Smart e-glasses monitor human brain waves and body movements and control video games
Fitness tracker bracelets and watches provide useful information such as steps and heart rate, but usually cannot provide detailed data about the wearer’s health. Currently, researchers ACS Applied Materials and Interface Has developed smart electronic glasses (e-glasses) that not only monitor human brain waves and body movements, but also act as sunglasses and allow users to control video games with eye movements.
Devices that measure electrical signals from the brain (electroencephalogram; EEG) or eyes (electroencephalogram; EOG) not only help diagnose conditions such as epilepsy and sleep disorders, but also help control human-machine interface computers. I will. However, obtaining these measurements requires stable physical contact between the skin and the sensor. This is difficult on a stiff device. Suk-Won Hwang and his colleagues incorporated soft and electrically conductive electrodes into e-glass to wirelessly monitor brain waves and EOG signals, ultraviolet (UV) intensity, body movement and posture, while also functioning as a human-machine interface. I was hoping to do it.
Researchers created a frame of glasses with a 3D printer and added flexible electrodes near the ears (EEG sensor) and eyes (EOG sensor). In addition, a wireless circuit for motion / UV sensing was added to the side of the glasses, and a UV-responsive color-adjustable gel was added inside the lens. When the sensor detected a certain intensity of UV light, the color of the lens changed and it became sunglasses. The motion detector allowed researchers to track the wearer’s posture and gait, and detect falling. EEG records the alpha rhythm of the brain and can be used to monitor health. Lastly, the EOG monitor makes it easy to move bricks by adjusting the eyes and orientation and angle in popular video games. Researchers say electronic glasses could be useful in digital healthcare and virtual reality applications.
