Abstract

A display apparatus including: a display unit; a communication unit which receives information about a coordinate from an input device; and an image processor which displays an image including an object and a cursor on the display unit, and moves the cursor toward the object according to a position of the object in the image with respect to information about movement corresponding to a first input coordinate at an input start point and a second input coordinate at an input termination point, wherein the first input coordinate and the second input coordinate are received from the input device through the communication unit.

Claims

1. A display apparatus comprising:

a display unit;

a communication unit which receives information about a coordinate from an input device; and

an image processor which displays an image including an object and a cursor on the display unit, and moves the cursor toward the object according to a position of the object in the image with respect to information about movement corresponding to a first input coordinate at an input start point and a second input coordinate at an input termination point, wherein the first input coordinate and the second input coordinate are received from the input device through the communication unit.

2. The display apparatus of claim 1, wherein the information about movement corresponds to information about moving the cursor from a first point to a second point, and includes a moving distance of the cursor between the first input coordinate and the second input coordinate and a moving direction of the cursor between the first input coordinate and the second input coordinate.

3. The display apparatus of claim 2, wherein the image processor calculates a coordinate of a third point based on the information about movement when the cursor is moved, and based on the third point, if the object is located within a preset radius range, the image processor moves the cursor to the object.

4. The display apparatus of claim 3, wherein the coordinate of the third point is calculated to be in a same direction as the moving direction of the cursor as the cursor moves from the first point to the second point and at a multiple of the moving distance of the cursor.

5. The display apparatus of claim 3, wherein the image processor moves the cursor to the third point if the object is not located within the radius range.

6. The display apparatus of claim 3, wherein the image processor controls a moving speed of the cursor to decrease gradually as the cursor approaches the object.

7. The display apparatus of claim 3, wherein the image processor moves the cursor to a fourth point positioned on an axis in the moving direction of the cursor if the object is not located within the radius range.

8. The display apparatus of claim 7, wherein the image processor moves the cursor to the object if the object is located within the radius range based on a point on the axis in the moving direction of the cursor while the cursor moves to the fourth point.

9. The display apparatus of claim 7, wherein the image processor stops the cursor if an instruction to stop the cursor is received by the communication unit while the cursor moves to the fourth point.

10. The display apparatus of claim 7, wherein the image processor moves the cursor to a fifth point if an instruction to move the cursor to the fifth point is received to the communication unit while the cursor moves to the fourth point.

11. The display apparatus of claim 3, wherein the image processor selects one of a plurality of objects based on a direction of the cursor as the cursor moves and moves the cursor to the selected one of the plurality of objects if the plurality of objects is located within the radius range.

12. The display apparatus of claim 11, wherein the image processor forms an ellipse having the third point as a focus and selects the one of the plurality of objects, the plurality of objects being included in the ellipse, from among the plurality of objects within the radius range.

13. The display apparatus of claim 12, wherein a major axis of the ellipse is positioned on an axis in the moving direction of the cursor.

14. The display apparatus of claim 1, wherein the object comprises a hyperlink of a webpage, or an icon that is selective or executable.

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

displaying an image including an object and a cursor;

receiving a first input coordinate at an input start point and a second input coordinate at an input termination point; and

moving the cursor toward the object according to a position of the object in the image with respect to information about movement corresponding to the first input coordinate and the second input coordinate.

16. The control method of claim 15, wherein the information about movement corresponds to a moving distance of the cursor between the first input coordinate and the second input coordinate and a moving direction of the cursor between the first input coordinate and the second input coordinate.

17. The control method of claim 16, wherein the moving the cursor toward the object comprises:

calculating a coordinate of a third point based on the information about movement when the cursor is moved; and

if the object is located within a preset radius range based on the third point, moving the cursor to the object.

18. The control method of claim 17, wherein the calculating the coordinate of the third point comprises calculating the coordinate of the third point to be in a same direction as the moving direction of the cursor as the cursor moves from a first point to a second point and at a multiple of the moving distance of the cursor.

19. The control method of claim 17, wherein the moving the cursor toward the object further comprises moving the cursor to the third point if the object is not located within the radius range

20. The control method of claim 17, wherein the moving the cursor toward the object further comprises moving the cursor to a fourth point positioned on an axis in the moving direction of the cursor if the object is not located within the radius range.

21. The control method of claim 20, wherein the moving the cursor to the fourth point positioned on the axis in the moving direction of the cursor comprises moving the cursor to the object if the object is located within the radius range based on a point on the axis in the moving direction of the cursor while the cursor moves to the fourth point.

22. The control method of claim 17, wherein the moving the cursor to the object comprises:

selecting one of a plurality of objects based on a direction of the cursor as the cursor moves if the plurality of objects is located within the radius range; and

moving the cursor to the selected one of the plurality of objects.

23. The control method of claim 22, wherein the selecting one of the plurality of objects based on the direction of the cursor as the cursor moves comprises forming an ellipse having the third point as a focus;

and selecting the one of the plurality of objects, the plurality of objects being included in the ellipse, from among the plurality of objects within the radius range.

24. The control method of claim 23, wherein the ellipse has a preset area and a major axis of the ellipse is positioned on an axis in the moving direction of the cursor.

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

displaying an image including an object and a cursor;

receiving an input signal from a user, the input corresponding to a drag motion;

moving the cursor from a first point to a second point;

determining a motion vector based on the received input signal, the first point and the second point;

determining a third point based on the determined motion vector;

if the object is within a predetermined radius of the third point, moving the cursor to a location corresponding to the object; and

if the object is within the predetermined radius of the third point, displaying the cursor as the cursor moves from the first point to the second point and from the second point to the object.

26. The control method of claim 25, further comprising:

if the object is not within the predetermined radius of the third point, moving the cursor to the third point; and

if the object is not within the predetermined radius of the third point, displaying the cursor as the cursor moves from the first point to the second point and from the second point to the third point.
