We received 4 samples of rear projection screen from Teknilux in Sweden. Eventhough the black sample had a very nice image (a bit better then the other 3), it was totally useless with the silicone rubber sheet. No blobs at all. The 3 other samples worked very well. But the material is less sturdy...

We ordered a new camera for our research. It's the Unibrain Fire-i™ Digital Board Camera. And this baby is sweet. After having thoroughly tested the Philips SPC900NC, we definitely wanted to test out a firewire cam, because of the general knowledge of a firewire cam being faster then a USB cam....

We have shipped our first orders to the States and within Europe. We got more orders for these silicone rubber compliant surface overlays, so we will be busy with producing them the upcoming days.

Today we ordered a nice firewire camera for us with 2 lenses. Hopefully it will be arriving somewhere next week so we can do some serious testing with that baby. I'll be putting more details here lateron.

Instead of using FTIR as a method for vision based multitouch, you can also use a method of flooding the acrylic surface from the back with an IR illuminator like Microsoft does with their Surface. We created our own IR illuminator by bundling a certain amount of IR leds close to eachother. We did...

Because of special requests another movie of the game Starcraft being played on our multitouch display. Thanks to Peter (Kwissus) for recording and uploading the movie.

I posted a movie, some time ago, about Peter playing Starcraft on our multitouch display. But basically this wasn't multitouch, because it wasn't multiple input at the same time. Basically what Peter did, was use a script that translates every fingerdown on the screen into a mouseclick. But...

Today Peter disassembled a TFT monitor to see if it was suitable for a new multitouch project, where we use a TFT to display the image, instead of a beamer with a projection screen. The Viewsonic va903b was not suitable, because the FFC cable was not long enough. Theoretically it could have been...
