… The patent details a method of using a device’s accelerometer, GPS, compass, and gyrometer to establish a precise point in space for the device. It would then locate the user’s eyes (presumably with the front-facing camera) and combine all of this data to create a precise presentation of 3D content.
The patent continues to display how Apple could use layers of UI elements to contribute to the 3D effect. You may not have noticed, but icons on iOS devices’ homescreens have subtle drop shadows. One simple example of this tech would be to adjust (in real time) the position of the drop shadow in relation to the icon. Voila: instant 3D.
One of the coolest parts of Apple’s patent is that the 3D would be activated with a 3D gesture. …
