DEVICE, SYSTEM AND METHOD OF TRACKING THE VISUAL DIRECTION AT THE BASIS OF PHOTODETECTION BY A EYE-MOUNTED DEVICE Russian patent published in 2018 - IPC G02C7/04 

FIELD: medicine.

SUBSTANCE: group of inventions refers to contact lenses. Eye-mounted device, the system and method for implementing the device includes a first circuit and a second circuit, each comprising a corresponding photodiode. Second circuit is configured to provide a light sensitivity profile that is more linear than the light sensitivity profile provided by the first circuit. Perception of the light beam by the first circuit leads to the development of the first signal, which shows the level of ambient light in the environment. Another measurement of the light beam by the second circuit results in the generation of a second signal. Next, the visual direction is detected using the cornea of the user's eye and performed on the basis of at least part of the first signal and the second signal.

EFFECT: technical result is an accurate tracking of the user's visual direction.
