Let me introduce myself, my name is Stéphane, I am quadriplegic, that is to say that I am paralyzed in all four limbs. My disability therefore prevents me from being able to use a computer like everyone else. Currently to be autonomous in computing, I use what is called a Tracker Pro.
To schematize the operation, it is a reflective pad which is placed on my forehead, on my computer the tracker is positioned like a webcam, but which captures infrared. When I move my head the pad is in contact with the tracker and therefore moves the mouse cursor.
This system works very well the problem is that it is no longer developed! So I’m afraid that mine will break down and I’ll end up with nothing. So I try to anticipate things and be able to try to create my own tracker!
