陀螺仪和加速度计数据来自Windows

Question

微软Surface Pro有陀螺仪和加速度计、Windows 8和完整的。net框架。

我发现大多数关于运动API的文章都指向了Windows Phone 8 API。

我应该使用什么。net框架名称空间和类来获取陀螺仪和加速度计数据?

Answer 1

我只是根据文档工作- http://msdn.microsoft.com/en-us/library/ie/windows.devices.sensors

using Windows.Devices.Sensors;
private Accelerometer _accelerometer;
private void DoStuffWithAccel()
{
   _accelerometer = Accelerometer.GetDefault();
   if (_accelerometer != null)
   {
      AccelerometerReading reading = _accelerometer.GetCurrentReading();
      if (reading != null)
      double xreading = reading.AccelerationX;
      ... etc.
   }
}

还没有测试过，但它应该适用于任何Windows Store应用程序-如果你想让它作为控制台/Windows窗体应用程序运行，你需要更改targetplatform:

1. 右键单击项目->卸载项目
2. 按照下面的内容https://software.intel.com/en-us/articles/using-winrt-apis-from-desktop-applications

对于surface pro，您需要使用Windows 8.1库，而不是Windows Phone 8.1库。

应该在同一个Windows.Devices.Sensors命名空间

using Windows.Devices.Sensors;
...
//if you aren't already doing so, and you want the default sensor
private void Init()
{
    _accelerometer = Accelerometer.GetDefault();   
    _gyrometer = Gyrometer.GetDefault();
}
...
private void DisplayAccelReading(object sender, object args)
{
    AccelerometerReading reading = _accelerometer.GetCurrentReading();
    if (reading == null)
        return;
    ScenarioOutput_X.Text = String.Format("{0,5:0.00}", reading.AccelerationX);
    ScenarioOutput_Y.Text = String.Format("{0,5:0.00}", reading.AccelerationY);
    ScenarioOutput_Z.Text = String.Format("{0,5:0.00}", reading.AccelerationZ);
}
...
private void DisplayGyroReading(object sender, object args)
{
    GyrometerReading reading = _gyrometer.GetCurrentReading();
    if (reading == null)
        return;
    ScenarioOutput_AngVelX.Text = 
                  String.Format("{0,5:0.00}", reading.AngularVelocityX);
    ScenarioOutput_AngVelY.Text = 
                  String.Format("{0,5:0.00}", reading.AngularVelocityY);
    ScenarioOutput_AngVelZ.Text = 
                  String.Format("{0,5:0.00}", reading.AngularVelocityZ);
}
