The Activator is a full-body motion based video game controller unit released by Sega. It is an octagonal controller unit which sits on the floor and uses infra-red beams to interpret movements. It was revealed for both the Sega Mega Drive console and Sega System 32 arcade system in August 1993. On the Mega Drive, it was intended to act as a more immersive substitute for a standard control pad. In the arcades, it was used for the fighting game Dragon Ball Z V.R.V.S., which used extra sensors for better motion detection.
