Believe it or not, such feature already exist in the Accessibility section of the Settings app in the latest beta of Apple’s new OS is a toggle that activates a new head tracking feature. Once enabled, users can control their iOS devices with simple left to right head nods…
The way it works is that a blue box will slowly bounce around to different buttons, toggles and other UI elements on your screen. When it lands on the object, or group of objects you’re interested in, a quick nod of your head will initiate an onscreen tap.
It doesn’t look like Apple has anything planned for the feature outside of accessibility, so don’t expect to see Galaxy S 4-type gesture actions. But nevertheless, it’s cool to see Apple finally start tinkering with all of those sensors it stashes in its iOS devices.
