Kinect SDK1.7更改KinectCursor图像和大小
我下载了Kinect SDK 1.7、工具包，并使用了以下示例。
- ControlBasics WPF
- InteractionGallery WPF.
我发现Kinect Toolkit内部使用交互框架来检测手的位置/手势，并相应地将其映射到Kinect控件。
我有一个要求，在这里，我想捕捉一个抓事件上的Kinect Tile Button。因为默认的KinectTileButton不提供抓地力事件。我在按钮上添加了一个抓地力事件处理程序。
KinectRegion.AddHandPointerGripHandler(kinectButton, OnHandPointerCaptured);
private void OnHandPointerCaptured(object sender, HandPointerEventArgs handPointerEventArgs)
{
// Add code here
}我在OnHandPointerCaptured方法中放置了一个调试断点，并且当我抓住KinectTileButton时能够收到适当的点击。但出于某种原因，我没有看到KinectCursor图像在KinectScrollViewer控件上发生变化。我尝试在isGripTarget类中设置KinectButtonBase属性，但没有帮助。
private void InitializeKinectButtonBase()
{
KinectRegion.AddHandPointerPressHandler(this, this.OnHandPointerPress);
KinectRegion.AddHandPointerGotCaptureHandler(this, this.OnHandPointerCaptured);
KinectRegion.AddHandPointerPressReleaseHandler(this, this.OnHandPointerPressRelease);
KinectRegion.AddHandPointerLostCaptureHandler(this, this.OnHandPointerLostCapture);
KinectRegion.AddHandPointerEnterHandler(this, this.OnHandPointerEnter);
KinectRegion.AddHandPointerLeaveHandler(this, this.OnHandPointerLeave);
// Use the same OnHandPointerPress handler for the grip event
KinectRegion.AddHandPointerGripHandler(this, this.OnHandPointerPress);
//Set Kinect button as Grip target
// KinectRegion.SetIsPressTarget(this, true);
KinectRegion.SetIsGripTarget(this, true);
}如何将KinectCursor图像从openhand图标更改为抓地力，以及大小。

我发现-
1)光标图像和大小-这两个示例都使用定义自定义控件(KinectTileButton、KinectScrollViwer、KinectRegion等)的Microsoft.Kinect.Toolkit.Controls项目。用在这些样本中。Kinect光标图像和大小被定义为Microsoft.Kinect.Toolkit.Controls ->Themes->Generic.xaml中的资源。在文件中搜索以下内容-
<Style TargetType="{x:Type local:KinectCursor}">您可以根据需要对此进行修改。无法找到任何属性/钩子直接从UI中控制这一点。
2) Tile Button上的抓地力事件- Kinect Button支持各种事件，这些事件可以根据您的愿望进行细分和操作。参见此Hand over button event in Kinect SDK 1.7
3)更改光标映像以抓取Tile Button - Microsoft.Kinect.Toolkit.Controls项目使用KinectCursorVisualizer.cs和KinectCursor.cs在UI上呈现虚拟手动游标。Open /Grip视觉状态是通过KinectCursor.cs中定义的这个依赖属性来控制的。
public static readonly DependencyProperty IsOpenProperty = DependencyProperty.Register(
"IsOpen",
typeof(bool),
typeof(KinectCursor),
new UIPropertyMetadata(true, (o, args) => ((KinectCursor)o).EnsureVisualState()));快速查找属性IsOpen上的所有引用会告诉我们，设置该属性的唯一位置是KinectCursorVisualizer.cs-> OnHandPointersUpdated方法。线路- 229
// Set open state
cursor.IsOpen = !pointer.IsInGripInteraction;这个pointer.IsInGripInteraction属性设置在KinectAdapter.cs第678行
handPointer.IsInGripInteraction = newIsInGripInteraction;如果您查看这一行上面的代码，您会发现，只有当目标元素定义了QueryInteractionStatusHandler并将args.Handled、args.IsInGripInteraction属性设置为true时，该属性才会设置为true。
因为KinectScrollViewer已经定义了这个处理程序，所以您可以看到一个抓地力图像。
private void InitializeKinectScrollViewer()
{
KinectRegion.AddHandPointerGotCaptureHandler(this, this.OnHandPointerCaptured);
KinectRegion.AddHandPointerLostCaptureHandler(this, this.OnHandPointerLostCapture);
KinectRegion.AddHandPointerEnterHandler(this, this.OnHandPointerEnter);
KinectRegion.AddHandPointerMoveHandler(this, this.OnHandPointerMove);
KinectRegion.AddHandPointerPressHandler(this, this.OnHandPointerPress);
KinectRegion.AddHandPointerGripHandler(this, this.OnHandPointerGrip);
KinectRegion.AddHandPointerGripReleaseHandler(this, this.OnHandPointerGripRelease);
//This is the QueryInteractionStatusHandler
KinectRegion.AddQueryInteractionStatusHandler(this, this.OnQueryInteractionStatus);
KinectRegion.SetIsGripTarget(this, true);
this.scrollMoveTimer.Tick += this.OnScrollMoveTimerTick;
this.scrollViewerInertiaScroller.SlowEnoughForSelectionChanged += this.OnSlowEnoughForSelectionChanged;
// Create KinectRegion binding
this.kinectRegionBinder = new KinectRegionBinder(this);
this.kinectRegionBinder.OnKinectRegionChanged += this.OnKinectRegionChanged;
}但是KinectTileButton (扩展KinectButtonBase)没有定义这个处理程序。
private void InitializeKinectButtonBase()
{
KinectRegion.AddHandPointerPressHandler(this, this.OnHandPointerPress);
KinectRegion.AddHandPointerGotCaptureHandler(this, this.OnHandPointerCaptured);
KinectRegion.AddHandPointerPressReleaseHandler(this, this.OnHandPointerPressRelease);
KinectRegion.AddHandPointerLostCaptureHandler(this, this.OnHandPointerLostCapture);
KinectRegion.AddHandPointerEnterHandler(this, this.OnHandPointerEnter);
KinectRegion.AddHandPointerLeaveHandler(this, this.OnHandPointerLeave);
KinectRegion.SetIsPressTarget(this, true);
}如何定义此处理程序？-向UI添加以下简单内容。可以添加到构造函数中。
//Add the handler
KinectRegion.AddQueryInteractionStatusHandler(kinectButton, OnQuery);定义Handler
//Variable to track GripInterationStatus
bool isGripinInteraction = false;
private void OnQuery(object sender, QueryInteractionStatusEventArgs handPointerEventArgs)
{
//If a grip detected change the cursor image to grip
if (handPointerEventArgs.HandPointer.HandEventType == HandEventType.Grip)
{
isGripinInteraction = true;
handPointerEventArgs.IsInGripInteraction = true;
}
//If Grip Release detected change the cursor image to open
else if (handPointerEventArgs.HandPointer.HandEventType == HandEventType.GripRelease)
{
isGripinInteraction = false;
handPointerEventArgs.IsInGripInteraction = false;
}
//If no change in state do not change the cursor
else if (handPointerEventArgs.HandPointer.HandEventType == HandEventType.None)
{
handPointerEventArgs.IsInGripInteraction = isGripinInteraction;
}
handPointerEventArgs.Handled = true;
}您可能必须根据您的要求对此进行调整。快乐连接:)
