Made using PS3 eye webcam with IR blocking filter removed and a new filter that only allows 850nm IR light through. The projector is an Optoma EX525ST DLP Short Throw Projector and is mounted on a custom black acrylic stand made by my co-worker Casey at SparkFun. I’m also using the LLP method using two 850nm lasers and beam splitters to create a horizontal line just barely above the projection surface. The lasers are powered by some cables I made and are connected to SparkFun’s USB Breadboard Power Supply. The surface is clear 1/4″ acrylic with a large vellum sheet taped to the underside. The software used is Community Core Vision and Processing running Memo’s MSAFluid TUIO test slightly modified to allow for smoother TUIO inputs. Obviously this is an early video and a lot of calibration is required. Also the video is choppy and the multi-touch is less responsive than normal since I was running both webcams off my laptop along with dual monitors. I’ll record a better version soon once I have the rest of the case created.

Screen interaction …
Screen interaction looks good. How does your setup look in normal lighting (i.e. lights turned on in office or home)? Can you perhaps post links to some pictures or another video of your multitouch table in normal lighting? Thanks a bunch~
