Question

滑动手势Left，Right，Up和Down未优化。如果必须使用向上滑动执行任务，它将与左滑动混淆并仍然执行它。请建议我优化的参数以区分滑动。或完美滑动识别的命令它也与圆圈和滑动相混淆。我添加了我的代码。在一个帧中，只能检测到一个手势。我如何限制它。

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)

开箱即用的手势在3.x（猎户座）中被弃用，因为它们不可靠。最好的办法是了解SDK并只创建自己的手势，你可以超越已经开箱即用，更可靠。一切都与3d定位有关，所以要注意你的Y，X，Z，使用debuger指针或创建自己的调试系统来看它的行为。

Leap Motion在不同的手势类型之间混淆。如何优化？
