Volume One: Wii MotionPlus Inspires New Controls

Selecting Items Without Looking at the Screen

Iwata

Wii MotionPlus allows you complete control over Link's sword, and you can stop that sword in mid-swing, fire a sword beam, and dash up using the A Button, but another big point is the big change from previous games in the UI for choosing an item.

Aonuma

That's right. As alluded to earlier, in The Legend of Zelda games you have to be able to switch items in a flash.

Iwata

Yes.

Aonuma

Until now, you had to open the item screen and choose the Bow or a bomb, disrupting the flow of the game. And that didn't seem right even to me. But the director Fujibayashi-san and Tanaka-san in charge of UI totally resolved that big problem.

Iwata

Fujibayashi-san, how did you do that?

Fujibayashi

We were using Wii MotionPlus, so I wanted to do something revolutionary even for switching items, and what I came up with was quickly switching items without having to look at an item screen.

Iwata

Item selection without looking at the screen. That truly is revolutionary.

Fujibayashi

Yes. I thought it might be possible with Wii MotionPlus, so after I had a rough idea of it, I talked to Tanaka-san and asked for the impossible. I explained it using gestures, like, "If you do this, then this happens." (laughs)

Iwata

After he laid that on you, Tanaka-san, how did you approach it?

Tanaka

When using the Wii Remote, the most common solution is to choose items with the pointer. But this time, we wanted to select items without using the pointer.

Iwata

That way you make use of Wii MotionPlus's features.

Tanaka

That's right. We tested arranging the items on the screen in a circle, and you twist the Wii Remote Plus like a rotary switch to select an item.

Iwata

You thought of selecting items the way you used to turn a dial to select television channels.

Tanaka

Exactly. But when we tried it out, you can only turn your wrist about 120 degrees, so when choosing one item from about eight, you end up selecting the wrong one a lot. Then we realized that turning your wrist wasn't the right way to go and tried tilting the Wii Remote Plus with your arm.

Fujibayashi

That way, even if you don't look at the screen, the items are at certain angles and you can select them by tilting the Wii Remote Plus. As you play, you remember that, for example, the bow is at the top and your bombs are on the right.

Tanaka

For example, you remember with your body that if you tilt down, you switch to the Slingshot.

Iwata

So you can do it without looking at the screen. I think it was around the time you had just made that system, I remember very well that Miyamoto-san really bragged about it. He said, "Once you get used to it, you can select items with unprecedented speed and without interrupting the flow of the game. It's quite unique."

Fujibayashi

That was the first time Miyamoto-san ever praised me. (laughs)

Aonuma

Huh? The very first time? (laughs)

Fujibayashi

I'd never had that experience before, so I was overjoyed.

Tanaka

Yes. We were giving each other high-fives.

Iwata

(laughs)

Tanaka

That's how happy we were. We were like, "We finally did it!"

Iwata

He even mentioned it to me before it was even finished, so it must have really struck a chord with him.

Aonuma

I suppose so.

Iwata

Tanaka-san, looking back at it now, what struck you the most?

Tanaka

Hmm, it's difficult to pinpoint one thing, but what made me think it went well in the end was something I noticed when we were having game testers look at it. Many playing for the first time thought the remote was for pointing at the screen.

Iwata

They didn't notice that you controlled it by tilting the Wii Remote Plus.

Tanaka

That's right. Using it like a pointer is second nature for the Wii console, so everyone has that preconceived notion. But even if you try to point, you can select items. When that went well, I thought, "Oh, this is good!"

Iwata

The pointing movement syncs with the Wii Remote Plus controller's tilt. So once you get used to it, you realize that it doesn't have to be pointed at the screen all the time, which makes it much easier to play.

Aonuma

Exactly. Another important point is how when the finger icon appears on the item selection screen, there's a string attached to it.

Fujibayashi

That was quite an invention, if I do say so myself. (laughs)

Aonuma

Yes. There's a string attached to the icon, so even if you make a big movement with the Wii Remote Plus, it moves in a circle, but no further.

Fujibayashi

In other words, even if you the Wii Remote Plus is swung all the way out, the finger icon never leaves the screen.

Iwata

Oh, I see.

Aonuma

The first time I saw that, I thought, "What's with this unsightly string!" (laughs) But when I actually tried it out, it felt comfortable. When first seeing screenshots of that string, many people may feel like something is off, but once they play it, I hope they'll realize how comfortable it feels.

Iwata

The items are much more comfortable to choose. You can use familiar items from the series as well as new ones.

Fujibayashi

Take the good old Slingshot and Bow. Until now the sights jumped around and you had to point the Wii Remote to the screen all the time, but not this time.

Aonuma

That's right. You don't use the pointer. You hold the Wii Remote Plus like a bow and use the sites to take aim, so it doesn't waver. That way, when you accurately aim at something far away, it feels incredibly comfortable.

Tanaka

When it comes to the bombs, if you swing the Wii Remote Plus from above, you throw one, but if you swing it from below, you roll it. And you can put a spin on them.

Iwata

You can spin the bombs?

Tanaka

Yes.

Aonuma

But getting it in the UI was pretty hard, because the arrow needs to bend so sharply on the screen.

Tanaka

That's true. The bomb will curve in the direction you twist the Wii Remote, so there's an arrow on the ground showing that direction.

Aonuma

Originally, you bought bombs at shops or picked them from Bomb Flowers growing from the ground, and then you used them, but this time, you can pick them from a Bomb Flower and put them in a bag.

Iwata

You can gather bombs?

Aonuma

Yes. (laughs) At first, I thought, "Huh?! Is that all right?!" but when I actually did it, it felt incredibly natural. I've been involved with The Legend of Zelda games for a long time, so again I'm frustrated that I never hit on that idea before.

Iwata

(laughs)

Fujibayashi

When you store them, they're shooting off sparks. (laughs)

Iwata

They don't explode in your bag? (laughs)

Kobayashi

No. The fire goes out once they're in your bag.

Everyone

(laughs)
