如何使用Microsoft Kinect for Windows SDK ver 1.7 C#检测打开/

首先,我们需要一个看起来像这样的虚拟类：

public class DummyInteractionClient : IInteractionClient
{
    public InteractionInfo GetInteractionInfoAtLocation(
        int skeletonTrackingId,InteractionHandType handType,double x,double y)
    {
        var result = new InteractionInfo();
        result.IsGripTarget = true;
        result.IsPressTarget = true;
        result.PressAttractionPointX = 0.5;
        result.PressAttractionPointY = 0.5;
        result.PressTargetControlId = 1;

        return result;
    }
}

然后,在主应用程序代码中,我们需要宣布关于交互事件处理程序,如下所示：

this.interactionStream = new InteractionStream(args.NewSensor,new DummyInteractionClient());
                this.interactionStream.InteractionFrameReady += InteractionStreamOnInteractionFrameReady;

最后,处理程序本身的代码：

private void InteractionStreamOnInteractionFrameReady(object sender,InteractionFrameReadyEventArgs e)
    {
        using (InteractionFrame frame = e.OpenInteractionFrame())
        {
            if (frame != null)
            {
                if (this.userInfos == null)
                {
                    this.userInfos = new UserInfo[InteractionFrame.UserInfoArrayLength];
                }

                frame.CopyInteractionDataTo(this.userInfos);
            }
            else
            {
                return;
            }
        }



        foreach (UserInfo userInfo in this.userInfos)
        {
            foreach (InteractionHandPointer handPointer in userInfo.HandPointers)
            {
                string action = null;

                switch (handPointer.HandEventType)
                {
                    case InteractionHandEventType.Grip:
                        action = "gripped";
                        break;

                    case InteractionHandEventType.GripRelease:
                        action = "released";

                        break;
                }

                if (action != null)
                {
                    string handSide = "unknown";

                    switch (handPointer.HandType)
                    {
                        case InteractionHandType.Left:
                            handSide = "left";
                            break;

                        case InteractionHandType.Right:
                            handSide = "right";
                            break;
                    }

                    if (handSide == "left")
                    {
                        if (action == "released")
                        {
                            // left hand released code here
                        }
                        else
                        {
                            // left hand gripped code here
                        }
                    }
                    else
                    {
                        if (action == "released")
                        {
                            // right hand released code here
                        }
                        else
                        {
                            // right hand gripped code here
                        }
                    }
                }
            }
        }
    }
