Draw with your finger - It would like drawing with your finger on a sensor pad(similar way of writing with a pen on a piece of paper)
In previous touch screens, you couldn't feel whether you clicked or not, but with this new tech, the projections sense the movement of your fingers by going in whenever you touch.
You can actually feel the projections going in, so it can give you the sense of writing even though you are writing with your fingers.
