Abstract

A miniaturized keyboard clusters character input groups operable by one finger into an integrated single key. It has a keyboard base to hold a plurality of the integrated single keys. Each integrated single key has a touch sensitive pad and is divided into at least one segment. Each segment corresponds to a character. Thus the character input groups operable by one finger are clustered on one integrated single key. The integrated single key can generate different input characters depending on different finger positions. Hence the keyboard may be shrunk, and the number of keys and input error can be reduced.

Claims

1. A miniaturized keyboard comprising a plurality of integrated single keys on a keyboard base, each integrated single key having a touch sensitive pad and being divided into at least one segment, each segment corresponding to a character, each integrated single key clustering input character groups operable by a user'"'"'s finger.

2. The miniaturized keyboard of claim 1, wherein the integrated single key is formed in a bar type according to a moving track of the finger, a plurality of the integrated single keys being arranged in a juxtaposed fashion on the keyboard base.

3. The miniaturized keyboard of claim 1, wherein the integrated single key has a surface which is formed with a special positioning trace to facilitate fast positioning and identifying of the finger.

4. The miniaturized keyboard of claim 1, wherein the integrated single key has a surface which is formed with a jutting edge on one side to facilitate steady operation of the finger.

5. The miniaturized keyboard of claim 1, wherein the integrated single key has an arched surface.

6. The miniaturized keyboard of claim 1 further including a cursor control panel to function as a mouse.

7. The miniaturized keyboard of claim 1, wherein the keyboard base includes a radio transceiver corresponding to a host radio transceiver connecting to a host to establish a wireless link.

8. The miniaturized keyboard of claim 1, wherein the miniaturized keyboard is used on a notebook computer.

9. The miniaturized keyboard of claim 1, wherein each segment corresponds to a character and corresponds to at least one integrated single key character table displayed on a screen of a host.

10. The miniaturized keyboard of claim 1 further including an independent left hand operation base and an independent right hand operation base.

11. The miniaturized keyboard of claim 10, wherein the left hand operation base and the right hand operation base have respectively a coupling element to couple together to form the keyboard base.
