Apple is expected to use a system of three-dimensional facial recognition in iPhone 8 and this is making to strengthen the security of the phone.
Technology analyst Rod Hall said the American giant will use the new 3D system, which is expected to replace the scanner for fingerprint recognition, whereas previously it was reported that the device may have an iris scanner.
The new 3D scanner will add another 10 or $ 15 bill for the creation of iPhone 8. The module is expected to be used VR technology already used enough.
This would pave the way Apple to improve in terms of games. For this option Apple may have an extra accessories AR / VR.
Apple's new phones are expected to launch in September.
Basics of the technology
A 3D sensor needs a few key features —it needs a light emitter in the form of a LED or laser diode, a light filter for a noise-free scan, and a speedy image sensor coupled with a powerful signal processor. Each aspect has some implementation difficulties, which Hall believes have been rectified by Apple and partner Primesense in a relatively inexpensive package that should add not much more than 3 percent to the build cost of an iPhone.
At first glance, the technology described resembles a miniaturized version of a LIDAR mapper or rangefinder.
At present, at macro scale, LIDAR is used in many physical sciences, and heavily used by the military in ordnance guidance suites. Resolution and accuracy greatly depends on a combination of factors, not the least of which is the integration of the laser and the sensor —which Apple's acquisition of Primesense appears intended for.
Miniaturized hardware
Any 3D laser scanning apparatus in a smartphone would likely be introduced in a wafer-level "stacked" optical column, rather than a conventional barrel lens.
While more complex, the stack occupies less volume in the phone, and is arguably more resistant to damage. However, optical diffraction can be a problem, as can lower yield rates in production, potentially driving the cost up, or being a supply-limiting factor in getting devices equipped with the stack to retail.
The technology has more use than facial recognition. A potential API release, which is probably not likely early in the hardware's life, could open up other uses like ultimate use in augmented reality and virtual reality headsets, clothing sizing, accurate distance measurements for home improvement, scanning for 3D printing, appliance and HomeKit integration, and other applications needing precise volumetric scans, or range-finding needs.
Outside Cupertino
Given's Apple's ownership of Primesense intellectual property, the company stands to gain from other industries implementation of the technology as well.
"Creating small, inexpensive, 3D scanning modules has interesting application far beyond smartphones. Eventually we believe these sensors are likely to appear on auto-driving platforms as well as in many other use cases," writes Hall. "Maybe a fridge that can tell what types of food you have stored in it isn't as far off as you thought."
While the "iPhone 8" is expected to be laden with all of Apple's newest technologies —including an OLED wrap-around display, fingerprint sensor embedded in the screen glass, and others —the 3D sensing technology may not be limited to just the high end. Hall believes that there is "more unit volume" for production of the sensor sandwich, opening up the possibilities that it will appear on the "iPhone 7s" series, in addition to the expected $1,000+ high-end "iPhone 8."
Apple purchased Israeli-based PrimeSense in lat 2013, for around $360 million. PrimeSense created sensors, specialized silicon and middle-ware for motion sensing and 3D scanning applications, and was heavily involved in the development of Microsoft's Kinect sensor technology before the deal.
