i tried this one but the result was horrible, the drawn lines were being created randomly and all lines were changing in size everytime. I am have the same problem as that user who commented on the vid.
I did exactly what was said in the vid.
I am not sure what I did wrong and he missed to explain?
besides, what i am really seeking to do is not a free-style line drawer (compare it to pencil in Windows's Paint) , but a strict straight-line (= like the Line tool of Windows' Paint), where you press (or click) on the board and move your finger to somewhere else by holding the mouse, a line would be created but it would move with your finger as if it some stick fixed at the origin point, so when you move your finger(or mouse) around, the straight line would move as if it's an "hour hand" of the clock, all this along you're holding the mouse.
So when you go further, the line just becomes longer, and you move the mouse around, the line would just rotate. In other term you can't draw circles and other shapes with that tool, just pure straight lines.

Doesn't that mean that it would only work on pc and never on iOS? if so, how it makes work with touch?
