Abstract

This invention is related to a touch interpretive architecture of multi-fingers gesture to trigger an application program and a touch interpretive method thereof used in the same for interpreting a multi-fingers gesture applied to a touch pad and then acquiring some hot-key messages of at least an application program so as to trigger the application program according to the hot-key messages.

Claims

1. A multitouch contact responsive system comprising:

a touch input interface comprising a touch pad configured to generate a multi-finger gesture operation message in response to a multi-finger gesture performed on the touch pad, the touch pad including a touch sensor;

a hot-key database having multiple pre-stored hot-key messages corresponding to different hot-key functions of an application software program; and

an interpreter unit for interpreting the multi-finger gesture operation message to obtain an interpretive result, retrieving one of the hot-key messages from the hot-key database based on the interpretive result, and outputting an application program control packet including the one of the hot-key messages to an operation system;

wherein the hot-key database and the interpreter unit are in the operation system;

wherein in response to the application program control packet, a behavior control instruction is generated from the operation system to trigger a software object of the application software program to result in a corresponding behavior.

2. The system as claimed in claim 1 further comprising:

a control unit communicating with the touch input interface for receiving the multi-finger gesture operation message, the control unit adapted to output a driving control signal in response to the multi-finger gesture operation message, wherein the control unit includes a driver executed for controlling an instruction set of the touch input interface; and

a system call unit communicating with the control unit for generating a system call instruction in response to the driving control signal.

3. The system as claimed in claim 1, wherein the multi-finger gesture includes a multi-fingers movement operation, a multi-finger rotation operation, a multi-fingers zoom in/out operation or a multi-fingers tapping operation.

4. The system as claimed in claim 2, wherein the system call unit includes a system interface and control module having a plurality of system calls.

5. The system as claimed in claim 1, wherein the interpreter unit comprises:

an interpreting program; and

an interpreting interface and control module serving as an interface of the interpreting

program.

6. A multitouch contact responsive method to control the operation of an application software program, the method comprising steps of:

generating a multi-finger gesture operation message based on a multi-finger gesture performed on a touch pad;

providing a hot-key database having multiple pre-stored hot-key messages corresponding to different hot-key functions of an application software program;

interpreting the multi-finger gesture operation message to obtain an interpretive result;

retrieving one of the multiple hot-key messages from the hot-key database based on the interpretive result; and

outputting an application program control packet including the one of the hot-key message to an operation system,

wherein the hot-key database is in an operation system, and

wherein in response to the application program control packet, a behavior control instruction is generated from the operation system to trigger a software object of the application software program to result in a corresponding behavior.

7. The method as claimed in claim 6, wherein the multi-finger gesture includes a multi-fingers movement operation, a multi-finger rotation operation, a multi-fingers zoom in/out operation or a multi-fingers tapping operation.

8. The method as claimed in claim 6, further comprising:

pre-storing the multiple hot-key messages in the hot-key database before the steps of generating, interpreting, retrieving and triggering.
