Gesture-control armband

The Myo armband literally listens to your muscles talking.
An expandable armband made up of eight muscle-sensing
modules, its suite of medical-grade EMG (electromyography)
sensors reads and responds to the electrical activity
generated in the muscles of your forearm as you produce
different gestures – including squeezing and rotating your
fi st, waving your hand, spreading your fi ngers and pointing.
While it’s hard to call Myo a hands-free device, it is touchfree,
letting you do stuff that would otherwise involve
connecting physically with controls or a computer. Its
creators are connecting with developers to come up with
applications from gaming and audio-video playback
control, right through to sign-language interpretation and
controlling lighting at concerts.
