Eye-tracking Samsung Galaxy S4 unveiled
Samsung has launched a smartphone which allows users to control its 5in (12.5cm) screen using only their eyes.
The Galaxy S4 follows on from last year's S3, a product that sold over 40 million units worldwide.
The device was unveiled at a lavish, Broadway-themed event in New York.
Technology analyst Carolina Milanesi, from Gartner, said the key to its success would be whether its novel features would be of use on a daily basis.
Michelle Fleury reports from New York.
