Watch | A wearable that can track facial expressions while wearing masks

A video about C-Face, a wearable sensing technology that can track facial expressions.

Researchers at Cornell University have developed an ear-mounted wearable sensing technology that can track facial expressions, even when someone is wearing a face mask.

The technology, C-Face, uses two tiny cameras and deep learning algorithm to continuously observe facial contours and reconstruct expressions. The researchers have used this technology in prototype devices like earphones and headphones.
