How does the Oculus Rift work?
Picture a set of ski goggles in which a large cellphone
screen replaces the glass. The screen displays two images
side by side, one for each eye. A set of lenses is placed on
top of the screen, focusing and reshaping the picture for
each eye, and creating a stereoscopic 3D image. The
goggles have embedded sensors that monitor the wearer's
head motions and adjust the image accordingly. The latest
version of the Oculus Rift is bolstered by an external
positional-tracking accessory, which helps track head
movements more accurately. The result is the sensation
that you are looking around a 3D world.
