Scientists create new electronic sunglasses: can track brain, eyeballs and more

According tomedia reports, a test sunglasses, it can monitor the health of users, let them control the game and according to their own needs to convert it into sunglasses. The prototype is believed to have been developed by a team led by Associate Professor Suk-Won Hwang from the KU-KIST Graduate School of Fusion Science and Technology at Koryo University in South Korea.

Scientists create new electronic sunglasses: can track brain, eyeballs and more

The “electronic glasses” use a 3D printing frame and place flexible electrodes around the wearer’s ears and eyes. The former sensor is equivalent to an electroencephalogram (EEG) and is used to monitor the brain’s electrical activity, while the latter functions like an electro-eye map (EOG) to track eye movement. Both types of data are processed by wireless transmission of glasses.

In laboratory tests, EEG successfully recorded the volunteers’ alpha rhythms, which in turn monitored their health. EOG’s data allowed participants to play a brick-and-mortar video game by simply moving their eyes. As you can imagine, such a feature might be used in hands-free control of computers or in assistive technologies designed for persons with disabilities.

In addition, the electronic glasses have an ultraviolet sensor on one of the legs that can be used to measure the intensity of the incoming UV rays. When the sunlight is bright enough, the sensor triggers the UV gel inside the lens to darken the lens, temporarily turning the glasses into sunglasses.

Finally, the researchers installed an accelerometer on the same lap as a light sensor. It tracks the user’s posture and gait and detects it when they fall. This means that the glasses can be used in virtual reality systems or used to monitor people in the elderly, automatically sending alarms if an accident is detected.
