📖 课文原文 · The Power of Virtual Reality
Paragraph A
People have talked about the possibilities of virtual reality since the mid-1990s.
In this interview, Jeremy Balinson, Director of the Virtual Human Interactive Lab at Stanford University, explains how these possibilities are now becoming real.
What's the difference between watching a video and wearing a VR headset?
The difference is what psychologists call embodied cognition that is, we learn by doing.
For a lot of the most important learning events in your life, you actually did something, you walked somewhere or felt something.
Similarly, virtual reality is active, not passive.
You learn in ways that people have been learning for hundreds of thousands of years by having
Paragraph B
an experience.
Our lab studies have shown that, in general, the brain tends to treat a VR event in a similar way to an actual event, so there's a difference between performing an event in a traditional video game and doing it inside VR.
You've said that VR can help athletes.
What's an example of that?
We demonstrated in the 2014 NFL season that VR could help quarterbacks by improving their decision-making accuracy and reducing their reaction times.
Carson Palmer is one of the earliest adopters.
VR gave him a tool he could use to learn the plays better.
Carson had a system in his home for just a couple minutes a day after he'd wake up.
He'd go over his plays and mentally practice what he was going to do.
Paragraph C
It was as though he were actually on the field, but he was in his living room, getting extra practice.
Since then, VR has been used by teams across many sports.
The German National Soccer team, among others, uses it in their practice quite often.
Explain how VR avatars can improve video conferencing.
Video conferencing is good for some activities, but it's not good for an important meeting where intense decisions have to be made.
One reason is the eye contact problem.
If you look at the camera on the top of your laptop, you don't see the other person.
Conversely, if you look at the other person's image on your screen, you're not looking at the camera.
Psychologists have shown that very small changes in things like eye contact, body space
Paragraph D
or posture, alter the way conversations flow.
With VR avatars, you can control things like body position and eye contact in a way you can't do with video conferences.
You have said that VR can help save the planet.
How can VR raise awareness of environmental issues?
One example is an experiment on the island of Iskia and Italy.
Iskia is a marine site that scientists have been studying for decades.
Carbon dioxide is destroying its coral and degrading the food web.
I can't bring the entire world to Iskia to show how CO2 degrades ecosystems, but with VR, I can bring Iskia to people.
So, we produced a seven-minute journey that shows how all the oceans will look in about 50
Paragraph E
years, based on this one site in Iskia.
Using this VR model, people get to be scientists.
They explore the effects of CO2 on various species in the ecosystem, and learn by doing.
What about the downsides of VR?
For example, using it to create violent video games.
The way I think of VR is that we should use it for things that we can't do in the real world.
You should use VR to go to the moon, or try becoming someone else.
But you shouldn't do things that you wouldn't do in the real world.
In your opinion, will VR change how we interact with other people in the real world?
VR is a tool, just like any other media, but it has a different impact on how we perceive information.
Paragraph F
That's because you're using your body and it's completely immersive.
It's a big jump in the history of media, but I don't think it's going to change who people are.
I think we will continue to be the same humans that we have been on the planet for quite some time, and I, for one, am glad of that.
The interview was edited for length and clarity.
