Apple has won a patent for a plethora of future sensors that could reside anywhere underneath a display for Face or Touch ID, Gaze & Gesture Tracking+
Apple has been granted a patent for what seems to be, in-part, related to the iPhone 14s Dynamic Island. Apples patent states that the notch area in the display will have areas in the display with transparent windows that may have different shapes and sizes." A notch thats able to present different shapes and sizes translates to being the Dynamic Island. Yet the patent goes far beyond this single feature.
