Unfortunately, the story is a bit more complicated. The actual value depends on the respective pressure at the two points. If you touch the touch screen very lightly at point A, and rap hard at point B, the value will be close to B. If you apply roughly the same pressure at both points, it will be indeed roughly in the middle. Also, as pressure changes, the coordinates change. So this means that you could probably do something useful with two finger input with the current hardware, as long as you can make sure that one finger is placed before the other, but you'd have to do some research into interpreting the data you get. - Werner -- _________________________________________________________________________ / Werner Almesberger, Buenos Aires, Argentina [EMAIL PROTECTED] / /_http://www.almesberger.net/____________________________________________/ _______________________________________________ OpenMoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
