Researchers develop electronic glasses to monitor health and control video games


Researchers have developed smart “e-glasses” glasses that not only monitor a person’s brain waves and body movements but also act as sunglasses and allow users to control video games with eye movements, as devices that measure electrical signals from the brain or eye can help diagnose conditions such as epilepsy Sleep disturbances, in addition to controlling computers in human and machine interfaces.

According to the Indian TOI website, to obtain these measurements requires constant physical contact between the skin and the sensors, which is difficult with solid devices, and the research team from the University of Korea wanted to integrate soft and conductive electrodes in electronic glasses that can wirelessly monitor brain and eye signals, intensity of rays Ultraviolet, body movements or positions, while also acting as a human-machine interface.


According to the results published in the journal ACS Applied Materials & Interfaces, the researchers built the eyeglasses frame using a 3D printer, then added flexible electrodes near the ears (EEG sensor) and eyes (EOG sensor).

They also added a wireless motion / UV sensor circuit on the side of the glasses and an adjustable UV-responsive color gel inside the lenses, and when the sensor detected UV at a certain intensity, the color of the lenses changed and became sunglasses.

The motion detector allowed researchers to track the position and walking of its wearer, as well as detect the time of its fall., EEG recorded alpha rhythms in the brain, which could be used to monitor health, and finally, the EOG screen allowed its wearers to move bricks easily in a popular video game by adjusting the direction and angle of their eyes And, the researchers said, electronic glasses can be useful for digital healthcare or virtual reality applications.
