The biggest problem was that the onscreen graphics didn’t keep pace with the gamer’s head movements, triggering a form of motion sickness. Thomas Piantanida, then principal scientist of SRI International's Virtual Perception Program, test drove a prototype in 1993 and came up with a name for the vomit-inducing phenomenon. The headset’s graphical output, he said, lay in the “barfogenic zone”. By 1994, Sega had quietly shelved the project.
