Francois Vogel and Jonathan Post have created a new way to view 3D cinema without those annoying glasses -- while giving your peepers a massive workout at the same time. Their invention (which has raised a few flags in the tech industry) syncs your eyes with the action on your monitor/screen, basically simulating the technology of 3D active shutter glasses.
How do normal shutter glasses work? Each eye sees a slightly offset view of what's on the screen, which is fused together in our brains to create a unique perception of depth. The lenses of your shutter glasses rapidly alternate the opening and closing of an LCD lens in front of each eye (one eye is blocked by a "shutter" or darkened LCD lens). This syncs in time with the refresh rate of your screen and is controlled via a wire, or through a type of signal (infrared, radio, DLP-Link, or Bluetooth transmitter).
With this invention, your eyelids act as the shutter which means you no longer need the glasses to do the work for you. The system only works on 120Hz monitor displays. Some people are claiming it's all a hoax, because it seems impossible for anyone's eyes to blink at a rate that fast -- and continuously on top of that. Others are saying this technology is entirely possible and that it's a wonderful invention for folks who wear glasses and don't want to double up during 3D movies.
