Yesterday the US Patent Office issued a new Apple permit for eye tracking on electronic devices. The patent is mainly focused on electronic devices they wander user.
Simplified tracking: 3D and image recognition
At a general level, eye-tracking systems are divided into two types: those that are silent on the user and those that respect the user. The first type of solutions will work with less realistic physical mirrors when the area in our head is fixed. These programs are, in general, effective two infrared sensors with active light
With the technology provided by Apple, it's possible to find where we want to use the 3D integration system and the optical detection system that requires a single light source. Through this system the eyes are obtained using a 3D sensor and the RGB sensor obtains the optical direction. The 3D detail allows determining the shape of the head and the lower RGB obtaining the optical direction of the relation between the position of the head and staring, providing a broader context. Thanks to this technology, eye tracking can be done successfully even when the device is close to us.
As Apple points out in the same patent, with this program you can, for example, tell Mac to move content on the screen, for example it goes down to a web page where it detects that we are facing down the screen. On the other hand, when we think of a device where the images it shows must be in line with our eye movement, without the Mac's optical control technology, an important product comes to mind: future apple glasses
Even though developing an eye-tracking system to increase access to Mac computers, allowing us to interact with our iPhone or iPad smoothly without having to touch too much on the screen or seed of Apple's upcoming glasses, it's clear that the company continues to develop good news.
