Samsung Galaxy S IV will track users’ eyes to scroll pages. Basically, according to the report, once your eyes reach the bottom of the page the phone will use the front camera to detect it and then automatically scroll down to the next few paragraphs.

Now Samsung mobile has confirmed that the Galaxy S IV will have the Smart scroll feature, along with ‘Smart Stay’, ‘Smart Pause’ and ‘Smart Rotation’ features.

According to the Israeli blog, the Smart pause feature will apparently pause a video if the phone detects that the user is no longer looking at the screen, while the Smart rotation feature ensures that the screen rotates only if the phone is held at an angle.

If e like make I control the phone with my nose, ear & leg at the same time...I'm still not interested. All these Manufacturers have a way of ripping someone of his/her hard earn money especially the "wanna be's"

Mobile phones that fold, razor thin handsets powered by flexible batteries or see-through solar panels built directly into a colourful screen. These visions of our mobile future may seem a world away from our rigid, fragile and power-hungry smartphones today.

But they could all soon become reality thanks to the “wonder material” known as graphene. Believe the hype and these single-atom-thick sheets of carbon could soon replace just about every material and component used in modern day smartphones, making it lighter, faster and with more bells and whistles than ever before.

If these claims seem extraordinary, then so too is the material which could make them possible. Graphene is made of a single element, carbon, arranged in a flat, unchanging crystal pattern that looks like chicken wire. Although it may sound rare and complex it is simply very thin layers of graphite – the same as found in a common pencil. In fact it’s now realised that almost every stroke of a pencil leaves fragments of graphene in the shining grey trace on the paper

Samsung and Nokia [SF: avoiding repetition of a few paras above] have already shown off concepts for “bendy” phones – such as the newly unveiled Samsung “YOUM” screen or the Nokia morph concept -with shapes unlike anything seen today. Although less extreme versions of some of these concepts may first be brought to market using more conventional technology, Nokia researchers believe that “graphene may well be one of the crucial elements of making Morph reality”.

Although these kinds of concepts excite the imagination and show the possibilities of graphene, durability is where the greatest interest lies. What the industry really wants is a touch screen a user can stab thousands of times a day without fear of the electronics ever giving out. Again, that’s what makes graphene so attractive.

Of course it has to be cost effective, too. As recently as 2009, it was only possible to manufacture samples of graphene that were a few centimetres across. But in 2010, Samsung-backed researchers at Sungkyunkwan University in South Korea showed it was possible to create roll of metres of the material, and demonstrated it on touch-sensitive tablet screens. And since then Sony has built a machine that can create rolls of the material 100m long – claimed to be the largest sheets in the world.
