The password is a guarantee for wealth. And we are adding this guarantee to every channel that can involve wealth. From the key of the safe to the secret of the bank card, from the command board of the virtual account, to the COMS lock of the PC. However, from the first year of smart people, people’s dependence on smart phones has become higher and higher, and the necessity of going out has also changed from 'key to money' to 'one hand'. It’s even more important to unlock it easily. .
At present, the most widely used mobile phone unlocking method is fingerprint recognition and unlocking. From sliding to pressing, fingerprint recognition technology has always been the easiest way to open a smart phone. In each era in the past, fingerprint recognition was in a different position, acting as Different roles. Below, we may wish to take a look back to see how the fingerprint unlocking that has become our subconscious operation is integrated into our mobile phone step by step and into our lives.
'Fingerprints from scratch, mobile computers step up to each other'
We first put aside the fingerprint mobile phones in the black-and-white screen era – such as a SIT/SVT from Siemens
The correct time should be back to 10 years ago, and back in a world where Saipan S60 system was almost uncontested. At that time, the core content of the mobile phone was to send text messages by phone and part-time to play a java-based game. The mobile phone of the era did not have a password or a password. The way most people unlock a mobile phone is 'left soft key +*'. Of course, the same is true for locking.
But with all exceptions, this first fingerprint recognition appeared in the world beyond Tokgo’s failure. Intel, which had not sold toothpaste in those years, launched the UMPC (the original ancestor of the current Ultrabook). "Ultra Mobile Personal Computer" is intended to be a concept of the "smallest PC". It is regrettable that this road did not go through that year, but the step taken that year was exactly the same as the step taken by the mobile phone industry. On one footprint, starting from this step, the performance of the mobile phone is getting stronger, and the notebook is getting thinner and lighter.
The practitioner of this concept is the parent company of Dopod, Taiwan HTC HTC, and this product is positioned as a “communication device with strong mobile office capabilities”. The name of this product is Shift, which is a dual system ( Vista+SnapVUE' can be understood as a lizard's castration WM6') dual processor (Intel 800MHz + Qualcomm 400MHz, corresponding to the above dual system) product, and this phone + computer product can be said to have become the first to have a fingerprint The recognition function of the phone, although his fingerprint recognition is derived from the logic of the computer unlocked from the ThinkPad notebook.
What's the drawback of this logic is that starting this 7-inch screen monster, each time the logic of full boot is like this - boot → enter Windows Vista → fingerprint recognition into the system → start the SnapVUE system, if we say in the fingerprint unlocked Historically, every improvement is a breakthrough pursuit of the operational experience. Each time it finds limitations and becomes better and better. That’s good, it’s good from nothing. From a current point of view, this is a very good taste, but the process of starting from 0 to 1 constitutes today's '0,1).
'Compared with sliding, this style of touch may be more reliable'
In the following years, the Android war started with the HTC G1 Dream gradually kicked off, and the behind-the-scenes promoter Google also successively out of their own son-level benchmark - numerous Nexus. From the keyboard to the touch-screen era, 1. A shuffle that cuts the leeks started.
In terms of systems and OS, Saipan started to touch screens from S60v5 and eventually disappeared; Fat (Palm) and Lizards (WinCE) fell to the ground together with their old friends; the guy renamed iOS began to harvest the app. The bonuses of the store; The BBer's love began to cling to the city; And from a "mobile" movie known to begin on Motorola's 388/388c and stormy open source system - linux, is like Mei Changsu In the name of Android, he began to sweep the entire mobile phone market. (Of course, he now has two subsystems, one is called Android and the other is Android. I believe those who don't have Google Space apk and don't even use Steam Security can't use it. , I must know what I am looking for:)
In terms of product branding, we have seen the rapid rise of the ham from G1 Dream to G7 Desire; seeing another way to go from Bada to Tizen, but always Galaxy's three sang; saw the repeated launch of the 'iPhone killer' but failed repeatedly in the resistance On the screen, from the joint Intel Meego to the Mango's Emperor Saipan carrying MS, with the first phase of smoke evacuation, the way the capacitive screen was unlocked by the mobile phone began to truly turn upside down... However, on Android In a few years, his unlocking interface was like this...
