Abstract

An electronic device includes a housing, a user interface, and one or more processors operable with the user interface. At least one proximity sensor component is operable with the one or more processors and can include an infrared signal receiver to receive an infrared emission from an object external to the housing. The one or more processors can be operable to actuate one or more user interface devices when the infrared signal receiver receives the infrared emission from an object external to the housing. The actuation can be a function of distance, in accordance with a prioritization, or combinations thereof.

Claims

1. An electronic device, comprising:

a housing;

a user interface;

one or more processors operable with the user interface;

a plurality of user interface devices; and

at least one proximity sensor component operable with the one or more processors and comprising an infrared signal receiver receiving an infrared emission from an object external to the housing;

the one or more processors;

prioritizing the plurality of user interface devices;

actuating a first user interface device after the infrared signal receiver receives the infrared emission from the object and when the object is a first distance from the housing; and

actuating a second user interface device when the object is a second distance from the housing, the second distance less than the first distance.

2. The electronic device of claim 1, the plurality of user interface devices comprising a motion detector.

3. The electronic device of claim 2, the one or more processors actuating the motion detector by transitioning the motion detector from a low power or sleep mode to an active mode of operation.

4. The electronic device of claim 3, the one or more processors actuating only the motion detector after the infrared signal receiver receives the infrared emission from the object.

5. The electronic device of claim 1, the plurality of user interface devices further comprising a microphone.

6. The electronic device of claim 1, wherein the at least one proximity sensor component and associated circuitry of the at least one proximity sensor component comprise the only sensor device operating in an active mode prior to the infrared signal receiver receiving the infrared emission from the object.

7. The electronic device of claim 1, the one or more processors further determining, with the at least one proximity sensor component, a distance of the object from the housing, the one or more processors actuating one or more user interface devices as a function of the distance.

8. The electronic device of claim 1, the first distance being about ten feet.

9. The electronic device of claim 1, the first user interface device comprising an accelerometer, the second user interface device comprising a display.

10. The electronic device of claim 1, the one or more processors actuating a third user interface device when the object is a third distance from the housing, the third distance less than the second distance.

11. The electronic device of claim 10, the first user interface device comprising one or more of an accelerometer or a microphone, the third user interface device comprising a display.

12. The electronic device of claim 1, the one or more processors causing the one or more processors and the user interface to enter a low power or sleep mode when the infrared signal receiver is not receiving the infrared emission.

13. The electronic device of claim 12, the at least one proximity sensor component remaining operational while the one or more processors and the user interface is in the low power or sleep mode.

14. A method in an electronic device, the method comprising:

determining, with at least one proximity sensor component comprising an infrared signal receiver to receive an infrared emission from an object external to a housing, a proximity of the object to the electronic device; and

in response to detecting the proximity of the object, transitioning one or more user interface devices of the electronic device from a low-power or sleep mode to an active mode of operation;

the one or more user interface devices comprising a plurality of user interface devices, the method further comprising actuating some user interface devices before other user interface devices.

15. The method of claim 14, the method further comprising determining a distance of the object to the electronic device.

16. The method of claim 15, the transitioning occurring as a function of the distance.

17. The method of claim 14, the some user interface devices comprising one or more of an accelerator or a microphone, the other user interface devices comprising one or more of a display or a touch sensor.

18. The method of claim 14, further comprising causing the one or more user interface devices to enter a low power or sleep mode when the at least one proximity sensor component fails to detect the proximity of the object.
