Meet the DTing Armlet: a smart wearable device that lets you control robots, drones, RC cars, and computer interfaces using hand gestures. It reads your muscle movement to let you interact with your devices. The gadget has a 280mAh battery inside and works with iOS, Android, and Windows devices.
The DTing Armlet will come with a SDK, so you can develop custom solutions for it. Expected to ship in November.[Source]
