Xinlou: Huawei's seven-year building journey of sports health

A few years ago , We once attended a smart phone seminar .

At the meeting, the host talked about various so-called “ Black science and technology ”. The result is in the discussion session , An older teacher expressed reservations . He said , At our age , The only black technology you want , When can you watch your heart rate and blood pressure on your mobile phone at any time .

Many years have passed , Measure your heart rate with a wearable device 、 Blood oxygen , Even take blood pressure and ECG , It has become a reality one after another .

hold “ To ask for ” Become a reality , Huawei sports health . these years , Huawei's wearable devices have evolved rapidly in the field of health , The extent of progress , It has long been recognized by the industry and the market . We probably won't change a cell phone every year , But many people are willing to buy one for their parents, relatives and friends as soon as possible 24 Hour electrocardiogram , Or a wearable device that monitors blood pressure at any time . Strong rigid demand , Let Huawei keep healthy in sports “ Breaking circle ” More people know about . And support a good market response , It is they who have carved out persuasive technologies and products time and time again .

if , Which story is particularly suitable for us to enter Huawei Sports Health , Walk into the causal logic behind those newly needed technologies ,TruSeen It may be a suitable beginning of the story . Start with this word , We will enter a “ Seven years and Five Dynasties , Just to understand a heartbeat ” The story of .

This is a story of building . A group of people use sensors , Use algorithms , With big data , In the pulse of hundreds of millions of users , It has built a city about technology and health —— Heart tower .

In the light jump , Life is the most important thing

TruSeen Two key words , When it is disassembled, it is “ Really see ”. What do you really see ？ It is to see the secret information revealed by the explicit data of the human body . Inside and outside our bodies , Under various life signs , There are a lot of data . One of the most important data , It's the heartbeat . This fluttering light jump , It's not just evidence that we're alive , Emotional expression , More about endless health secrets . By reading the meaning behind the heartbeat , Perhaps we can confront or even defeat one of the most stubborn enemies of mankind .

2021 year , The First Affiliated Hospital of Xi'an Jiaotong University released a research data , Which indicates that in 204 In the country , The number of cardiovascular deaths caused by unhealthy diet in China is much higher than that in other countries , More than every year 700 ten thousand people . Among all the fatal diseases .

Burstiness 、 Unpredictability , It is the most terrifying place of cardiovascular and cerebrovascular diseases . Objective needs of heart health , As a result, the heart health monitoring equipment that can be worn for a long time is irreplaceable . We can also see the bracelet for many years 、 Wrist health equipment represented by watches has become the mainstream of the market . However, analyzing product capabilities and technology boundaries in the market , You will find several problems difficult to solve ：

1. Most heart health monitoring devices can only detect the heart rate per minute and whether the heart rate is stable , The function is actually very elementary .

2. Most heart health testing devices are affected by environmental factors , Produce misjudgment and misreading .

3. It is difficult for the heart rate detection equipment to fit the motion scene , The accuracy of exercise heart rate monitoring is low .

Heart health monitoring , It contains the weight of life , The weight of responsibility .

To cross these pain points , Truly unlock the infinite secret behind that heartbeat , There may be no other way but to make the best of the technology . And in order to achieve this goal , Huawei has decided to fight a veritable and protracted war .

Building in seven years , For a long time

As early as 2015 year , Smart phones are still in the period of popularization , At home 4G The network has just begun to be laid at the county and township levels , Huawei has seen the use of sensors 、 Algorithm 、 Big data to gain insight into the future direction of body information . This pre judgment across the entire mobile era , Let Huawei reap huge market space now , And more possibilities for the next era .

This software and hardware technology brought by intelligent terminal , The technology of interpreting human information , It's called TruSeen.

2016 year , Huawei has realized the function of static heart rate detection , This is also the starting point for Huawei to make sports health and wearable devices . Next , here we are 2017 Nianhua began to extend the detection of static heart rate to dynamic heart rate . This key breakthrough , So that users can pay attention to the heart rate changes during exercise , And the heart rate during sleep . The basic functions for heart rate detection have been completed . Most wearable devices in the market are also concentrated in this technical range , But Huawei feels that it is far from enough .

2018 year , Thanks to Huawei watch GT Series watches have long endurance technology upgrade , Huawei sports health has realized the measurement of heart rate 24 New function of hour monitoring . This ability can be more 、 A wider range helps users observe... Throughout the cycle 、 Find problems in your heart rate , Do not miss any health factor . The long endurance technology also supports more health detection functions . The human body is a comprehensive life system ,TruSeen The scope of attention began to expand and extend to the depths of life .

2019 year , Huawei sports health has launched the blood oxygen saturation detection function in wearable devices . This function, combined with heart rate detection, brings a very diverse value . Sports enthusiasts can use it to monitor sports , Determine the intensity of exercise ; The party who stays up late with busy work can pay attention to the lack of oxygen in the body , Prevention of health risks ; The elderly and the postoperative population are weak , Easy to reduce blood oxygen , It can be used to pay attention to . Even in 2020 After the outbreak in , There are also unexpected changes in the function of blood oxygen detection . At the beginning, nucleic acid and other detection methods were not mature , The decrease of blood oxygen is an important indicator of new crown infection . At this time, Huawei's wearable devices played a key role in the fight against the epidemic .

