Buying a New Webcam
After experimenting around with my first table revision, I realized that my camera had to go. It was a USB 1.0 connection, and the delay was pretty much unbearable. From the nuigroup forums, it looked like there was two firewire cameras that were commonly used for multi-touch projects. There is the Unibrain Fire-i™ which runs for about $120 and the Firefly® MV for about $300. I got the Unibrain Fire-i. Now that the USB 1.0 is gone and replaced by firewire the delay is almost unnoticeable. Another plus to the Unibrain Fire-i is that it worked on OS X without the Macam driver. It certainly was more expensive, but the upgrade was much needed. If anyone else is interested, I would definitely recommend this camera, but be warned that the lens comes with an infrared block coating that cannot be removed without damaging the lens. I ended up buying a replacement lens, being really careful to note that it did not block IR.
