Abstract

A method realizing a plurality of keys/buttons which positions are determined dynamically and passively. When a plurality of fingers of a user'"'"'s one or two hand(s) hold or touch a multi-touch pad/screen, a plurality of touch points will be produced. So, a plurality of keys/buttons which positions are determined dynamically and passively can be realized on the multi-touch pad/screen by means of the touch points being regarded as keys/buttons, and the fingers being matched with the keys/buttons one to one via the touch points, and losing and regaining of each of the touch points and its coordinates because of a corresponding finger'"'"'s operation or changing of a coordinate value which represents a finger'"'"'s press force among coordinates of each of the touch points because of a corresponding finger'"'"'s operation being regarded as an operation of a corresponding key/button. After a key/button operation ends, the fingers still hold or touch the touch pad/screen.

Claims

1. A method realizing a plurality of keys/buttons which positions are determined dynamically and passively, when a user'"'"'s one hand'"'"'s or two hands'"'"' multiple fingers hold or touch a multi-touch pad/screen, a plurality of touch points will be produced, and are regarded as keys/buttons,

wherein when all the fingers release and leave the multi-touch pad/screen, make the keys/buttons'"'"' positions pending.

2. The method realizing a plurality of keys/buttons which positions are determined dynamically and passively as claimed in claim 1, wherein a key/button is associated with a finger via a touch point.

3. The method realizing a plurality of keys/buttons which positions are determined dynamically and passively as claimed in claim 1, wherein a position of at least one of the keys/buttons is determined only after a corresponding finger holds or touches the multi-touch pad/screen.

4. The method realizing a plurality of keys/buttons which positions are determined dynamically and passively as claimed in claim 1, wherein losing and regaining of a touch point corresponding to a finger is regarded as an operation of a corresponding key/button.

5. The method realizing a plurality of keys/buttons which positions are determined dynamically and passively as claimed in claim 1, wherein changing of a coordinate value representing a finger'"'"'s press force of a touch point corresponding to a finger is regarded as an operation of a corresponding key/button.

6. The method realizing a plurality of keys/buttons which positions are determined dynamically and passively as claimed in claim 1, wherein after an operation of a key/button ends, a corresponding finger still holds or touches the touch pad/screen.

7. The method realizing a plurality of keys/buttons which positions are determined dynamically and passively as claimed in claim 1, wherein any unused touch point or key/button is ignored.

8. The method realizing a plurality of keys/buttons which positions are determined dynamically and passively as claimed in claim 1, wherein a handheld digital device with a multi-touch function is reformed into a mouse.
