The presence of smartwatches is getting bigger and bigger and they are likely to become second portable device after mobile phones. Just as main function of a mobile phone is no longer just to make calls and send text messages, it would be too bad to buy a smartwatch just to show time. So, what to look for when buying a smart watch?
Smart watches seem to have more and more features, but there are basically two categories: sports features and health features. The sports function revolves around some common sports methods. The watch plays role of recording and reminding. Whether it is a bracelet or a watch, sports functions are basically same, and even sports sensors used in watches of different brands come from same supplier.
Health feature tests manufacturers' R&D capabilities and is place with highest technological gold content in smartwatches. If you are only considering sports, a smart bracelet under RMB 300 is best choice, but if you want more experience, you should consider health features.
Currently, health-related features of smartwatches include biochemical functions such as monitoring heart rate and detecting blood oxygen saturation, and detecting accidents such as falls and bumps. Although these features seem too conceptual, in real use they will really save lives at critical moments.
Heart rate monitoring
Earlier, Apple Watch was equipped with a heart rate monitoring function. Many users have been saved by wearing Apple Watch, and many media outlets have repeatedly reported on this. For example, in April 2018, while Oklahoma student Skylar Joslin was at school, his watch alerted him to an abnormal heart rhythm. Jocelyn had previously suffered from tachycardia, so he deliberately sent a reminder to his mother. After that, Jocelyn's mother immediately picked him up and took him to nearest emergency room. This visit took 7.5 hours before Jocelyn was able to turn corner.
Blood oxygen saturation detection
The determination of blood oxygen saturation has been delegated to many smart watches. This feature may not normally be used at normal times, but during just past national holiday, it really showed a sense of presence.
Many users who travel plateau report that in severe altitude sickness, watch shows blood oxygen saturation close to 80%, while normal range is between 95% and 100%. Many users basically adjust their oxygen inhalation schedule and rhythm according to watch reminder. In addition, pneumonia often plummets with blood oxygen saturation. The UK provides oximeters to people in all high-risk areas of infection, and smartwatches equipped with blood oxygen saturation features have become popular.
Fall detection
There are other examples of fall detection. When user falls, watch evaluates their status. If user cannot move, watch will automatically send an alarm and transmit location information.
This feature may provide potential protection for older users and users who enjoy cycling and other sports. There was a young couple in New Jersey who accidentally fell off a cliff. Due to fracture caused by fall, they were unable to move. They thought they would die without help. Suddenly, watch automatically dialed 911 to help them call. rescuers. On Chinese Internet, some users shared a similar experience: he fell while driving at night, and his mobile phone could not be used in place Apple Watch contacted "emergency contact" and was finally rescued. A user sent a thank-you note to Apple CEO Tim Cook and received a response.
It is understood that Apple is launching a "crash detection" feature for Apple Watch similar to "fall detection" that automatically detects if user has been in a car accident and automatically calls police or notifies emergency contacts. "Failure detection" should make a decision in a shorter time, and requirements for algorithm may be higher.
By way, you probably already know how to buy a smartwatch. Of course, as long as price is beautiful, more wellness features, better. Take blood oxygen detection as an example, after Apple Watch S6, flagship smartwatches such as vivo WATCH, Huawei GT2, Honor GS Pro, Huami Amazfit GTR 2 and GTS 2 use blood oxygen detection. At same time, price of a smart watch equipped with this function has dropped to 300 yuan, which is Amazfit Pop released by Huami Technology.
In future, smart watches should become a health terminal, and friends who buy smart watches should see well before buying.
