Device Detects Which Hand Gesture a Person Intends to Make

A new device can recognize hand gestures based on electrical signals detected in the forearm. The system, which couples wearable biosensors with artificial intelligence (AI), could one day be used to control prosthetics or to interact with almost any type of electronic device. Reading hand gestures is one way of improving human-computer interaction. And while there are other ways of doing that, this solution also maintains an individual’s privacy.
