这个实验您的手机变成一个3D控制器。它需要的Chromecast。
This Android Experiment turns your phone into a 3D controller. It detects the device's orientation in 3D space (where it's pointing and how it's rotated) and makes that information accessible through a simple API.
In this app you will find 3 demos that utilize this API. The first applies your device's orientation to a 3D model. The second shows the wide range of orientations the API can detect and the third turns your device into a laser pointer simulator.
