Re: Touchpad - multiple points of contact?

Synaptic touch pads can figure out multiple points of contact (but
normally the driver or hardware just throws away all of the extra
points). Try looking into the synaptic datasheets and code for the
synaptic Linux drivers.

I don't know of any touch screens which allow multiple points of
contact.

You will need most probably need to look into custom hardware. Lots of
laptops have synaptic touch pads and it might be something you could do
with them.
