preface:

In recent years, the development of intelligent industry has been rapid. Many traditional industries in daily life have changed imperceptibly under the influence of intelligence. Although many industries are labeled as "intelligent", they still appear unsatisfactory in practical applications. In particular, some wearable products that have been labeled as "smart" have become the focus of current complaints about their weak functions behind intelligence, After several years of development, the market of intelligent and intelligent wear is also becoming saturated. How to effectively solve the problems behind the rapid development has become a headache for businesses. In this issue, the author brings an innovative intelligent wearable product, "Weile Xiaohei 3", and mentions that "Xiaohei" should be no stranger to wearable players. As the former crowdfunding king of the domestic intelligent wearable industry, Xiaohei is very attractive in terms of appearance, function and even endurance. Now Xiaohei has been upgraded to three generations. In addition to transforming the original monotonous ink screen into a more fashionable color screen, What breakthrough features will there be in terms of functions and even the bright screen endurance? Without much gossip, let's take a look at the differences brought by this innovative "Little Black 3"!

Packaging Introduction:

The first time I met the third generation of Xiaohei smart watches, the first impression of book style packaging is simple but very delicate. In terms of packaging materials, cardboard square boxes with excellent compression and shock resistance effect are selected, which are more environmentally friendly than the previous second generation of plastic case standard packaging. The packaging surface is treated with black matte coating and feels delicate and comfortable. A simple Velot logo is printed on the front of the packaging accessories, At the same time, the bottom is also matched with red, green and blue stripes.

On the back of the package, we integrated the information and parameters of Weidaohei 3. At the same time, we also set up a security label. Personally, the label material is not good enough, and the dotted line texture is too shallow. It is impossible to tear it off or it will break at once. It is also convenient for the blade to unpack. The package of Xiaohei 3 is designed to open the lid. When the package is opened, a green sealed bag will be seen first. In addition to the cool contrast color, the front also has a hollowed out WELOOP design. The whole package interior is quite novel. In terms of packaging fixation, Xiaohei 3 uses embedded positioning design and is fixed in the positioning slot with snap function, Although there is no flexible sponge in the lining, the body is embedded and placed smoothly, so it still performs well in stability. In order to better protect the screen of Xiaohei 3, a frosted protective film is also pasted.

Although the built-in accessories of the standard version of Xiaohei 3 are simple, they are still sufficient for daily wear. The inside of the package is equipped with the host meter, wrist strap, charging base, charging data cable, instruction manual and certificate of conformity.

Xiaohei Features:

The small black 3 has a circumference of 231.3x20x2.7mm, and weighs only 36 grams. It is very light without obvious encumbrance. The color of the head still follows the classic black elements of the previous two generations, while the appearance design is more rounded and plump than that of the second generation. In fact, it is difficult to see the changes of the new shape from a rough look, but you will find it when you look carefully at the case frame and screen, In terms of processing technology, Xiaohei 3 should be more refined. The metal frame brings a sense of harmony and at the same time, it has been processed by wire drawing technology, which can not only effectively avoid the wear of the frame, but also become more delicate in the hand feel.

Due to the influence of material and process limitations, it is common for smart watches to wear the mirror easily in the long-term wearing process. As we know from the market reaction of the previous generations of products from Xiaohei, the slight wear of the mirror has also occurred in the previous generations of products from Xiaohei, which is also a common problem of smart watches at present. This time, from the mirror process of Xiaohei 3, it is really a big change, The mirror surface adopts the popular 2.5D hyperbolic screen. The compact mirror surface is not only round and transparent, but also very transparent. The beautiful and semi transparent WELOOP can be seen through mirror refraction. In terms of material, the small black 3 uses Corning glass with outstanding abrasion resistance and scratch resistance. The Mohs hardness can reach 8H, which is more protective for daily wear.

