Abstract

A portable electronic device comprises means for generating or receiving a signal indicating that it has been placed in a predetermined position. The portable electronic device is configured upon receiving said signal to enable user interaction with the portable electronic device by a touchless interaction mode. Also disclosed are various arrangements of a peripheral device and a portable electronic device which cooperate to provide a touchless interaction mode—e.g. through transducers and/or processing means being provided in the peripheral device.

Claims

1. A portable electronic device comprising one or more ultrasonic transmitters and/or receivers, said portable electronic device being arranged such that it is operable in a standalone touchless interaction mode and an enhanced touchless interaction mode,

wherein in the standalone touchless interaction mode, the portable electronic device is arranged to determine a user input using only said ultrasonic transmitters and/or receivers of the portable electronic device;

and

in the enhanced touchless interaction mode, the portable electronic device is arranged to cooperate with a peripheral device comprising one or more further transmitters in order to determine the user input using the ultrasonic transmitters and/or receivers of the portable electronic device and the one or more further transmitters of the peripheral device;

wherein the portable electronic device is further arranged to determine when it has been placed in a predetermined position on, near or against the peripheral device and

is configured such that, upon determining that it is in the predetermined position, the portable electronic device carries out data communication with the peripheral device such that they cooperate to enable the enhanced touchless interaction mode.

2. A device as claimed in claim 1 wherein said standalone and enhanced touchless interaction modes comprise the use of ultrasonic signals reflected from an input object to control a function of the portable electronic device.

3. A device as claimed in claim 1 configured to give an indication that the enhanced touchless interaction mode is active.

21. A device as claimed in claim 1 adapted to receive a signal from the peripheral device permitting the enhanced touchless interaction mode.

22. A device as claimed in claim 1 adapted to be woken up by the peripheral device if the peripheral device detects the presence of the portable electronic device.

23. A device as claimed in claim 1 adapted to determine itself when it is in the predetermined position without receiving a signal indicative thereof from an external source.

25. A device as claimed in claim 1 adapted such that some signal processing required for the enhanced touchless interaction mode is carried out by the peripheral device and some signal processing required for the enhanced touchless interaction mode is carried out by the portable electronic device.

4. A system comprising a portable electronic device comprising one or more ultrasonic transmitters and/or receivers, said portable electronic device being arranged such that it is operable in a standalone touchless interaction mode and an enhanced touchless interaction mode,

wherein in the standalone touchless interaction mode, the portable electronic device is arranged to determine a user input using only said ultrasonic transmitters and/or receivers of the portable electronic device;

and

in the enhanced touchless interaction mode, the portable electronic device is arranged to cooperate with a peripheral device comprising one or more further transmitters in order to determine the user input using the ultrasonic transmitters and/or receivers of the portable electronic device and the one or more further transmitters of the peripheral device;

wherein the portable electronic device is further arranged to determine when it has been placed in a predetermined position on, near or against the peripheral device and

is configured such that, upon determining that it is in the predetermined position, the portable electronic device carries out data communication with the peripheral device such that they cooperate to enable the supplemented touchless interaction mode.

5. A system as claimed in claim 4 wherein the peripheral device comprises one or more ultrasonic transmitters and/or receivers.

6. A system as claimed in claim 4 wherein the peripheral device comprises means for providing electrical power to the portable electronic device.

7. A system as claimed in claim 6 comprising a data connection between the portable electronic device and the peripheral device integrated with the means for providing electrical power to the portable electronic device.

8. A system as claimed in claim 4 wherein the portable electronic device and the peripheral device are configured to pass signals between them to enable the enhanced touchless interaction mode.

9. A system as claimed in claim 4 comprising a data communication arrangement between the portable electronic device and the peripheral device.

10. A system as claimed in claim 4 wherein the peripheral device is adapted to carry out at least some signal processing for implementing said enhanced touchless interaction mode.

11. A system as claimed in claim 10 wherein said processing comprises conversion to or from a digital signal.

12. A system as claimed in claim 4 wherein the peripheral device comprises a module arranged to characterize the movement of an input object and a module arranged to provide control signals to the portable electronic device based on said movement characterization.

13. A system as claimed in claim 4 wherein the peripheral device is adapted to share with the portable electronic device digital processing required to convert signals from transmitters provided on either or both devices into control signals to control the portable electronic device.

14. A system as claimed in claim 4 wherein said standalone and enhanced touchless interaction modes comprise the use of ultrasonic signals reflected from an input object to control a function of the portable electronic device.

15. A system as claimed in claim 4 wherein the peripheral device comprises a stand including one or more tubular support elements.

16. A system as claimed in claim 15 comprising at least one polyvinylidene flouride (PVDF) flexible ultrasonic transmitter housed in said tubular support element.

17. A system as claimed in claim 4 wherein the peripheral device comprises a signal generator configured to drive the one or more further transmitters of the peripheral device to transmit a signal to permit the enhanced touchless interaction mode.

18. A system as claimed in claim 4 wherein the peripheral device comprises a module arranged to detect the presence of the portable electronic device in order to wake up the peripheral device.

19. A system as claimed in claim 4 wherein the peripheral device and/or the portable electronic device is configured to give an indication that the standalone touchless interaction mode and/or the enhanced touchless interaction mode is active.

20. A system as claimed in claim 4 wherein the portable electronic device is provided with a module arranged to transmit a signal for receipt by the peripheral device for indicating the proximity and/or location of the portable electronic device with respect to the peripheral device.

24. A system as claimed in claim 4 wherein the portable electronic device is arranged to determine itself when it is in the predetermined position without receiving a signal indicative thereof from an external source.

26. A system as claimed in claim 4 wherein some signal processing required for the enhanced touchless interaction mode is carried out by the peripheral device and some signal processing required for the enhanced touchless interaction mode is carried out by the portable electronic device.

27. A system as claimed in claim 4 wherein the one or more transmitters of the peripheral device are not sufficient on their own to implement a touchless interaction mode.
