Original Abstract Submitted
apparatuses, methods, and systems for an ocular hydration sensor/reflectometer system in a near-eye display device are described. in one aspect, a near-eye display device may include a projector to project light onto a user's eye, a photodetector to receive reflections from the tear film of the user's eye (e.g., the tear glints), and a controller to make ocular hydration measurements from the received reflections. the ocular hydration measurements may be used to (1) re-calibrate an eye tracking system of the near-eye display device (by changing parameters such as, e.g., light intensity and/or exposure time); (2) prompt the user to take remedial action; and/or (3) keep track of the user's eye health over time. the projector, photodetector, and/or controller may be integrated into, separate from, or partially integrated/partially separate from the eye tracking system. collective die-on-wafer processing, embedded motheye lens structures, and adaptive thermal management using thermoelectric coolers are also described.
