Backlighting remote controls

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 wherein the control logic is further operable to deactivate the light source after a first specified time period following detection of the user touching the remote control when an input is not received via the user input circuitry and deactivate the light source after a second specified time period when the input is received via the user input circuitry during the first specified time period wherein the second specified time period is shorter than the first specified time period.

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 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.

9. 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, wherein the sensing circuitry comprises a capacitive sensor that detects the user touching the remote control, the capacitive sensor comprising:

at least one positive electrode;

a plurality of negative electrodes;

at least one dielectric material that separates the at least one positive electrode from the plurality of negative electrodes; and

at least one overlay that covers at least a portion of the at least one positive electrode, at least a portion of the plurality of negative electrodes and at least a portion of the at least one dielectric material; 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.

10. The remote control of claim 9 , 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.

11. The remote control of claim 9 , 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.

12. The remote control of claim 9 , 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.

13. 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;

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

deactivate the light source after a first specified time period following detection of the user touching the remote control when an input is not received via at least one of the buttons or the touch pad; and

deactivate the light source after a second specified time period when the input is received via the at least one of the buttons or the touch pad during the first specified time period wherein the second specified time period is shorter than the first specified time period.

14. The remote control of claim 13 , 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.
