Abstract

A touch screen panel to input multi-dimension values and a method of controlling the touch screen panel are provided. In the touch screen panel, a touch screen unit displays a multi-dimensional coordinate system, and senses whether a certain point of the multi-dimensional coordinate system is touched, a control unit calculates coordinates of the touched point if the touched point is sensed, and a coordinate display unit displays values of the calculated coordinates.

Claims

1. A touch screen panel to input multi-dimension values, comprising:

a touch screen unit which displays a multi-dimensional coordinate system, and senses a certain point on the multi-dimensional coordinate system that is touched by a user;

a control unit which calculates coordinates of the touched point relative to the multi-dimensional coordinate system; and

a coordinate display unit which provides a visual display of values of the calculated coordinates.

2. The touch screen panel of claim 1, wherein, if the touched point is touched by the user for a period longer than a reference time period, the control unit increases the values of the calculated coordinates corresponding to an amount of time that elapses.

3. The touch screen panel of claim 2, wherein the control unit controls a visual display of the increased values of the coordinates at certain time intervals.

4. The touch screen panel of claim 2, wherein the control unit calculates the increased values of the calculated coordinates by multiplying the values of the calculated coordinates by (N+1) at the certain time intervals, wherein N is a number of times the certain time interval elapses.

5. The touch screen panel of claim 1, wherein the multi-dimensional coordinate system is a multi-dimensional coordinate system comprising a horizontal axis and a vertical axis.

6. The touch screen panel of claim 1, further comprising an image display unit which provides a visual display of an image,

wherein the control unit operates the image display unit to shift and display an image at a location thereof that corresponds to the values of the calculated coordinates.

7. The touch screen panel of claim 1, further comprising a text display unit which provides a visual display of a cursor and text,

wherein the control unit operates the text display unit to display the cursor at a location thereof that corresponds to the calculated coordinates and enable inputting of the text.

8. A method of inputting multi-dimension values in a touch screen panel for displaying a multi-dimensional coordinate system, the method comprising:

sensing a certain point on the multi-dimensional coordinate system that is touched by a user;

calculating coordinates of the touched point relative to the multi-dimensional coordinate system; and

displaying values of the calculated coordinates.

9. The method of claim 8, wherein in the sensing of the certain point, if the touched point is touched by the user for a period longer than a reference time period, the values of the calculated coordinates increases corresponding to an amount of time that elapses.

10. The method of claim 9, wherein the values of the increased coordinates are displayed at certain time intervals.

11. The method of claim 9, wherein in the calculation of the coordinates, the increased values of the calculated coordinates are calculated by multiplying the values of the calculated coordinates by (N+1) at the certain time intervals, wherein N is a number of times the certain time interval elapses.

12. The method of claim 8, wherein the multi-dimensional coordinate system is a multi-dimensional coordinate system comprising a horizontal axis and a vertical axis.

13. The method of claim 8, further comprising shifting and displaying an image at a location that corresponds to values of the calculated coordinates.

14. The method of claim 8, further comprising

displaying a cursor at a location that corresponds to the calculated coordinates and enabling input of text;

and

displaying the input text from at a location of the displayed cursor.

15. A touch screen panel device to receive input by touch, comprising:

an input portion to provide visual display of a coordinate system and to receive selection of a position on the coordinate system by touch input;

an image display portion to provide visual display of a predetermined image at a position thereof corresponding to the selected position on the coordinate system; and

a coordinate display portion to provide visual display of coordinate values of the selected position.

16. The touch screen panel device of claim 15, wherein the touch input determines a plurality of coordinates of the coordinate system by a single touch.

17. The touch screen panel device of claim 15, wherein the coordinate values of the selected position comprises at least two values that are independent of each other.

18. The touch screen panel device of claim 15, further comprising a controller to determine a time duration that elapses while the selection of the position on the coordinate system by touch input occurs to determine accumulated coordinate values of the selected position that corresponds to the amount of time that elapses.

19. The touch screen panel device of claim 15, wherein the input portion comprises a touch screen panel.

20. The touch screen panel device of claim 15, wherein the input portion, the image display portion, and the coordinate display portion are displayed as a single graphic user interface.

22. The method of claim 20, further comprising detecting a time duration that elapses while the selection of the position on the coordinate system by touch input occurs to determine accumulated coordinate values of the selected position that corresponds to the amount of time that elapses.

21. A method of receiving input by touch using a touch screen panel, comprising:

receiving a selection by touch input of a position on a coordinate system displayed on an input portion of the touch screen panel device;

displaying a predetermined image at a position of an image display portion of the a touch screen panel device that corresponds to the selected position on the coordinate system; and

displaying coordinate values of the selected position on a coordinate display portion of the touch screen panel device.
