Default The future of gaming...

Saw this on another forum I read. Don't have a link to the original.

Quote:
STOCKHOLM, Sweden (AP) - Shaking hands with yourself is an amusing
out-of-body experience. The illusion of having your stomach slashed with a
kitchen knife, not so much.
Both sensations, however, felt real to most participants in a Swedish
science project exploring how people can be tricked into the false
perception of owning another body.

In a study presented Tuesday, neuroscientists at Stockholm's renowned
Karolinska Institute show how they got volunteers wearing virtual reality
goggles to experience the illusion of swapping bodies with a mannequin and a
real person.

"We were interested in a classical question that philosophers and
psychologists have discussed for centuries: why we feel that the self is in
our bodies," project leader Henrik Ehrsson said. "To study this
scientifically we've used tricks, perceptual illusions."

It sounded intriguing enough for me to try it, though entering the
laboratory on Monday, I was having second thoughts.

The first props I saw were two kitchen knives, three naked dummies and a
prosthetic hand sticking out from behind a curtain.

"You have the right to say stop at anytime if you feel uncomfortable," said
Ehrsson's colleague, Valeria Petkova, as she rubbed my left hand with
electrolytic gel and attached electrodes to the middle and index fingers.

She assured me I was not in any danger. Still, a nervous tingle rushed
through my body as she placed the headset over my eyes.

In the first experiment, the goggles were hooked up to CCTV cameras fitted
to the head of a male mannequin, staring down at its feet. Through the
headset I saw a grainy image of the dummy's plastic torso. I tilted my head
down to create the sensation I was looking down at my own body.

At that point, it didn't feel very real. But when Petkova simultaneously
brushed markers against my belly and that of the mannequin, the effect
started setting in. As my brain processed the visual and tactile signals, I
had a growing impression that the mannequin's body was my own.

That was good fun, until the gleaming blade of a bread knife entered my
field of vision. Petkova slid it across the dummy's stomach, sending shivers
down my spine and a pulse of anxiety through the electrodes. My heightened
stress level was illustrated by a spike in a computer diagram shown to me
after the experiment.

"Approximately 70-80 percent of the people experience the illusion very
strongly," Petkova said.

Apparently, I was one of them.

The second experiment was more benign. This time my headset was connected to
cameras mounted on a round hat that Petkova was wearing. We faced each
other, extended our right arms and shook hands.

Now that was weird: I was supposed to have the sensation of shaking hands
with myself. The illusion wasn't perfect as I couldn't quite recognize
Petkova's grip as my own, even though that's what the goggles meant to make
me believe.

Perhaps the session was too short. The actual study, in which 87 volunteers
participated, consisted of repeated sessions that gradually provided more
accurate data. The results were published in PLoS One, the online journal of
the Public Library of Science.

The principle finding was that under certain conditions a person can
perceive another body as his or her own, even if it is of an opposite gender
or an artificial body.

"These findings are of fundamental importance because they identify the
perceptual processes that make us feel that we own our entire body," the
study said.

Ehrsson said the study built on a previous experiment known as the "rubber
hand illusion" in which participants were manipulated to experience a rubber
hand as their own.

Charles Spence, a professor of experimental psychology at the University of
Oxford, said the Karolinska study was a "step up" from other research on the
subject.

"This goes beyond other recent studies, where you've taken ownership of
rubber hands and rubber legs," said Spence, who was not involved with the
study.

His only concern was whether there might be any lasting effect on
participants.

"The questions is what happens if you did it much longer? If you were in
there for days and weeks. Would it be like something out of Total Recall?"
Spence said, referring to the 1990 Arnold Schwarzenegger science fiction
movie about a virtual vacation that turns into a nightmare.

Ehrsson suggested the findings could be applied in research on body image
disorders by exploring how people become satisfied or dissatisfied with
their bodies. Another possible application could be developing more advanced
versions of computer games such as Second Life, he said.

"It could lead to the next generation of virtual reality applications in
games, where people have the full-blown experience of being the avatar,"
Ehrsson said.
Edit: I thought about this some more this afternoon. Though it would create some kickass games (Welcome to the Holodeck!), I think as soon as the hardware becomes common and someone writes a porn routine we could see a new addiction as strong as any narcotic.

Man, image playing survival-horror games or first person shooters with this.

Jesus. I wish I saw this about a week or two ago - it's given me a brilliant Idea for what I could've used for my 202 Mediatised Theatre Assessment. Shame it's next friday.

Oh, I'm doing a Theatre Degree, specialising in Video/Audio Performance. Projectors, Cameras, Recorded/Broadcasted Sound etc. Wooster Group style stuff. I just wrote a ridiculously postmodern piece (to be performed next friday) where the 8 cast members are actually 8 audience members, being controlled through headphones, by 8 more audience members using microphones going off a script they're given when they come in.

This would've been some good inspiration.
