NEC has developed a projector system that lets people playing computer games
bob and weave in front of a large display鈥攚hile still watching the best
possible 3D image. Most 3D images can only be viewed either from a fixed
position or with special goggles. But NEC鈥檚 system bounces infrared light off
the player鈥檚 eyes to work out the person鈥檚 position. It then uses this
information to adjust the images fed to the left and right eye channels of a
lenticular screen鈥攁 device incorporating thin vertically elongated lenses
in front of the screen that steer different parallax images to each eye. 鈥淥nly
one person can use the 3D screen at one time,鈥� says senior researcher Masao
Imai. 鈥淏ut it takes the burden of using goggles off the viewer.鈥�
