Bodyoke

I'm coining the term right now.

Yes, I know it's not correct. But Karabody sounds terrible and people can't intuit what it means.

So, bodyoke.

Just as karaoke allows someone to be insinuated into a song, bodyoke will allow insinuation into video or a game.

The idea is sensors on the body that will be read by a camera hooked to a PC. A person has to be positioned to match up movement dots on the screen (like movement-based Dance Dance Revolution or action-based Guitar Hero). The first iteration will be akin to learning a dance. Once the movement has been learned, the captured video of the person is melded into a video or videogame where it replaces an existing character or character template.

Future iteration will simply be a person turning 360-degrees in front of a camera. The computer will then model the person and do all the necessary animation.

A similar effect was used in Dead Men Don't Wear Plaid, Zelig, and probably most famously the JFK scene in Forrest Gump.

Here's a Gump clip:
