1, sports
In terms of function, Huawei bracelet 4 Pro has done a lot of work around the two keywords of "sports" and "health".
First of all, it is worth mentioning that Huawei bracelet 4 Pro has added an independent GPS function, which is superior to most bracelet products on the market. From the bracelet market, due to the limitations of product space design, power consumption and cost, there are only a handful of bracelet products supporting independent GPS function on the market at present. In outdoor sports, most bracelets still need mobile phones to locate the movement track.
Huawei bracelet 4 Pro can record outdoor sports tracks without connecting to a mobile phone through the built-in GPS chip. Its unique GPS function makes track recording no longer rely on mobile phones. Whether you are running outdoors or swimming in open water, you can record your trajectory by wearing a bracelet.
In addition to the blessing of independent GPS, Huawei bracelet 4Pro is also equipped with 1 1 intelligent sports mode, including outdoor running, indoor running, outdoor walking, outdoor cycling, indoor cycling, elliptical machine, rowing machine, swimming in the pool, swimming in open water and free training. 1 1 Large-scale sports mode, with comprehensive indoor and outdoor coverage.
In the 1 1 sports mode, Huawei Bracelet 4 Pro can provide different sports data monitoring, and can accurately monitor and analyze heart rate, pace, calories, swimming style, stroke times, SWOLF swimming efficiency, and even training effect, recovery time, maximum oxygen uptake, etc.
Through the running course on Huawei Health App, you can set and select different levels of sports goals, including four difficulty levels: primary, basic, advanced and intensive. In the process of wearing the bracelet, you can know the meaning of heart rate range, training effect, pace and pace frequency in real time.
During running, you can see the real-time exercise effect by raising your hand, and control the training intensity within a reasonable range through real-time exercise data to make the exercise more accurate and efficient.
During swimming, Huawei bracelet 4 Pro supports automatic recognition of swimming posture, automatic recognition of stroke times and automatic calculation of SWOLF swimming efficiency index. At the same time, it also supports the statistics of distance, time, calories, frequency and pace.
For indoor gym enthusiasts, Huawei bracelet 4 Pro provides real-time heart rate, calories and time of elliptical machine/rowing machine, as well as training effect and recovery time after training, so as to better record the movement of elliptical machine/rowing machine for users.
In addition, Huawei bracelet 4 Pro cooperates with the well-known sports algorithm organization FirstBeat, which can give more scientific sports effect evaluation and suggestions according to the user's personalized physical and physiological information and personalized data during exercise, such as VO2max maximum oxygen uptake, sports recovery time evaluation and calculation, aerobic training effect, etc. Through the analysis of professional algorithms.
2, blood oxygen saturation detection
Huawei bracelet 4 Pro has three "health management": oxygen saturation detection, intelligent heart rate monitoring and scientific sleep monitoring, providing users with all-round health protection. At the same time, the bracelet also supports the 30 1 hospital heart health research plan to protect the heart health of users. .
Oxygen saturation (SpO2) is the percentage of the combined capacity of oxygen and hemoglobin in blood to the total hemoglobin capacity, that is, the concentration of blood oxygen. SpO2 is an important physiological parameter of respiratory cycle and one of the important vital signs. If the oxygen saturation is lower than 90%, it will easily lead to fatigue, lethargy, listlessness and other symptoms, and even damage the body function in the long run.
Huawei bracelet 4 Pro deeply optimizes the hardware optical path and algorithm, integrates multiple light sources, and uses the different reflection and absorption rates of oxygenated hemoglobin and deoxyhemoglobin to perform signal extraction, signal enhancement, algorithm training, abnormal suppression, etc. to measure pulse oxygen saturation.
With a small device like a bracelet, the blood oxygen concentration can be measured anytime and anywhere, ensuring that the wearer knows his health status in real time and bringing more convenient and comprehensive health management. However, it should be emphasized here that Huawei bracelet 4 Pro is a non-medical device and cannot be used for diagnosis and treatment. The data are for reference only.
3. Heart rate monitoring
Huawei bracelet 4 Pro is equipped with Huawei TruSeen? 3.5 Intelligent heart rate monitoring and heart health management. This technology was independently developed by Huawei, and the algorithm was jointly developed by Huawei 20 12 Laboratory and Russian Research Institute. The heart rate monitoring frequency can be intelligently adjusted according to the movement state, and with the intelligent dimming algorithm, 24-hour intelligent monitoring can be realized.
This generation of smart bracelets will continue to cooperate with the heart health plan of 30 1 hospital, comprehensively judge the jump-by-jump premature beats based on the rule method and artificial intelligence algorithm based on expert experience, and cooperate with the MAFA system of 30 1 hospital to provide closed-loop management services for suspected high-risk users, realize 24-hour premature beats screening, and further bring health protection to users.
Based on the high-performance heart rate sensor of the bracelet, Huawei bracelet 4 Pro also supports the heart health research plan of 30 1 hospital, a famous domestic tertiary hospital, which can accurately screen arrhythmia and cooperate with high-precision AI algorithm to connect with the professional services of 70+ hospitals. The accuracy of atrial fibrillation screening is as high as 97.8%.
Combined with 30 1 hospital remote management service platform, it provides users with arrhythmia diagnosis, treatment and follow-up services, so that users can realize one-stop service of arrhythmia. And you can add a list of friends and relatives in the App, so that even if you are not at home, you can know some of their physical health (especially heart health).
4. Sleep monitoring
Huawei bracelet 4 Pro is equipped with Huawei TruSleep? 2.0 Sleep detection technology can monitor the user's sleep structure and state all night, accurately identify six typical sleep types such as difficulty in falling asleep/shallow sleep/easy to wake up at night/early wake up/dreaminess/irregular work and rest, and provide 200+ sleep suggestions, sleep music, relaxation and decompression services to improve sleep habits.
5.NFC and mobile payment
Huawei bracelet 4 Pro brings NFC access card, bus card and Alipay mobile payment function, which supports the opening of bus and subway cards in 250+ cities nationwide, and pays when traveling by bus. Support to copy the access control keys of most door locks in residential areas, garages, elevators, etc., which can be opened by raising your hand (OTA upgrade support); Support Alipay offline payment, it is easier and more convenient to raise your hand to pay.
6, Bluetooth music playback
Huawei bracelet 4 Pro supports Bluetooth music playback.
