In 1982, Sega's arcade video game SubRoc-3D came with a special 3D eyepiece,[REF] which was a viewer with spinning discs to alternate left and right images to the player's eye from a single monitor [REF].
Sega released the SegaScope 3-D for the Master System in 1987 for Japan and in 1988 for North America, where it was the first known electronic device to use LCD Active Shutter glasses.
