N-trig shows off pen input-capable DuoSense multi-touch display

It seems like there isn't a week that goes by these days that we don't see another multi-touch display (homebrew or otherwise), and you can now add one more contender to the growing ranks, with N-trig set to debut its new DuoSense system at the SID International Symposium in Los Angeles this week. This one adds pen input capabilities to the usual array of multi-touch features, as well as the somewhat unique ability for multiple people to use the display simultaneously, which N-trig says makes the system ideal for gaming applications. N-trig also boasts that the technology works on "large format displays," but that apparently maxes out at a not-exceptionally-large 22-inches at the moment. Head on past the break for a video of the rig in action.
