At this point we all know how augmented reality works, which includes additional information to everyday reality, through the use of specific devices.
The new technology, developed by a team of engineers from Dartmouth College, does not need batteries and allows precise tracking of eye movement.
The latter is essential for augmented reality systems, so that the device knows where we are looking and can reflect the appropriate information in smart glasses.
Until now, eye tracking was expensive and complicated, in addition to requiring a lot of energy, but the new system uses near-infrared lights and photodiodes, which need very little energy.
To do this, the glasses will have small solar cells placed vertically on the side of the arms of the glasses, which will collect the necessary energy.
