Project Details

"In this image display system, a large screen is used as an alternative to [head mounted displays]. The sphere is an ideal shape for a screen that encompasses the human visual field because it maintains a constant distance between the eyes and the screen as the viewer's head rotates." 
 
"Ensphered Vision uses a single projector and a convex mirror to display seamless images. The optical system employs two mirrors; a plain mirror, which bends the light so that the viewer can see the image from the center of the spherical screen, and a spherical convex mirror, which diverges the light from the projector in the spherical screen. This optical configuration proves a seamless wide-angle image in a very limited space. The screen's field of view is 270 degrees horizontally and 100 degrees vertically."
