One of the problems of mastering gadgets by older people is the total incompatibility of small print and pictures on small screens with senile vision changes. In old age, the organs of vision lose the ability to accurately focus on an object, the muscles around the lens lose elasticity, and the eyes "do not move." Corrective lenses do not solve the problem, but Stanford recently created the Autofocal headset, which will become a kind of prosthetic for the eyes.
The principle of operation of an autofocal eye headset is simple: the system tracks the focus of the eyes and automatically adjusts a set of lenses and filters that simulate the natural vision of the object to which our attention is directed. The eyes practically do not need to move, the sensors catch the change of the object of interest, and then the whole picture in front of the eyes changes entirely.
This is how they look
Autofocal works like an analogue of a motorized arm or leg prosthesis. The device receives a signal from the nervous system for action, and itself, based on the analysis of the current situation, performs a series of micro-maneuvers to achieve the goal. For this, the headset is equipped with an impressive list of devices: depth cameras, motion sensors, pupil trackers, microcontrollers, motion sensors, etc. True, it looks like a gadget from the cyber-punk universe - massive and inconvenient.
A prototype is a prototype - it will be shown in detail only at a conference in August this year. The developers say that in all experiments they got noticeably better results than when using passive corrective lenses. Making an eye prosthesis compact, lightweight and cheap is just a matter of technique and time.
