Face ID suddenly stopped recognizing me... Now that I think about it...

The gym, which I started going to at the end of the year, offers an early morning course from 5:00 to 10:00 at a very low price of 3,000 yen (excluding tax) per month, but there is no staff during this time to cut costs. is operated by This is supported by an entry/exit system that uses facial recognition. When the face is recognized in front of the door, the name is displayed and unlocked, and the operation is smooth and has never failed. Changes in weight On the other hand, Face ID, the iPhone's facial recognition system, has been failing to recognize more and more. The other day, while taking a walk in the morning, I opened my iPhone to charge Suica, but face authentication failed. The Suica app checks Face ID when it starts up, but if it fails here, you'll be asked for your passcode. I tried changing the angle of my face and changing the lighting conditions, but no matter how many times I tried, it didn't work. Come to think of it, Face ID has been failing more often lately. There were many cases where it was recognized when the vertical angle was changed, so I canceled it once and tried again and it passed. That kind of thing happened occasionally, but it was the first time I didn't recognize it to this extent. Apple's support page describes how to deal with such cases.・If Face ID does not work on an iPhone or iPad Pro　I have checked for updates, Face ID settings, and the presence of a mask to see if there is anything blocking the TrueDepth camera, but there is no particular problem. "If your appearance changes dramatically, you can still set it as another appearance so that it can be recognized by Face ID," so I decided to follow this.

Another Appearance

Since it's called "Another Appearance", you can only add one appearance. You can't register any more, so if this doesn't work, you'll have to reset Face ID. When I registered again, the recognition rate improved dramatically, and since then I have not made any mistakes. There is a reason why I stopped recognizing it.　Since I first used Face ID with the iPhone X, it was in the fall of 2017. Four and a half years have passed since then. "For many users, Face ID will continue to learn as the person changes," he said, but it seems that there have been changes that cannot be handled. Since I lost 15kg in half a year due to road biking (including Zwift indoor riding), which resumed in April 2021, my appearance has changed considerably, and more and more friends have pointed out that I have lost weight. Family members who hadn't seen him for a while worried that he might be ill.・Is GW prohibited from traveling? "Is the gym closed?" Okay, then Zwift.Speaking of which, it seems that the recognition rate of Face ID has been declining since the winter of 2021 when my weight stabilized. Face ID measures a 3D map of the face with TrueDepth's depth sensor and compares it with registered ones to identify it. It is said that "continuous learning accompanies the change of the person", but it seems that it was not in time. Does it mean that he succeeded in dieting to outsmart Face ID? However, since I scan my face many times every day, I would like to use it more effectively. "You've lost a lot of weight," "You should change your diet," "Your eyes are red, but are you getting enough sleep?" I would like to see a "mirror" feature added someday.　The built-in camera periodically scans the face to estimate the health status, and if there is a problem, the emergency contact can be notified.・My grandmother, who quickly mastered the iPhone, and my grandfather, who needed an AirTag.The year-end and New Year holidays when I reviewed the IT environment at my parents' home.The other day, a medical student in the audience who saw the NHL team staff's neck said that the staff's mole was cancer. It was reported in the news that it saved the life of a staff member by informing them that it might be showing signs, but there is a possibility that the same kind of thing can be done by the face recognition system that we use every day. "Mulder, you're tired. And the shape of that mole might be skin cancer. I'll make an appointment with you."・ What is “really smart” from the perspective of smart speakers?
