Gyroscopes: tracking limb movement. How to do?

Question

Android

Good day everyone.
I would like to track the movement of the arm from the shoulder to the hand, that is, 3 joints. Kinect does not help in all conditions. I thought to quickly collect an analogue of www.priovr.com (since who knows when they will be sold).
The easiest option is to buy 3 of the simplest Android phones, where there is a gyroscope and a compass and accelerometers, which in total (I hope I’ll check it in practice, I can unsubscribe) give a little drift. Tie each one to the desired part of the limb, and send the determined angles via wi-fi to the computer port, which already synchronizes by time stamps, and generalizes everything into a model.
I myself am a proger, with all that it implies. Can someone advise how to solve the problem less treacherously? Maybe it's easier / better quality to buy a separate IMU and connect them to some Raspberry pi or something like that? (But also not to go deep into the iron).
Yes, if someone wants to join in tinkering with such a thing, or can advise a person who has already fiddled with such a thing or may be interested, I will be glad to the company!
Thanks in advance for all the advice.

Answer 1

So far I have identified two options. Both can/have self-powered, and serial bluetooth interface + ready-made either:
1. x-BIMU - cool but expensive ( www.x-io.co.uk/products/x-bimu/)
2. Playstation move - cheap , and I think that's enough for now, I'll most likely experiment with it ( us.playstation.com/ps3/playstation-move/).
Has anyone had experience?
