Sonys Motion Controller had origins back to 2004 | PS3Blog.net
This tech demo is from a PlayStation Underground Disc, Issue #80 which was from May 1st, 2004. I have shown it to a lot of people back then and they all thought it was very cool.
I still have that disc because that demo was fun. I spray painted a ball neon green so I could try out the demo and it worked great, it tracked the ball very well too. Sometimes it was hard to complete the shape because you couldn’t see where you began.
They have obviously come a long way, as you can see here.
