Virtual Boy was the first video game console capable of displaying stereoscopic ‘3D’ graphics and is marketed as a form of virtual reality. Virtual Boy creates the illusion of depth on the screen through an effect called parallax. Like a head-mounted display, users can look through a neoprene eyeshield on the front of the machine and see a monochromatic red image through a goggle-style projector. The display consists of two 2-bit (four shade) monochrome red screens of 384 × 224 pixels and a frame rate of approximately 50.27 Hz. It uses an oscillating mirror to transform a single column of 224 red LEDs into a full field of pixels.