Xiaohei 3 is equipped with an inch 1.28 inch eight color Memory LCD semi transparent screen with a display resolution of 176x176. Compared with previous generations of products, Xiaohei has changed from the original monotonous black and white color system to a more fashionable and mainstream colorful effect. From the actual performance, the screen effect of Xiaohei 3 is really extraordinary, and thanks to the full reflective display feature of Memory LCD, For outdoor, the stronger the strong light is, the clearer the screen display will be. At the same time, it supports the full display and constant light function to facilitate users to check, read and retrieve data at any time.

Nowadays, the traditional single entity key can no longer meet the user's control needs. More and more devices are added to the field of touch interaction. The Xiaohei 3 supports the two-way combination of entity key and touch in the control. The entity key adopts the left and right symmetrical positioning design. The left key supports the return/information, and the right key supports the menu/switch/confirmation, In terms of touch operation, Xiaohei 3 uses a capacitive screen made of G+F material, which performs well in operation feedback and has no obvious sense of damping. In addition, Xiaohei 3 also adds gesture operation functions, such as turning the wrist to light up the unlocking screen and turning information pages.

As a new model of Weile smart watch, Xiaohei 3 also follows the pace of the times in terms of function and integrates mainstream heart rate monitoring functions. It is monitored by a back contact photoelectric heart rate sensor. The heart rate sensor is positioned in the middle of the back of the watch, which brings better skin contact with the micro convex design. It is realized by the light refraction principle of the photoelectric heart rate monitoring technology (two sets of photoelectric), In terms of monitoring function, Xiaohei 3 points to two modes: static and dynamic monitoring. Compared with general photoelectric monitoring, it is more targeted, especially suitable for some players with high strength sports. The dynamic heart rate algorithm is not only more accurate than general smart watches, but also can feedback more professional motion analysis data.

In terms of charging, Xiaohei 3 still uses the magnetic suction charging base that highlights convenience, but the design of the base details is quite different. The surface of the base is sanded and then treated, and it also has good anti-skid and scratch resistance characteristics. The shape of the magnetic suction base is based on the half package design of the back cover frame of Xiaohei 3, and the magnetic suction connection is more stable than previous generations, The charging transmission is realized by the four symmetrical contact electrodes on the back and the charging base (USB data cable). The charging process is not only simple but also stable.

The standard version of the black wrist strap is made of soft TPU material, which can support the wearing of 140-210mm wrists. The inner side of the wrist strap is also equipped with a wave sweat slot for sports ventilation, which can give good consideration to both daily matching and sports wearing. The 3rd generation of Xiaohei continues the split design of the watch and wrist strap, which can be quickly replaced through the quick disassembly component of the wrist strap. In addition to the standard TPU wrist strap, Weile also provides colorful hollowed out wristbands for sports and cowhide wristbands for daily business use. The material and color matching can better meet the aesthetic needs of different people.

Software experience:

(Just a few days ago, a Weile NOW2 evaluation was released - because it is the same APP, it will be similar. If you have any questions, please contact me) "Weloop" APP The interface design is simple and refreshing, which can be divided into four categories: target, sport, device and individual in terms of function. After the basic information is entered, you can enter the Bluetooth adaptation link, open the mobile phone Bluetooth, search and click in the device page, and then connect. The entire operation connection process is simple and can be easily completed even by Xiaobai, In the experience of pairing and binding, the author encountered an embarrassing step. If the APP was bound to other Weile devices before, it must be unbound when binding a new device before pairing. Although the process of rebinding is very simple, repeated operations are still time-consuming. Can you add a disconnection selection function to the device?

After pairing the Xiaohei 3 with the mobile phone, you can see the top 10 operable functions on the device interface (call identification, schedule reminder, message push, Do Not Disturb Time, daily alarm clock, firmware update, my business card, basic settings of remote camera, and problem diagnosis). Among the top 10 functions, call identification is the least common and very practical in smart wearable products, This is also a special function brought about by the cooperation between Weile and Sogou. You can intercept harassment, marketing, fraud and real estate by accessing Sogou Tongtong. At the same time, it is also a tag number management and blackout function. Even the IOS system can be well compatible with the interception function of Weile, and it can help you to prevent harassment without installing software.

