GDC might be winding down, but we'd be remiss if we didn't catch up with Forth Dimension Displays, the Kopin subsidiary responsible for all those little microdisplays inside your camcorders and, we're told, specialized military gear. While neither of those are terribly exciting to consumers, the outfit's latest concept is. Similar to last year's E3 demo, the company's new rig is built to highlight the kinds of use cases it would like OEMs to build using its microdisplays. The above jury-rigged setup above consists of a helmet rocking two of the company's SXGA (1280 x 1024) microdisplays which are in turn connected to back-mounted drivers which are then attached to your run-of-the-mill gaming PC. But unlike previous endeavors, when head-tracking happened in the helmet, this year we've got a plastic gun stuffed with an air mouse which controls onscreen movement. It's admittedly hacked together and certainly not flawless -- the cursor tended to bob upwards in our time with it -- yet very immersive and an amazing way to frag combine soldiers in the trenches of Half Life 2. But don't take our word for it, ogle at the gallery below, or watch a video of it in all its glory after the break.
