Presently, we will write our own input component that maps the Unity (or SDK) input to our own simple API in MyInputController. Then, we'll write a BalloonController that polls the input, as illustrated:

The version for Daydream has the DaydreamPlayerprefab. It makes sense to add our MyInputController component to MeMyselfEye, as it may make device-specific SDK calls. In this way, should you want to maintain camera rig prefabs for a variety of platforms, and swap them in and out as you build the project for a different VR target, the API that is exposed to the rest of your application will be consistent and...
