Myo motion control and gesture control armband bracelet uses arm muscle activity and EMG signals to control digital devices over Bluetooth 4.0 Low Energy. Basically, you program the braclet to perform certain functions when you move your arm. Based on your arm muscle activity it complets those functions on your computer. It can do things like move slide, stop and start videos and music, open programs, and many more. It is also being developed to work with video game systems, remote control vehicles, and many more technology pieces.
This could be a great tool in education. You can present and control your computer remotley without even looking down. You can perfom more than one function with it, without even going near your computer. This would also be a great tool to show off and use when doing professional development talks. Maybe I will get luck and Myo will send me one to show off during my ed tech presentations.
