3D Display without Glasses using Eye-tracking exhibited at CeBIT 2010

Quote:


Many believe that 3D in the living room will only succeed if we do not have to wear glasses to see the 3D images.
The Germany Fraunhofer Institute is demonstrating an interesting 3D display solution without glasses at the CeBIT 2010.
The auto stereoscopic display is using eye-tracking to allow viewers to move around fairly freely and still view perfect 3D. The system is controlled by contact-free gesture. The Fraunhofer HHI institute is showing two such 3D displays at the CeBIT 2010. The analog 3D display uses mechanics to adjust the images to the viewing angle; its picture quality is the highest now achievable anywhere in the world.

How would such a system handle more than one viewer? or would it only be good for techno-obsessed lonely people?

It does say "viewers."

At the Special Next Level 3D' HHI is showcasing two autostereoscopic systems - one analog and one digital. Both display use eye-tracking to allow viewers to move around fairly freely and still view perfect 3D. The system is controlled by contact-free gesture. The analog display uses mechanics to adjust the images to the viewing angle; its picture quality is the highest now achievable anywhere in the world. The digital display uses electronics to adjust the viewing angle. It is highly robust, and, what's more, keenly priced.

"The auto stereoscopic display is using eye-tracking to allow viewers to move around fairly freely and still view perfect 3D." IMO that sentence doesn't unambiguously say more than one viewer at a time. We need more detail.

FYI, here's a 2006 paper discussing multi-viewer autostereoscopic display research.

This link from May 2009 specifically mentions multi (three)-viewer capability for a 3.5" QVGA mobile display.

Too bad Fraunhofer chose to say so little about what they're showing at CeBIT. But I'm sure additional press releases will be forthcoming.

It looks to be an "extension" of their iPoint 3D system (contact-less tracking):
