Glasses-Free 3D Technology Demoed on iPhone 4, Truly Spectacular

Watching 3D videos and playing 3D games on your iPhone/iPod Touch or iPad would really be a treat to your eyes. There have been many attempts before to enable 3D on iOS devices, including few Cydia apps and certain accessories like My3D Viewer. Most of these attempts have either involved glasses, are a bit expensive, are limited and don’t perform that well. Keeping these things in mind, researchers from Engineering Human-Computer Interaction Research Group(EHCI) have developed a way to view in astonishing 3D without the need of glasses.

This new research involves the use of the front camera to detect the head motion of the user that in turn adjusts the display to the point where the user is looking from, making things on the screen get true 3D depth and spectacular effects. If you remember, a similar kind of technology was also rumored to be coming soon on the iPod Touch, but that was just a rumor. This is real, there are a few videos that you may want to watch to believe this and trust me they will really make you want this on your iOS device too.

According to the group of researchers Jeremie Francone and Laurence Nigay;

Head-Coupled Perspective (HCP) on mobile devices allows to create a glasses-free monocular 3D display. It is based on a efficient head-tracker that uses the front-facing camera of the device. We use an off-axis projection in order to adapt the perspective of the 3D scene according to the head’s position of the user. Such spatially-aware mobile display enables to improve the possibilities of interaction.

This is something really very spectacular and a treat for all the iPhone users as this technology could be used in games and other applications. Just imagine playing Angry Birds or Need for Speed Shift in 3D. Watch the demonstration videos below on the iPhone and iPad to understand what this is all about. The Head-coupled perspective technology could be the future of 3D instead of bulky accessories and expensive 3D displays.

What do you think of this technology? Do you think it’ll be soon implemented into games and apps?

Is the Nintendo 3DS Really 3D?

The Nintendo 3DS is the latest handheld console to hit the market, and it’s most remarkable feature is 3D, without 3D glasses.

This is an immense deal, but just how 3D is the Nintendo 3DS, really?

After a little bit of experimentation with one of these gadgets at a local trade show I can say the Nintendo 3DS really is 3D. To a certain extent at least.  The Nintendo 3DS looks highly 3D if you have it at the exact angle. The good news is that the Nintendo 3DS includes an easy to use slider which controls the depth of field of the 3D depth.

Fortunately if you are in a situation where the Nintendo 3DS doesn’t work, you can easily slip it back in to 2D mode!

The 3D does not end at the display.  The Cameras on the Nintendo 3DS can also take 3D images to display on your screen, this is actually a pretty cool feature, and fairly unique (especially at the price).

On top of the 3D features of the Nintendo 3DS, this stunning console has an interior gyroscope for even more engrossing console control in game. This extra level of control comes in extremely useful in the 3D world.

So the Nintendo 3DS really does have true 3D, without needing 3D glasses. but is it worth the cost? The nintendo 3DS costs nearly $100 more than it’s predecessors.  The 3D gameplay is definitely more engrossing, but do we really want to spend the extra cash?

In the end the decision is down to the buyer, if you love Nintendo DSi games then this is the obvious step up. However if you just use your Nintendo DS console for text based games, or brain training games, then you probably will not need the 3D functionality of the Nintendo 3DS.

The 3D funcitonality is definitely unique, and definitely a whole new level of gameplay, however it does not perform too well in strong outdoor light. In most environments however the Nintendo 3DS performs admirably, with an intendely in depth level of gameplay with it’s enthralling 3D capabilities!
