Head Movment - Tool Andoid and Iphone

What we will do: - Use a VR where you can put your Phone into as Screen. - Start the App -> Phone must be placed on a straght surface for calibration - Put it on the probands head - Screen will show a 3d Image of a nice natur landscape. - when we press bluetooth remote the device takes this as base position and starts recording - Head is moved (left, right, up, down) and all movement are recorded. - Press Bluetooth remote again and recording stops. - App shows the data and stores it in log. Data should show DEGREE of movement in every direction based on the start position. First implement only for Andoroid. Once all is working convert to IOS as well.
