Abstract

A light spot control system, using a projection light of a projection device to initiate a control of a mobile communication device, includes an I/O unit and a processing unit. The I/O unit is used to receive the projection light. The processing unit is used to provide a time value and a position value. The time value is a duration of the projection light stayed at the I/O unit, and the position value is a position of the projection light stayed at the I/O unit. When the time value meets a default value, the respective position value is used to perform the control.

Claims

1. A light spot control system for a mobile communication device, using a projection light of a projection device, comprising:

an I/O unit for receiving a projection light, the projection light used to initiate a control of the mobile communication device; and

a processing unit for providing a time value and a position value, the time value being a duration of the projection light stayed at the I/O unit, the position value being a position of the projection light stayed at the I/O unit;

wherein, when the time value meets a default value, the respective position value is used to drive the control.

2. The light spot control system according to claim 1, wherein said mobile communication device is a mobile phone.

3. The light spot control system according to claim 1, wherein said projection device is a laser beam device.

4. The light spot control system according to claim 1, wherein said projection light is a laser beam.

5. The light spot control system according to claim 1, wherein said I/O unit includes a light detector and a screen.

6. The light spot control system according to claim 1, wherein said processing unit is a micro control chip.

7. A light spot control method, applicable to a mobile communication device, using a projection light of a projection device, comprising steps of:

defining an I/O unit for receiving a projection light to the mobile communication device, the I/O unit receiving the projection light to initiate a control of the mobile communication device; and

defining a processing unit to the mobile communication device, the processing unit providing a time value and a position value, which the time value and the position value are respectively the duration and the location of the projection light stays at the I/O unit;

wherein, when the time value meets a default value, the respective position value is used to drive the control.

8. The light spot control method according to claim 7, wherein said mobile communication device is a mobile phone.

9. The light spot control method according to claim 7, wherein said projection device is a laser beam device.

10. The light spot control method according to claim 7, wherein said projection light is a laser beam.

11. The light spot control method according to claim 7, wherein said I/O unit includes a light detector and a screen.

12. The light spot control method according to claim 7, wherein said processing unit is a micro control chip.
