On January 19, the qicha website showed that Apple published a patent for "detecting falls using mobile devices". After Apple Watch detects a user falling, if it does not stand up or cancel the warning message in time, Apple Watch will send a fall message, the user's location to the emergency contact, and so on.
The patent abstract shows that after the user falls at the first time, if he does not move in the second time and the third time, the Apple Watch will request an emergency response communication at the fourth time. If the user does not cancel the emergency communication request, a distress message is sent.
The second and third time "movement" here includes not only the positional movement as conventionally understood, but also the hand movement. Many people have broken their feet after falling and cannot move, and some people will fall on the side of the road when they are drunk and lose consciousness.
Apple Watch detects a user's fall behavior through components such as gyroscopes and accelerometers. At the beginning of the release of this function, Apple spent several years collecting real fall data for more than 2500 people, and Apple's research and development team made these mathematical models, and finally formed a more mature fall detection function.
Since the release of this function, it has played a lot of roles, and the recognition degree is relatively accurate. After many people use it last time, it is difficult to leave this function. It is similar to buying a life insurance, but also for personal health protection, many users are willing to pay a higher premium for such features.
The experience of domestic smart watches is not particularly perfect, in the future, with the aging of the mainland, there will be more and more users paying attention to the health functions on smart watches, Xiao Lei suggested that domestic smart wearable device manufacturers can develop in this regard.
When Xiao Lei bought the Apple Watch Series 7, he considered that its service life was actually very long. After using it for a few years, you can use it for children and the elderly. For children, it can help monitor the child's position when going to and from school. For the elderly, Apple Watch Series 7 has fall detection, ECG and other functions. With a usage period of about 8 years, the annual cost of using the Apple Watch is not too expensive.
