Is it better to run with a bracelet or a sports watch?

Sports bracelets and sports watches are typical representatives of smart wear. The price of sports bracelets is much cheaper, ranging from one hundred yuan to several hundred yuan, while the price of sports watches is much more expensive than bracelets, ranging from a few hundred thousand yuan cheaper to thousands more expensive. What's the difference between them? How should runners choose bracelets or watches?

The bracelet represents the low end.

Does the watch represent the high end?

In the eyes of many people, bracelets often mean cheap and simple functions, while watches are synonymous with high-end atmosphere. Is that really the case?

This may have happened a few years ago, because the bracelet of that era had almost only the function of counting steps, but today's bracelet has completely got rid of the defect of single function. With the development of smart wear and sensor technology, the smart bracelet has been upgraded, and the bracelet has achieved more than 70-80% of the functions that sports watches can achieve.

For example:

The watch is a color screen and the bracelet can also be a color screen;

The watch screen is high in pixels, and the bracelet can also be high in pixels;

Watches can tell time, and bracelets can also tell time;

The watch can measure heart rate, and the bracelet can also measure heart rate;

Watches can record running mileage, and bracelets can also record running mileage;

Watches can be paid mobile, and bracelets can also be paid mobile;

So it is not an exaggeration to say that there is no essential difference between a bracelet and a watch. In fact, from the perspective of engineering technology, integrating chips, integrated circuit boards and sensors is called smart wear.

Some people say that bracelets and watches are mainly different in appearance and shape. Round watches are bracelets. This is probably because the earliest watches and bracelets were made in their present shapes, so everyone agreed to call them that. Appearance is one of the characteristics of products, but it is not the essence to judge the quality, grade and function of products.

Bracelets and watches are the most important and core hardware components of wearable devices at present and for a long time to come. Now or in the near future, there will be more forms of wearing, such as smart hardware worn in ears, arms, legs or other parts of the body.

But in general, from the aspects of user experience, wearing comfort, accessibility, and users' viewing at any time, bracelet watches still have irreplaceable important advantages.

As far as wearing comfort is concerned,

The bracelet may still have an advantage.

Because the dial of a watch is relatively large, it may not be as good as a bracelet in wearing fit, especially for some outdoor or triathlon watches, which have a large dial and are particularly thick because of the built-in sensor.

For men, there is a clear sense of heaviness after wearing it. Of course, many people still enjoy this feeling, but the bracelet is different. The bracelet is naturally annular in appearance, so the core part of the bracelet can be designed as an arc, which can better fit the wrist, so it feels lighter and more comfortable to wear.

If the overall experience of the watch and the bracelet is not much different when worn at ordinary times, then in the measurement of sleep mode, the hand is slightly superior to the watch. Wearing a slightly heavy watch when sleeping, it probably feels worse than a light bracelet.

Functionally, watches are relatively more powerful.

But not all functions can be really used by users.

Whether there is a difference between the functions of bracelets and watches is a key issue.

Smart watches on the market can be roughly divided into two categories:

One is based on Android, Apple and other mobile phone operating systems, which has the function of independent calling and surfing the Internet. In essence, it is a miniature smart phone, which can be regarded as a watch-shaped mobile phone.

The other is that there is no independent mobile network module, and other smart devices must be connected, which can receive incoming calls/SMS notifications from smart phones and realize Bluetooth transmission with mobile phones. The bracelet is roughly the same.

Watches are usually more expensive. In terms of satisfying users' feelings, manufacturers will also provide more functions than bracelets in functional design. The round dial of the watch is larger than the long strip design of the bracelet, and more sensors can be built in. The internal space of the bracelet is relatively limited, so it is impossible to make it thicker and thicker. Therefore, in terms of functional design, watches are still slightly better than bracelets.

Of course, powerful function is one aspect, but whether users can make full use of the rich functions of watches has become another industry pain point-how to make users make full use of the powerful wearable functions and get a better user experience.

