Abstract
Techniques for optimizing which LEDs in a HMD to use, the brightness of those LEDs, and camera exposure are divulged based on the particular function to be performed. For instance, one set of optimization parameters may be implemented for eye tracking purposes while a different set of optimization parameters may be implemented for eye-based authentication purposes.
Claims13
A system comprising:
- at least one computer medium that is not a transitory signal and that comprises instructions executable by at least one processor to:
- establish a first set of parameters in a head-mounted device (HMD) for a first function;
- establish a second set of parameters in the HMD for a second function, wherein the parameters comprise at least light source brightness for illuminating an eye of a wearer of the HMD and an identity of which light sources in the HMD to use, and wherein the first function comprises authentication;
- responsive to a demand for eye tracking, illuminate at least a first light source that causes a glint from an eye;
- and
- responsive to a demand for authentication, illuminate at least a second light source that causes no glint from the eye.

An apparatus, comprising:
- at least one processor programmed with instructions to execute A, or B, or both A and B, wherein:
- A comprises responsive to a demand for eye tracking, illuminate at least a first light source that causes a glint from an eye, and responsive to a demand for authentication, illuminate at least a second light source that causes no glint from the eye;
- and wherein
- B comprises responsive to a demand for eye tracking, illuminate at least a first light source with no light diffuser positioned between the light source and an eye, and responsive to a demand for authentication, illuminate at least a second light source with at least one light diffuser positioned between the light source and the eye.
