Nintendo 3DS



Volume 1 And That's How the Nintendo 3DS Was Made

Shigesato Itoi Tries Out the Nintendo 3DS

Iwata

First of all, I'd like to have Itoi-san look at a demonstration of the Nintendo 3DS system. We exhibited this at the Electronic Entertainment Expo1in June 2010. These images are for showing how images on Nintendo 3DS look three-dimensional without the use of special glasses.

Itoi

Okay. 1. Electronic Entertainment Expo (E3): A video game-related trade show usually held in Los Angeles.

Iwata

What's showing now is a stereoscopic display of a video of natural imagery taken with two cameras.

Itoi

Uh-huh, uh-huh…

Iwata

And next are graphics of Nintendo characters generated in real time in the Nintendo 3DS system. This is the Circle Pad. You can change the camera angle with it.

Itoi

Oh, wow! It's more interesting this way!

Miyamoto

When it moves, it's totally different, right?

Itoi

Yeah, absolutely.

Iwata

The Nintendo 3DS has a slide switch called the 3D Depth Slider. On the side there. Moving it up and down changes the 3D volume.

Itoi

3D volume… Oh! Wow, like this!

Iwata

You can adjust for yourself how three-dimensional you want the images to appear.

Itoi

It's the concept of 3D volume. Is this something that most devices with 3D elements have?

Iwata

No, I don't think there are any other examples of 3D devices doing this. This was the result of the ideas of multiple people, including Miyamoto-san, during the process of developing Nintendo 3DS.

Itoi

I see… So up until now, the 3D volume has generally been decided by the makers of the images.

Iwata

Exactly so. The makers of the images say, "Let's do it about this much." But each player will have his or her own comfort zone when it comes to the depth of stereoscopy.

Itoi

Yeah, right.

Iwata

What's more, even the same person will desire differing depth of stereoscopy depending on the situation, and think things like, "I want it to be more three-dimensional here," or "Now I want it flat." So we thought we would make Nintendo 3DS so players can choose the depth of stereoscopy, and what's more, instinctively and easily adjust it to each situation.

Itoi

And that's called 3D Depth Slider.

Miyamoto

Right. We were very particular about having the switch be a slide. We thought it was very important that it be intuitive. Digital input—raising or lowering numbers—wouldn't convey it at all.

Itoi

Oh right, I see.

Miyamoto

We made it so players can adjust according to how it feels to them, like "Right now I want it somewhere around here" and "Here I want to go all out!"

Itoi

Can you also adjust the three-dimensionality of the video of natural imagery we saw earlier?

Iwata

No, you can't change the three-dimensionality of something recorded beforehand. You can turn the stereoscopic display on or off, though. In other words, you can only select whether you want it to look three-dimensional or not.

Miyamoto

The images for games are rendered in real time within the system, so adjusting the degree of stereoscopy is possible.

Iwata

Even for 3D movies, the images are all fixed ahead of time, so you can't do this.

Itoi

I see… Do you mind if I turn the three-dimensionality way down?

Iwata

Go ahead.

Itoi

Ahh…mm-hmm, mm-hmm… It isn't very interesting when it's flat.

Iwata

Exactly.

Itoi

Hmm, it really isn't! That wasn't quite what I expected. To be honest, I thought it would be just fine either way.

Miyamoto

Yeah. (laughs)

Itoi

I mean, until now, we've taken something two-dimensional but represented it in a three-dimensional way and augmented it in our imagination.

Iwata

Right, right. We made it three-dimensional in our heads.

Itoi

Yeah. I didn't think that power of imagination was anything to sniff at. That isn't exactly wrong, but when you see this…well, it's much more pleasing. How should I put it? The 3D you imagine and actual three-dimensionality are different.

Iwata

With 3D graphics up until now, you felt a sense of depth when the camera swung around.

Itoi

In other words, the movement makes it feel three-dimensional. But this is three-dimensional the moment you see it.

Iwata

Right. When you actually see it in three dimensions, you're surprised by how much it changes.

Itoi

Um, you know how you showed me a little bit of the demo a little while back? This looks better than that did. Is that because you improved the hardware? Or am I just looking at it differently?

Iwata

Actually, it hasn't changed at all since I had you try it out before.

Itoi

So it's my own internal problem.

Iwata

Yeah. (laughs)

Itoi

I must have been resisting it before.

Iwata

Yeah. (laughs)

Itoi

I was surprised then, but… How should I put this? Maybe I adopted a slightly judgmental attitude when faced with something new, like "Let's see how good this is or not."

Iwata

Oh, did you?

Itoi

Yeah. I was really surprised before, but this time I'm more delighted, more excited—like it's really jumping out at me.

Iwata

A lot of people who tried it out say, "I can really see it!" We're trying to come out with that kind of product, so if that's all that impresses people, we're in trouble! (laughs)

But on the other hand, it seems like lots of people who have tried 3D devices up to now haven't really had a clear experience to make them think, "It really looks three-dimensional!" With this, as a result, lots of people's first impression is "I can really see it!"

Itoi

You can't help but say it. Like "You don't need special glasses!"

Miyamoto

Yeah, lots of people say that, too. (laughs)

Itoi

Well…you know…this is really… Oh, that's Pikmin!2Great!

Miyamoto

Doesn't Pikmin look great? (laughs) 2. Pikmin: A game released for the Nintendo GameCube system in October 2001 and the name of a type of creature that appears in the games of the series.

Iwata

It seems like Pikmin is perfect for 3D.

Miyamoto

I like the way they scurry around.

Itoi

Pikmin is a game with a peculiar 3D effect as if you're getting down on hands and knees to look at something small. Man, I want one of these! I'll buy one, Prez! How much is it going to cost me, Prez?

Iwata

(laughs) Well, shall we close the Nintendo 3DS system and begin our conversation?

Itoi

Oh, right. Please.

Miyamoto

Go ahead.

Iwata

Actually, today I wanted to propose a certain topic.

Itoi

Oh? I wonder what it could be…

Iwata

It's something I haven't even told Miyamoto-san yet.

Miyamoto

What is it?! (laughs)
