Samsung Galaxy S4 with eye control to be launched at New York’s Radio City Music Hall on March 13

Samsung Galaxy S4 will be unveiled in New York on Wednesday and rumors are the device will feature eye control.

Galaxy S4’s predecessor, the S3, already had a feature called Smart Stay that detected if users were looking at the screen.

But Galaxy S4 is expected to have revolutionary functions such as “eye pause” and “eye scroll”, which will let users scroll around apps and websites simply by moving their eyes.

Since its launch last year, Galaxy S3 briefly outsold the iPhone 4S but after the release of the iPhone 5, Apple have regained the top spot.

However, Galaxy S4 is predicted to become the biggest seller when it hits the stores in a few weeks thanks to rumored technological improvements such as wireless charging.

It is also expected to be powered by an eight core processing chip, compared to the iPhone’s two, and to have a larger screen – 5in compared to 4.8in on the S3.

Other leaks suggest Galaxy S4 will have a 13 megapixel camera, as opposed to the iPhone’s eight.

Francisco Jeronimo, from technology analysis firm IDC, said: “Apple is not the one leading the market. I wouldn’t be surprised if the new Samsung device sells more than the new Apple device over the next two years.”

Galxy S4’s launch ceremony will be held at the famous Radio City Music Hall and will be broadcast live in Times Square.

South Korean electronics giant Samsung have released a few teaser advertisements for the phone, which show a boy’s face being lit up by a golden glow as he opens a box containing the S4, with the catchline “one of the most amazing products to hit the market since TVs went color”.
