Abstract

A sensor having a rigid connector connectable to an interface device for interfacing with a processing device. The rigid connector is configured to convey information to the interface device, the information identifying a property of the sensor. An interface device connectable to the rigid connector of a sensor and configured to receive information conveyed by the connector, the information identifying a property of the sensor. A method of interfacing a sensor to a processing device. The information conveyed by the connector may identify the ability of the sensor to identify a position in one dimension or to identify a position in two dimensions, or the ability of the sensor to identify manually applied presses or manually applied gestures. The sensor may be a fabric position sensor or a flexible circuit sensor.

Claims

1. A position sensor having a rigid connector connectable to an interface device for interfacing with a processing device, wherein

said connector is configured to convey information to said interface device, said information identifying a property of said sensor.

2. A sensor according to claim 1, wherein said property is the ability of the sensor to identify either one of a position in one dimension and a position in two dimensions.

3. A sensor according to claim 1, wherein said sensor has a fabric sensing area and a fabric communication ribbon.

4. A sensor according to claim 3 wherein:

said connector has a first plurality of terminals each connectable to a conductor of said ribbon;

a second plurality of conductors are present within said ribbon, and said second plurality is less than said first plurality; and

said information is conveyed by the particular selection of terminals that are connected to said conductors.

5. A sensor according to claim 1, wherein said information is conveyed by an identification chip.

6. A sensor according to claim 1, wherein said property is a sensing configuration of said sensing area.

7. A sensor according to claim 1, wherein said property is the ability of said sensor to identify either one of manually applied presses and manually applied gestures.

8. A sensor according to claim 1, wherein said property is either one of that the sensor forms part of a personal item and that the sensor is an audio playback device controller.

9. A sensor according to claim 8, wherein said sensor forms part of a personal item and said personal item is one of a jacket, trousers, a skirt, a shirt, a bag and a rucksack.

10. A method of interfacing a position sensor to a processing device, comprising the steps of:

providing said position sensor with a rigid connector connectable to an interface device for interfacing with said processing device, and

configuring said connector to convey information to said interface device, said information identifying a property of said sensor.

11. A method according to claim 10, wherein said property is the ability of the sensor to identify either one of a position in one dimension and a position in two dimensions.

12. A sensor according to claim 10, wherein said sensor has a fabric sensing area and a fabric communication ribbon.

13. A method according to claim 10, wherein said property is a sensing configuration of said sensor.

14. A method according to claim 10, wherein said property is the ability of said sensor to identify either one of manually applied presses and manually applied gestures.

15. A method according to claim 10, wherein said sensor forms part of an item of clothing.

16. A method according to claim 15, wherein said sensor is removable from said item of clothing.

17. A method according to claim 10, wherein said processing device is one of an audio playback device and a mobile telephone.

18. An interface device, comprising:

a processing circuit with analog ports and control ports; and

a housing, for enclosing said processing circuit and for supporting a first physical interface and a second physical interface;

said first physical interface is connected to said analog ports and is connectable to a rigid connector of a position sensor having a sensing area,

said second physical interface is connected to said control ports and is connectable to an electronic device, such that when connected said interface device allows the electronic device to be controlled by the position sensor, wherein;

said interface device is configured to receive information conveyed by said connector, said information identifying a property of said sensor.

19. An interface device according to claim 18, wherein said processing circuit is a programmable micro-controller and said interface device is pre-programmed with data linking locations within said sensing area to functions of said electronic device.

20. A sensor according to claim 18, wherein said sensor has a fabric sensing area and a fabric communication ribbon.
