Samsung Galaxy S4 may feature eye tracking technology

Is Samsung going to spoil RIM's big BlackBerry 10 party without so much as lifting a finger?

That looks like a distinct possibility, after a spectacular new rumour regarding the Korean firm's forthcoming Galaxy S4 handset broke cover.

The latest speculation has the next-gen Samsung smartphone featuring eye tracking technology, after a dedicated Galaxy S4 gossip site revealed that the electronics giant had filed to trademark (see image, bottom) a pair of interesting features, dubbed Eye Pause and Eye Scroll, only last week.

Details regarding the potential game-changers are still thin on the ground, and if we're being honest we think it all sounds a bit optimistic for 2013. That said, it's a sensational possibility even if it does nod to the future somewhat.

The sketchy chitchat points to Eye Pause detecting when a user diverts their gaze from a smartphone or tablet screen, so if you were watching a film but suddenly got distracted, playback would halt. Eye Scroll would be an even more nuanced feature, tracking retinal movements across the display and furnishing fresh content as appropriate.

Even if these futuristic showpieces don't arrive in 2013, the Samsung Galaxy S4 is still lined up to have plenty going for it: an 8-core Exynos 5 Octa processor and 4.99in Full HD display are among the hottest tips to date.
