Featuring greater interaction between the user and device, this new “touch” experience has been achieved by a combination of different technologies. This article provides an overview of recent advances in touch-screen technology.

I’ve been donig a project with a resistive one for an industrial enviorment and it really sucked… at the end we changed it for some buttons…
Anyway, where should i leave my comment for the free PCB???? xD Nice blog, i enjoy it a lot.
There should be a post today, named free PCB Sunday, just post your comment in it.
