>The mouse takes pictures of the surface, and uses DSP to determine how the pictures move with time (and therefore how the mouse has moved). It can do this only by finding "features" in the pictures, and tracking their motion.
That explains why when I move away a little bit from that surface, when it happens, that the mouse starts to work better. As, it hasn't took a picture of that new surface yet. I never saw it like that. Thanks for the reference
>If you have a perfectly smooth, uniform-colour surface, there are no features to track and the mouse goes haywire. The only reason your mouse worked at all on the solid black surface you were trying is because of roughness and imperfections at a small or microscopic scale, and/or surface dust.
Yes, a binder material is usually rougher then the aborright.
>If you have a geometric pattern that repeats on various scales, there's a chance the mouse could interpret a picture of a second feature as a motion of the first one, causing the cursor to jump.
That seems to explain the case.
