Idea #1 - Jake For this idea we will use sensors to make large buttons. These buttons would each have a corresponding direction. When the button is held down the mouse will move in that direction and when released it will stop. We can also have two buttons that will act as the left and right click buttons. With our design we can specifically change the problems that the original concepts on the market had to match our clients needs.
