Multifunctional e-Glasses Monitor Health, Protect Eyes, Control Video Game

American Chemical Society via Phys.org / May 27,2020

The researchers built the glasses’ frame with a 3-D printer and then added flexible electrodes near the ears (EEG sensor) and eyes (EOG sensor).

They also added a wireless circuit for motion/UV sensing on the side of the glasses and a UV-responsive, color-adjustable gel inside the lenses.

When the sensor detected UV rays of a certain intensity, the lenses changed color and became sunglasses.

The motion detector allowed the researchers to track the posture and gait of the wearer, as well as detect when they fell.

The EEG recorded alpha rhythms of the brain, which could be used to monitor health.

Finally, the EOG monitor allowed the wearer to easily move bricks around in a popular video game by adjusting the direction and angle of their eyes.

Wait . . . could I just ask you a few questions about the part I put in boldface, please?
