Abstract

A display apparatus is provided. The display apparatus includes a communicator configured to communicate with an input apparatus comprising a touch pad, and receive coordinate data corresponding to a dragging trajectory input through the touch pad. The display apparatus also includes a display configured to display the dragging trajectory on a screen based on the received coordinate data; and a controller configured to recognize a number or character corresponding to the dragging trajectory based on the received coordinate data, and provide visual feedback adjusting the displayed dragging trajectory according to a recognition result.

Claims

1. A display apparatus, comprising:

a communicator configured to communicate with an input apparatus comprising a touch pad, and receive coordinate data corresponding to a dragging trajectory input through the touch pad;

a display configured to display the dragging trajectory on a screen based on the received coordinate data; and

a controller configured to recognize a number or character corresponding to the dragging trajectory based on the received coordinate data, and provide visual feedback adjusting the displayed dragging trajectory according to a recognition result.

2. The display apparatus as claimed in claim 1, wherein the controller is further configured to provide different visual feedback when the dragging trajectory is recognized as the character or number, and when the dragging trajectory is not recognized as the character or number.

3. The display apparatus as claimed in claim 2, wherein the controller is further configured to gradually reduce the displayed size of the dragging trajectory, and sequentially move a display location of the dragging trajectory on the screen in response to the dragging trajectory being recognized as the character or number.

4. The display apparatus as claimed in claim 3, wherein the controller is further configured to display the dragging trajectory at a final location at which the dragging trajectory is displayed in a preset font form.

5. The display apparatus as claimed in claim 2, wherein the controller is further configured to provide a graphic effect in a form in which the displayed dragging trajectory gradually disappears dispersedly in response to the dragging trajectory not recognized as the character or number.

6. The display apparatus as claimed in claim 1, wherein the controller is further configured to perform a preset function based on the recognized character or number in response to the dragging trajectory being recognized as the character or number.

7. The display apparatus as claimed in claim 6, wherein the preset function includes at least one from among a channel change, a character input, a menu execution, a mode change, and a volume adjustment.

8. An input apparatus, comprising:

a communicator configured to perform communication with a display apparatus;

a sensor configured to sense a touch operation input on a touch pad; and

a controller configured to calculate coordinate data corresponding to a dragging trajectory in response to a location touched on the touch pad being dragged, and control the transmitting of the calculated coordinate data to the display apparatus.

9. The input apparatus as claimed in claim 8, wherein the controller is further configured to calculate, within a preset time, the coordinate data corresponding to the dragging trajectory from a first point at which a first touch is made to a second point at which a touch is completed.

10. The input apparatus as claimed in claim 8, wherein the input apparatus is a remote control apparatus configured to remotely control the display apparatus.

11. A method of controlling a display apparatus, the method comprising:

performing communication with an input apparatus;

receiving coordinate data that corresponds to a dragging trajectory that is input on a touch pad provided in the input apparatus;

displaying the dragging trajectory on a screen of the display apparatus based on the coordinate data;

recognizing and generating a recognition result of at least one of a character and number corresponding to the dragging trajectory based on the received coordinate data; and

providing visual feedback corresponding to the displayed dragging trajectory based on the recognition result.

12. The method as claimed in claim 11, wherein the providing of the visual feedback includes providing different visual feedback when the dragging trajectory is either recognized as the character or number and when the dragging trajectory is not recognized as the character or number.

13. The method as claimed in claim 12, wherein the providing of the visual feedback further includes gradually reducing the displayed size of the dragging trajectory, and sequentially moving a display location in response to the dragging trajectory being recognized as the character or number.

14. The method as claimed in claim 13, wherein the providing of the visual feedback further includes displaying the dragging trajectory at a final location at which the dragging trajectory is displayed in a preset font form.

15. The method as claimed in claim 12, wherein the providing of the visual feedback further includes providing a graphic effect in a form in which the displayed dragging trajectory gradually disappears dispersedly in response to the dragging trajectory not being recognized as the character or number.

16. The method as claimed in claim 11, wherein the method further comprises:

performing a preset function based on the recognized character or number in response to the dragging trajectory being recognized as the character or number.

17. A method of controlling an input apparatus that performs communication with a display apparatus, the method comprising:

sensing a touch operation input on a touch pad;

calculating coordinate data corresponding to a dragging trajectory in response to a location touched on the touch pad being dragged; and

transmitting the calculated coordinate data to the display apparatus.

18. The method as claimed in claim 17, wherein the calculating of the coordinate data further includes calculating, within a preset time, the coordinate data corresponding to the dragging trajectory from a first point in which a first touch is made to a second point in which a touch is completed.

19. A touch input display system comprising:

an input device configured to receive a touch input and calculate a path of the touch input comprising;

a touch pad configured to receive the touch input;

a processor configured to calculate the path along the touch pad taken by the touch input; and

a transmitter configured to transmit the path; and

a display device comprising;

a screen configured to display the received path from the input device; and

a controller configured to detect if a character or number is present in the path,

wherein the screen is further configured to transition from displaying the path to displaying visual feedback.

20. The touch input display system of claim 19, wherein the visual feedback includes at least one of displaying using a specific font format, at a specific size, at a specific location on the screen, and a gradual disappearance of the path.
