Hi guys,
I got a new project to make a pretty unconventional fitness game controller for android.
The ideea is the following: using the Android VR technology (Cardboard or Dive) it was pretty simple to create a basic game (3d world to walk around) using Unity3D and Dive SDK.
I want to use this and make a fitness app which will be controlled by running on a treadmill (or using a workout bike). Something like the old Nintendo Wii and the running game from Sports. Or a game like Temple Run, in which running the treadmill faster, gets you faster in the game.
For this I would like to create a game controller which records the leg movements, direction, body position, etc. which would then influence the actions in the game. A lot of detals I still need to work out.
So the question is, does anybody know of a guide or tutorial on how to create a game controller like this, using an Arduino (or only the Atmega, it has to be small to carry while running) a bluetooth module (which would you suggest?), and all the body sensors.
I would like to be able to record more then a conventional controller does (more than just up, down, left, right, etc) that's why I would like to build one and not buy one and break it apart and hack into it. That, and for kicks 
Best regards,
Felix