Daily reminders, message push, Do Not Disturb period, daily alarm clock and firmware update are quite common. In daily reminders, users can set multiple groups of reminders according to their own needs. In reminders, users can select the name and time of reminders. When the time arrives, Xiaohei 3 can vibrate the reminders; "Weloop" APP supports the push function of the current mainstream social software and essential messages of mobile phones, and it is also another push option (what does the other mean? It has not been understood yet). Users can select or close the push category in the message push; The Do Not Disturb period, as its name implies, is an anti disturbance setting. When the Do Not Disturb function is enabled, all information push except the alarm clock will be turned off; In the daily alarm clock, Weile is equipped with three groups of optional alarm clocks. In the alarm clock setting, the user can select the time and week. For the general population, the three groups of alarm clocks are sufficient. If not, they can be used together with daily reminders; Firmware update is a function of regular optimization and update for Xiaohei 3. It is very convenient to use remote download and installation for firmware update.

For business people, sending business cards is common. Now with Xiaohei 3, even if you forget to bring your business card, don't worry about it. After you add and set personal information through "My Business Card" in the device and save it successfully, you can generate a QR code and synchronously present it on the Xiaohei 3 dial. It's convenient to send a name card by scanning it? In addition, Xiaohei 3 has also added the feature function of remote control for players who love to take selfies. Even if there is no selfie pole or good base friends, there is no need to be afraid. Just connect Xiaohei 3 to achieve remote control remote photography.

Since the smart watch has brought the screen, the feature articles of the dial are also indispensable. With the dial changing function in the "Weloop" APP, the dial can be changed remotely for the Xiaohei 3. So far, the "Weloop" APP The types of dials are relatively rich, and the features of various dials are also comprehensive enough to meet the needs of daily wear personality. Because the small black 3 update adds color screen features, the screen display is more beautiful and realistic than previous generations of products. Of course, due to the screen material and resolution limit, the picture display is more or less exquisite, From the current experience, we can see that the "Weloop" APP has many and comprehensive screens, but in terms of personality and characteristics, it is not grounded enough. It is recommended to open permissions to add the function of self-made dials in the future.

The basic settings of the device cover the selection of the control function of the small black 3. Due to different user habits when wearing, the wearing mode is specially added to the settings for selection. From other basic settings, the versatility and selectivity of the functions supported by Weile are very high, such as backlight display suitable for night operation, wrist lift unlocking convenient for viewing information, There are also healthy and close to life sitting reminders, weather information, and mobile phone loss prevention functions. At the same time, the track function related to sports has also been specially added. In addition, the music player function with high convenience and control has also been added. Both the operating features and the functional effects are designed to be close to the needs of users. The comprehensive function performance is very pleasing to the author.

only Le is diligent in data integration management. From the goal of the APP, we can see the data of every time period today, as well as the detailed data of walking, running, picking, heart rate, sedentary and sleeping. Different data are distinguished by different colors, which is clear and easy to see. In addition, through the integration and analysis of sports data, You can also see the calories consumed by the user on the APP. In addition to the goal interface, you can also view the degree of completion within the use time through the calendar on the left. It is similar to clocking in every day. The goal data is displayed in green circles, and if not completed, it is displayed in orange circles.

In addition to displaying today's data on the target end, you can also access the activity chart interface through the icon in the upper right corner. The activity chart interface is divided into a movement chart and a sleep chart. The movement chart records the movement of a week (month, year) in a weekly (month, year) way, and then presents it in a graphical way. At the same time, the average activity heat, average kilometers Target rate, average steps, comparison, running training and other data. From the perspective of the integration interface of the motion data, the data is well organized and the record is very comprehensive. The biggest feeling is simple and clear.

