With the push of the iOS 15.4 update, I believe that many small partners who use Apple's iPhone have begun to notice a magical function, that is, Apple supports wearing masks and can also support face unlocking. In the past, in order to solve the problem of safety and convenience, many small partners bought the Apple Watch by hand, and now you can get the evaluation of the king here to change the stainless steel basin (mistaken). In fact, there may be many small partners who are more concerned about a problem, that is, can domestic mobile phones follow up? The ideal is wonderful, but it seems a little difficult now.
Technically, Apple's FaceID is indeed a bit special, it projects invisible light on the face through a dot matrix projector, and generates a graphic through the projected light, and the Apple phone can recognize facial information through these graphics. In terms of security, this method itself has left enough redundancy for some special cases, even if a part of the facial information is sacrificed for recognition, the impact on security is not large. In particular, Apple uses the area around the eyes as a key recognition area, and wearing a mask exposes exactly the eye area.
But such technology will also have a certain price, that is, it must reserve enough space for this set of modules, including dot matrix projectors, infrared lenses, etc., and there must be bangs or large foreheads on the mobile phone. This is also the fundamental reason why Apple's phones have never changed their appearance from the iPhone X all the way to the latest iPhone 13. Not only Apple, but also the development of electronic products, you will find that most of them are like this, and the powerful functions, performance and good-looking appearance are incompatible.
On the other hand, the Android market, especially the domestic Android mobile phone, has now become more and more inclined to a concise design, in order to ensure that the cost and aesthetic have enough competitiveness, the mobile phone can only dig holes, and the holes should be minimized as much as possible, and even small enough to dig the hole screen as a selling point. In this case, similar technology is not allowed at all, whether it is structured light recognition or TOF recognition, which cannot be accommodated on mobile phones. So what about facial recognition with a mask through a camera? Don't be funny, even if you don't wear a mask, there will occasionally be a recognition error, and wearing a mask can only be guaranteed by safety.
Through this point, it can be seen that there are similar devices and theoretically can achieve the same function of mobile phones are already rare, and are old products, such as Huawei Mate40 Pro or the older Huawei Mate30 Pro, will manufacturers add such features for old products? Where there is no technical selling point that can stimulate sales, do not have extravagant expectations for manufacturers. New mobile phones in 2021 and 2022 are completely unlikely to open a large opening on the screen and then carry similar hardware solutions, and the corresponding functions will not be able to talk about.
Therefore, wearing a mask face unlock this technology, may only appear on Apple mobile phones, not how unique the technology is, but the development of Android mobile phones all the way down, the development trajectory has been doomed to abandon this type of technology. Honestly unlocking with fingerprints is also a good choice.
