Smart wearable devices are now flying everywhere, especially smart bracelets. So there is this topic. This article is not detailed drying of the bracelet, after all, Aunt Zhang has this sunburn. Simple and objective (try to) talk about this topic. Talk about the bracelet, each APP function is similar, do not start the discussion, or I will be exhausted screenshot.
Three dimensions- Usage scenarios (functional requirements)
- Budget
- personal taste
Usage scenario (functional requirements)Roughly divided into three subcategories
- Sports monitoring
- Status alert
- Health monitoring
Sports monitoringMost of the bracelets currently on the market are presented to the general public in the form of sports bracelets, so sports monitoring is now the standard feature of most bracelet products.
For most wristbands, an acceleration sensor is basically the source of all your motion data. The information of a multi-axis sensor is processed by the wristband or matching application and will present you with a pile of so-called motion data. The algorithms of different brands are inconsistent, so the specific data may be different, but since you can buy it in the market, it proves that the deviation is not too big.
Primary function:
- Step count
- Mileage
- Calories
Since you are wearing a wristband instead of a foot ring, if you do not choose the sport mode, if the wristband does not have intelligent motion pattern recognition or other good noise removal algorithm, then in the more complex sports environment, even the most None of the basic steps can be identified correctly (in fact, for most people, this step is more practical than social media such as WeChat, sports, and friends). The calorie calculation is even more metaphysical, and each person's physiological condition is different. With a single sensor plus an algorithm model built around age, height, and weight, you can measure how much calories you consume? If this is to get the correct value, then the bracelet definitely needs more different types of sensors (such as heart rate, increase the input of effective information), and a model that can learn to evolve autonomously based on your long-term exercise. Of course, it is best to add Correct the actual value. These conditions are unrealistic for the vast majority of bracelets for ordinary consumers. The above values ​​exist purely to satisfy the user's need to display data in order to see the data (and possibly propaganda-driven). MIO recently came up with the concept of PAI. Although I personally feel that the publicity is slightly involved, at least this direction is my recognition.
Therefore, we must first have the data to look at an idea that is appropriate, proper exercise, and happy. Otherwise, you can buy it.
Advanced features:
- GPS/pneumatic/temperature/geomagnetic...
- Heart rate monitoring
- Sports coach
For those who have higher requirements for the sports bracelet, more different types of sensors can give you more effective information, such as GPS/pneumatic/temperature/geomagnetic/heart rate sensors. The data presented to you is real-time. direct. Instead of being similar to the primary function, it is presented to you after being processed. For all kinds of sports veterans, these data are more valuable. The function of heart rate monitoring is worth mentioning. In some strenuous exercise, you can set the threshold value to make your body condition controllable. Of course, these user groups can basically find their own professional sports brands and purchase suitable sports equipment.
At present, there are some brands on the market. Both the GPS and sports coaching functions are devolved into ordinary bracelets. As far as the results are concerned, basically Bojun laughs. It would be nice to make a record of the movement path, but usually the wristband is connected to the mobile phone, and the GPS of the mobile phone completes this function. For ordinary users, the guiding significance of using the independent sports coach APP is greater than the matching application of the bracelet you bought. Naturally, Runtastic and Endomondo are not free lunches.
Status reminderStatus reminders generally fall into two categories
User-Bracelet
- Sports progress reminder
- Sedentary reminder
Mobile Phone - Bracelet
- alarm clock
- Anti-lost
- Call/SMS alert
- APP message alert
These are the basic functions of the bracelet on the market. Of course, in fact, many people around me want a bracelet to just want a silent alarm clock, and other functions should be sent. Is it a bit like buying a beggar, people still think that other features cost electricity, in fact, the best is the right one. Try to be clear about your needs before buying to avoid unnecessary annoyances.
Speaking of this, I couldn't stop myself from tweaking. There are even some brands on the market that have lost their wristbands. The application scenario is that the phone is on the body and the bracelet is gone. Click on the APP and the wristband vibrates. I don't talk about the problem of your bluetooth disconnect. Can you hear what you're doing? How high is the motor adjusted? This kind of deposit is designed to have this function. I really can't figure it out.
Health monitoringThis feature is generally added to the list of older people's wristband functions, and brands currently placed in the general product line are also currently on the market.
- Heart rate / blood pressure / blood oxygen
Each uses different sensors and different algorithms. Therefore, specific accuracy is not evaluated. It is generally considered that single-point PPG is not very likely to get very accurate values, so these people can be used as a daily reference, and the higher the accuracy is, or to find professional equipment.
Different devices support different heart rate measurements, some support dynamic measurements, and some support only static, so for friends who love sports, may wish to buy a professional heart rate belt (of course, MIO seems to advertise that the heart rate accuracy is 75%, not as good as it Watches fly.
