Abstract
Techniques related to eye tracking using reverse-biased light-emitting diode (LED) devices are disclosed. In some embodiments, a viewing apparatus comprises a reverse-biased LED device that is positioned within a field-of-view of an eye. The reverse-biased LED device receives light reflected from the eye and generates signal based on the received light. The generated signal is used to determine a position of the eye.
Claims20
A method comprising:
- receiving, at a reverse-biased light-emitting diode (LED) device of a viewing apparatus, light reflected from an eye, the reverse-biased LED device being positioned within a field-of-view of the eye;
- generating, at the reverse-biased LED device, a signal based on the received light;
- and
- causing determination of a position of the eye based on the generated signal.
