Abstract

A handheld mobile communication apparatus and operating method thereof are disclosed. The handheld mobile communication apparatus includes a touch sensing component, a key, a storage unit and a control unit. The touch sensing component senses a touch, thus generating a touch signal. The storage unit has a first command database and a second command database. The control unit selects the first command database or the second command database according to whether the key is pressed, and generates a control signal corresponding to the touch according to the touch signal and the selected command database.

Claims

1. A handheld mobile communication apparatus, comprising:

a touch sensing component, for sensing a touch to generate a touch signal;

a key;

a storage unit, for storing a first command database and a second command database; and

a control unit, coupled to the touch sensing component, the key and the storage unit, for selecting the first command database or the second command database according to whether the key is pressed, and generating a control signal according to the touch signal and the selected command database.

2. The handheld mobile communication apparatus as claimed in claim 1, wherein the touch sensing component is a touch panel.

3. The handheld mobile communication apparatus as claimed in claim 1, wherein the touch sensing component is a touch pad.

4. The handheld mobile communication apparatus as claimed in claim 1, the touch signal being an analog signal, the handheld mobile communication apparatus further comprising:

an analog-to-digital converter (ADC), coupled to the touch sensing component and the control unit, for converting the touch signal in an analog format to a touch signal in a digital format to generate a digital touch signal, and transmitting the digital touch signal to the control signal.

5. The handheld mobile communication apparatus as claimed in claim 1, wherein the key has a predetermined function, and the control unit further determines duration of a press of the key and performs the predetermined function when the duration is not greater than a threshold.

6. The handheld mobile communication apparatus as claimed in claim 5, wherein the first command database is a predetermined command database, and the control unit selects the second command database when it is determined that the duration is greater than the threshold.

7. A method for operating a handheld mobile communication apparatus comprising a touch sensing component, a key, and a storage unit storing a first command database and a second command database, the method comprising:

generating a touch signal in response to a touch sensed by the touch sensing component;

selecting, as a selected command database, the first command database or the second command database according to whether the key is pressed; and

generating a control signal according to the touch signal and the selected command database.

8. The method as claimed in claim 7, wherein the touch sensing component is a touch panel.

9. The method as claimed in claim 7, wherein the touch sensing component is a touch pad.

10. The method as claimed in claim 7, the touch signal being an analog signal, the method further comprising:

converting the touch signal from an analog format to a digital format.

11. The method as claimed in claim 7, the key having a predetermined function, the method further comprising:

determining duration of a press of the key, and performing the predetermined function when the duration is not greater than a threshold.

12. The method as claimed in claim 11, the first command database being a predetermined command database, the method further comprising:

selecting the second command database when the duration is greater than the threshold.

13. The method as claimed in claim 7, wherein the touch signal respectively corresponds to different control signals in the first command database and the second command database.

14. A handheld mobile communication apparatus, comprising:

a touch unit, for sensing a touch when the touch is generated on the touch unit by an object to generate a touch signal;

a key, for generating a switch signal when the key is pressed; and

a control unit, coupled to the touch unit and the key, for determining whether the switch signal is generated when the touch signal is generated; and

generating a first control signal corresponding to the touch signal when the switch signal is not generated and generating a second control signal corresponding to the touch signal when the switch signal is generated;

wherein, the handheld mobile communication apparatus performs different operations corresponding to the first control signal and the second control signal.

15. The handheld mobile communication apparatus as claimed in claim 14, further comprising:

a storage unit, coupled to the control unit, for storing a first command database and a second command database;

wherein, the control unit selects the first command database or the second command database according to whether the switch signal is generated to correspondingly generate the first control signal or the second control signal.

16. The handheld mobile communication apparatus as claimed in claim 14, wherein the touch unit is a touch panel.

17. The handheld mobile communication apparatus as claimed in claim 14, wherein the touch unit is a touch pad.

18. The handheld mobile communication apparatus as claimed in claim 14, the touch signal being an analog signal, the handheld mobile communication apparatus further comprising:

an ADC, coupled to the touch unit and the control unit, for converting the touch signal in the analog format to a touch signal in a digital format to generate a digital touch signal, and transmitting the digital touch signal to the control signal.

19. The handheld mobile communication apparatus as claimed in claim 14, wherein the key has a predetermined function, and the control unit further determines duration of a press of the key and performs the predetermined function when the duration is not greater than a threshold.

20. The handheld mobile communication apparatus as claimed in claim 19, wherein the first command database is a predetermined command database, and the control unit selects the second command database when it is determined that the duration is greater than the threshold.
