What is "r-zone"

The R-Zone is a portable game console (originally head-worn, later handheld) developed and manufactured by Tiger Electronics. The R-Zone was shown at the American International Toy Fair in February 1995, and was released later that year. The R-Zone was a largely unsuccessful handheld console and would only be manufactured for a short period, before being discontinued in 1997.. Although the R-Zone was not designed to compete directly with any other handhelds, it marked Tiger Electronics' first multi-game entry into the portable electronic game market.

The original R-Zone unit consisted of a headset and a separate controller containing batteries. Each game cartridge contained its own transparent LCD display screen which was projected onto a mirrored surface held in front of the player's eye. It is thought that this original design, including the red color scheme, was designed to capitalize on popular buzz for the Nintendo Virtual Boy at the time.
