A future iPhone could be controlled without you even touching it. Apple is exploring touchless gesture control and curved screens, according to the latest rumors from Bloomberg. A display that "gradually" curves inward from top to bottom is still at least two to three years away, while the touch-free tech "likely won't be ready for consumers for at least two years." That's assuming Apple finds merit in continuing with the R&D cycle for it.
Apple’s closest rival, Samsung, has already offered versions of both technologies in its prior models. Air Gestures on the Galaxy S4 allowed users to browse between photos or scroll a webpage just by swiping in the air above the phone, while Air View would function much like Apple’s 3D Touch, exposing additional information when you hover your finger over a trigger area. Flagship Samsung Galaxy S phones have had curved screen sides for years now, though the Bloomberg report indicates Apple’s curved iPhone display would “curve inward gradually from top to bottom.”
Gesture controls are another thing altogether. While Face ID makes it easy to unlock a phone without touching the screen more than once, many of us are already familiar with the swipes and taps a touchscreen enables. Accurate gesture control has always been a bit fiddly unless you have a serious amount of movement tracking tech as seen with the HTC Vive or Microsoft's HoloLens.
Of course, Apple works on far out technology all the time, and more often than not, it doesn't come to market. Remember when the company teased swappable camera lenses back in 2013? Or a solar powered iPhone? Well, it's six and eight years, respectively, since those patents were filed and neither feature has been added yet.