In fact, a considerable proportion of users only use 20-30% of the functions of watches in actual use, and many functions are rarely used or not used at all. So for many pragmatic consumers, a simpler and more direct bracelet can realize most of the functions of sports watches. The key is that the price is still cheap. Why not?

Which is more accurate for measuring heart rate and other indicators?

The measurement accuracy of important parameters such as heart rate and distance does not depend on the bracelet watch itself, but on the measurement accuracy of sensor technology and algorithm optimization.

As the mainstream of modern bracelets and watches, photoelectric technology (PPG) can only say that everyone's measurement of high heart rate is not very accurate.

There are many factors that affect the heart rate measurement accuracy of photoelectric bracelet watches, including the displacement of non-pulsating physiological substances such as skin and muscles, skin color, light signal data, etc. These data are usually in the same interval as the swing arm frequency or step frequency (140- 190 steps/min), and the wearing position, etc. These factors often lead to insufficient measurement accuracy of photoelectric technology in the high heart rate range, but it is generally accurate in the middle and low heart rate range.

Constantly optimizing the heart rate algorithm to improve the accuracy of heart rate detection is also a problem that wearable manufacturers try their best to solve.

Measure running posture

Watch bracelets show their magical power.

No matter whether a watch or a bracelet is worn on the wrist, it is doomed that the parameters of running posture that can be measured are very limited, and generally only the parameters of step frequency can be provided (the step frequency is based on the period of arm swing or induced vibration, and the step length is deduced according to the speed and step frequency), so how to obtain more running posture parameters that runners want has become the time for manufacturers to show their magical powers and show their technical strength.

Some manufacturers have built-in motion sensors in the heart rate band, or fixed the sensors at the waist. Because they are fixed on the trunk at this time, they can measure running posture parameters such as height of center of gravity and touchdown time.

As the top high-tech enterprise in China, Huawei has always performed quite well in the wearable consumer market. In 20 18, Huawei officially launched the running bracelet, namely Huawei Glory Bracelet 4 running version. The latest version is Huawei bracelet 4e.

Huawei's solution is to wear it on your hand as an ordinary bracelet, and you can measure your running posture by buckling an accessory on your shoelace when running.

The running posture bracelet can measure running posture parameters such as landing mode, impact force, landing time, valgus range and swing angle. Especially for the measurement of foot movement mode during running, the data is rich and comprehensive, which can effectively help the public evaluate running posture.

Moreover, Huawei continues to innovate bracelet algorithms. Huawei bracelet 4e can measure the running posture during running and can be fixed on shoes when playing basketball. You can also measure data such as jump height and jump times. In the future, Huawei will develop more bracelets according to the measurement of different sports modes.

Huawei, which is wearable and comes from behind, leads the industry.

In the wearable field, Huawei is not the earliest entrant. However, after Huawei joined, relying on its strong R&D and manufacturing capabilities, Huawei has undoubtedly become an industry leader in terms of both shipments and product quality. Huawei is one of the few manufacturers that keep pace with bracelets and watches and can provide users with excellent products. It walks on two legs and walks fast and well.

As a high-tech enterprise with a strong engineer culture atmosphere, Huawei's ultimate pursuit of product innovation and willingness to invest in R&D are the fundamental reasons for Huawei's rapid iteration of bracelet watches, which constantly brings surprises to users.

During the open day of the Sports Health Science Laboratory of Huawei Xi 'an Research Institute, many media including Huirun were invited to visit one of Huawei's professional laboratories engaged in wearable product research and development, testing and verification. We also witnessed a large number of advanced scientific research equipment in Huawei Health Science Laboratory.

Teacher Dai, the author of "Running Without Injury", was invited to participate in the wearable roundtable discussion.

The exercise cardiopulmonary test platform is mainly used for aerobic capacity and walking test.

Optical capture test system mainly analyzes complex motion.

Golf simulation equipment provides a basic test platform for Huawei bracelet golf function.

