Abstract

Simple gestures such as stroking or tapping of a surface (10) can be used to control common functions of electronic systems (16) by positioning one or more sensors (12) on the surface and detecting sounds generated by the interaction with the surface. Signals corresponding to detected sounds are filtered and interpreted either in the system to be controlled or else in the sensors themselves. The direction of movement of a hand (18) stroking the surface can be interpreted as a command to increase or decrease a parameter, such as the sound volume level of a television, for example. Determination of the position of the user'"'"'s hand is unnecessary. The apparatus is therefore simple, inexpensive, robust and discrete, requiring only a minimum of installation and without being necessarily dedicated to a particular electronic system to be controlled.

Claims

1. Control apparatus for controlling an electronic system (16), the apparatus comprising;

a sensor (12) for mounting on or proximate to a surface (10), wherein the sensor includes a microphone for detecting sounds caused by physical interaction with the surface; and

translation means for translating sounds detected by the microphone into one or more commands recognizable by the system,

such that physical interaction with the surface is arranged to control the operation of the system.

2. Control apparatus according to claim 1 wherein the translation means comprises one or more software modules within the system to be controlled.

3. Control apparatus according to claim 1 wherein the translation means is located within the sensor.

4. Control apparatus according to claim 1 wherein the sensor comprises an electronic processor.

5. Control apparatus according to claim 1 comprising a plurality of sensors (12, 20).

6. Control apparatus according to claim 1 wherein the or each sensor comprises an indicator for providing an acknowledgement that the system is being controlled.

7. Control apparatus according to claim 6 wherein the indicator comprises a loud speaker.

8. Control apparatus according to claim 7 wherein the loudspeaker comprises the microphone.

9. A method of controlling an electronic system, the method comprising physically interacting with a surface to generate sounds which are electronically detected and translated into commands recognizable by the system.

10. A method according to claim 9 comprising stroking or tapping a surface.
