Three companies have exhibited methods of 3D display without the need for special glasses at CeBIT.
According to I4U News, the Germany Fraunhofer Institute has developed a system that utilises either analog or digital means to adjust the viewing angle of the display and manipulates eye-tracking to allow viewers to view in 3D even while moving around.
An alternative system was offered by another German company called SeeFront. Its optical system is embedded in a panel that is mounted to the front of a screen, which diffracts the light to create a 3D effect, however it requires that the viewer must be facing the screen at all times to ensure a 3D effect.
A wider viewing solution was Sunny Ocean’s display, which combines software and optics to bring 3D visuals to up to 64 perspectives across a room. It is available in 27-inch screen size although apparently 100-inch screen sizes are technically possible.