The sleep chart is very similar to the movement chart in terms of the overall level of the interface, which contains weekly (monthly, yearly) chart data. According to the sleep quality, it can be divided into three states: deep sleep, light sleep, and awake. In addition to text differentiation, the depth level is also differentiated by color followed by time. At the same time, the average sleep time and sleep score can be viewed, It is well known that reasonable and sufficient healthy sleep can not only improve the working effect in the daytime, but also be very helpful to physical and mental health. The author is that the patients who sleep late go to bed at 1 and 2 a.m. every day, and get up at 8 a.m., so their working spirit in the daytime is not in the state. Wearing the little black second generation can better understand their sleeping state, Of course, it would be even better to add hazard warning.  

In the sports mode, the small black 3 has added the function of running and cycling cumulative distance, and has five built-in sensors to achieve movement monitoring and recording. When the sports function is turned on, the "Weloop" APP At the same time, the mobile phone positioning function will be turned on, and the image and text movement data will be presented more clearly and intuitively through the sensor combined with the positioning function. After the movement, the heart rate band changes in the whole process can also be known. Although the price of the Xiaohei 3 is not high, it is really comparable to the professional sports watch in terms of monitoring function, and the accuracy of the heart rate monitoring function is also quite good.  

The design of the data integration platform in the "Weloop" APP is really good. Even the best days, weeks and months can be clearly displayed. Even if the watch is unfortunately lost, the accumulated data can continue, and at the same time, the WeChat movement can be synchronized QQ sports and Apple health are really a table of data in hand. You can not only watch but also share it with your friends. In addition, a point system reward has been added to the sports goals. You can get one point for every 50000 steps (60000 steps=2 points, 80000 steps=3 points). You can use the points you can get to offset when you buy in the official mall, In addition to their own healthy sports experience, wearing Weile can also get material rewards from businesses, which is not a disadvantage to anyone.

Wearing feeling:

The biggest difference between smart watches and other smart wear is the display and control with a screen. Although more and more smart wristbands now add the screen display function, they are still not as considerate as smart watches in terms of real operation experience. Through the combination of entity and touch, the control of Xiaohei 3 can be achieved. In terms of interactive experience, Xiaohei 3 has added high operability Line icons with clear recognition, while the secondary menu is displayed in a two-way combination of text and icons. Before users operate, they need to understand the functions of each icon. The first screen interface mainly displays the time table (optional), and right click to enter the basic information interface of the watch (connection status, power status, and Do Not Disturb mode); Click the left button to enter the secondary function menu. Various icons have different functions (information push, heart rate monitoring, running training, cycling training, stopwatch, timing, music playback control, dial selection, mobile phone search and setting interface). The function booth is not only clear but also very considerate; The three-level menu is mainly used to select different functions, which will not be expanded here (see the picture for details); In addition, sliding up and down on the first screen interface also displays three functional interfaces (my business card QR code, weather broadcast interface, and sports data display interface, which are read-only and can't be manipulated). Users can choose different functions according to the actual situation. From the actual experience of Xiaohei 3, it can be seen that the various functions are highly playable.

In terms of wearing performance, the heart rate sensing detection function is added to the small black 3, so the integrated design of the back is high and uneven. However, the feeling of skin fitting is basically unchanged in actual wear, and there is no obvious stumbling phenomenon even if it slides up and down during wearing; The standard TPEE wristband is also very comfortable to wear, and both flexibility and wear resistance are very reliable. Of course, the standard wristband is still relatively small for focused adaptation, and its air permeability is not as good as that of sports wristbands; Fortunately, the small black 3 is light, so the wearing experience is very good. Even in winter, there is no obvious discomfort when wrapped in clothes.

Waterproof function is common in the smart watch industry, and the functions that appear to be common are also very exquisite in their internal process. Although the products are equipped with waterproof function as standard, the waterproof effect is also different. Besides the waterproof function, the user's main point is the waterproof grade. The Xiaohei 3 supports the 50 meter waterproof function, which tends to be a high level in the smart watch industry, In addition to satisfying daily life, users can take the Xiaohei 3 to swim, which just covers many waterproof scenes that are not supported by smart watches.

