What you need to know
- Apple has been granted a patent relating to eye tracking.
- The tracking unit would likely be head-mounted.
- The patent was originally filed back in 2016.
Apple has been snapping up eye tracking patents all year and its third has now been granted. Just like the others, this one comes from the company's acquisiton of SMI SensoMotoric Instrumments in Germany. And it relates to a fancy head-mounted display system.
As the folks at Patently Apple note, a new patent titled "Eye tracking device and method for operating an eye tracking device" has been granted. This one relates to an eye tracking device that includes an optical system which is capable of capturing at least part of an eye.
There are multiple potential implementations for such tracking, but they all need to be attached to someone's head in order to work. That could be glasses, a headset, or something else altogether.
We'd strongly suggest checking the Patently Apple piece out because it has way more detail than we're going to get into here. This isn't a particularly new patent either – it was originally filed back in Q4 of 2016 and carries patent number 10,437,327.
It's also very important to remember that not all patents turn into shipping products, especially in the world of Apple. The company applies for patents each and every time one of its engineers invents something worth patenting. Even if it is never likely to appear in a product in Apple's lineup.