Say this kind of interface is simple, the person who draws the picture is tired finally is cruel enough, from time to time also often is like the daily routine of the chicken to select the hand to lock the dead screen; Say this kind of interface is complicated, it is a standard anti-gentleman does not prevent small People have to design, people who want to break have hardly cracked...
When such barriers emerge, it actually means that this kind of tossing people's unlocking methods urgently needs an improvement, and they urgently need a breakthrough in the operating experience. This time, breaking this barrier is the oldest qualification in the mobile phone industry. The company, which entered the industry in 1972, is known for playing carbon fiber and playing blades. Its name is Motorola's way of breaking down and it is called sliding fingerprint recognition.
In the age of frozen yogurt system, there is still no current virtual button on the front interface of Android phone, so there are fixed buttons at the bottom of the screen. In order not to make the chin of the phone look so sizable, Motorola engineers will place this identification area. At the top of the back of the fuselage, users can use this fingerprint identification device to rapidly bypass the tedious nine-point connection to unlock and quickly enter the system. If we say that in the history of fingerprint unlocking, every improvement is A breakthrough pursuit of the operational experience, each time discovering limitations and getting better and better, is a good step across the platform and finally has the ability to rely on fingerprints in a real sense. Mobile phone.
'Location dispute, which pose is the most depressing'
In the following years, various brands began to look at the world, and with the emergence of the “Five Kid Security” flag, the era of “no fingerprints are too embarrassing to say hello” was initiated. In this era In addition, fingerprint recognition was mainly controlled in three areas with each other's complement and R&D read by each person, namely the front chin, the side power button and the upper and middle area of the back of the camera.
Fingerprint recognition during this period has given up sliding-type unlocking and switched to push-type unlocking. From a technical point of view, the biggest difference between the two lies in the algorithm: Sliding is to collect multiple frames to form a complete fingerprint and then capture. Feature points, and the press type is to directly select the fingerprint of the area to collect feature points. From the user experience, real-time fingerprint image processing and reliability: Press type is better than sliding type. Press type just gently place the finger , The speed and force of the finger movement during the sliding process will affect the image acquisition. In addition, with the integration of the HOME button, the press type is more natural. Press (place) a finger, sensor will collect multiple images, and slide once, the image Only once collected, the theoretical recognition rate will be higher.
On the front chin: The most intuitive and convenient, but the position of the chin
For fingerprint recognition, the front is the most intuitive, and the most used thumb army has chosen this method as an application, but similarly, the drawbacks of this method have gradually become prominent in recent years. The first is that fingerprint recognition is often used. Need to sit on the phone's 'chin', if it goes back to before the virtual key era, then the phone will have the key + fingerprint's double chin'; If you want to install a positive two-speaker, then the 'three chin' is also not surprising With each increase in the number of chins, the proportion of screens on the front of a mobile phone is absolutely impossible.
In terms of stability, this most intuitive unlocking method also makes people sweat. In the mobile phone screen, the screen is larger and larger, but the size of the user's hand is fixed. Even though the screen has reached 5.5 inches, the screen has started a new growth of 'Seeing height but not wide'. In other words, it is the mobile phone is getting longer and longer. A longer screen can show more content, but at the same time when using the thumb When unlocking the fingerprint reader underneath the front screen, it enters a routine test that tests grip strength and thumb flexibility.
On the side of the boot button: boot fingerprint 2in1, but the left-handed user said! @#¥%......
Lateral fingerprint recognition, in fact, is a kind of adjustment after finding that the front is insufficient. I believe the original developer must be thinking that the phone's power button is on the side. If the fingerprint recognition is on the side, it must be very easy to operate. The idea is very good, but the reality is a real sense of the bone. Not to mention that some fingerprint identification keys and power points have not been done together, giving the user enough logical challenges; just say that the fingerprint boot combo The product, this type of product in the user's view, ignores one of the most basic flaws - the phone is getting thinner and thinner, but fingerprint identification is not, but the width of the widest side of the fingerprint recognition can only be 8mm When you use it, you can use almost only one thumb (right hand) or index finger (left hand) to perform the unlock operation. For the right hand, you can only say that it is okay to use the thumb. The possible error is based on the X-axis offset of the force point in the thumb. For the left-handed person, when the unlocking is based on the Y-axis displacement of the force point of the index finger/middle finger, multiple unrecognized situations may occur directly.
