Sorry, did I say 6mm wide? I was inaccurate. The objects should be 8mm wide.
It might well work with less, but I'm reading from the design specifications which describe use of stylus, so it would be better to use 8mm width. Or do a whole lot of testing to be sure. http://wiki.laptop.org/go/XO-4 http://wiki.laptop.org/images/0/0c/CL4_Hdwe_Design_Spec.pdf "At least two simultaneous touch points are supported, with additional simultaneous touches supported in some interface layouts. The touchscreen detects fingers or a soft-tipped stylus, as long as the stylus has a diameter of 8 mm or larger (measured within a mm of the end.)" -- James Cameron http://quozl.linux.org.au/ _______________________________________________ IAEP -- It's An Education Project (not a laptop project!)
