Abstract

A method and apparatus is provided for entering alphanumeric characters into a computing device. A user selects a row in a character array containing a plurality of alphanumeric characters using a first input device and selects a character in the row using a second user input device. A processor outputs the selected character to a display or to memory. The selected row may, in some embodiments, be displayed to the user on a display screen.

Claims

1. A device for entering alphanumeric characters into a computing device, said device comprising:

a housing;

a display disposed on a front face of the housing;

a first user input device, disposed adjacent a left or right edge of the display, for receiving user selection of a row in a character array containing a plurality of alphanumeric characters;

a second user input device, disposed adjacent a bottom edge of the display, for receiving user selection of an alphanumeric character in a row of said character array selected by a user via the first user in put device; and

a processor to output the selected character responsive to user input received via the second user input device.

2. The device of claim 1 wherein the processor is configured to display the selected row on said display responsive to user input received via the first user input device.

3. The device of claim 2 wherein the display comprises a touch screen display and wherein the touch screen display also functions as the second user input device for receiving user selection of a character in a selected row.

4. The device of claim 2 wherein the processor is configured to change the appearance of the selected character on said display responsive to user input received via the second input device to indicate the user selection of a character.

5. The device of claim 4 wherein the processor is configured to highlight the selected character to indicate the user selection of a character.

6. The device of claim 4 wherein the processor is configured to change the size of the selected character to indicate the user selection of a character.

7. The device of claim 1 wherein the second user input device comprises one of an input key, a pointing device, a touch-sensitive input, and an optical input.

15. The device of claim 1 wherein the first user input device comprises either a wheel or a pair of push buttons disposed on a side of the housing adjacent the left or right edge of the display.

16. The device of claim 15, wherein the wheel or pair of push buttons is disposed at a vertical position on said side of the housing proximal to a top edge of the display.

8. A method of inputting text into a computing device having a housing and a display disposed on a front face of the housing, comprising:

receiving a first user input at a first input device, disposed adjacent a left or right edge of the display, indicating a user selection of a row in a character array containing a plurality of alphanumeric characters;

receiving a second user input at a second input device, disposed adjacent a bottom edge of the display, indicating user selection of an alphanumeric character in a row of said character array selected by a user via the first user input device; and

outputting the selected character responsive to second user input.

9. The method of claim 8 further comprising displaying the selected row of said character array on said display responsive to said first user input.

10. The method of claim 9 wherein the display comprises a touch screen display and wherein receiving a second user input indicating user selection of an alphanumeric character comprises receiving a touch input via said touch screen display.

11. The method of claim 9 further comprising changing an appearance of the selected character on said display responsive to said second user input to indicate the user selection of a character.

12. The method of claim 11 wherein changing an appearance of the selected character on said display comprises highlighting the selected character.

13. The method of claim 11 wherein changing an appearance of the selected character on said display comprises changing the size of the selected character.

14. The method of claim 8 wherein the second user input is received via one of an input key, a pointing device, a touch-sensitive input, and an optical input.

18. The method of claim 8 wherein the first user input is received via either a wheel or a pair of push buttons disposed on a side of the housing adjacent the left or right edge of the display.

19. The method of claim 18 wherein the wheel or pair of push buttons is disposed at a vertical position on said side of the housing proximal to a top edge of the display.

20. The method of claim 8, wherein the first user input is received via a set of input keys arranged on the front face of the housing along the left or right edge of the display.

17. The device of claim I wherein the first user input device comprises a set of input keys arranged on the front face of the housing along the left or right edge of the display.
