Introduction  

As a matter of fact, I was so happy to receive the winning text message from Lei Feng.com that I felt like I had won a prize (actually I didn't win a prize, hey hey hey hey). I didn't win any prizes at the company's annual meeting. This prize is quite big for me. It's Lei Feng who cares for me! When I started to communicate with Lei Dada (Lei Feng.com), I only focused on the technology news of Lei Feng.com. At that time, I often focused on mobile phone evaluation. Last year, I accidentally found that Lei Feng.com still had evaluation services, because I had applied for a trial on a certain website before, but there were too many people on a certain website, and the application was basically not tried. The trial on Lei Feng.com found that there were only two or three thousand people applying for the trial, and the number of people was relatively small. It seems that the success rate is relatively high. Since last year eleven After taking part in an open class organized by Lei Feng.com in September, we began to try it out on Lei Feng.com. Fancy winning! This has greatly improved my confidence! After the Spring Festival, because I want to buy a smart watch that can display the time, I often pay attention to the trial of the watch. I also applied for Tuman and inWatch Two, found InWatch He was killed some time ago, leaving only the Tuman smart watch. He didn't hope much, but he actively participated. But unexpectedly, he won. It is said that the winning lot must have strong induction ability. Because I am in urgent need of smart watches, I have prepared to acquire a watch that displays time, the second generation of motorcycles. So I hit! Ha ha, just kidding, the main thing is that my application reasons should be distinctive, which I personally feel.

I'm sorry to let you listen to my long winded content. Now let's begin our evaluation of this Tuman.     

First, a slogan! "We are serious about playing computer games!"

In general, I may directly review from the perspective of unpacking -->appearance -->function -->summary, but I feel that the judge wants to know how to use it in practice. For the appearance, he has seen beautiful pictures on the official website, and we should give the judge a real feeling, so that he can decide whether it is worth buying according to the evaluation. OK， Then we will begin to experience the three generations of Turkmen.

The secret of the screen

First, let's popularize PPI:

PPI is the number of pixels per inch. Pixels per inch indicates the number of pixels per inch. The calculation method is very simple. The number of pixels in the diagonal direction (right triangle) is calculated from the number of pixels with long and high heels, and then the number of pixels in the diagonal direction is divided by the screen size to get the ppi. The formula is expressed as PPI=√ (X ^ 2+Y ^ 2)/Z (X: the number of pixels in the length; Y： Width pixels; Z： Screen size).

When the PPI of the mobile phone screen reaches a certain value, the human eye cannot distinguish the graininess. What is the value? According to Apple CEO Steve Jobs before 2010 (Steve Jobs) Introduction to retinal technology at the launch of iPhone 4: "When the thing you are holding is 10-12 inches (about 25-30 cm) away from you, as long as its resolution reaches the 'magic number' of 300 ppi (300 pixels per inch) or more, your retina will be unable to distinguish pixels." (The human eye can see the particle size Is it meaningless if the screen PPI exceeds this value? Even for products with resolution, it depends on its saturation , render degree··

The above content is extracted from Baidu Encyclopedia  

We one Generally speaking, the size of a mobile phone is the diagonal length of the screen, so the above formula needs to be applied when calculating PPI for a rectangular screen. Since the watch we are calculating is round, our calculation formula cannot be calculated according to the above company. The number of pixels given by the manufacturer is 400 * 400, as shown in the figure below. Since the screen size given by the manufacturer is 1.39 inches in diameter, we can not directly apply the above formula to calculate, but should directly use 400/1.39=288. That is, the PPI is 288. However, our watch uses an AMOLED screen, which uses a Pentile pixel array structure. Therefore, we have to give a 20% discount on LCD pixels at 288, and the final result is 230 PPI. Therefore, when you get this screen, compared with the current full HD LCD, its PPI is about 400, you feel very grainy. Specifically, I can see the grain feeling of pixels when taking macro photos with my mobile phone.

Now let's observe the difference between the two OLED screens under the microscope. One is Tuman's, and the other is Samsung's OLED screen used by Meizu MX5. The following two pictures have the same magnification of 200X. I calculated that there are 144 pixels in Tuman and 187 pixels in the MX5. At the same time, it can be found that the pixels of Tuman are smaller than those of the MX5, so its screen quality may be worse than that of the MX5.

