Homemade Multitouch Display: a mini guide is coming

I know that my Multitouch Display page has been left alone since I wrote it, with no updates even while I was anyway going on with my multitouch work and tests. In addition, when I write something on the multitouch matter, I'm assuming that everybody knows a lot of things, quite all I've learnt on it until now and I know that is not so useful. On the other side some of you rightly wrote me saying "why you don't give further and detailed informations on the construction, the components used etc.?".

I know that there are already tons of informations on the internet on this subject and there are some very good information depots as well. One of the best is the NUI Group wiki and, of course, the blogs of his users (thanks to DzHiBaS that aggregated them). But, in my opinion, there is still the need for something that may be a more or less complete walkthrough in the theory and the construction of those displays, like it is the how-to guide by Gravano that, unfortunately, was not updated lately with all the great improvements he made.

For all those reasons early this week I started to update the Multitouch Display page...and not only! While writing I reealized  all those reasond and I decided to try to explain more clearly and starting from the beginning the whole story, aiming to reach the goal to put up together a quite comprehensive homemade multitouch guide.

Obviously this is not aiming to be "the ultimate guide" because I played just with FTIR setup and, in addition, my experience is limited just to my project and to the solutions and materials I used. But, anyway, I tried to put together all I know, I experienced and I read on this subject so I can surely say that, hopefully, this will be the best I can do.

Of course this is still a work in progress: there are already three pages to look at but there are some sections that  still need to be written. Anyway, I really hope that at least anybody who is approaching for the first time this fabulous world may enjoy it and find it useful for its multitouch work.

I'll really appreciate any comments and suggestions you would post to enrich this guide and, why not, to correct any mistake in it. It could be a good tools for everybody or at least a good starting point.
