The simplest way to define this method is that it works as a joystick. The up/down movements of the head will move the mouse pointer Up/Down in the screen and the Left/Right movements will move the mouse pointer Left/Right on the screen. Vertical and Horizontal movements can be executed at the same time by moving the green dot diagonally.
It was the first method implemented by mouseTrap and it is one of the most important because it requires a really small movement ( customizable ) of the head to executes the mouse pointer movements so for people with difficulties for head movements will be easier to control the mouse.


When the clicks dialog is being showed the mapper will look like figure 4 and will accept 4 events. This events will allow the user to select the type of click to perform, Accept the click or just Cancel. To perform each of this features it is necessary to take the green point out of the safe area moving it to the desired acction.
E.g: To Cancel, the green point has to be moved down until it gets out the safe area.
