3D isn't a new concept - in fact it has been around since the 50s and had a re-emergence in the 80s and again 00s.

People flocked to the theatre, donned a pair of snazzy blue and red specs and felt part of the action (well more than they had previously!) The glasses may have changed and the technology evolved into TV but to experience 3D one needs the extra piece of kit, in the form of glasses, to make your brain think it is seeing another dimension. 

In 2004 Sharp revolutionised the way in which people could interact with 3D and produced the Sharp Actius RD3D notebook, which didn't require glasses.  Although the notebook has since been discontinued other brands have run with the idea. Hitachi released a 3D phone in 2009 and in the same year Fuji brought out a 3D digital camera. 

Now there are a number of 3D phones on the market but Sony Ericsson have used the 3D technology one step further - by offering 3D images to 2D phones.

The new Xperia Arc S from Sony Ericsson will be able to take 3D panoramic images using a standard camera, with the feature expected to be added to other devices in the Xperia line. However, the third dimension to the images will not be visible on the handset itself, but will appear in simulated 3D when connected to a TV with the appropriate capabilities.

Although it is unlikely that those who have a 2D phone will have a 3D TV, it does show that manufacturers are defiant that technology will move more into 3D and cost of products (such as the 3D TV) is likely to go down. 

Scientists are still looking in to 3D and its effects on the brain, but those studies will probably be ready when the world has access to the new technology on a daily basis - let's just hope we aren't damaging ourselves just to see that extra dimension.
