I'm always on the look out for pieces of digital innovation but this one really did blow me away when I saw it.

I'm not a big fan of 3D avatar for me was meh... and the constant barrage of films since that are in 3D don't really interest me at all. Add to that the current fashion for 3D TV - after all who would want to see the Jeremy Kyle show in 3D?

There are a few 3D things that I do think are amazing though:

1: Nintendo 3Ds, have to admit I thought it was just a gimmick until I tried one at the recent Gadget Show Live 2011 at the nintendo stand and the 3D as well as the system itself really blew me away together with not having to wear 3D glasses the effect was really something special.

2: 3D gaming building on that 3D I saw with the 3Ds I headed over to the 18+ area of the gaming section to try out some of the new 1st person shooting games. The 50in 3D TV mixed with the PS3's graphics was mind blowing and definitely gets my vote as a worthwhile use for the recent 3D trend. The only problem is you still have to use 3D glasses.

3: This is the biggie for me. It's not refined yet and it's a pure piece of innovation that I can see a lot of people hopping onto using this. Real 3D for the iPhone 4 and iPad WITHOUT 3D GLASSES.

This is made possible on the Nintendo 3Ds as the screen is relatively small and being a handheld device you can pretty much guarantee that someone will be looking at the screen straight on and a certain distance away. This becomes more complex with 3D Tv as people could be sitting at various distances and angles to the screen. On the iPhone 4 and the iPad Jeremie Francone and Laurence Nigay of the EHCI Research Group have thought outside the box and used the front facing camera to track where the viewer is and change the graphics to suit.
