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.

First claim

What is claimed is:

1. A display apparatus comprising:
a display unit;
a communication unit which is configured to receive information about a user input from an external input device, the user input comprising an input start point and an input end point; and
at least one processor which is configured to process an image including at least one object and a cursor to be displayed on the display unit,
to determine a predicted moving point of the cursor in the image based on the input start point, a moving direction and a moving distance of the user input received from the external input device in the image, and
to move the cursor to a position of the at least one object neighboring the predicted moving point in the image,
wherein the moving distance is a distance between the input start point and the input end point.

2. The display apparatus of claim 1 , wherein the at least one processor calculates a coordinate of the predicted moving point of the cursor in the image based on a moving distance of the cursor between a first input of the input start point and a second input of the input end point and the moving direction of the cursor between the first input and the second input.

3. The display apparatus of claim 2 , wherein the at least one image processor calculates a coordinate of a third point of the predicted moving point based on the first point of the first input and a second point of the second input when the cursor is moved, and based on the third point, if the object is located within a preset radius range based on the third point, 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 same distance from the second point as the moving distance between the first point and the second point on the axis of the cursor in the moving direction.

5. The display apparatus of claim 3 , wherein the at least one 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 at least one image processor decreases a moving speed of the cursor as the cursor approaches the object.

7. The display apparatus of claim 3 , wherein the at least one 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 at least one 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 at least one 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 at least one 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 at least one 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. A display apparatus comprising:
a display unit;
a communication unit which is configured to receive information about a user input from an external input device; and
at least one processor which is configured to process an image including at least one object and a cursor to be displayed on the display unit,
wherein the at least one processor is further configured to determine a predicted moving point of the cursor in the image based on an input start point and a moving direction of the user input received from the external input device in the image, and move the cursor to a position of the at least one object neighboring the predicted moving point in the image, and
wherein the at least one 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 at least one object and a cursor;
receiving user input comprising an input start point and an input end point in the image from the external input device;
determining a predicted moving point of the cursor based on the input start point and a moving direction and a moving distance of the user input in the image; and
moving the cursor to a position of the at least one object neighboring the predicted moving point in the image,
wherein the moving distance is a distance between the input start point and the input end point.

16. The control method of claim 15 , wherein the determining comprises calculating a coordinate of the predicted moving point of the cursor in the image based on the moving distance of the cursor between a first input of the input start point and a second input of the input end point and the moving direction of the cursor between the first input and the second input.

17. The control method of claim 16 , wherein the determining comprises calculating a coordinate of a third point of the predicted moving point based on the first point of the first input and a second point of the second input when the cursor is moved; and
wherein, 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 calculated coordinate of the third point is at same distance from the second point as the distance between the first point and the second point on the axis of the cursor in the moving direction.

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 selec
