Sega Activator (training video)

Oh, damn! I totally missed this one when I was a kid. The Sega Activator: an early-90s pseudo-futuristic controller for the Mega Drive (Genesis in the USA) which replaces switches with infra-red beams and lightdiodes. Probably it was just a response to the Power Glove by Nintendo? Anyway, no surprise that represented a commercial failure: it looks like more an unfinished interaction design prototype than a ready-for-selling product.
SEGA was deeply involved in experiments about gaming interaction during the 90s. I sense that this would have been a good thing, but it wasn’t supported by an, equally, intelligent marketing strategy.
Anyway, I wonder why the Angry Video Game Nerd didn’t ever spent a word about.
