Apple might be building some bold new features for future generations of iPhones: touchless gesture controls and curved screens.

According to Bloomberg, the new technology wouldn't arrive for another two years at least, and Apple has yet to determine whether or not it'll move forward with the ideas.

The differences between smartphones are becoming more and more minute, so the innovations could help Apple further separate its device from the pack. Still, other companies have implemented similar features in the past. A few years ago, Samsung rolled out a concept for its phones called Air Gestures for touchless gesture control, and has already had favorable outcomes from utilizing curved screens.

Bloomberg reported that Apple is still figuring out how iPhone users can control some tasks by moving a finger near the screen. If they do implement curved screens, then they would curve “inward gradually from top to bottom,” and not on the sides like Samsung phones.

For the forthcoming iPhone generation, Apple is reportedly releasing three sizes, with the largest to top the iPhone 8 Plus’ 5.5-inch screen, with about a 6.5-inch screen.

The new iPhone is expected to be unveiled in September.
