Gesture recognition using an accelerometer

Looking to create a small device that will perform different functions based on the movements you make with it. There are a few devices on the market that seem to use this function (notably among them a TV remote control). Just wondering if anyone on here has done any such work. I only need to recognize about 10 functions.

I suppose I could also use a few mercury switches too... but these days, if I dropped it they'd probably have to evacuate the state :-)

Thanks for any leads/info,

Dave

    I don't think mercury switches will offer you the kind of data you require. But you can use a 3 axis accelerometer with a wireless link, such as an XBee to get started.

    You need to accumulate data and to create a context (such as a game or an application). Motions alone are not enough to do anything useful.

    Motions need to be interpreted simultaneous in the x, y, and z axis for rate and/or g-force. So some sophisticated maths are employed.
