FUNCTIONAL EXPANSION SYSTEM FOR A TOUCH PAD
First Claim
1. A functional expansion system for a touch pad of an electronic device, which provides a plurality of software and programs and at least a key for inputting an operational instruction, comprising:
- a mode switching module receiving a key pressing signal from the key to switch a controlled status of the electronic device between normal mode and special mode according to the pressing signal;
a signal receiving module connecting with the touch pad to receive a touch signal from the touch pad;
an instruction data base providing a plurality of preset data related to an operational instruction corresponding to a control signal; and
a recognizing and figuring module connecting with the mode switching module, the signal receiving module and the instruction data base respectively, recognizing one of parameters of touch coordinates, touch frequency and continuous locus under the special mode according to the touch signal, reading out the operational instruction and creating the control signal to call or execute an application software or program in the preset data saved in the instruction data base according to relation between the operational instruction and the control signal.

Abstract
A functional expansion system for a touch pad of an electronic device includes a mode switching module, a signal receiving module, an instruction data base and a recognizing and figuring module. The mode switching module receives key pressing signal from the key to switch a controlled status of the electronic device between normal mode and special mode. The signal receiving module receives the touch signal and sends the touch signal to the recognizing and figuring module. The recognizing and figuring module recognizes touch coordinates, touch frequency or continuous locus under the special mode according to the touch signal, reads out the operational instruction and creates a control signal to call or execute an application software or program in the preset data saved in the instruction data base according to relation between the operational instruction and the control signal.
