The 3DS's Glasses-less 3D explained... Maybe.

I don't know how many people are like me out there, but when I saw that Nintendo was making a new handheld, and that it would be 3D capable, I thought it would be pretty stupid having to wear 3D glasses to play a handheld. Hell, I think its pretty stupid having to wear 3D glasses to play home consoles. But then Nintendo dropped news that - to me - was bigger then the actual 3D news: There would be no glasses to wear. Glasses-less 3D sounds much better then having to wear goofy glasses around when you whip out your device on a bus.

Ahhh, Remember these 3D glasses anyone?

Again, if you're like me, you probably saw that and thought "how in the hell will they pull that off?" Well, I'm here to tell you guys some of the ways that they could do this.

1) Face Tracking

This method works similar to how the Wii's motion tracking works. A camera on the system, like the DSi's in-facing camera, would track the position of the players face. If the console did this, it could adjust the image on-screen and give the illusion of depth. There is one problem with this system though. This would take quite a large amount of processing power. If we're lucky though, recent rumors will be true and Nintendo will be using the NVidea Tigra chipset and will give the system some extra power to work with.

2) Gyro-sensor

This is a feature many may be familiar with because of the iPhone and the iPod Touch. instead of face tracking, the system would alter the image on screen judging on how you hold the system. this could also allow publishers to add in waggle to their games, so this is an option that i really hope Nintendo DOESN'T go with.

3) Parallax Barriers

Don't worry, I'll explain it. What this is - in a nutshell - is having the glasses built into the screen. For normal 3D to work on a 3DTV you have to wear the goofy glasses. These goofy glasses receive a signal from the tv that darkens one of the lenses slightly and gives the screen a different perspective, essentially changing what your eyes see. With Parallax Barriers, the screen changes and in effect alters what each eye sees, giving you a true 3D effect. This is probably what Nintendo will use in their new console. the only downside is that the Parallax barriers make the screen somewhat less light, so the backlighting will not be as bright.

Will the new iteration of the DS hold the same shape as its predecessors?

Only Time will show what the 3DS will be using to display its 3D graphics, and I'm hoping its either Face Tracking or Parallax Barriers. All will be shown at this years E3, and I know that myself and a lot of other people are quite excited.
