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，可以用手势移动鼠标光标，也可以点击。问题是每当我想将光标移动到角落时我需要在kinect前面迈出一步来做到这一点。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;
    }

我已经尝试了这个kinect for c# dev和similar to youtube video code但是因为在本教程中他使用sdk 1.0并且一些方法是绝对的所以我无法跟踪我的手有人可以帮助我如何用光标正确地缩放我的手部动作，这样我可以用手轻微移动光标移动到所有的屏幕上吗？

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

假设您已添加使用Microsoft.Kinect引用

首先，您首先将此部分添加到MainWindow.xaml
中

<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>

然后在Mainwindow.Xaml.cs中添加这行代码，你就可以了！

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！
