Abstract

An input device having a touch pad that senses a touch of a finger for selectively providing plural types of instructions for a coupled apparatus includes a finger type recognition unit for recognizing a finger type of a finger that is sensed by the touch pad and an instruction output unit for outputting the instruction according to the finger type recognized by the finger type recognition unit.

Claims

1. An input device having a touch pad that senses a touch of a finger for selectively providing plural types of instructions for a coupled apparatus, the input device comprising:

a finger type recognition unit for recognizing a finger type of the finger that is sensed by the touch pad; and

an instruction output unit for outputting at least one of the plural types of the instructions according to the finger type recognized by the finger type recognition unit.

2. The input device as in claim 1 further comprising:

a touch position detection unit for detecting a position of a touch on the touch pad,

wherein the instruction output unit outputs at least one of the plural types of the instructions according to the position to the touch detected by the touch position detection unit in association with the finger type recognized by the finger type recognition unit.

3. The input device as in claim 1,

wherein the touch pad is disposed separately from a display unit that displays an operational condition of the apparatus.

4. The input device as in claim 1,

wherein the touch pad is disposed integrally on a top of the display unit that displays an operational condition of the apparatus.

5. The input device as in claim 1,

wherein the finger type recognition unit recognizes the finger type of the finger that is sensed by the touch pad based on a detection of a fingerprint of the finger.

6. The input device as in claim 1,

wherein the finger type recognition unit recognizes the finger type of the finger that is sensed by the touch pad based on a detection of a shape of a hand projected onto the touch pad when the touch is sensed by the touch pad.

7. The input device as in claim 1,

wherein the apparatus is a car navigation system.

8. The input device as in claim 1,

wherein the apparatus is a personal computer.

9. A method for providing plural types of instructions for a coupled apparatus based on a touch of a finger on a touch pad comprising:

detecting a finger type of the finger based on the touch on the touch pad; and

associating the finger type detected by the touch pad with the instruction,

wherein at least one of the plural types of the instructions in association with the finger type detected by the touch pad is provided for the coupled apparatus.

10. The method as in claim 9 further comprising:

detecting a position of the touch on the touch pad,

wherein at least one of the plural types of the instructions is provided for the coupled apparatus based on the finger type detected by the touch pad and the position of the touch.

11. The method as in claim 9,

wherein the finger type is detected based on a fingerprint sensed by the touch pad.

12. The method as in claim 9,

wherein the finger type is detected based on a shape of a hand sensed by the touch pad.

13. The method as in claim 9,

wherein the coupled apparatus is a car navigation system.

14. The method as in claim 9,

wherein the coupled apparatus is a personal computer.
