Cornell research explained: Wristband uses echos, AI to track hand positions

We're taking the latest research from Cornell and breaking it down, just for you!

Wristband uses echos, AI to track hand positions for VR and more

The main points: Scientists developed a wristband wearable that uses sound waves to detect hand movement. With EchoWrist, people could use one-handed gestures to play virtual reality games, control slides, or even use a smartphone to read a recipe in real-time as they cook. The device uses two tiny speakers to bounce inaudible sound off the hand and any hand-held objects. 

Why it’s important: The new device is smaller and consumes less energy than previous models, and could even be used on an off-the-shelf smartwatch.
