Abstract
An extension device is applied to an electronic device with a touch interface. The extension device includes an input unit, a sensing unit and a processing unit. The sensing unit connects to the touch interface and is coupled to the input unit. The processing unit includes a detecting area disposed on the touch interface corresponding to the sensing unit. When an external force is applied to the input unit, the sensing unit is relatively enabled to output a signal, and the processing unit receives the signal and transforms the signal into an execute instruction.
Claims10
An extension device applied to an electronic device, wherein the electronic device comprises a touch interface, the extension device comprising:
- an input unit;
- a sensing unit connecting to the touch interface and coupled to the input unit;
- and
- a processing unit comprising a detecting area disposed on the touch interface corresponding to the sensing unit;
- wherein, when an external force is applied to the input unit, the sensing unit is relatively enabled to output a signal, and the processing unit receives the signal and transforms the signal into an execute instruction.
An extension device applied to an electronic device, wherein the electronic device comprises a touch interface, the extension device comprising:
- an input unit;
- a constant-frequency sensing unit connecting to the touch interface and coupled to the input unit for outputting a constant-frequency signal;
- an encoding sensing unit connecting to the touch interface and coupled to the input unit for outputting an encoded signal;
- and
- a processing unit comprising a detecting area disposed on the touch interface corresponding to the constant-frequency sensing unit and the encoding-sensing unit;
- wherein, when an external force is applied to the input unit, the constant-frequency sensing unit and the encoding sensing unit are relatively enabled to output the constant-frequency signal and the encoded signal, respectively, and the processing unit receives the constant-frequency signal and the encoded signal and transforms them into an execute instruction.
