Key Discussion Points and Insights

1. What Is Virtual Reality?

[00:49 – 04:29]

• Trusty Narrator kicks off by teasing kids with a "trip" to China, only to reveal he’s in his bedroom using VR.
• VR explained: It’s a technology that lets you "travel" anywhere by simulating sights, sounds, and sensations through special headsets.
• VR’s uses span from kids’ games (like Roblox) to virtual vacations for adults.

Quote:
“Thanks to VR, you can create sights, sounds, and sensations so realistic you’ll swear you’re there.”
— Trusty Narrator (01:16)

• Iris, the virtual assistant, provides a clear definition:

  “Virtual reality is the use of computer technology to create a simulated three-dimensional world that a person can interact with and explore while feeling like they're actually in that world.”
  — Iris (04:33)

• The term "immersion" is introduced and explained as the feeling of being completely absorbed in a VR world.

---

2. How Does VR Work—And What Are Its Limits?

[04:29 – 06:41]

• Interaction is key; in good VR, you can "pick up a glass of water," though you can’t actually taste it yet.
• The concept of "cybersickness" is explained—when visual delays cause discomfort, similar to motion sickness.

Quote:
“Technology hasn’t gotten that far yet, but perhaps one day.”
— Iris, answering about "tasting" in VR (05:35)

• Even a tiny delay between movement and what you see (just 50 milliseconds!) can trigger cybersickness.

---

3. History of Virtual Reality

[06:41 – 09:36]

• Contrary to popular belief, VR has been around for over 60 years.
• The Sensorama (1962) is showcased as an early VR device, letting users feel like they’re riding a motorcycle through New York, complete with sight, sound, smell, and touch.

Quote:
“Behold the Sensorama. This machine, made by Morten Heilig, let people experience movies through four of their five senses.”
— Iris (07:37)

• Early VR was used primarily by NASA and the military for simulation and training, especially for astronauts.

---

4. Modern Applications of VR

[09:36 – 11:40]

• VR is already in use today:
  • Medicine: Doctors can practice surgeries on 3D models before operating on real patients.
  • Legal System: Jurors view 3D reconstructions of crime scenes.
  • Automotive Industry: Factories use VR to design and test cars virtually, spotting problems before physically building them.

Quote:
“By making 3D models of a patient’s body, they can decide the best way to operate, and then they can practice the surgery over and over again.”
— Iris (10:16)

---

5. The Future of Virtual Reality: The Metaverse

[15:20 – 18:17]

• Iris introduces the concept of the Metaverse: a vast, interconnected network of 3D virtual worlds where people can work, play, and socially interact.
• Trusty Narrator imagines shopping online by walking into a virtual store and trying on clothes alongside friends.
• Avatars are defined as the digital representations people use in virtual worlds.

Quote:
“A place where people can meet up, work and play games together. Kind of like if the Internet of today was 3D and you could live inside it.”
— Iris (16:06)

• The episode notes that while the Metaverse vision is exciting, it's still far off due to both technical and adoption hurdles (only about 2% of the world has VR headsets).

Notable Quotes and Memorable Moments

• On Immersion:
  "The answer is immersion. Immersion means feeling incredibly absorbed. I don’t know about you, but I definitely get that feeling when I’m playing a video game." — Trusty Narrator (04:45)

• On Cybersickness:
  “Scientists have found people will notice a delay even if it’s just 50 milliseconds, which is only about half as long as it takes you to blink.” — Iris (06:14)

• On VR’s History:
  “Wait, that means we’re talking the 1960s. But how can that be? There’s only one way to find out!” — Trusty Narrator (07:08)

• On the Future:
  “That’s like trying to guess what the Internet would turn into way back in 1985.” — Iris (17:36)

• Memorable Moment:
  The Sensorama time-travel visit (07:23 – 08:44), with Trusty Narrator describing smelly exhaust and pizza, and feeling the wind on a motorcycle in 1960s VR.

• Audience Laughter and Group Chorus:
  Lighthearted interjections ("Whoa," "Pee-ew, must be garbage day," "That virtual shirt looks virtually good on you") keep things funny and relatable for kids.

