Background: 背景：

I am currently developing a Web-Based 3D multi-player motion sensor console game (Air Table Tennis). 我目前正在开发基于Web的3D多人运动传感器控制台游戏（Air Table Tennis）。 Mobile is acting as a racket for game, Sensor data (gyroscope,accelerator,rotation-vectors) is used rotate racket. 移动设备充当游戏的球拍，传感器数据（陀螺仪，加速器，旋转矢量）用于旋转球拍。 Mobile transmit sensor data to game engine(BabylonJS,NodeJS,SocketIO) where on real time I map those values. 移动设备将传感器数据传输到游戏引擎（BabylonJS，NodeJS，SocketIO），在其中我实时映射这些值。

Problem: 问题：

I want when user(holding mobile) moves in any direction my racket on game screen will also move in that particular direction. 我想要当用户（手持移动设备）朝任何方向移动时，我在游戏屏幕上的球拍也朝该特定方向移动。

For this i have studied azimuth values,velocity-graphs and Google Project Tango(Tango is using Computer Vision which in my case can not be implemented) but I am not getting anywhere. 为此，我研究了方位角值，速度图和Google Project Tango（Tango正在使用Computer Vision，在我的情况下无法实现），但我什么都没得到。 If someone suggests me anything it'll be highly appreciated! 如果有人建议我什么，将不胜感激！

You may want to look at this section here: https://developer.android.com/guide/topics/sensors/sensors_overview.html#sensors-coords 您可能需要在此处查看此部分： https : //developer.android.com/guide/topics/sensors/sensors_overview.html#sensors-coords

Just keep in mind that not all devices have gyroscopes or magnetometers, so getting phone positions relative to the earth would be impossible on such devices. 请记住，并非所有设备都具有陀螺仪或磁力计，因此在此类设备上获取手机相对于地球的位置将是不可能的。
