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.
