GAZE-BASED POWER CONSERVATION FOR PORTABLE MEDIA PLAYERS
First Claim
1. A portable media player with gaze-responsive power conservation comprising:
- a casing configured to be held in a hand of a user;
a processor disposed within the casing;
a visual display affixed to the casing;
an audio display;
a main memory functionally coupled to the processor;
a secondary memory functionally coupled to the processor, the secondary memory having media content retrievably stored therein;
a gaze sensor physically coupled to the casing and functionally coupled to the processor, the gaze sensor configured to transmit signals to the processor responsive to a gaze of a user;
a program operatively loaded into the main memory having instructions executable by the processor to;
present media content to a user by displaying visual content on the visual display and by playing audio content through the audio display;
reduce the power consumption of the visual display by lowering an intensity of display output in response to the gaze sensor indicating that the user is not gazing in the general direction of the visual display, while continuing to play audio content normally to the user through the audio display.

Abstract
A portable media player has a gaze-responsive power conservation feature. The portable media player includes a casing, processor, visual display, audio display, main memory functionally coupled to the processor, and secondary memory functionally coupled to the processor, where the secondary memory has media content retrievably stored therein. A gaze sensor transmits signals to the processor responsive to a gaze of a user. A program has instructions executable by the processor to: (a) present media content to a user by displaying visual content on the visual display and by playing audio content through the audio display; and (b) reduce power consumption of the visual display by lowering an intensity of display output when the gaze sensor indicates the user is not gazing in the general direction of the visual display, while continuing to play audio content to the user through the audio display at a substantially unchanged power level.