Although the Xiaohei 3 has added the full-color screen and heart rate function, it is rare that it has not reduced its endurance due to the addition of other functions. In this smart watch industry, the Xiaohei 3 is an alternative. The Xiaohei 3 has a built-in 270mAh lithium battery, which is not prominent compared with the battery capacity of ordinary smart watches, but the fact has proved that the endurance of the Xiaohei 3 is indeed powerful, The reasons for this are countless and unclear. In addition to the favorable hardware optimization and connection, the most important thing is the screen selection. Because of the low energy consumption characteristics of the Memory LCD screen, even if it is always bright all day, it can bring excellent endurance. The official gave the endurance of 40 days when the function is fully open. After several days of use by the author, it can be seen that the endurance of the Xiaohei 3 is really powerful, A total of 22% of the power is consumed in six days, including 20 minutes of riding every day and full open push. For users, the endurance is directly related to the wearing time. No one wants to wear a smart watch but needs to pay attention to the power.

In terms of data accuracy, the author made a simple test. Through the test and comparison of four types of movements, namely, swing, walk, run and ride, Xiaohei 3 is equipped with three types of motion sensors, namely, three-axis accelerometer, electronic compass and gyroscope, which can clearly identify and distinguish small movements. A slight swing of the arm will not count steps without starting, That is to say, the performance of the step counting accuracy is significant, and there will be no miscalculation; In the walking state, the actual 100 steps of walking, Xiaohei 3, shows 102 steps. From the feedback of data records, there are still some errors, but the overall performance is relatively satisfactory, and the difference is not very outrageous; The difficulty of manual step counting in running state can be imagined, so if you don't comment on the step counting data, you can refer to the walking data. In running state, the most attractive thing for the author is the dynamic heart rate monitoring function. The data generated by real-time heart rate monitoring is displayed linearly through APP; Finally, the riding data is generally reliable. The distance can be recorded through the "Weloop" APP GPS positioning, as well as the speed and heart rate data. The functions of both running and riding are basically the same, but the author still recommends using it with the pedal frequency collector, In terms of data, it will be more comprehensive and targeted.

Summary:

The third generation of Weile Xiaohei has no obvious distinction in the appearance design. More innovative breakthroughs are mainly reflected in the function. Although the third generation of Xiaohei is still black, the interior color has been completely different. The first is the change of the screen, from the original monotonous black and white screen to the fashionable mainstream colorful screen. In this age of looking at color, the colorful innovation and changes of the three generations of small black are really more popular with intelligent wearable users; The touch interactive function is added to the control design, which is not only convenient for daily experience, but also more grounded. The purpose of releasing both hands is being achieved by information scrolling. Of course, the recognition is still slightly insufficient, which needs time to run in; For users who like sports, the competition level heart rate monitoring joined by Xiaoheisan is just what they need. Through dynamic and static monitoring, 24-hour heart rate recording can be achieved, and at the same time, dynamic heart rate monitoring of sports players can be guaranteed. The combination of dynamic and static monitoring can bring more comprehensive and accurate heart rate data. In addition, Xiaoheisan also supports access to other third-party applications, Two way combination brings more professional data interface; The most amazing thing for the third generation of Xiaohei is the endurance. I believe that many users who choose the third generation of Xiaohei are going for endurance. The official theory supports 40 day endurance around the clock. Although there will be deviations in the operating frequency and push, generally speaking, there is not much difference. Compared with the smart watches that are charged every day, High endurance not only reduces the tedious charging process, but also improves user recognition. After all, smart watches are mainly for the convenience of users' lives, rather than charging them every day; If you like sports and prefer practicality, the Xiaoheisan is really a good choice. Although the appearance is not so compelling, it is really genuine. Compared with professional smart watches, it is not much better. Although the hardware configuration is more professional, the price of 488 yuan is very friendly to people.
