It doesn’t take much to smudge up your smartphone’s display. However, a patent from Apple hints that this may not be a problem for future iPhone users. Titled, “Intuitive, Gesture-Based Communications With Physics Metaphors,” the filing describes a function that lets you make a physical gesture that will be picked up by onboard motion sensors. Additionally, the patent describes ways in which the front-facing camera could analyze your moves to execute tasks. These innovations sound similar to those offered by the Samsung Galaxy S4, whose Air Gestures will allow users to scroll through photos, advance music tracks and more.
