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.
Claims20
A system comprising:
- a memory comprising computer-executable instructions;
- and
- a processor configured to access the memory and execute the computer-executable instructions to perform operations comprising:
- establish a first set of parameters in a head-mounted device (HMD) for a first function;
- and
- establish a second set of parameters in the HMD for a second function, wherein the first set of parameters and the second set of parameters comprise at least a light source 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.

An apparatus comprising:
- a memory comprising computer-executable instructions;
- and
- a processor configured to access the memory and execute the computer-executable instructions to perform operations comprising:
- identify parameters for a headset for an authentication test;
- determine for the parameters whether iris-pupil contrast as detected from one or more images from one or more cameras of the headset satisfies a first test;
- responsive to iris-pupil contrast failing to satisfy the first test, modify one or more parameters and re-determining whether iris-pupil contrast satisfies the first test;
- determine whether iris-sclera contrast satisfies a second test;
- responsive to iris-sclera contrast failing to satisfy the second test, modify one or more parameters and re-determining whether iris-sclera contrast satisfies the second test;
- determine whether iris sharpness satisfies a third test;
- responsive to iris sharpness failing to satisfy the third test, modify one or more parameters and re-determining whether iris sharpness satisfies the third test;
- and
- responsive to the first, second, and third tests being satisfied, use a current set of parameters to conduct authentication of a user.
9 more elements
A computer-implemented method comprising:
- executing A, or B, or A and B, wherein:
- A comprises:
- responsive to a demand for eye tracking, illuminating at least a first light source that causes a glint from an eye;
- and
- responsive to a demand for authentication, illuminating at least a second light source that causes no glint from the eye;
- and
- B comprises:
- responsive to the demand for eye tracking, illuminating at least a first light source with no light diffuser positioned between the first light source and an eye;
- and
- responsive to the demand for authentication, illuminating at least a second light source with at least one light diffuser positioned between the second light source and the eye.
