如何使用kinect将光标移动到屏幕角落？

Question

我正在使用 kinect 360 和 windows sdk 1.8。我有一个用 c# wpf 开发的应用程序，它可以用手势移动鼠标光标，也可以单击。问题是每当我想将光标移动到角落时，我需要在 kinect 前面迈出一步才能做到这一点。但我想以这种方式缩放光标，所以我只需要移动我的手，光标就会移动到所有屏幕。

这是我正在尝试的代码

 void sensor_SkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs e)
    {
        bool receivedData = false;

        using (SkeletonFrame SFrame = e.OpenSkeletonFrame())
        {
            if (SFrame == null)
            {
                return;
            }
            else
            {
                skeletons = new Skeleton[SFrame.SkeletonArrayLength];
                SFrame.CopySkeletonDataTo(skeletons);
                receivedData = true;
            }
        }

        if (receivedData)
        {

            Skeleton currentSkeleton = (from s in skeletons
                                        where s.TrackingState == SkeletonTrackingState.Tracked
                                        select s).FirstOrDefault();

            if (currentSkeleton != null)
            {
                processing(currentSkeleton.Joints[JointType.HandRight]);
                click(currentSkeleton.Joints[JointType.HandLeft], currentSkeleton.Joints[JointType.Head]);
            }
        }
    }
    private void processing(Joint handright)
    {
        Microsoft.Kinect.SkeletonPoint vector = new Microsoft.Kinect.SkeletonPoint();
        vector.X = ScaleVector(1600, handright.Position.X);
        vector.Y = ScaleVector(900, -handright.Position.Y);
        vector.Z = handright.Position.Z;
        handright.Position = vector;

        zAxis = handright.Position.Z;



        leftofscreen = Convert.ToInt32(handright.Position.X);
        topofscreen = Convert.ToInt32(handright.Position.Y);

        SetCursorPos(leftofscreen, topofscreen);

    }
    private void click(Joint handleft, Joint head)
    {
        if (handleft.Position.Y > head.Position.Y)
        {
            mouse_event(LEFTDOWN, leftofscreen, topofscreen, 0, 0);
            mouse_event(LEFTUP, leftofscreen, topofscreen, 0, 0);

        }
    }

    private float ScaleVector(int length, float position)
    {
        float value = (((((float)length) / 1f) / 2f) * position) + (length / 2);
        if (value > length)
        {
            return (float)length;
        }
        if (value < 0f)
        {
            return 0f;
        }
        return value;
    }

我试过这个 kinect for c# dev and similar to youtube video code 但是因为在本教程中他使用的是 sdk 1.0 并且一些方法是绝对的所以我无法追踪我的手有人可以帮助我如何使用光标正确缩放我的手部移动，以便我可以通过手的轻微移动将光标移动到所有屏幕吗？

这里是Kinect sdk v2中的项目解决方案 https://github.com/bingcheng45/Kinect-v2-Hovering-Example

假设您已经添加了 using Microsoft.Kinect 引用

Basically first you add this section into the MainWindow.xaml

<k:KinectRegion x:Name="kinectRegion">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto" />
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>

            <Grid Grid.Row="0" Margin="10 0 10 20">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" />
                    <ColumnDefinition Width="*" />
                </Grid.ColumnDefinitions>


                <k:KinectUserViewer Grid.Column="1" Height="100" HorizontalAlignment="Center" VerticalAlignment="Top" />
                <TextBlock Grid.Column="1" HorizontalAlignment="Right" Margin="0 0 -1 0" VerticalAlignment="Bottom"  FontSize="18">Controls Basics</TextBlock>
            </Grid>

            <ContentControl Grid.Row="1" x:Name="navigationRegion">
                <Grid x:Name="kinectRegionGrid" Margin="10,20,10,20">
                    <Button x:Name="btnCenter" Content="CLICK HERE" HorizontalAlignment="Left" Margin="174,48,0,0" Style="{StaticResource 
                        FrameSelectorButtonStyle}" VerticalAlignment="Top" Width="158" Height="76"  MouseLeave="btnCenter_MouseLeave" Click="btnCenter_Click" MouseEnter="btnCenter_MouseEnter" Background="#FFC9C9C9" TouchEnter="btnCenter_TouchEnter"/>
                    <Label x:Name="lbtext" Content="Label" HorizontalAlignment="Left" Margin="51,31,0,0" VerticalAlignment="Top"/>

                </Grid>
            </ContentControl>
        </Grid>
    </k:KinectRegion>

然后只需在您的 Mainwindow.Xaml.cs 中添加这行代码即可！

public MainWindow()
        {
            InitializeComponent();

            //hovering start
            KinectRegion.SetKinectRegion(this, kinectRegion);

            App app = ((App)Application.Current);
            app.KinectRegion = kinectRegion;

            // Use the default sensor
            this.kinectRegion.KinectSensor = KinectSensor.GetDefault();
            //hovering end
        }

干杯！