Transcript

[Trusty Narrator]

And now it's time for who's Smarted? Hey there, smartypants. Trusty narrator here. And right now, I am in the third largest country on Earth, about to take a walk on the longest wall on the planet. Are you able to figure it out, smarties? Why I'm at the Great Wall of China in China. How cool is that? But that's not all. I'm also going to visit the giant pandas in the Beijing Zoo. Aw, they're so cute. And now I'm headed to the Forbidden City, which is a palace complex in the center of the imperial city of Beijing. Wow. China sure is incredible to look at. But you know what's the most incredible thing about all of this, smarty pants? I'm not actually here. I mean, there. I mean in China. I'm actually standing in my bedroom wearing some weird goggles that are connected to my computer. Any guesses what I'm talking about? Did you say virtual reality? That's right. Thanks to cutting edge technology called virtual reality, or VR for short, all you or I need to visit anywhere in the world, or the universe for that matter, is a special headset like the one I'm wearing and some fancy software. Thanks to VR, you can create sights, sounds and sensations so realistic you'll swear you're there.

[Audience/Listener]

Whoa.

[Trusty Narrator]

Now, some of you smarty pants may already know what I'm talking about if you play games on Roblox, because a lot of those games can be played in virtual reality. And your adults may know about VR if they've ever taken a virtual tour of a foreign country like I just did to decide if they want to go there on vacation. The tourism business is just one of many industries that have been changed forever by VR technology.

[Chorus/Group Voice]

Woohoo.

[Trusty Narrator]

I'm swimming with dolphins in the Bahamas. Now I'm visiting the Taj Mahal in India. Oh, and now I'm outside Buckingham palace in the UK. All with the push of a button. Today, about 170 million people use VR technology, and over half a billion new VR headsets are expected to be sold by 2025. So now's the perfect time to learn more about it. Like, how does virtual reality work? What was it like when it was first invented? What else are people using it for? And what's virtual reality going to look like in the future? Get ready, smarty pants, because stuff is about to get real. Or so close to real, you won't be able to tell the difference. It's time for another whiff of history and science on who smarted.

[Chorus/Group Voice]

Who'S smarted. Who's smart? Is it you? Is it me? Is it science or history? Listen up, everyone. We make smarting lots of fun. But who's smarted?

[Trusty Narrator]

You know, when I was a kid.

[Sponsor/Advertiser]

The times I learned the most weren't in school. They were when I was building or making something new. I still remember the joy of creating something with my own two hands. That's exactly what Kiwico brings to kids today. With Kiwico, every crate is a chance for your child to tinker, create and innovate. They'll learn the fundamentals of science, technology, engineering, art and math while actually having fun. I love that these projects build skills over time. One month it's learning to design a working bow and arrow, and the next it's building a robot. And what makes Kiwico special is is that these aren't one and done projects. They're built to last, so kids can play, experiment, and keep discovering long after the box is open. Kiwico makes it easy to give your child the gift of curiosity and confidence delivered right to your door. Tinker, create, innovate.

[Trusty Narrator]

When it comes to brand new technology, smartypants, I, your humble trusty narrator, am not the hugest expert. So for our exploration into virtual reality, I've enlisted the aid of my virtual assistant, Iris. That's Siri backwards, by the way. Hi, Iris.

[Iris (Virtual Assistant)]

Hello, trusty narrator. How can I be of assistance?

[Trusty Narrator]

Well, for starters, please tell us your definition of virtual reality.

[Iris (Virtual Assistant)]

Virtual reality is the use of computer technology to create a simulated three dimensional world that a person can interact with and explore while feeling like they're actually in that world.

[Trusty Narrator]

Smartypants, there's a special word for feeling like you're actually part of a virtual world. Is that word immersion, implosion, or indoctrination? The answer is immersion. Immersion means feeling incredibly absorbed. I don't know about you, but I definitely get that feeling when I'm playing a video game, even when it's not in virtual reality. So I can just imagine how absorbed I'd feel if I was.

[Iris (Virtual Assistant)]

The goal of virtual reality is to make you forget where you really are. One way it does that is by letting you interact with your virtual world. For example, with good virtual reality, if you see a glass of water on a table, you can walk over, pick it up, and bring it to your mouth just like you're Going to drink it.