Seeing this, the caretaker felt a little dizzy and thought: Can I still have it? Wait, let me continue to analyze:

What is the biggest pain point of smart watches at present? The battery life of Apple Watch, Motorcycle Watch, etc. is just one day. This screen plays a very important role in how to improve the battery life. AMOLED screen uses backlight to light up because it is different from LCD. The biggest advantage of AMOLED is its high contrast. When displaying pure black, pixels are not lit directly, which means no power consumption. Therefore, when we use a pure black dial, the pointer is bright, which is the most power saving. Then it is precisely because Thurman uses AMOLED screen to ensure that Thurman watch can last for two days. However, there is a difference for LCD. The backlight of LCD is always bright, so it doesn't matter what color the dial saves power.

Watchman, how about it? Are you feeling better? Well, let's continue to experience:

As for the perspective, we have heard that a battle between Zealer and Luo Laoluo is about the visual angle of the screen. Of course, the Tuman screen is not a dispute between Zealer and Lao Luo, but a slight blue phenomenon occurs at different angles. When you set a white dial, it is white when you observe it vertically, but when you tilt to a certain angle, it appears a blue color phenomenon. Since the effect cannot be photographed, the above picture is not shown, But let me remind you to see if you can tolerate it.

Astonishment of step counting

During the noon lunch break, we carried out the step counting test in the hot sun. This test found that this is BUG Ah, we have questions about why we should not swing our arms. I don't know if you have seen Huang Bo's pedometer tied to his arm in an episode of Extreme Challenge, and then there is no step count. But I found that the step count is quite accurate when we try to use a Tuman watch to count the steps without swinging our arms, because the sensor can detect a slight shake when walking, and use it to count the steps. You can see the table below. The accuracy rate is quite high!

If there is no arm swing, there must be arm swing. Everyone will be surprised after seeing it. How can it be like this? I can't help it. I counted it step by step against the scorching sun. If the arm is swung, the error begins to appear.

In order to test the accuracy of the asynchronous number three hundred Step five hundred Step eight hundred Step test, this result is more outrageous than the above data. three hundred During the step test, I found that it was a bit out of line, and I specially retested it again, and found that the results were even worse! But Thurman was in the last round eight hundred Step time counter attack!

In recent days, we have compared the steps of Xiaomi and Tuman. Both of them wear their arms to count the data gap throughout the day. The data is shown in the figure below. The overall steps of Tuman are too few.

Hoarse voice and rough vibration

First of all, let's talk about my voice judgment standard. I used a Lenovo 100 yuan machine before A820T The earpiece level of the MX5 The earpiece level is divided into two grades according to the high point. The external grade of the Tuman watch is equivalent to that of the Lenovo 100 yuan machine. The specific performance is that there will be broken sound when making a call. The sound is very rough, and there is no MX5 The earpiece is so clear and heavy. It seems that the manufacturer may be controlling the cost, but under the beautiful appearance, the sound of this product reveals the level of this product! Use it to make a phone call Low 。

Let's talk about the rough vibration. My judgment standard is still based on the vibration of the two mobile phones I have used. The vibration of the Tuman watch is not as good as that of my Lenovo mobile phone. It's just a simple and direct vibration without any exquisite feeling. Everyone may have used Xiaomi bracelet. The vibration of Xiaomi bracelet is still good, But the vibration of Tuman watch is not as good as that of Xiaomi bracelet!

Because the above two tests are subjective feelings, we also need to see the actual feelings of the official. My personal feeling is that it can be used, but the force is not high!

Sleep Monitoring - No      

The sensor of Toumann watch and gyroscope should be added with sleep detection function, but it is not found at present. I attach great importance to sleep monitoring, because I can know how my sleep quality was last night. It seems that my Xiaomi bracelet cannot be retired. PS : Does the manufacturer think that people take off their watches when they sleep at night?

Things about APP

Four interfaces

I can't help but complain again. I did my homework before and watched others' comments APP It was poorly done. In order to experience online in advance, it cost me fifty many MB The official application expression is downloaded from the traffic of UI Design, I just want to hehe! Icon design is very simple! It makes people feel weak! After entering the icon, I found that the function was also very weak. It seems that in order to display many functions, there are many small icons listed. In fact, these can be made into a menu. Show the key function graphs.

Complain that a point can be set on the software to automatically shut down, but it is not turned on !!! There is also the reason why the time area is so small and the font is so small when selecting time!

Xiaomi can make statistics and analysis of the two functions of step counting and sleep, but found expression APP The step counting function of is a chart display. And when today's data is less than yesterday's steps, yesterday's data will be displayed. How big is this BUG What about?

