How to make a Multi-function magic bracelet?

hello, I have spend some time on study the [b]3-Axis Digital Accelerometer/b, and now I have made my first generation of magic bracelet, it is a gesture recognition device with Infrared Emitter & Receiver. Magic Bracelet makes it possible to control(turn on/off basically) your appliances(such as TV/ air-condition/ fan and other types of remote control devices) with gesture movement. For more information, you can view

Now I want to extend functionality of the magic bracelet, to make it a a better product. The direction that I can think of include “walker”,“Sleep quality monitoring”,“trajectory tracking”. I need more good idea and I would like more people to join with me! Will you be that guy?

I wear a normal bracelet but never a magic bracelet with the gesture recognition

Could you include heartbeat monitoring in that device?

then I think it will be good
