Abstract

A human input device and a method for supplying power to the same are provided. The human input device includes: at least two input sensors for detecting movement; and a power controller for supplying power to at least one operating input sensor of the input sensors, and for blocking the power supplied to the other input sensor. Therefore, it is possible to reduce power consumption on the human input device including at least two input sensors for detecting movement.

Claims

1. A human input device comprising:

at least two input sensors for detecting movement; and

a power controller for supplying power to at least one operating input sensor of the input sensors, and for blocking power supplied to the other input sensor.

2. The human input device according to claim 1, wherein the power controller further comprises a function of intermittently supplying power to the respective sensors when all of the input sensors do not operate.

3. The human input device according to claim 1, wherein the power controller further comprises a function of intermittently supplying power only to any one of the input sensors when all of the input sensors do not operate.

4. The human input device according to claim 1, wherein the power controller further comprises a function of supplying power only to at least one of the input sensors on the basis of priority when the plurality of sensors operate.

5. The human input device according to claim 1, wherein the input sensors comprise:

a movement sensor for detecting movement; and

a scroll sensor for detecting scroll operation.

6. The human input device according to claim 5, wherein the power controller further comprises a function of intermittently supplying power to the scroll sensor when both of the movement sensor and the scroll sensor do not operate.

7. The human input device according to claim 5, wherein the power controller further comprises a function of intermittently supplying power to the movement sensor when both of the movement sensor and the scroll sensor do not operate.

8. The human input device according to claim 5, wherein the power controller further comprises a function of intermittently supplying power to both of the movement sensor and the scroll sensor when both of the movement sensor and the scroll sensor do not operate.

9. The human input device according to claim 5, wherein the power controller further comprises a function of supplying power only to any one of the movement sensor and the scroll sensor on the basis of priority when both of the movement sensor and the scroll sensor operate.

10. A method for supplying power to a human input device including at least two input sensors for detecting movement, comprising:

determining whether each of the input sensors operates or not; and

controlling power supply by applying the power to at least one operating input sensor of the input sensors, and blocking the power supplied to the other sensor.

11. The method according to claim 10, further comprising intermittently supplying power to each of the input sensors when all of the input sensors do not operate.

12. The method according to claim 10, further comprising intermittently supplying power only to any one of the input sensors when all of the input sensors do not operate.

13. The method according to claim 10, further comprising supplying power only to at least one of the input sensors on the basis of priority when the plurality of input sensors operate.
