So far, I’ve tried to find a good way to make a thin multi-touch surface but got no solution.
So, I make my own and would like to share it with community users.
Instructions are here
The above instruction guides you to make an 8x8 thin multi-touch surface.
It’s a part of my OpenMT project (http://openmtproject.sourceforge.net).
My reason of starting this project is posted here: http://www.touchuserinterface.com/2011/01/working-on-openmt-first-announcement.html
* The instruction as well as OpenMT project are at the very early stage. if you have any question, comment, feel free to post it to this thread or one of OpenMT forums (http://sourceforge.net/projects/openmtproject/forums)
