Eye tracking in Smart Phones

The new Samsung Galaxy S IV looks to be the first smart phone to be release which will  have in-built eye tracking. This will provide additional functionality to the user in being able to “Eye Scroll” as a form of navigation. However, it is also raising privacy concerns as reported by Future Tense.  With eye tracking becoming more main stream this could possibly open up new research opportunities in running eye tracking experiments and analysing Big Data.
