Abstract
Aspects of the present invention relate to methods and systems for measuring and managing the brightness of digital content in a field of view of a head-worn computer.
Claims14
A system comprising:
- an optics module comprising:
- a splitter comprising a polarizer and a mirror;
- and
- an illumination light source configured to emit illumination light towards a first surface of the splitter;
- a reflective display configured to receive illumination light from the illumination light source via a quarter-wave plate and further via the polarizer, and further configured to reflect image light toward a user's eye via the quarter-wave plate;
- an infrared light source configured to emit infrared light towards a second surface of the splitter, the second surface different from the first surface, wherein the mirror of the splitter is configured to reflect the infrared light toward the user's eye;
- and
- a first sensor configured to receive the infrared light reflected in the user's eye.

A method comprising:
- receiving, at a reflective display of a wearable head device, illumination light from an illumination light source of an optics module via a quarter-wave plate and further via a polarizer, the illumination light emitted towards a first surface of a splitter;
- in response to the reflective display receiving the illumination light, reflecting image light toward a user's eye via the quarter-wave plate;
- emitting, via an infrared light source, infrared light towards a second surface of the splitter, the second surface different from the first surface, wherein a mirror of the splitter is configured to reflect the infrared light toward the user's eye;
- and
- receiving, at a first sensor, the infrared light reflected in the user's eye,
- wherein the optics module comprises the splitter, the splitter comprising the polarizer and further comprising the mirror.