To 2020 year , Huawei will further TruSeen Technology evolution , Achieved support ECG ECG monitoring function , This function is applicable to the elderly 、 Friends with heart health problems are good news . It's solved 24 Hour ECG equipment is bulky 、 Inconvenient and expensive problems , The heart health capability of intelligent wearable devices has really stepped into the medical level . meanwhile , Huawei sports health has also changed blood oxygen monitoring into continuous blood oxygen . The blood oxygen detection algorithm used to consume a lot of power , But through technology improvement and algorithm optimization , Huawei finally makes continuous monitoring possible . It was not long ago 2021 year , Huawei also launched the monitoring function of blood oxygen at high altitude . More screen level Publishing , It is Huawei that has launched wearable blood pressure measurement capability , The air pump and other monitoring components are miniaturized and intelligentized . This makes TruSeen Another big step forward , Into a whole new field .

from 2016 year TruSeen1.0 Support static heart rate monitoring , All the way to 2021 year TruSeen5.0+ The accuracy of dynamic heart rate is improved , New high altitude blood oxygen monitoring capability , Support blood pressure monitoring .

It originated from curiosity about a heartbeat , Finally, many recognized medical level capabilities are brought to the wrist of users .

“ Seven years and Five Dynasties , Just to understand a heartbeat ”—— This may be a miracle in the history of intelligent terminals , It perfectly interprets what is called Huawei style long-term service .

Wrist carvings , Exhausting details

if TruSeen It is a high-tech building originated from the heartbeat , So what really supports this building to climb layer by layer , I'm afraid it's not just a technical breakthrough of reinforced concrete type , But for all kinds of technical details 、 The exquisite carving of product details . Sports health data is originally a kind of unstructured , It contains the data of many interference factors and environmental factors . Want to crack it , It's not just code stacking , It depends more on understanding user habits , Understand environmental factors , Understand body functions .

TruSeen Seven years and five generations , The core point is that the algorithm can read more and more information , More and more accurate , The energy consumption of the algorithm is continuously reduced . This is a “ Heart tower ” A beam of . besides , More details are needed , Endless details .

for instance ,TruSeen The hardware capability of is constantly breaking through . In the heart rate monitoring scenario , Everyone's wrists are different in thickness 、 Skin color difference is actually a huge challenge . Some users have thin wrists , Watches flip up and down easily 、 slide , This is likely to cause changes in the distribution of subcutaneous capillaries monitored by the sensor , Finally, it will affect the results of heart rate monitoring . In order to overcome this difficult problem ,TruSeen5.0+ In the technical upgrading, the ring sensor design is adopted . This can increase the contact area between the sensor and the skin . Blessed by intelligent algorithms , The sensor can actively judge the monitoring position with the smallest error , Minimize interference errors , Ensure that users of different body types can get accurate monitoring results . Combine again by 4 The channel is upgraded to 8 The circular optical path of the channel is used to design the heart rate module , Sensors with cohesive design , And a series of more ergonomic hardware design , Finally, the anti-interference ability of heart rate monitoring is continuously improved .

Accurately monitor and interpret heart rate , Not only basic software and hardware capabilities are required , More user data is needed 、 Exercise health data 、 A great deal of research on environmental data . for instance , The characteristics of the user's wrist have a great impact on heart rate reading , This is especially true when monitoring heart rate during exercise . The sliding of the device between the wrists 、 swing 、 Wrist position , May affect the accuracy of the results . In order to overcome this problem , Huawei's R & D team is very interested in the wrist bone structure 、 Skin colour 、 Wearing tightness has been deeply studied .

Fine wrist research based on different scenes , The sports scenes supported by Huawei watches are gradually expanding to a more professional direction . Only in the most well-known running sport , It is divided into interval running 、 Sprint run 、 sprint 、 Long distance running and other scenes . A lot of data testing and algorithm optimization are carried out in every detail , Finally, Huawei's sports and health equipment has become an understanding user 、 Understand health 、 An intelligent device that understands sports .

Data collection for these segments 、 Feedback test 、 Supply system iteration , Many of them do not belong to the scope of sports health research in the traditional sense . But for the ultimate realization TruSeen Breakthrough , Realize a deeper understanding of the secrets of the body . Huawei has chosen cross-border for all applications , To study sports , Study posture , Research materials , Study the wrist .

Final ,TruSeen It has become a health flower carved between the wrists .

Above the heart tower , The boundless age

There was such a judgment a long time ago ,20 The 21st century is the age of electronics ,21 The th century is the age of biology . Now , I believe everyone is aware that in today's world , How important are the factors of health and disease . and 21 The fastest growing technology market in the 21st century , It may also be an unimaginable large health market .

In the context of the era of great health , Wearable health equipment has become the most fully integrated technology 、 The science and technology category with the most obvious value of cross-border cooperation . This is also reflected in the shipments of wearable devices .
