How to build a Multi-Touch surface

Step 9 Package it

 At this point you should now have a fully working Multi-Touch surface.  If you are simply building a development environment then you can probably stop here.  But if you are planning on deploying the surface to a production environment, then you will need to have some sort of enclosure.  The enclosure can be designed however you want, but you must ensure that you have the proper angles and space to project the image and to pick up the entire surface on the camera.  Additionally, proper ventilation is essential since the projector and computer can get quite hot in an enclosed space.

I will add additional steps with detailed plans of my enclosure once I have finished building it.

Good luck!

if you were to do an "Open Air" construction, would there be issues with false readings from the camera from other IR sources? Like say on a stage with lots of different colored moving lights?

I have an idea...

It depends on your method, if you use FTIR, not as much. Other methods like DI or DSI, yes
