30 Claims

1. A processor-based Extended Reality (XR) device, comprising:

a processor; and

an eye blink detection circuit communicatively coupled to the processor;

the processor configured to:

apply a default power profile;

detect, using the eye blink detection circuit, an eye close event of a user of the processor-based XR device indicating a start of an eye blink window having a duration of no more than 400 milliseconds; and

responsive to detecting the eye close event and during the eye blink window:

select a test power profile from a plurality of power profiles;

apply the test power profile;

measure an operating characteristic of the processor-based XR device;

compare the operating characteristic with a corresponding reference range; and

update the test power profile based on the comparing;

wherein each power profile of the plurality of power profiles specifies one or more of a system setting, an option, and an attribute affecting power usage of the processor-based XR device.
