You can be a Jedi too!

A company called Thalmic Labs have come up with a new armband sensor that allows users to control their computing devices using arm gestures. A boring example would be, you can use hand gestures to control your powerpoint presentation. But imagine all the cool things you can do with it. Control your smartphone like make a call, your mp3 player, interact with your robot, etc. It may even be possible to use this alongside speech and then all you have to do is just swish your arm and chant your mantra. You wear it on your forearm and therefore it picks up hand gestures without actually sitting your palm or fingers. This reminds me of the Sixth Sense project at MIT where hand gestures are captured via a tiny camera.

The company also provides developers with APIs to be able to explore new ways to user this sensor.
