This is probably one of the weirder rumours about the Samsung Galaxy S3 - which at this rate could be renamed Galaxy-everything-but-the-kitchen-sink.
Cnet's Andrew Hoyle says that the Galaxy S3 will come with eye-tracking technology as part of Samsung's push to include more "human interaction" features.
Some rumours have mentioned that the smartphone's front facing camera will have a three-megapixel resolution which is very likely if it needs to pick up whether or not the user is looking at the screen and when.
Doyle mentions the example of text entry. Looking away for example would lock the screen (ed : but what happens when you try to touch type without looking at the screen then?).
The Galaxy S3 will be launched on the 3rd of May in London and will almost certainly be hailed by Samsung at the official smartphone for the London 2012 Olympic games.
Amongst the various purported rumours about the Galaxy S3; here's our pick. It will have a quad core processor (possibly the Exynos 4420), either a 4.8-inch full HD display or a 4.65-inch HD ready one (like the Galaxy Nexus), a ceramic case (or aluminium), NFC, wireless charging and an eight megapixel rear camera.