The upper part of the back of the fuselage: more humane solution, but will be subject to the operation
Compared with the large-screen positive 'scratching' and the ultra-thin side's 'unsettling', no surprise in the back window is a more balanced solution. It can make the screen bigger than possible. Under the premise, the screen can be made as large as possible. At the same time, because it is recognized on the back side, most people will unconsciously use the index finger to open, and the fingerprint area of the index finger is greatly reduced compared with the area of the thumb, and the accuracy can be achieved as much as possible.
However, similarly, there are some 'minor shortcomings' in fingerprint recognition on the back. For example, mobile phones cannot be directly unlocked when placed on a table or in a bed. For example, in a time when a large number of glass/fibre bodies are used, the strength caused by the opening in the middle of the back is reduced. It seems that unlocking the back is a good compromise, but it is far from the best solution.
This period of development can be said to be a typical example of "From Three to Ten Thousand" written by Deng Tuo. This is a breakthrough pursuit of breadth of fingerprint recognition. Everyone can use a fingerprint-based mobile phone. In the case of the mature Tick-Tock approach, the next change should be further in depth.
'Hidden on the back, faint at the screen'
In June 2017, Vivo demonstrated screen fingerprinting technology.
In September 2017, iPhone's new phone was cancelled fingerprint recognition and turned into facial recognition.
In January 2018, Vivo introduced its first screen fingerprint recognition mobile phone X20Plus UD screen fingerprint version.
In March 2018, vivo X21 launched the market after optimizing screen fingerprinting again.
These two messages can explain the hidden dangers of a mobile phone's fingerprint recognition. When the popularity of mobile phone fingerprint recognition meets the beauty of a full screen, then either compromise on one of them, or leave the other on the basis of keeping fingerprints and a full screen. A road, the two will be combined into one, so the new fingerprint unlocking form - the fingerprint under the screen came.
Screen unlocking is based on screen fingerprint sensor using photoelectric fingerprint recognition technology. The recognition principle is to use blue-green light emitted from the pixels of the OLED display screen to illuminate the finger and illuminate the fingerprint lines. According to the principle that different lines reflect different light, the biometric information is captured. Then these light reflections carrying bio-information penetrate the screen and return to the fingerprint recognition chip. The fingerprint recognition chip forms a fingerprint image based on the reflected light, and compares the software processing and the algorithm to compare the recognition. When the screen fingerprint is unlocked, consumers are required to Fingers fit tightly on the glass for effective reflection.
Compared to the previous volume change, the emergence of fingerprint mobile phones represented by the vivo X21 can be said to further advance the qualitative change of fingerprint recognition. As I said before, if every improvement is an operational experience In a breakthrough pursuit, each time it discovers limitations and then becomes better and better. This change in the future will be an ultimate limit to the ultimate.
'Where will the next change be?'
If you start from Siemens Engineering Machine, then the road between mobile phone and fingerprint has been gone for no less than 20 years;
If you look at the Shift dual-system platform, the smart phone and the fingerprint have gone this way for a full 10 years;
If you count from Motorola Artix 4G, Android smartphone and fingerprint have been on this road for 7 years.
If you count from the vivo X20 Plus, then the story of Android smartphones and on-screen fingerprint recognition also began for nearly 2 years.
Thanks to these ancestors, they made their attempts to become the common sense of the entire market. Although people-oriented slogan can no longer hear the original broadcast, we can learn about the changes in mobile phones again and again. , Its convenience is getting closer and closer to me.
Where will the next fingerprint change begin?
The password is a guarantee for wealth. And we are adding this guarantee to every channel that can involve wealth. From the key of the safe to the secret of the bank card, from the command board of the virtual account, to the COMS lock of the PC.
