Abstract

Disclosed herein is a method for controlling a touchscreen by using a virtual trackball. The method for controlling the touchscreen includes the steps of displaying a virtual keyboard on the input window, displaying a virtual trackball by selecting an Execute button on the virtual keyboard, enlarging a cursor displayed on the output window and a predetermined region surrounding the cursor, and inputting movement information of the cursor being enlarged and displayed by using the virtual trackball.

Claims

1. As a method for controlling a touchscreen displaying text and a cursor on an output window, after differentiating an input window from an output window within the touchscreen, the method for controlling the touchscreen comprises:

displaying a virtual keyboard on the input window;

displaying a virtual trackball by selecting an Execute button on the virtual keyboard;

enlarging a cursor displayed on the output window and a predetermined region surrounding the cursor; and

inputting movement information of the cursor being enlarged and displayed by using the virtual trackball.

2. The method of claim 1, wherein the enlarging a cursor displayed on the output window and a predetermined region surrounding the cursor further comprises:

enlarging and displaying a virtual trackball of the input window.

3. The method of claim 2, wherein a user is capable of arbitrarily setting up a size of the virtual trackball being enlarged and displayed or sizes of the cursor and the surrounding region of the cursor both being enlarged and displayed.

4. The method of claim 1, further comprising:

having the user select an Enlarged Mode configured to enlarge and display a predetermined region of the output window.

5. The method of claim 4, wherein, in the enlarging a cursor displayed on the output window and a predetermined region surrounding the cursor, the Enlarged Mode is executed, in case the Execute button displayed on the virtual keyboard is selected for more than a predetermined period of time, or in case the Execute button is selected for more than a predetermined number of times, or in case a separate Select button is selected, when the Execute button has been selected.

6. The method of claim 1, wherein the virtual trackball is displayed on the input window in a region surrounding the Execute button.

7. The method of claim 1, wherein the movement information comprises movement direction information indicating a direction along which the cursor is being moved, and button information of the virtual trackball being used, when the cursor is moved.

8. The method of claim 7, wherein the movement direction information includes up, down, left, and right directions.

9. The method of claim 1, further comprising:

displaying the virtual trackball on the virtual keyboard, in case the virtual keyboard is being executed by a mouse input device, the mouse input device corresponding to a security program.
