The invention provides a
touch panel function extending
system of an electronic device, a method and an electronic device thereof. The
touch panel function extending
system of the electronic device comprises a
mode switching module, a
signal receiving module, an instruction
database and a calculation identifying module, wherein, the
mode switching module receives a keystoke
signal from a keystoke and ensues that the manipulation state of the electronic device is switched between an ordinary mode and a special mode according to the keystoke
signal; the signal receiving module receives a contact signal from a
touch panel and sends the contact signal to the calculation identifying module; under the special mode, the calculation identifying module reads and knows an
operating instruction according to the fact that the contact signal identifies one of the following of a contact coordinate, a contact frequency and a continuous path; moreover, a signal for calling or executing an
application software or a program installed or stored inside the electronic device is generated corresponding to the
operating instruction following the corresponding relation loaded by the instruction
database. The invention improves the service convenience.
