Abstract

Devices and methods are disclosed which relate to an electronic device having a human stimulus receptor which, when activated, suspends activation of a screensaver. The screensaver is activated to conserve the power and life of the electronic device. When latently viewing the electronic device, however, the human stimulus receptor is activated. A countdown starts counting down a pre-determined amount of time once the human stimulus receptor is inactive. At the expiration of the countdown, the screensaver is activated. The human stimulus receptor responds to skin conductivity, natural muscular twitch, pulse, skin temperature, and/or eye movement. Only when the electronic device no longer detects any of these human stimuli will the countdown begin. A user may set the predetermined amount of time.

Claims

1. A portable electronic device comprising:

a processor; and

a memory in communication with the processor, the memory storing instructions that are executed by the processor to perform operations comprising;

starting a first timer upon receiving a first human stimulus at a first human stimulus receptor in communication with the processor,

starting a second timer upon receiving a second human stimulus at a second human stimulus receptor in communication with the processor, wherein the second timer is greater than the first timer, and

activating a screen saver upon expiration of both the first timer and the second timer.

2. The device of claim 1, wherein the first human stimulus receptor is a two-way capacitive transducer.

3. The device of claim 1, wherein the first human stimulus receptor is coupled with one or more of a keyboard, a screen, or a housing of the electronic device.

4. The device of claim 1, further comprising one or more of a laptop, a personal digital assistant, a cellular telephone, or a digital music player.

5. The device in claim 1, wherein the second human stimulus receptor is an input device.

6. The device of claim 5, wherein the operations further comprise receiving a selection of a function of the first human stimulus receptor and the second human stimulus receptor.

7. An electronic device comprising:

a processor; and

a memory in communication with the processor, the memory storing instructions that, when executed by the processor, cause the processor to perform operations comprising;

instructing a power supply in communication with the processor to suspend powering a screen in communication with the processor upon expiration of a first period of time after receiving a first human stimulus from a first human stimulus receptor, and after a second period of time after receiving a second human stimulus from a second human stimulus receptor,

wherein the first period of time is greater than the second period of time.

8. The device of claim 7, wherein the first human stimulus receptor is a two-way capacitive transducer.

9. The device of claim 7, wherein the first human stimulus receptor is coupled with one of a keyboard, the screen, or a housing of the electronic device.

10. The device of claim 7, further comprising one or more of a laptop, a personal digital assistant, a cellular telephone, or a digital music player.

11. The device of claim 7, wherein the second human stimulus receptor is an input device.

12. The device of claim 11, wherein the operations further comprise receiving a selection of a function of the first human stimulus receptor and the second human stimulus receptor.

13. A method comprising:

determining, by a mobile device comprising a processor, a first period of time after receiving a first input at a first input device coupled to the mobile device;

determining, processor, a second period of time after receiving a second input at a second input device coupled to the mobile device; and

activating, by the processor, a screensaver after expiration of both the first period of time and the second period of time;

wherein the first period of time is greater than the second period of time.

14. The method of claim 13, further comprising maintaining suspension of screensaver activation until both the first period of time and the second period of time expire.

15. The method of claim 13, further comprising de-activating the screensaver upon reception of an input.

16. The method of claim 13, further comprising activating the screensaver upon determining that no input is received for a pre-determined amount of time.

17. The method of claim 13, wherein the input comprises one or more of a natural muscular twitch, a temperature, a pulse, or an eye movement.

18. The method of claim 13, further comprising resetting the first period of time and the second period of time.
