If you're looking at an IR based solution I've been working on a touch table using IR lasers. They have the advantage of still working quite well in sunlight rooms.<br><br>Here are the lasers I use and am quite happy with so far: <a href="http://aixiz.com/store/product_info.php?cPath=44_27&products_id=67&osCsid=d5b9a3ff99350c797248ca117ed67cfb">http://aixiz.com/store/product_info.php?cPath=44_27&products_id=67&osCsid=d5b9a3ff99350c797248ca117ed67cfb</a><br>
<br>The challenge with your idea would be somehow using a camera to capture the reflected IR in that small box. I can't think of a solution immediately but I'll keep on it. Maybe the use of a chrome ball or extreme fish eye lens on the camera to try and capture all sides of the installation at once.<br clear="all">

<div style="word-wrap: break-word;">Have a look around for spray-on anti-static ESD coatings. That might get you the conductivity you need for capacitive sensing over larger surface areas.<div><br></div><div>Andrew.<br>
