3D
Jean-François Boismenu sent me a link to a Technology Review article that discusses emerging 3D technology from, of all people, Microsoft:...a new type of lens developed by researchers in Microsoft's Applied Sciences Group could help make glasses-free 3-D displays more practical.
The new lens, which is thinner at the bottom than at the top, steers light to a viewer's eyes by switching light-emitting diodes along its bottom edge on and off. Combined with a backlight, this makes it possible to show different images to different viewers, or to create a stereoscopic (3-D) effect by presenting different images to a person's left and right eye. "What's so special about this lens is that it allows us to control where the light goes," says Steven Bathiche, director of Microsoft's Applied Sciences Group.
...Microsoft's prototype display can deliver 3-D video to two viewers at the same time (one video for each individual eye), regardless of where they are positioned. It can also shows ordinary 2-D video to up to four people simultaneously (one video for each person). The 3-D display uses a camera to track viewers so that it knows where to steer light toward them. The lens is also thin, which means it could be incorporated into a standard liquid crystal display, says Bathiche.
That's quite interesting, and it's worth watching to see if they can enhance the tech in the future to accommodate more viewers.
Like I've said many times, 3D is going to take over the world, but not while we have to wear glasses.