In the wearable product reliability test experimental area, engineers will use mechanical equipment and software tools to simulate a variety of extreme usage scenarios and destructively test the service life of Huawei smart wearable products' hardware and software.

There are hundreds of these test items. Among them, a quarter of the test items are extremely destructive tests, which effectively help to improve products and improve product reliability and performance. After reading this, you will know why the quality of Huawei products is excellent.

Thanks to the powerful R&D, the richness and iteration speed of Huawei's wearable product line have made great progress in the past year or two. Huawei GT series watches have also become one of Huawei's explosive products and established a good user reputation.

What innovative features does Huawei have compared with other wearable devices?

At present, most Huawei bracelet watches can provide the unique function of heart health testing. On the one hand, it can detect the heart rate for a long time, on the other hand, it can let the public further measure the heart work when the heart feels uncomfortable and when it is needed at ordinary times, thus providing a practical tool for early screening of atrial fibrillation.

Its achievements were released at the annual meeting of the European Society of Cardiology and the World Cardiology University, which is undoubtedly an important achievement of the perfect combination of wearable technology and public health. In the future, wearable technology can not only provide exercise testing and recording, but also provide a powerful tool for people's daily health behavior monitoring and health risk screening.

In addition, Huawei's upcoming WATCH GT 2 Pro ECG model is equipped with ECG detection for the first time, which can directly measure ECG signals through the back electrode and side electrode of the dial;

On this watch, Huawei integrated and innovated the technologies of photoelectric (PPG) and electrocardiogram (ECG), and established the function of blood vessel detection. Compared with arteriosclerosis detection, it has higher accuracy and reliability.

Vascular function is an important indicator of cardiovascular health. Previously, it could only be tested with expensive equipment. Now this watch can directly measure your vascular health, which is a great innovation brought by technological progress to people's healthy life.

Engineers demonstrate the accuracy of blood vessel function detection of GT 2 Pro ECG.

Huawei attaches importance to user experience. For some runners, the accuracy of Huawei bracelets or watches sometimes drops when measuring high heart rate. During the open day, Huawei also said that the accuracy of heart rate measurement will be greatly improved in the new products listed next year.

There is no perfect product, only by constantly listening to users' opinions, constantly reflecting on themselves and constantly improving their own manufacturers. In this regard, Huawei listened to users' opinions frankly and patiently, and praised Huawei!

I also hope that in the future, Huawei can provide more accurate, smarter and more wearable products for the public and sports enthusiasts!

Should runners choose bracelets or watches?

Finally, we have to answer the runner's key question, is it a player's ring or a watch?

Watches don't necessarily represent high-end. Similarly, the bracelet does not necessarily represent the low end. The function of the bracelet is becoming more and more powerful, and it is almost the same as that of a watch in function realization.

For 60-80% ordinary runners who only record running mileage and heart rate, a few hundred yuan bracelet is enough to meet functional requirements;

For 20-40% experienced runners who need more complex functions, such as setting up training plans, a watch with more functions and more powerful functions is the best choice.

Because watches are still much more powerful than bracelets in terms of interactive design and functional diversity, this can also be reflected in the price.

But unfortunately, 80% of mass runners only use 20% of the functions of sports watches, and the other 80% of advanced functions are not used, so manufacturers should not only sell products, but also pay attention to user service.

How to make users use products better and enjoy the healthy and beautiful life brought by technology is a major issue for all manufacturers.

Because consumption depends on people's wishes, trends and expectations for a better life, from the point of view of general rational consumption, the bracelet of junior runners is good enough, while watches are more suitable for mature or experienced runners.

abstract

Bracelets and watches are also constantly being iteratively upgraded, and their functions are becoming more and more powerful. The sports bracelet can meet the general sports recording needs of the general public, and the watch is more powerful in interactive experience and function setting, which is more suitable for deep sports enthusiasts.

Bracelets and watches are both wearable classic representatives, and their positioning, functions and user adaptation will be different, and they cannot replace each other to meet the diverse needs of users.
