As a kind of intelligent wearable device, smart watches have been recognized by many people for their portability and rich application functions. However, most smart watches on the market are designed for ordinary adults, ignoring an important group - pregnant women. A woman needs more care when she is the happiest and most troubled in her life. However, due to the pressure of life, it has become a naked social problem that her relatives cannot accompany the pregnant women or excessive "care". It has become an urgent need to ease the "pregnant women problem" with wearable devices.

Packaging and accessories
▲ The package is not a square box commonly used for wristwatches, but a "chopstick style" strip package.
▲ The LOGO of "LISA" is printed on the bottom of the package, followed by the four functional attributes of LISA watches.
▲ The back of the box is the QR code used to download the client. The smart devices on the market are both hard and soft, and LISA has not escaped this mode.
▲ Pull out the blue "binding" on the outer layer, and the inside is a watch box similar to leather paper.
▲ The bottom is the barcode of product ID.
▲ The upper and lower packaging similar to that of iPhone is adopted. Due to the small depth of the watch box, there is no "difficult to open" phenomenon of similar packaging in the market.
▲ The color matching is mainly white and blue. Although the colors are different, the lines are the same.
▲ When opening the package, I saw that it was not a LISA watch. A manual similar to the package occupied the whole view.
▲ Unexpectedly, a two-dimensional code of the manual is hidden inside the upper cover, and the electronic version of the manual can be easily scanned. Although it is only some micro innovation, the details still leave a good impression on the user.
▲ The manual adopts cartoon presentation, with pictures as the main form, which undoubtedly reduces the pressure on Xiaobai users.
▲ Turn to the back, the international English description will be on the paper, and a bilingual instruction will instantly promote the product to the international level.
▲ Under the instructions is today's leading role - LISA pregnancy table.
▲ Family photo: The blue "binding", packaging box and instructions are quite simple, without any accessories, and even deeply doubt whether this is an intelligent device.
Exterior body
▲ At first glance, it really looks like a traditional female watch. But the combination of metal and leather has really improved the quality of the product.
▲ In order to better adapt to female users, the wrist strap has been thinned to make the whole body more compact.
▲ The dial glass will have a delicate reflective effect under the side light, but it is really easy to stain fingerprints. Fortunately, the blue background makes the stained fingerprints not obvious.
▲ The glass and the stainless steel frame of the dial are closely connected, and the glass and the metal frame are basically in the same plane, which shows LISA's attention to detail processing.
▲ The whole dial is extremely simple. There is only one brand LOGO in the middle, and 12 LED lights are distributed around the dial, but they are invisible when off.
▲ The way to display time is to turn on the light. After being awakened, the light for hours will always be on, and the light for minutes will flash. Since there are only 12 lights, the accuracy can only reach 5 minutes.
▲ The product information symbol is in the middle of the back, and the LISA logo of the watch is on the top. Different from the smart watches on the market, there is not a screw on the whole back, but the thread fastening method of the traditional watch is used. The back cover is polished and its mirror effect is very dazzling.
▲ The workmanship of the dial is quite excellent, and it is quite competitive. Officially, its surface is called sapphire glass, which can attract people's attention just because of its name.
▲ There are traces of chamfering and polishing at the junction with the watch band, and the full width dial is beautiful.
▲ There is chamfering treatment similar to iPhone 5s frame at the top and bottom of the side, while polishing treatment is added to the surface mask.
▲ The buckle of the watch belt and the watch body are made of the same material, both of which are fine steel.
▲ Not only the body is excellent, but also the wrist strap is very excellent. It is made of cow leather and feels good.
▲ It can be seen from the hole on the other side of the belt that the integrated wrist strap is made of sufficient materials. The consequence is that the whole wrist strap is stiff and reduces the user experience.
Operating principle
LISA completes all work through built-in LED lights, motion sensors (accelerometers) and vibrators.
The 12 LED lights display the time in the way that the hour hand is always on and the minute hand is flashing. In order to save power, the time display will be performed only when the action wakes up.
