Abstract

An input method with a large keyboard table displaying on a small screen employs a cursor controller to display the larger keyboard table on a small screen includes at least the following steps of: determining the position of a cursor on a keyboard table through the position of a finger on the cursor controller; determining the display area of the keyboard table through the position of the cursor on the keyboard table and displaying on a screen; determining movement of the cursor or moving the keyboard table inverse according to the position and moving direction of the cursor, and altering the display area; marking overlapping characters of the keyboard table and the cursor; and depressing to confirm input of the marked characters. Through this method convenience of input operation improves and data entry can be done faster.

Claims

1. An input method with a large keyboard table displaying on a small screen, comprising the steps of;

determining the position of a cursor on a keyboard table through the position of a finger on a cursor controller;

determining a display area of the keyboard table through the position of the cursor on the keyboard table and displaying on a screen;

determining movement of the cursor or moving the keyboard table inverse according to the position and moving direction of the cursor and altering the display area;

marking overlapping characters of the keyboard table and the cursor; and

depressing to confirm input of the marked characters.

2. The input method of claim 1, wherein the cursor controller is a two-stage depression touch-sensitive pad that includes a first stage finger depression to control movement of the finger and a second stage depression to confirm input of a character where the cursor is located or a selected function key.

3. The input method of claim 1, wherein the touch-sensitive pad of the cursor controller controls the cursor on the screen through an absolute coordinate.

4. The input method of claim 1, wherein the screen is smaller than eight inches.

5. The input method of claim 1, wherein the height or the width of the screen is smaller than the height or the width of the complete keyboard table being displayed.

6. The input method of claim 1, wherein the cursor is controlled by the cursor controller and marked by a cursor label on the screen.

7. The input method of claim 1, wherein the cursor is a marked character or function key selected by the cursor controller.

8. The input method of claim 1, wherein the keyboard table is a table or a graphic consisting of a plurality of characters or function keys.

9. The input method of claim 1, wherein the keyboard table is larger than a display area of the screen to be displayed at the same time (in terms of height and width), the screen displaying only a portion of the keyboard table.

10. The input method of claim 1, wherein the keyboard table appears automatically on a display area of the screen when the cursor controller is operated by a user, the keyboard table automatically disappears from the display area of the screen after the cursor controller is not being operated by the user for a selected time period.

11. The input method of claim 1, wherein the step of determining movement of the cursor or moving the keyboard table inverse according to the position and moving direction of the cursor means that the keyboard table is moved inversely on the screen until the display area of the keyboard table displays the cursor and one border of the keyboard table concurrently, then the movement of the keyboard table stops to substitute the movement of the cursor.

12. The input method of claim 1, wherein the step of determining movement of the cursor or moving the keyboard table inverse to alter the display area according to the position and moving direction of the cursor means that the cursor remains still on a selected position on the display area, and the keyboard table is moved inversely on the screen.
