我正在尝试使用Kinect SDK进行类似Kinect的冒险活动,即当鼠标停留在特定区域一段特定时间时,本机点击事件将被触发。 问题是我没有得到预期的结果,因为我随机点击大部分时间。我试图检查断点等。 大多数情况下,当我的手不可见时,光标会移到屏幕的一角并开始点击。这很可能是因为Math.Abs(lastX - cursorX) < threshold
设置为true。鼠标在某个区域内点击一段时间
我已经尝试将阈值更改为200,但它会触发点击开始,然后我不会得到预期的左键单击,当我将光标放在某个位置一段时间。任何建议将不胜感激。下面的代码:
//SkeletonFrameReadyevent
foreach (SkeletonData sd in e.SkeletonFrame.Skeletons)
{
if (sd.TrackingState == SkeletonTrackingState.Tracked)
{
// make sure both hands are tracked
if (sd.Joints[JointID.HandLeft].TrackingState == JointTrackingState.Tracked &&
sd.Joints[JointID.HandRight].TrackingState == JointTrackingState.Tracked)
{
int cursorX, cursorY;
// get the left and right hand Joints
Joint jointRight = sd.Joints[JointID.HandRight];
Joint jointLeft = sd.Joints[JointID.HandLeft];
// scale those Joints to the primary screen width and height
Joint scaledRight = jointRight.ScaleTo((int)SystemParameters.PrimaryScreenWidth, (int)SystemParameters.PrimaryScreenHeight, SkeletonMaxX, SkeletonMaxY);
Joint scaledLeft = jointLeft.ScaleTo((int)SystemParameters.PrimaryScreenWidth, (int)SystemParameters.PrimaryScreenHeight, SkeletonMaxX, SkeletonMaxY);
// figure out the cursor position based on left/right handedness
cursorX = (int)scaledRight.Position.X;
cursorY = (int)scaledRight.Position.Y;
//default false, for mouse move, set to true for mouse click
bool leftClick;
if (lastY == 0)
{
lastX = cursorX;
lastY = cursorY;
}
leftClick = false;
if (Math.Abs(lastX - cursorX) < threshold && Math.Abs(lastY - cursorY) < threshold)
{
if (Math.Abs(lastClick.Subtract(DateTime.Now).TotalSeconds) > 1)
{
//Mouse click here
leftClick = true;
}
}
//Mouse click when leftDown is true, else Mousemove
NativeMethods.SendMouseInput(cursorX, cursorY, (int)SystemParameters.PrimaryScreenWidth, (int)SystemParameters.PrimaryScreenHeight, leftClick);
return;
}
}
}
NativeMthods.cs类有这样的功能:
public static void SendMouseInput(int positionX, int positionY, int maxX, int maxY, bool leftDown)
{
if(positionX > int.MaxValue)
throw new ArgumentOutOfRangeException("positionX");
if(positionY > int.MaxValue)
throw new ArgumentOutOfRangeException("positionY");
Input[] i = new Input[2];
// move the mouse to the position specified
i[0] = new Input();
i[0].Type = InputMouse;
i[0].MouseInput.X = (positionX * 65535)/maxX;
i[0].MouseInput.Y = (positionY * 65535)/maxY;
i[0].MouseInput.Flags = MouseEventAbsolute | MouseEventMove;
// determine if we need to send a mouse down or mouse up event
if(leftDown)
{
i[1] = new Input();
i[1].Type = InputMouse;
i[1].MouseInput.Flags = MouseEventLeftDown;
i[1].MouseInput.Flags |= MouseEventLeftUp;
}
// send it off
uint result = SendInput(2, i, Marshal.SizeOf(i[0]));
if(result == 0)
throw new Win32Exception(Marshal.GetLastWin32Error());
}
我没有在这里看到鼠标移动方法在第一脱脂读取?: -/ – Cipher 2012-02-02 05:01:08
如果(m.Msg == WM_MOUSEMOVE)只是指过滤器信息是0x0200。这与if(m.Msg == 0x0200) – Corylulu 2012-02-02 05:04:16
相同我也不确定如何在上面的SkeletonFrameReadyevent中使用这些Add,Remove,PreFilter消息。立即尝试: -/ – Cipher 2012-02-02 05:05:21
