The last finding in this explosion of new devices is a gesture control peripheral: the Myo. Developed by a Canadian company, it is a brace that is placed around the forearm. The brace contains sensors that detects movements:

  • translations and rotations of the arm, probably with MEMS,
  • plus apparently moves of muscles inside the arm that are interpreted to deduce moves of the hand.

This is an astounding idea! The company has surely sent a lot of money and engineer's time to develop this device. I see immediate applications in the field of surgery or other medical applications where sterility is important and can be preserved with such device.
If a surgeon has to touch the mouse or the touchscreen of a computer to view medical data, his hands "losses" sterility. With such device, no concern about sterility. It is preserved and the surgeon can open, view, scroll, zoom-in zoom-out with dedicated movements.
Some may say that the kinect already allows to do so. But the kinect has its drawbacks: the doctor has to be in front of the kinect to be detected and the kinect emits IR waves that can disturb other medical devices.

I don't put the link to the myo website here; you'll probably find it easily with your favorite search engine.

BTW, Remember that mice are the most intelligent life form on planet earth!
