Abstract

A remote control includes sensing circuitry operable to detect a user touching the remote control. The remote control further includes a light source operable to backlight user input circuitry of the remote control. Control logic of the remote control activates the light source responsive to the sensing circuitry detecting the user touching the remote control.

Claims

1. A remote control comprising:

user input circuitry;

at least one light source operable to backlight the user input circuitry;

sensing circuitry operable to detect a user touching the remote control; and

control logic communicatively coupled to the light source and the sensing circuitry, the control logic operable to activate the light source responsive to the sensing circuitry detecting the user touching the remote control.

2. The remote control of claim 1, wherein the sensing circuitry comprises a capacitive sensor that detects the user touching the remote control.

3. The remote control of claim 1, wherein the sensing circuitry comprises a resistive sensor that detects the user touching the remote control.

4. The remote control of claim 1, wherein the sensing circuitry comprises an accelerometer that detects the user moving the remote control.

5. The remote control of claim 1, wherein the sensing circuitry comprises a mercury switch that detects the user moving the remote control.

6. The remote control of claim 1, wherein the sensing circuitry comprises a gyroscope that detects the user moving the remote control.

7. The remote control of claim 1, wherein the control logic is further operable to deactivate the light source responsive to input from the sensing circuitry indicating that the user is no longer touching the remote control.

8. The remote control of claim 1, wherein the control logic is further operable to deactivate the light source after a specified time period following detection of the user touching the remote control.

9. The remote control of claim 1, wherein the control logic is operable to activate the light source to backlight a portion of the user input circuitry based upon input provided to the user input circuitry by the user.

10. A remote control comprising:

user input circuitry;

at least one light source operable to backlight the user input circuitry;

a light sensor operable to detect an amount of ambient light;

sensing circuitry operable to detect a user touching the remote control; and

control logic communicatively coupled to the light source, the light sensor and the sensing circuitry, the control logic operable to activate the light source responsive to the sensing circuitry detecting the user touching the remote control if the amount of ambient light is below a predetermined threshold.

11. The remote control of claim 10, wherein the sensing circuitry comprises a capacitive sensor that detects the user touching the remote control.

12. The remote control of claim 11, wherein the sensing circuitry comprises a resistive sensor that detects the user touching the remote control.

13. The remote control of claim 10, wherein the sensing circuitry comprises an accelerometer that detects the user moving the remote control.

14. The remote control of claim 10, wherein the sensing circuitry comprises a mercury switch that detects the user moving the remote control.

15. The remote control of claim 10, wherein the sensing circuitry comprises a gyroscope that detects the user moving the remote control.

16. The remote control of claim 10, wherein the control logic is further operable to deactivate the light source responsive to input from the sensing circuitry indicating that the user is no longer touching the remote control.

17. The remote control of claim 10, wherein the control logic is further operable to deactivate the light source after a specified time period following detection of the user touching the remote control.

18. The remote control of claim 10, wherein the control logic is operable to activate the light source to backlight a portion of the user input circuitry based upon input provided to the user input circuitry by the user.

19. A remote control comprising:

a plurality of buttons;

a touch pad;

at least one light source operable to backlight the buttons; and

control logic communicatively coupled to the light source, the buttons and the touch pad, the control logic operable to;

receive user input from the buttons and the touch pad and generate commands for a controlled device based on the user input;

determine whether the user is touching the remote control based upon a signal from the touch pad; and

activate the light source responsive to determining that the user is touching the remote control.

20. The remote control of claim 19, further comprising:

a light sensor operable to detect an amount of ambient light;

wherein the control logic is operable to activate the light source when the user is touching the remote control based further upon a determination that the amount of ambient light is below a specified threshold.
