This teen invented a watch that warns you about touching your face so you don't catch coronavirus - CNN

"However it wasn't until I saw the severity of the virus first-hand, when both my parents contracted Covid-19, that I truly appreciated just what we were dealing with."

The watch works by recognizing gestures that are associated with hand movements towards the face.

Combining unique technology and algorithms to differentiate between predicted face touchings and other hand movements, the watch vibrates every time a wearer's hand gets close to the face.
