Leap Motion會在不同的手勢類型之間產生混淆。如何優化？

Question

滑動手勢向左，向右，向上和向下未優化。如果任務必須以向上滑動的方式執行，它會與左側滑動混淆並仍然執行它。請向我建議要優化的參數以區分滑動。或完美滑動識別的命令 此外，它會與圈和一個輕掃。 我已添加我的代碼。在一個單一的框架中，只有一個手勢應該被檢測到。我怎麼在這裏限制這個。

public MainWindow() 
{ 
InitializeComponent(); 

     this.controller = new Controller(); 

     this.listener = new LeapListener(this); 
     controller.AddListener(listener); 

     for (int iCount = 1; iCount < 23; iCount++) 
     { 
      images[iCount] = new BitmapImage(); 
      images[iCount].BeginInit(); 
      images[iCount].UriSource = new Uri("Images/" + iCount + ".png", UriKind.Relative); 
      images[iCount].EndInit(); 
     } 
     image.Source = images[1]; 
    } 



    delegate void LeapEventDelegate(string EventName); 




    public void LeapEventNotification(string EventName)

開箱即用的手勢在3.x（Orion）中不推薦使用，因爲它們不可靠。 要做的最好的事情就是了解SDK，並創建自己的手勢，你可以超越已經開箱即用的，更可靠的。 關於3D定位的一切，所以要注意你的Y，X，Z，使用debuger的手或創建你自己的調試系統，看看它的行爲。
