A Series First Driver's Perspective

Iwata

And this time, you can control your kart by tilting the Nintendo 3DS system. It has gyro controls.

Yabuki

Yes. First, Konno-san asked if we could use the gyro sensor20 for something. By chance, the programmer who had worked on the wheel controls for Mario Kart Wii joined the team about that time, so we decided to try to do controls using the gyro sensor.

Iwata

For Mario Kart Wii, the accelerometer21 in the Wii Remote controller detects how fast you turn the wheel. 20. Gyro sensor: A measurement device.

21. Accelerometer: An electrical circuit element that can detect changes in speed. The accelerometer in the Wii Remote™ controller can detect the rate of acceleration in three dimensions.

Konno

According to the programmer, gyroscopic controls are enhanced. A programmer who really loves cars worked on it, so he paid a lot of attention as he made adjustments.

Yabuki

That's right. And while we were making adjustments, we put in the first camera from the driver's perspective that has ever appeared in Mario Kart.

Iwata

Come to think of it, it is the first time in the Mario Kart series that we have shown the game from the driver's perspective.

Yabuki

At first, it was the usual view in which you can see everything, but we made it so if you tilt the console, you turn the wheel. But it didn't feel right, so we were like, "Well, how about changing the camera?" Of course, the design team asked if it was really all right to do that.

Iwata

Did they say, "That isn't Mario Kart!"?

Konno

Yeah. (laughs) If you switch to the driver's point of view, then you can't see the character you're playing. And suddenly the image of the wheel is up close. They said, "We didn't make the image of handle with that in mind!"

Iwata

They modeled it without any idea it would be enlarged.

Konno

They said, "It'll take some time to make a high-detail one. Is that all right?" By the way, in replay mode, you can change the camera, so you can use the normal camera when you race and then switch to the driver's view just for the replay.

Iwata

If you're driving with it set to the driver's viewpoint, is it hard to tell when you hit another kart?

Yabuki

No, it's all right. But there was a problem of not knowing what happened when a shell hit you.

Iwata

How did you solve that?

Yabuki

We decided to pull the camera back when you get hit. Then it switches right back to the driver's viewpoint.

Iwata

Ah…

Konno

And when you go over a banana, you spin. When that happens from the driver's point of view, you might get dizzy, so the camera pulls back and just the kart spins.

Iwata

I see. I think the players will get along with it just fine, but whether you contrive it like that or not makes quite a difference. It's important, but it's the kind of thing that's easy to overlook.

Konno

At first, we didn't think twice about having the screen spin. But after one race, we got dizzy (laughs), so we adjusted it.

Yabuki

We didn't plan on using the gyro sensor at first, but people who are accustomed to Mario Kart say it is new and refreshing. I really hope people will enjoy the new perspective.

Konno

Also, when you battle online, you can tell when your opponent is playing from the driver's perspective—like how the wheel mark appeared for Mario Kart Wii—so please, check that out.

Iwata

You've made something challenging and fun!