Still complaining: watch photographing function. When you click the photographing function on the watch, the phone will start the photographing program, which is Tumen's own photographing software BUG More. The viewfinder interface will lengthen and deform the object being photographed. At the same time, the focus is not very good. It's OK to play. It's far from the camera function on the phone. The photos taken at the same time do not know where to put them, which will be very crazy for Xiaobai.

Is there no bright spot? Of course, there is a function similar to WeChat's circle of friends, which contains all the circles of friends that express users' messages. There are many beautiful women. I don't know whether it is true. Who knows whether there is a pig behind the network, ha ha!

Summary: The software must be kept open when the watch is connected to the mobile phone. If the software is closed, the watch cannot be connected to the mobile phone. I hope Tuman can make some changes, because the Xiaomi bracelet can exit the APP, but it can still realize the call reminder. It means that there is a process for communication in the background, and it is unnecessary to keep the whole software open, which leads to the increased power consumption of the mobile phone.

Does the watchman feel sad when he sees here? In fact, I just listed the shortcomings I experienced for you first, and the dry goods below!

Watch system

Now let's talk about systems. The systems we wear now include Google's Android Wear, Samsung's Tizen, Apple's Watch OS, etc. What kind of system is a good system? First, since you have the attribute of a watch, you should work hard to make the theme of the watch dial exquisite, which is a highlight compared with traditional watches. Otherwise, what's the benefit of buying a smart watch? It's not easy to answer. Second, there are not many functions, but they should be refined. I don't want my watch to have the functions on my mobile phone, such as a calculator. Is it more likely to be used on my watch? I think I seldom use it because I carry my mobile phone with me. It is not necessary to click the small buttons on my watch in a small space. This function is redundant. There is also the navigation function. The navigation of the Tuman watch uses the voice and GPS of the mobile phone. Since there is a mobile phone, why do I have to navigate on the watch? And at present, I don't know whether to follow the car navigation or the pedestrian navigation in Tuman? Personally, this is not practical. Individuals still prefer watch to have NFC payment function, bus card swiping and other daily related functions.

I don't think it is necessary for the manufacturer to make a watch with various functions. When adding functions, do you want to make a survey and statistics to see if the corresponding functions are necessary. Now let's take a look at what functions Tuman has.

The top is the main function page of the Tuman watch On the disk interface, the above interface will appear when the fingers are drawn to the left, right, up and down. Six scenario interfaces will appear on the upward stroke, setting interface will appear on the right stroke, function interface will appear on the left stroke, and information interface will appear on the downward stroke.

First, we draw to the right to show the setting interface, as shown in the figure above. According to the lines I draw, you can know the corresponding menu level. My system here is version 12.1.A.013. I upgraded the system step by step from 010 to 013. When I upgraded version 013, I almost hung up the system. Suddenly, an interface similar to Android mobile phone dual clear, restart, and select menu appeared. I guess Tomos is really a self-developed system? Is it developed based on Android Wear? The above views are purely personal guesses.

The above is the specific display of the function interface drawn to the left. All the functions are on the top, and software cannot be installed. Then talk about the photographing function. After clicking the photographing function, the photographing interface will be launched on the mobile phone. The main program is the interface developed by Tuman. The bug of this interface is that the proportion of objects in the scene taking interface has been lengthened or compressed. At the same time, the focus effect of the photo is not good, and the photos taken are relatively blurred. The function is very good, but the effect is poor.

The above six scenarios are drawn up, including stock speculation, navigation, music, chat, sports, work, etc. What I usually use is the step counting and heart rate function. Forget the rest. Step counting is just a step counting, not counting. The heart rate is not intelligent. If it is intelligent, you can click him to measure it. Otherwise, he will not measure it. How can this watch talk about intelligence? I have complained about the navigation, but I don't want to talk about it.

Watch appearance

Watchman, are you still watching? I believe that a large part of them have not looked down any more, because after looking at the slot above, you may have made a judgment, but there is still a key point not to look! I have seen the appearance in other evaluations. Yes, so I won't list it for you here. Please see the official big picture to enjoy the beautiful picture. I just list the questions here.

