Philips Entertaible: 45 Point Gaming Touchscreen

Wow, big shout out to my buddy John, for showing me this.  Philips Research has developed a multipoint gaming touchscreen that can detect 45 touch points simultaneously that works with fingers as well as game pieces.  Perhaps the most impressive part is that it's all built around a 32 inch LCD screen, so the whole thing is only around 10cm (4 inches) tall.  Another interesting detail of the Entertaible is the technology used to determine touch locations, as it doesn't use any of the 3 most common methods.

The Philips Entertaible, however, is based on a series of infrared LEDs and photodiodes discretely mounted around the perimeter of an LCD screen.

Basically this thing detects finger placement like those obnoxious electronic door chimes they somtimes use in stores.  I wonder what kind of accuracy they can get out of that?