[Trusty Narrator]

So, Iris, how does VR water taste?

[Iris (Virtual Assistant)]

There is no taste because you are not able to actually drink it. Technology hasn't gotten that far yet, but perhaps one day.

[Trusty Narrator]

I've heard virtual reality can cause something called cybersickness. That doesn't sound good. What causes cybersickness, Smartypants? Is it A, when you see something in virtual reality that you're allergic to in real life? B, when there's a delay between when you move your eyes and when your virtual reality world changes what you see, or C, when you catch a cold? From the last person who wore the virtual reality headset, the answer is B.

[Iris (Virtual Assistant)]

When there's a delay between when you do something in virtual reality, like walking, and when you see it happening, you experience something called swimming. This is what causes a kind of motion sickness known as cyber sickness. Scientists have found people will notice a delay even if it's just 50 milliseconds, which is only about half as long as it takes you to blink.

[Trusty Narrator]

That just shows you how connected your eyes and brain are. Smarty pants. True or false? VR is brand new technology that hasn't been around very long. The answer, surprisingly, is false. Iris, how long has VR been around?

[Iris (Virtual Assistant)]

Virtual reality has been around for 60 years.

[Trusty Narrator]

60? Did you say 60 years?

[Iris (Virtual Assistant)]

Yes, 60.

[Trusty Narrator]

Wait, that means we're talking the 1960s. But how can that be? There's only one way to find out. Let's fire up the old teleporter to take us back to the future of technology. Which is when, exactly, Iris?

[Iris (Virtual Assistant)]

1962 should be sufficient.

[Trusty Narrator]

1962, here we come. Whoa. What's that machine, Iris? It looks like an old arcade video game.

[Iris (Virtual Assistant)]

Behold the Sensorama. This machine, made by Morten Heilig, let people experience movies through four of their five senses. If you stick your head through the opening in the front, you'll see a movie that makes it look like you're riding a motorcycle through New York City.

[Trusty Narrator]

Wow. It's kind of like 3D Mario Kart. The pictures all around me. It really feels like I'm riding a motorcycle.

[Iris (Virtual Assistant)]

But it's not just about what you see and hear. Take a whiff.

[Trusty Narrator]

Ew. I smell the exhaust from the bus in front of me. Ooh. And now I can smell the pizza from the pizzeria I just passed.

[Iris (Virtual Assistant)]

What about your sense of touch?

[Trusty Narrator]

I can feel the wind blowing through my hair, and my seat is bouncing from this bumpy street. Oh, I'm very impressed, Iris. This Sensorama machine is very realistic.

[Iris (Virtual Assistant)]

It was way ahead of its time.

[Trusty Narrator]

Any Chance I can go back to the pizzeria and try the pizza.

[Iris (Virtual Assistant)]

No, the only basic sense you can't sense is taste.

[Trusty Narrator]

Of course, we can't even do that with the VR of today. Anyway, I can see why this would get people excited about virtual reality. So what came next, Cyrus?

[Iris (Virtual Assistant)]

The first headsets or head mounted display were invented in the 1960s. And pretty soon the biggest users of virtual reality technology were.

[Trusty Narrator]

Any guesses, Smarty pants? Here are two hints.

[Chorus/Group Voice]

That's one small step for man.

[Trusty Narrator]

If you said NASA and the military, you're right. Hmm. Smarty pants, what do you think NASA wanted to use virtual reality for? If you said flight simulators, you're pretty sharp. What better way to train astronauts to fly the space shuttle than in a virtually identical copy of 1?

[Iris (Virtual Assistant)]

NASA still uses virtual reality today, astronauts can practice controlling a robotic arm through their own movements.

[Trusty Narrator]

Oh, sort of like the Wii.

[Iris (Virtual Assistant)]

Yes. One day, scientists may be able to use this technology to operate instruments millions of miles away on Mars. Wow.

[Trusty Narrator]

I can't wait, Iris.

[Iris (Virtual Assistant)]

Actually, there's no reason to wait, trustee. Virtual reality is already being used in our daily lives.

[Trusty Narrator]

Really?

