Using eye detection for providing control and power management of electronic devices
First Claim
1. A control system for a device comprising:
- an imager and eye detection processing for detecting light received by said imager from a human eye, said eye detection processing being configured to generate an output indicative of determinations of detecting said human eye; and
a controller enabled to switch said device among a plurality of power consumption states in response to said output of said eye detection processing, said controller being configured to execute both of a first conditional response and a second conditional response, wherein(a) said first conditional response is one in which said device is switched from a power-up state to a lower power consumption state upon passage of a first time period without detecting a human eye; and
(b) said second conditional response is one in which said device is switched to said power-up state upon detection of a human eye, said controller including a control algorithm which adaptively adjusts said first time period on a basis of factors that include historical data of occurrences of switching by said controller.

Abstract
Eye detection is used as the basis for providing power management or other variations of operational parameters of a controlled device. The system includes an imager and eye detection processing which cooperate to detect light received from a person'"'"'s eye. The eye detection processing generates an output that can be used for determinations regarding presence of one or more persons or presence of a specific person. This output is used as the basis for switching the controlled device between at least two power consumption states. Eye detection may also be used to allow a person to actively adjust operational conditions of the controlled device, since unnatural eye blinking patterns may be associated with particular commands.

16. A control System for a device comprising:
-
an imager and eye detection processing for detecting light received by said imager from a human eye, said eye detection processing being configured to generate an output indicative of determinations of detecting said human eye, said imager being sampled in a non-continuous basis, with a sampling frequency selected to conserve battery charge; and a controller enabled to switch said device among a plurality of power consumption states in response to said output of said eye detection processing, said controller being configured to execute both of a first conditional response and a second conditional response, wherein (a) said first conditional response is one in which said device is switched from a power-up state to a lower power consumption state upon passage of a first time period without detecting a human eye; and (b) said second conditional response is one in which said device is switched to said power-up state upon detection of a human eye, said controller including a control algorithm which adaptively adjusts said first time period on a basis of factors that include historical data of occurrences of switching by said controller.
