Abstract

We present two methods for the binary detection of gaze for use in near-to-eye displays that can significantly reduce power consumption by turning off the display when the user is not actively viewing the device. A single infrared (IR) emitter-detector pair is used to detect IR reflected from the eye in order to estimate gaze and can reduce the power consumed by the display by over 75%. The first method presented is more configurable and adaptive but requires continuous polling of an analog sensor. The second method is interrupt driven and, except for calibration, the sensor IC is not polled by the host processor.