[Iris (Virtual Assistant)]

For example, did you know doctors can use virtual reality to practice complicated surgeries ahead of time?

[Trusty Narrator]

No way. Did you know that, smarty pants?

[Iris (Virtual Assistant)]

By making 3D virtual models of a patient's body, they can decide the best way to operate, and then they can practice the surgery over and over again.

[Trusty Narrator]

Practice makes perfect, Iris. Where else is VR used?

[Iris (Virtual Assistant)]

I'll show you. Teleport us to a courtroom.

[Trusty Narrator]

Hey, why are these jurors wearing virtual reality headsets? Any guesses, smarty pants? I don't think it's to play Roblox games.

[Iris (Virtual Assistant)]

They're being shown a crime scene in 3D virtual reality. This way, they can visualize how things might have happened.

[Trusty Narrator]

Wow. I can see how that would help jurors make better informed decisions. Anything else?

[Iris (Virtual Assistant)]

Yes. Here's a hint.

[Trusty Narrator]

Hmm, Sounds like a factory.

[Iris (Virtual Assistant)]

It is. An automaking factory, to be precise. Automakers can build a virtual car before building a real one, so they can see ahead of time what problems they might encounter.

[Trusty Narrator]

Wow. Those are some real smarty pants. Right, smarty pants? Of course. That's just what's happening with virtual reality. Now the really exciting thing is, what's going to happen next?

[Iris (Virtual Assistant)]

That I can tell you, trusty.

[Trusty Narrator]

Great. I can't wait to take a tantalizing glimpse of the future of VR right after this quick break. This show is sponsored by Wayfair.

[Iris (Virtual Assistant)]

I am.

[Trusty Narrator]

You don't mean.

[Iris (Virtual Assistant)]

I do.

[Trusty Narrator]

The Metaverse. Metaverse? Metaverse. I've heard a lot of people talking about the Metaverse the these days, smarty pants. What do you think that is? Don't feel bad if you have no idea because there really isn't a right or wrong answer yet. Right, Iris?

[Iris (Virtual Assistant)]

That's true. When most people talk about the Metaverse, they're imagining a huge network of three dimensional virtual worlds all linked together. A place where people can meet up, work and play games together. Kind of like if the Internet of today was 3D and you could live inside it.

[Audience/Listener]

Whoa.

[Iris (Virtual Assistant)]

Or at the very least feel like you were living inside it. Thanks to virtual reality.

[Trusty Narrator]

Okay, Iris, I think you just blew my mind. Are you saying that in the future when I shop online, I'll be able to just walk into a virtual store and try on clothes?

[Iris (Virtual Assistant)]

Correct. Your friends could even join you. Wow.

[Chorus/Group Voice]

Trusty. That virtual shirt looks virtually good on you.

[Iris (Virtual Assistant)]

Or you could just hang out with friends or have a work meeting with everyone's avatar just sitting around a virtual table.

[Trusty Narrator]

Ah, there's that word. Smartypants. What do you think an avatar is? Besides two of the highest grossing movies of all time, with three more on the way.

[Sponsor/Advertiser]

Is it a.

[Trusty Narrator]

A high tech Pen B, a cute robot animal, or C, an image you use to represent yourself in the in cyberspace. If you said the last one, you're right. Experts think avatars are going to be everywhere in the Metaverse. Iris, is the Metaverse going to be like one big video game, like Sims or something else?

[Iris (Virtual Assistant)]

Perhaps. But like you said, it's too early to know exactly what the metaverse is going to look like. That's like trying to guess what the Internet would turn into way back in 1985.

[Trusty Narrator]

Well, either way, I'm excited. Iris, when is the Metaverse going to be here?

[Iris (Virtual Assistant)]

Sorry, Trusty, but we're years away from your metaverse dreams coming true. There's still much more technology that needs to be worked out. Plus, while roughly 200 million people have virtual reality headsets, that's only around 2% of the whole world.

[Trusty Narrator]

Gotcha. Well, while we're waiting, shall we take another ride in the sensorama? Oof.

[Audience/Listener]

Pee.

[Trusty Narrator]

You must be garbage day.

[Iris (Virtual Assistant)]

I'm glad I can't smell.