As for blood pressure, static values ​​are measured. The measurement environment is more demanding, and generally the first measurement is taken together with professional equipment to obtain calibration. Personally, for this kind of data, a better way to deal with this problem is to save the sensor's raw data and pass it to a professional data platform for processing, so that accurate values ​​and medical advice can be obtained over a longer period of time. Qualcomm looks like it has been doing its platform, Qualcomm Life, different hardware manufacturers and medical institutions can access. It is not clear whether there is a similar platform in China.
other functions- Sleep monitoring
- Mobile payment
- Authentication
Wait
Sleep monitoring. Not to mention the accuracy of sleep monitoring, assuming APP is useful for my sleep report, can you give me effective advice on the report you give? So, in the final analysis, it is still an all-in-one function.
Mobile payment. Except for a few brands that have PY transactions with banks and Alipay, other brands usually do not cover mobile payment functions in a broad sense. This is not a technically high threshold, but the death of a qualification card. There are a variety of custom bracelets that can be consumed in a specific consumer environment. Usually the higher usability is some of the bracelet brands that cooperate with public transportation, brush bus subway, save the Leica's process (basically you can brush your phone).
Authentication. Using chips such as RFID chip, NFC or BEACON (easy to change data) in the wristband, the chip can be used to complete identity authentication with the supporting system. Typical application scenarios are access control, membership cards, and electronic business cards.
budgetThere is no difficulty in the world as long as you are willing to spend money.
There is a psychologically expected price for buying things, so a preliminary understanding of market conditions will help you set a more reasonable psychological price.
For users with a brand complexion (propensity), that is the simplest choice. Go directly to the official website to see the price of all its bracelets, buy your favorite one, over. After all, faith cannot talk about price.
For most of the users who do not have a strong brand inclination, we can roughly classify them with price ranges and domestic and foreign brands.
It can be simply assumed that foreign brands are more expensive than domestic brands, and we can simply call them wearable. (In fact, the design sense of foreign famous brands that you can see is indeed much stronger than that of domestic ones.) More than 500 yuan budget proposal directly to foreign brands, there are not many domestic brands dare to take this price.
For most domestic brands of smart bracelets, we can set the price range to 100, 200, or 300.
Less than 100 - Available
Covers basic functions. Give you steps, mileage, calories, alarm clock to remind you to go out next door Pharaoh, a ventilation you know the phone comes, then pump you know WeChat was looking for. This is probably a setting. Some even have static heart rate monitoring (although I do not know what use), of course, some brands also have some of the functions associated with their own other equipment (system).
200 or so - useful
This is the most active range you can see in the current market (after all, left and right). Basic functions are all, static / dynamic heart rate monitoring, [blood oxygen, blood pressure], there is usually a black and white small screen for you to push a variety of application messages.
In this price range, there is a difference in the various brands, some support mobile payments, some support public transport subways, and there are some weird brand special features. For the average consumer, you can find a bracelet that meets your functional needs in this price range.
300 or so - easy to use
Better/more sensors, better screens (and possibly larger, accidentally watches), legendary designs, better services, brand points. More quality sensors mean more possibilities to be combined and more profits mean better service and design.
Personal tasteSay a thousand words, and finally found that the enemy is not like a moment.
So I list this last. Just like your mother told you to go blind, this girl is very suitable for all aspects of your life, but what's the use for it? Just don't like it.
Good, hypocritical words come out, and finally hope to quantify some indicators to describe the taste.
thicknessWhat people wear on their hands is very sensitive to thickness. The thickness is usually determined by the material and the sensor. The metal structure is generally thicker than plastic, and the heart rate sensor is thicker than none.
The structure of the host, metal, plastic, metal + plastic. Wristband material, PVC, TPU, TPE, TPSIV, silicone, rubber, etc.
The material and design of the mainframe largely determine the texture of the entire bracelet, and the material of the wristband determines the comfort you wear. We may not understand the meaning of the terms wrist strap material. I can't force it to say which one. I suggest you try it out. Apple crickets should use TPE. I personally do not require high, not allergy + soft, so MIO Alpha that dough-like strap I love to the sky. Fitbit Surge is also good. Of course, these two things that can be called professional sports watches we do not put in comparison. Not an order of magnitude, I'll talk about the material of its wristband.
colourMost of the bracelets are black and white, so for some of the bracelets that have a color choice may get some people's preference. I just want to say something about this, please bring a wristband.
I would have liked to talk about the shape of the mainframe, but the equipment on the market is basically a straight strip. No matter if it is worth mentioning, if you like it, it will attract you at a glance.
Bracelets and watches This section is chaotic, because with the bracelet from no screen to screen, the screen from small to large. This line becomes more and more blurred. Due to the size of the sensor and the problem of information presentation, the professional portable exercise equipment generally has a large screen.
I think this can be classified. Smart bracelet - smart watch - smart watch.
After determining what you want, take a look at the wallet and buy what you like most. In fact, you do not need me to help you choose.
Anyway, personal favorite of this alarm clock, no screen metal face with slim body. Um, very good.
