Abstract

The invention relates to a communication device (101; 102; 103) for controlling a system is provided, the communication device comprising a reflecting element (111; 112; 113) for composing a system control command, wherein the composed system control command is comprised of light reflected by the reflecting element (111; 112; 113). The invention further relates to a receiver (200) for receiving the system control command composed by and comprised of the light reflected by the reflecting element (101; 102; 103) of the communication device, the receiver comprising a sensing unit (210) for sensing the light reflected by the reflecting element and a processing unit (220) for retrieving the system control command based on the light sensed by the sensing unit (210).

Claims

1. A communication device (101;

102;

103) for controlling a system, the communication device comprising a reflecting element (111;

112;

113) for composing a system control command, wherein the composed system control command is comprised of light reflected by the reflecting element.

2. A communication device (101;

102;

103) as claimed in claim 1 wherein the composed system control command is based on a position of the reflecting element (111;

112;

113).

3. A communication device (101;

102;

103) as claimed in claim 1 wherein the reflecting element (111;

112;

113) comprises a retro-reflective surface.

6. A receiver (200) for receiving a system control command composed by and comprised of light reflected by a reflecting element (111;

112;

113) of a communication device (101;

102;

103) as claimed in claim 1, the receiver (200) comprising;

a sensing unit (210) for sensing the light reflected by the reflecting element; and

a processing unit (220) for retrieving the system control command based on the light sensed by the sensing unit (210).

7. A receiver (200) as claimed in claim 6, wherein the sensing unit 210 is further arranged for obtaining an image (301;

302;

303) based on the light reflected by the reflecting element (111;

112;

113).

8. A receiver (200) as claimed in claim 6, wherein the retrieved system control command is based on the light sensed by the sensing unit (210) at a plurality of time instances.

9. A receiver (200) as claimed in claim 6 further comprising a light source (230) for emitting light to be reflected by the reflecting element (111;

112;

113) of the communication device (101;

102;

103).

4. A communication device (101;

102;

103) further comprising a shape determining means (141;

142;

151;

152) for determining a shape of the reflecting element.

5. A communication device (101;

102;

103) further comprising an identifier (161) for identifying the communication device.

10. A method (800) of controlling a system, the method comprising:

a composing step (810) for composing a system control command, wherein the composed system control command is comprised of light reflected by a reflecting element of a communication device;

a sensing step (820) for sensing the light reflected by the reflecting element; and

a processing step (830) for retrieving the system control command based on the light sensed in the sensing step (820).

11. A computer program product to be loaded by a computer arrangement, the computer program product comprising instructions for controlling a system, the computer arrangement comprising a processing unit and a memory, the computer program product, after being loaded, providing said processing unit with the capability of retrieving a system control command composed by a reflecting element (111;

112;

113) of a communication device (101;

102;

103) based on a light sensed by a sensing unit of a receiver (200).
