The motion control method of claim 18, wherein the performing the operation comprises changing to a previous or upper screen, if the movement is determined to be the wave motion.

20. The motion control method of claim 16, wherein the determining the motion comprises determining the movement to be one swing motion, if the object moves with acceleration in one direction and then stops in the movement recognition period.

21. The motion control method of claim 20, wherein the performing the operation comprises performing an operation of changing a channel or page, if the movement is determined to be the swing motion.

22. The motion control method of claim 16, wherein the movement nonrecognition period and the movement recognition period have a fixed size.

23. The motion control method of claim 22, wherein the size of the movement recognition period is a time determined in a range from 1 to 1.5 seconds and the size of the movement nonrecognition period is a time determined in a range from 250 msec to 350 msec.

10-15. -15. (canceled)

25. An electronic device, comprising:

a motion recognition unit which recognizes a movement of an object in a motion recognition mode for recognizing the movement of the object around the display apparatus;

a storage unit which stores information about an operation corresponding to each motion;

a control unit which, if there is the movement of the object, recognizes the movement of the object for a time divided by a preset time interval in the motion recognition mode, determines a motion corresponding to the recognized movement, and performs an operation corresponding to the determined motion by using the stored information in the storage unity; and

wherein the time interval is a movement nonrecognition period where the movement of the object is not recognized and at least one of the movement recognition period and the movement nonrecognition period may have a variable size.

26. The electronic device of claim 25, wherein the control unit, if the movement of the object is made at a constant speed which is above a preset threshold in the movement recognition period, adjusts a size of the movement recognition period.
