Abstract

A display apparatus, an input apparatus, and a method for compensating coordinates using the same. A method for compensating coordinates using a display apparatus includes receiving movement information from an input apparatus, calculating a coordinate value based on the movement information, and displaying a cursor on the calculated coordinate value. When a button selection command is received from the input apparatus, replacing a coordinate value calculated after receiving the button selection command with a coordinate value of a stable position calculated before receiving the button selection command, and displaying the cursor on the replaced coordinate value, and manipulating an item on which the cursor is located according to the button selection command. Accordingly, the user may locate a cursor on the location that the user wants and execute a display item.

receiving movement information and transmitting, by an input apparatus, the received movement information to a display apparatus;

calculating, by the display apparatus, a coordinate value based on the received movement information;

displaying a cursor on the calculated coordinate value;

in response to receiving a button selection command, compensating, by the display apparatus, a coordinate value calculated after receiving the button selection command;

displaying the cursor on the compensated coordinate value; and

manipulating an item on which the cursor is located based on the button selection command.

2. The method as claimed in claim 1, wherein said compensating comprises compensating the calculated coordinate value to a coordinate value of a stable position in which no change of the calculated coordinate value exists during a predetermined period of time before receiving the button selection command.

3. The method as claimed in claim 1, wherein said compensating comprises when a button selection command is received from the input apparatus while the cursor is located on an item and when the coordinate value calculated after receiving the button selection command is outside a location of the item, compensating the coordinate value to be within the item if the coordinate value is in a stable position and within the item before said receiving of the button selection command.

4. The method as claimed in claim 1, wherein the displaying comprises:

additionally compensating the coordinate value calculated after receiving the button selection command according to an instantaneous speed of movements of the input apparatus; and

displaying the cursor compensated by said additional compensating.

5. The method as claimed in claim 4, wherein said additional compensating comprises, when the instantaneous speed is higher than a first predetermined value, displaying the cursor by reflecting the coordinate value calculated after receiving the button selection command, and when the instantaneous speed is lower than the second predetermined value, compensating the coordinate value calculated after receiving the button selection command to the previously calculated coordinate value.

6. The method as claimed in claim 5, wherein said additional compensating comprises, when the instantaneous speed is higher than the second predetermined value and lower than the first predetermined value, adding a weighted value according to the instantaneous speed and compensating the calculated coordinate value.

7. The method as claimed in claim 1, wherein the compensating further comprises:

determining whether the button selection command is a click command or a drag command by determining at least one of a period of time when the button selection command is received and the change amount of the coordinate value calculated during the receiving of the button selection command.

8. The method as claimed in claim 7, the determining comprises, when the period of time the button selection command is received is lower than a predetermined period of time, or when the period of time when the button selection command is received is higher than a predetermined period of time, and when the change amount of the calculated coordinate value during receiving the command is lower than a predetermined value, determining the button selection command as a click command.

9. The method as claimed in claim 7, the determining comprises, when the period of time the button selection command is received is higher than a predetermined period of time, and when the change amount of the calculated coordinate value during receiving the command is higher than a predetermined value, determining the button selection command as a drag command.

10. The method as claimed in claim 7, the manipulating comprises, when the button selection command is a click command, executing an item on which the cursor is located, and when the button selection command is a drag command, moving the item on which the cursor is located along manipulation of the input apparatus.

11. The method as claimed in claim 1, wherein the input apparatus is an input apparatus of an absolute mapping method which displays a coordinate value at a location pointed by the input apparatus.

12. A display apparatus comprising:

a display configured to display at least one of a cursor and an item;

a communicator configured to communicate with an external input apparatus; and

a controller configured to calculate a coordinate value based on movement information of the input apparatus received through the communicator, configured to control the display to display the cursor on the calculated coordinate value, and when a button selection command is received from the input apparatus through the communicator, configured to compensate a coordinate value calculated after receiving the button selection command and configured to control the display to display the cursor on the replaced coordinate value.

13. The display apparatus as claimed in claim 12, wherein the controller compensates the calculated coordinate value to a coordinate value of a stable position in which no change to the calculated coordinate value exists during a predetermined period of time before receiving the button selection command.

14. The display apparatus as claimed in claim 12, wherein the controller, when a button selection command is received from the input apparatus while the cursor is located on an item and the coordinate value calculated after receiving the button selection command is outside a location of the item, compensates the coordinate value to be within the item if the coordinate value is in a stable position within the location of the item before receiving the button selection command.

15. The display apparatus as claimed in claim 12, wherein the controller controls the display to additionally compensate the coordinate value calculated after receiving the button selection command according to an instantaneous speed of movements of the input apparatus and controls the display to display a cursor on the additionally compensated coordinate value.

16. The display apparatus as claimed in claim 15, wherein the controller, when the instantaneous speed is higher than a first predetermined value, displays the cursor by reflecting the coordinate value calculated after receiving the button selection command, and when the instantaneous speed is lower than a second predetermined value, compensates the coordinate value calculated after receiving the button selection command to the previously calculated coordinate value.

17. The display apparatus as claimed in claim 16, wherein the controller, when the instantaneous speed is higher than the second predetermined value and lower than the first predetermined value, adds a weighted value according to the instantaneous speed and compensates the calculated coordinate value.

18. The display apparatus as claimed in claim 12, wherein the controller determines whether the button selection command is a click command or a drag command by determining at least one of a period of time when the button selection command is received and the change amount of the coordinate value calculated during receiving the button selection command.
