Not defending anything, but just to remind 60 fps of a pointgrey camera is
not slow. you probably will have a lot of trouble in dealing with 60 frames
trying to cycle through your code every second. Accels and other hardware
sensors are very useful too, and it very good results. But not the best for
3d positioning of a point in space, but excellent at giving the rotation of
that point in space (i.e.: accels, gyros).
