The researchers have developed a ball-shaped VR display that supports up to two users at a time, using advanced calibration and graphics rendering techniques that produce a complete, distortion-free 3D image even when viewed from multiple angles.

Most spherical VR displays in the market are capable of showing a correct image only from a single viewpoint, said lead researcher Sidney Fels, an electrical and computer engineering professor at UBC.

Globe - Illusion - Angle - Fels - Users

"When you look at our globe, the 3D illusion is rich and correct from any angle," explained Fels. "This allows two users to use the display to do some sort of collaborative task or enjoy a multiplayer game, while being in the same space. It's one of the very first spherical VR systems with this capability."

The system, which the researchers are calling Crystal, includes a 24-inch (600 millimetre) hollow ball-shaped display. The display surface was custom-made to specifications in Ottawa, while four high-speed projectors and one camera used for creating the images, calibration and touch sensing were purchased off-the-shelf.
