Re: Fwd: Re: touchscreen calibration again

Hi Lau,

What Bas says makes sense.
Did you check where the points with maximum error are located?

By the way, I wonder whether a uniform point density could help. It
could be harmful to have more points close to the edges and less at the
center...

What do you think?
