Samsung Galaxy S3 to get eye-scrolling feature with Android update?

The eye-scroll feature expected to be front and centre in the Samsung Galaxy S4 could be on its way to the tech giant?s current flagship too, revelations from one of the tech world?s more straight-talking analysts suggest.

In recent weeks, rumours have been mounting that the Galaxy S4 will team the handset?s front-facing camera with new software to enable owners to scroll through pages using their eye movements alone.

The feature is expected to feature heavily in S4 marketing materials, as Samsung bids to differentiate its handset from the Android competition, as well as earlier Galaxy kits.

However, it?s unlikely to remain exclusive to the Galaxy S4 forever.

According to a tweet from mobile-industry expert and editor of Mobile Review Eldar Murtazin, early versions of the Galaxy S3 firmware had eye-scrolling on board, before it was scrapped for reasons he doesn?t elucidate.

But, given that the S3 already supports limited eye motion controls in the form of the SmartStay intelligent sleep mode, we think the omission was probably mostly to do with the software?s scrolling functionality not being ready rather than because the phone cannot support the feature.

In turn, this makes it likely that Samsung could bring it to the phone in future via an Android update in much the same way that it added functions such as Multi-View and Page Buddy, that had been exclusive to the Galaxy Note across to the Galaxy S3.

The move would certainly breathe new life into the S3 when it becomes Samsung?s de facto mid-range model and is superseded by the newer handset as the company?s top-end option.

News of Samsung?s plans for eye motion controls come after separate reports yesterday citing a source who claimed to have used the Galaxy S4. According to the Samsung insider, the handset will ?track a user?s eyes to determine where to scroll?.
