Abstract

A keyboard with automatic adjusting key intervals can adjust the key interval values and the key frame edge values of a keyboard according to the detected contour scope of a user'"'"'s hands. The adjusted keyboard is displayed on a touch screen so that the user can perform keyboard operation more smoothly on the keyboard that matches the size of his/her hands.

Claims

1. A keyboard having automatic adjusting key intervals allowing a keyboard display type to be adjusted according to a detected size of a user'"'"'s hands, the keyboard comprising:

a detection module for measuring and obtaining a contour scope of the user'"'"'s hands;

an adjustment module for adjusting a display value of the keyboard according to the contour scope; and

a display module to determine the keyboard display type according to the display value and display the keyboard.

2. The keyboard of claim 1, wherein the contour scope is the coordinate values of X and Y axes of the outmost boundary of the user'"'"'s hands.

3. The keyboard of claim 1, wherein the detection module includes an optical sensing circuit to obtain the contour scope of the user'"'"'s hands.

4. The keyboard of claim 1, wherein the detection module includes a pressure sensing circuit to obtain the contour scope of the user'"'"'s hands.

5. The keyboard of claim 1, wherein the display value is a key interval value.

6. The keyboard of claim 1, wherein the display value is a key frame edge value.

7. The keyboard of claim 1 further including an actuation module to activate the detection module.

8. The keyboard of claim 1 further including a storing module for storing a plurality of keyboards that have varying key interval values and key frame edge values.

9. The keyboard of claim 8, wherein the storing module further stores the key interval values and the key frame edge intervals that have been adjusted by the adjustment module.

10. The keyboard of claim 1, wherein the display module is a touch screen.

11. A method for automatically adjusting key intervals to adjust a keyboard display type according to a detected size of a user'"'"'s hands, the method comprising the steps of:

measuring the user'"'"'s hands;

obtaining a contour scope of the hands;

adjusting a display value according to the contour scope; and

determining and displaying the display type according to the display value.

12. The method of claim 11, wherein the measuring the user'"'"'s hands is processed by an optical sensing approach.

13. The method of claim 11, wherein the measuring the user'"'"'s hands is processed by a pressure sensing approach.

14. The method of claim 11, wherein the contour scope is the coordinate values of X and Y axes of the outmost boundary of the user'"'"'s hands.

15. The method of claim 11, wherein the display value is a key interval value.

16. The method of claim 11, wherein the display value is a key frame edge value.

17. The method of claim 11, wherein the adjusting a display value is processed according to a proportional shrinking approach.

18. The method of claim 11, wherein the adjusting a display value is processed by accessing a preset value.
