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

Question

I got the code to move the mouse cursor from this question.

My project involves using face tracking to move the mouse cursor, but the face cannot move too much. How do I adjust the sensitivity of the movement, as in the face need only to move a little for the mouse cursor to move a lot, like adjusting the mouse sensitivity in the windows settings.

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.

I assumed that tracker value is linear – Can Guney Aksakalli Dec 21 '15 at 13:26
Would you mind elaborating on it a little bit more? I don't really understand it. The `moveCursor()` method that I use accepts the center of the face as a `Point`. Do I replace value with `point.X` ? – Edwin Dec 21 '15 at 13:53
That example is about clipping rectangle. You need to do `Cursor.Position = new Point(x, y);` in order to change cursor position. – Can Guney Aksakalli Dec 21 '15 at 13:59

Just use a factor to adjust the transformation from face movement to cursor movement.
