Abstract

An earpiece includes an earpiece housing, a processor disposed within the earpiece housing, and a gesture based interface operatively connected to the processor and configured to detect changes in an energy field associated with user gestures. The processor is configured to interpret the changes in the energy field to determine the user gestures.

Claims

1. A method for near field gesture based control of an earpiece the method comprising:

emitting pulses at a first sampling rate from at least one emitter of the earpiece;

sensing the pulses reflected off a user of the earpiece, the sensing performed by at least one detector of the earpiece;

increasing from the first sampling rate to a second sampling rate higher than the first sampling rate, the pulses from the at least one emitter if proximity of the user relative to the at least one emitter is above a first threshold;

determining by a processor of the earpiece an occurrence of a gesture performed by the user of the earpiece based on the pulses reflected off the user as detected by the at least one detector during performance of the gesture.

2. The method of claim 1 wherein the at least one emitter is an optical emitter and wherein the at least one detector is an optical detector.

3. The method of claim 1 wherein the at least one emitter comprises at least one infrared (IR) light emitting diode (LED).

4. The method of claim 1 wherein the at least one emitter comprises at least two infrared (IR) light emitting diodes (LEDs).

5. The method of claim 4 wherein the detector comprises at least one IR receiver.

6. The method of claim 1 wherein the at least one emitter comprises at least one ultra sound emitter.

7. The method of claim 1 wherein the at least one emitter comprises a plurality of ultra sound emitters.

8. The method of claim 1 wherein the user gesture is a swipe gesture.

9. The method of claim 8 wherein the processor of the earpiece is configured to determine a directionality of the swipe gesture from a peak proximity of the user gesture.

10. The method of claim 8 wherein the earpiece further comprises a speaker operatively connected to the processor and wherein the processor is further configured to provide audio feedback to a user through the speaker if a confidence level associated with the peak proximity of the swipe gesture is below a second threshold.

11. The method of claim 10 where the audio feedback further comprises an additional request associated with the swipe gesture.

12. The method of claim 1 wherein the processor is further configured to reverse modes when the pulses sensed by the detector exceed a threshold.

13. The method of claim 1 wherein the processor is configured to alter a rate of energy emission upon detection of an object.

14. The method of claim 1 wherein the earpiece housing is water impervious to allow a user to swim while wearing the earpiece.

15. The method of claim 1 wherein the at least one emitter comprises a plurality of radar emitters.

16. The method of claim 1, wherein the detector further comprises at least one radar receiver.

17. The method of claim 1 wherein the user gesture is a tap gesture.
