Abstract

A portable electronic device comprising a housing, and a first user interface, a second user interface and one or more sensors supported by the housing, and a method thereof. The first user interface has an active state, and the second user interface has an inactive state while the first user interface is in the active state. The sensor or sensors detect an environmental condition. The second user interface changes from the inactive state to the active state and the first user interface changes from the active state to the inactive state in response to one or more sensors detecting the environmental condition. For another embodiment, the device may detect an energy level of a power source of the portable electronic device. The second user interface of the portable electronic device is then activated and the first user interface of the portable electronic device is deactivated in response to detecting the energy level of the power source.

Claims

1. A portable electronic device comprising:

a housing;

a touch-sensitive screen;

a first touch-sensitive screen technology sub-system for the touch-sensitive screen supported by the housing, the first touch-sensitive screen technology sub-system having an active state and an inactive state;

a second touch-sensitive screen technology sub-system for the touch-sensitive screen supported by the housing, the second touch-sensitive screen technology sub-system having an inactive state and an active state, wherein the second touch-sensitive screen is in the inactive state while the first touch-sensitive screen technology sub-system is in the active state; and

at least one sensor supported by the housing, the at least one sensor detecting a predetermined environmental condition,

wherein the second touch-sensitive screen technology sub-system changes from the inactive state to the active state and the first touch-sensitive screen technology sub-system changes from the active state to the inactive state in response to the at least one sensor detecting the predetermined environmental condition, and

wherein the second touch-sensitive screen technology sub-system has better sensitivity than the first touch-sensitive screen technology sub-system under the predetermined environmental condition.

2. The portable electronic device of claim 1, wherein the predetermined environmental condition is associated, at least in part, with an environment external to the housing.

3. The portable electronic device of claim 1, wherein:

the first and second touch-sensitive screen technology sub-systems are substantially parallel to each other; and

at least a portion of the first touch-sensitive screen technology sub-system overlaps at least a portion of the second touch-sensitive screen technology sub-system.

4. The portable electronic device of claim 1, wherein the second touch-sensitive screen technology sub-system changes from the inactive state to the active state and the first touch-sensitive screen technology sub-system changes from the active state to the inactive state in response to at least one operation mode of the portable electronic device as well as the predetermined environmental condition detected by the at least one sensor.

5. The portable electronic device of claim 1, wherein each of the first and second touch-sensitive screen technology sub-systems is an input component effective to detect user input.

6. The portable electronic device of claim 1, wherein the touch-sensitive screen is an output component effective to provide audio, visual or multimedia output.

7. The method of claim 1, wherein the first touch-sensitive screen technology sub-system comprises one or more of a capacitive sensor, a temperature sensor, or a resistive sensor, and wherein the second touch-sensitive screen technology sub-system comprises one or more of a capacitive sensor, a temperature sensor, or a resistive sensor.

8. A method comprising:

determining that a first touch-sensitive screen technology sub-system for a touch-sensitive screen of a portable electronic device is active while a second touch-sensitive screen technology sub-system for the touch-sensitive screen of the portable electronic device is inactive;

detecting a predetermined environmental condition by at least one sensor of the portable electronic device; and

activating the second touch-sensitive screen technology sub-system of the portable electronic device and deactivating the first touch-sensitive screen technology sub-system of the portable electronic device in response to detecting the predetermined environmental condition by the at least one sensor, wherein the second touch-sensitive screen technology sub-system provides a different sensitivity level than the first touch-sensitive screen technology sub-system under the predetermined environmental condition.

9. The method of claim 8, wherein the predetermined environmental condition is associated, at least in part, with an environment external to a housing of the portable electronic device.

10. The method of claim 8, wherein:

the first and second touch-sensitive screen technology sub-systems are substantially parallel to each other; and

at least a portion of the first touch-sensitive screen technology sub-system overlaps at least a portion of the second touch-sensitive screen technology sub-system.

11. The method of claim 8, wherein activating the second touch-sensitive screen technology sub-system of the portable electronic device and deactivating the first touch-sensitive screen technology sub-system of the portable electronic device includes activating the second touch-sensitive screen technology sub-system of the portable electronic device and deactivating the first touch-sensitive screen technology sub-system of the portable electronic device in response to at least one operation mode of the portable electronic device as well as the predetermined environmental condition detected by the at least one sensor.

12. The method of claim 8, wherein each of the first and second touch-sensitive screen technology sub-systems is an input component effective to detect user input.

13. The method of claim 8, wherein the touch-sensitive screen is an output component effective to provide audio, visual or multimedia output.

14. A method comprising:

activating a first touch-sensitive screen technology sub-system of a touch-sensitive screen of a portable electronic device while a second touch-sensitive screen technology sub-system for the touch-sensitive screen of the portable electronic device is inactive;

detecting an energy level of a power source of the portable electronic device; and

activating the second touch-sensitive user interface of the portable electronic device and deactivating the first touch-sensitive screen technology sub-system of the portable electronic device in response to determining that the energy level of the power source is below a threshold level of energy, wherein the second touch-sensitive screen technology sub-system requires less power than the first touch-sensitive screen technology sub-system.

15. The method of claim 14, wherein each of the first and second touch-sensitive screen technology sub-systems is an input component effective to detect user input.

16. The method of claim 14, wherein the touch-sensitive screen is an output component effective to provide audio, visual or multimedia output.

17. The method of claim 14, wherein the first touch-sensitive screen technology sub-system comprises one or more of a capacitive sensor, a temperature sensor, or a resistive sensor, and wherein the second touch-sensitive screen technology sub-system comprises one or more of a capacitive sensor, a temperature sensor, or a resistive sensor.
