Multi-Touch Research Platform (Lancaster University, UK)
first, thanks a lot for all the inspiration and helpful information that can be found on these pages! Finally I managed to put together some more detailed information about the multi-touch table we built. The design is quite flexible and it can be used with either DI or FTIR. It features the following components:
<ul><li>91x57cm surface (107cm diagonal, 16:10 aspect ratio)</li><li>Toshiba TDP‐EW25 projector (1280x800px)</li><li>Point Grey Firefly MV camera (640x480px, 60fps) with wide-angle lense</li><li>Infrared illumination (850nm)</li><li>Bosch Rexroth aluminium frame</li></ul>
just updated the technical report (http://eprints.comp.lancs.ac.uk/2215/) - it now includes a description of the new DSI setup, using:
<li>EndLighten acrylic sheet with an IR LED ribbon around its edges, and on top a</li>
<li>rear projection acrylic sheet, which provides a better touch sensation and is longer lasting then the previously used polyester film</li>
what material is your surface, I like your table so I think next time round i will use your guide, But I have allready got my opal30(80% transperant) acrylic, Do you think this will work
we player around with our mirrors, out box is in two peices one for a base which connects two a a top, will try to post pics. But about that when i was presenting around 20 mins before the top snagged on my blazez so then it slipped causing the mirrors to move.
