Canadian firm Thalmic Labs has announced the end of sales of the Myo armband, a gesture-control device which was being explored in the realm of prosthetics. Last week, Thalmic Labs co-founder Stephen Lake said in a Medium post that sales of the Myo Gesture Control Armband were officially ending, despite the device's popularity with researchers and developers. The Myo armband used electromyography (EMG) sensors to measure and record electrical impulses given off by our muscles. By digesting these pulses, the armband would control a device based on the gesture, which, in turn, made the armband an "extension" of our actions. The use of EMG in consumer devices was a new concept, and as ZDNet found in a review of the $199 device, there were teething issues.