I showed a picture of a smart watch in my friends' circle, and my friends sent congratulatory messages one after another, hmm, beautiful; I will go, Tesla brand; How much fuzz?; A motorcycle watch? wait. This reflects that Tumen's appearance is really good, very good. The objective master has doubted it and talked about so many shortcomings. Now he starts to praise it? No，No， The show officially started. My colleague came to visit my smart watch this morning and found a problem with the screen assembly. The screen of the watch was not properly assembled, which led to the black edge on the right side, but not on the left side. I don't know if there is a problem with my channel or everyone else. Let's try changing the dial to white. See the following figure for specific phenomenon:

The evaluation is a little different. My appearance evaluation is mainly to let you see the places you don't usually pay attention to, so I'll give you a special perspective: the following is the position where the watch strap is combined with the watch. You can see that the shell of the watch has a delicate frosting feeling. It feels very delicate on the touch. There is a circle of aperture around the dial, which still feels very designed. The surface of the watch strap is very textured. Here we begin to like.

There is a number 384401 on the back of the watch strap. It is said that this is the distance from the earth to the moon, which is also related to the Tomoon brand.

The back of the watch has the charging contact of the watch, the relevant information of the watch, and the heart rate test port. The back is regular.

The thickness of the watch is moderate and acceptable, and the weight is about the same as that of Seiko watch. Acceptable. A lot of design should be done to compress so many devices into such a small volume.

The above is the appearance view of the watch. The overall feeling is pretty good. The watch has its brightness adjusted to the highest level, so it can see the time clearly in the high sun.

The top is the charging base of the watch, and the position with a notch is the clamping point. The metal contacts can be pressed down. The workmanship of the base is good. The charging line is a general charging line, nothing special.

Endurance

Here comes the key point. You are most concerned about how long it can take. My usage scenario is like this: 25% of the power is consumed in 12 hours. During this period, about 7 hours are disconnected from the mobile phone, and more than 10 WeChat messages are sent and received by the connected device. The other time is to check the power consumption of the time to light up the screen. If you do not turn off the phone at night, the standby time should be 48 hours.

The other use case is that the connection is always maintained. After 36 hours of use, the remaining power is about 12%. Take a heartbeat or two.

TencentOS system

Recently, I saw that someone on the Internet has turned the third generation of Tuman into TencentOS system, so why not bother geeks like me? So I waited until I returned to Beijing from home to start the experience of machine brushing. There were still some twists and turns in the process of machine brushing. After two times of brushing, I found TencentOS's UI was particularly beautiful. However, because the background color of its setting interface was white, it looked particularly grainy, so compared with the Turkish system, the Turkish system was relatively intelligent in this regard, Because the OLED screen is not bright black, there is no sense of graininess at all.

Heart rate test, using Tencent OS to conduct heart rate test, found that the heart rate is more than that of Tuman. The heart rate of Tuman test is about 70, but Tencent test is about 80. I personally think that Tuman's is more credible, because Tuman knows more about its hardware, so the algorithm is more accurate.

advantage:

1. It means that you can connect with WeChat and QQ and reply to them, which is preferred by everyone because you can avoid frequently turning on your mobile phone.

2. The dial inside is beautiful and exquisite compared with the Tuman system.

3. The pattern UI is quite good, but the pattern on the white background is a bit more power consuming than that on the pure black background.

4. The application can be expanded, but the number is limited at present.

5. Speech recognition is great! The recognition rate is very high. As long as you say "Hi, Little Whale" on the dial interface, you can call out the voice assistant.

Disadvantages:

1. The power consumption is relatively high, but it's OK to use it for one day.

2. Remote photography cannot be used.

3. You cannot set the wrist lift function to turn off the screen, because Tencent OS will always turn on when the wrist does not move, and the screen will not turn off until you change the direction of the wrist. The mechanism is different from that of Tuman.

At present, I still use Tencent OS. After all, the dials in Tencent OS are beautiful, and they are all my favorite dishes. For the introduction of Tencent OS system pictures, please refer to In Watch T, which uses its system.

summary

This evaluation should end here. To sum up, I am not satisfied with the APP supporting this product, because there is no relevant health data statistics, and the functions are not very perfect. I feel that it is a simple increase in functions. For the screen, it should be made in China. Although the resolution is not high, it is absolutely energy-saving. Other smart watches in China may use the same manufacturer's screen, so it is good to get OLED screens here. The accuracy of step counting needs to be improved. There is no sleep statistics function. I feel a little sorry. The appearance of the watch is good, but the assembly accuracy still needs to be improved. But there are too few dial styles. The watch is certainly good compared with the general counterfeit manufacturers, but it is less refined than some enterprises. The impression of this watch on me is not very profound. There are no good highlights for me to recommend to my colleagues. If I pay for it personally, I feel I will regret it, because today's digital development, I feel that the workmanship and system should be very refined, but this model still has many regrets. It is hoped that manufacturers will continue to work hard to find their own highlights.
