Watch the Myo wearable gesture control from Thalmic Labs in action in the video below. It is amazing and is supposed to ship late 2013 for $150.
The MYO senses gestures and movements in two ways: muscle activity, and motion sensing. When sensing the muscle movements of the user, the device can detect changes in hand gesture right down to each individual finger. When tracking the positioning in space of the arm and hand, the device can detect subtle movements in all directions. MYO uses Bluetooth 4.0 to communicate with other devices.
The MYO armband is supposed to ship late 2013 and you can pre-order it now for $149 here.
Watch the cool MYO video below to see the gesture controller in action.
The MYO reminded me about the Leap Motion 3D controller that was unveiled in May of last year. It was supposed to ship in February. It now says early 2013. It looks though promising that the Leap will ship soon as Leap Motion will exhibit at the SXSW 2013 show on March 9.
