For the human body tracking, we had to re-think how to approach
development for something of this nature. There is a reason why this
level of technology or this level of innovation hasn't really existed
before. And that reason is, because if you think about it, traditional
heuristic-based programming is a world of digital land. It's zeros and
ones. It's yes and nos. It's trues and falses.
real world, the world of humans, the world we live in is an analog
world. It's a world where it's not about yes and no, it's about maybe.
It's not about black and white. It's about gray. If you think about it,
to understand and track humans - let's just think about joints on the
human body. You have several different joints. Now multiply that number
by the degrees of freedom that each one of those joints has. Multiply
that by the different proportions of the human body, from the kid to the
adult to the slim person to the not so slim person.
Prof. ISBISTER: Yeah. I think that also if you think about the
emotional components of movement, I think about things like modern
dance, or just how little children like to express themselves through
how they move or skip around the room, there's a lot of leeway for what
you might call abstracted movement games or activities where it's not
necessarily mimicking a real world motion or action, but you're giving
people an excuse to move in a way that changes how they feel that may be
even more abstract than bubbles. You know what I mean? Just be little
swishes of color and sound and...
Prof. ISBISTER: ...be all about the emotional experience that happens as a result.
FLATOW: And the game or whatever you're interacting detects your emotional state.
ISBISTER: Exactly. Yeah, we're actually working with a woman who's
analyzing some video we did of people playing Wii games. And she feels
like -she's a certified Laban movement analyst, which is a style of
dance notation. And she's pretty sure that she can detect when people
are frustrated with the movement they're doing from their posture. So
we're trying to identify what those cues are because our thinking is,
well, wouldn't that be great if we could feed that back into systems
like this and detect when somebody's kind of had it with the game
mechanic from their posture and how they actually execute the move.
