Moving Mouse Cursor Programmatically

How to move mouse cursor using C#?

Take a look at the Cursor.Position Property. It should get you started.

private void MoveCursor()
{
   // Set the Current cursor, move the cursor's Position,
   // and set its clipping rectangle to the form. 

   this.Cursor = new Cursor(Cursor.Current.Handle);
   Cursor.Position = new Point(Cursor.Position.X - 50, Cursor.Position.Y - 50);
   Cursor.Clip = new Rectangle(this.Location, this.Size);
}

How to simulate mouse cursor movement in C++

You will need to gradually progress your mouse a little bit at a time. Consider, for example the following pseudo-code function:

def moveMouse (endX, endY, stepCount, stepDelay):
    GetCurrentPosTo(startX, startY);
    for step = 1 to stepCount
        currX = startX + (endX - startX) * step / stepCount
        currY = startY + (endY - startY) * step / stepCount
        SetCurrentPosFrom(currX, currY)
        DelayFor(stepDelay)
    endfor
enddef

This calculates the current position (within the loop) as some fraction of the journey from (startX, startY) to (endX, endY), adjusting for the number of steps you wish to take.

So using a stepCount of 100 and stepDelay of ten milliseconds, the mouse cursor would smoothly move over the period of a second.

There could be other possibilities such as moving the cursor at a specific speed rather than taking a specific time, or specifying a minimum speed and maximum time to combine both methods.

I'll leave that as an extra exercise. Suffice to say it would involve the same method of moving the cursor a little at a time rather than just setting its position to the final value immediately.

Programmatically move mouse cursor with adjustable 'speed' of cursor movement

The measurement from your face tracker would create a measurement value from the range [low1, high1]

Your Cursor.Position.X would take a value between zero to screen width. Lets notate this range as [low2, high2].

You need to assign Cursor.Position.X such as:

low2 + (value - low1) * (high2 - low2) / (high1 - low1)

The range you define as [low2, high2] will determine the speed of the movement. Shorter range will move the mouse faster.

Move mouse while holding a Key

I think you can use Keyboard.IsKeyDown(Key) method, so you can increase the position of mouse in the direction you want while the key is still down.

For MSDN Reference :

I hope it helps you, good luck !

Moving mouse cursor in Windows Forms

the Form your code is on has a Cursor property. That's not what you want to access.

Instead fully qualify the type, as the error indicates:

System.Windows.Forms.Cursor.Position
