The Patent and Trademark Office granted US patent rights to Apple for a system of 3D gestures in the air. A series of 55 different applications, is patent in question is titled as "Three-Dimensional user interface session control" and It was published in May 2015.
A year later, Apple filed a patent application below entitled "Three dimensional user interface using depth sensors monitoring session." With so many patent applications and patents granted in this invention in a short period of time, it is clear that this type of technology is one of the things that Apple could be adapted for future Macs together with your iSight dual lens camera that will possibly include in the next generation smartphone.
The image above shows illustrations of 3D user interface in different actions that respond to vertical movement of the user's hand (6A, 6B, 6C, and 6D).
Apple has also filed a second patent continuation of this invention, in September 2015 that differs from the current two patents granted. In that patent, once again the changes are reduced to adjust aspects of the original concept.
This type of patent would clearly apply to Apple TV, replacing all or part of the conventional remote control functions including the device. That's not all as it could also be applicable to future Macs to perform tasks using gestures made at a distance, without direct contact with the device.