The motion sensor has been recording the displacement and posture in the background, and counting the calories consumed by the user through the algorithm.
Count the number of manual inputs to measure fetal movement.
In order to give better care to pregnant women, the watch body surrounded by three sides of metal is designed to greatly isolate the Bluetooth signal in the outward direction.
Software
In this era of intelligent hardware for mobile phone interaction, the APP corresponding to each hardware is essential, and the LISA pregnancy table itself can only do the interaction work of shaking and lighting up. In addition to looking at the time, all functions are completed through the app.
▲ The software follows a lightweight design route, and the entire installation package is only 5M.
▲ The first near software is a guided operation, which reduces the learning cost of users.
▲ The first time you open an application, you need to register. Only Baidu accounts are supported, while popular third-party authorized logins such as QQ and Sina Weibo are blocked, which undoubtedly adds a burden to users.
▲ The application will automatically request to open Bluetooth, abandoning the traditional Bluetooth search connection, but entering a specific connection method through the product ID. In fact, this connection method is not new, and has been used in smart sockets for a long time. Although the connection mode of product ID input increases the security of the product, it also increases the operating burden of users. It can be seen that LISA has made some trade-offs in security.
▲ The main interface is clear, and the two main functions of the pregnancy table (pregnancy+shaping) are at a glance.
pregnancy
▲ Before using the "Pregnancy" function normally, you need to set your own pregnancy and childbirth period. During pregnancy, there are two options: "exercise" and "fetal movement".
Sports:
▲ Next is a series of guiding operations (only in the first use), happy strokes!
▲ After completing the guidance steps, you can view the motion data, and you can view the historical data by scrolling down.
▲ Daily exercise goals can be set at the bottom of the data, but it is worth noting that the exercise goals are set once a week in a week.
the fetal movement:
▲ It is also a series of guidance operations (only in the first use), let's enjoy the stroke! Each fetal movement needs to be recorded manually. Long press the dial to complete a record.
▲ View the fetal movement data, and similarly underline to view the design of historical data.
▲ The sharing function is better. As a prospective mother, the happiest thing should be the baby in her belly.
▲ In the process of use, the author also found a micro innovation that supports double clicking the full screen display of the data interface and one click sharing.
Shaping
▲ Guide the operation.
▲ View the motion data, and also scroll down to view the design of historical data.
▲ Daily exercise goals can be set at the bottom of the data, but it is worth noting that the exercise goals are set once a week in a week.
The whole shaping function is very weak. I didn't find any difference between it and the motor function during pregnancy, but can I set a larger target?
▲ Simple setting interface.
Experience
The functions of LISA are nothing more than to watch time, exercise calorie consumption and fetal movement records.
As a smart watch, the first thing to investigate is the time display. LISA's time shows that it is better than ordinary bracelets, but it still lags behind conventional watches. Unfortunately, the watch only supports double click wake-up screen.
However, the biggest problem is the design of the flashing pointer. After the hour hand is displayed, you have to wait nearly 1 second to see the minute hand, which directly causes the action of looking at the time to take 2-3 seconds, and it is impossible to "glance" at the time. In addition, the accuracy of 5 minutes is not a small problem.
However, the step counting function can only show calorie consumption, which is very different from similar products on the market. LISA focuses on the safety of pregnant women and fetal movement records, so the author will not repeat the exercise.
summary
According to the conventional definition of a smart watch, it should be able to interact directly with users, and even display short messages or reminders If this algorithm is followed, LISA is not a smart watch, but a traditional watch with motion detection or an immature bracelet.
The time display of the LISA pregnancy watch is similar to that of the inWatch π watch, but the wake-up mode is inferior, and the time precision is also somewhat different from that of the traditional watch.
As an intelligent product focusing on pregnant women, its radiation hazard is more important. LISA adopts a three sided metal design, which reduces radiation to a certain extent, but the actual effect needs professional instrument detection. But the pregnancy table series created by LISA has expanded the group of intelligent hardware, which is very commendable.
However, different people have different opinions on its cost performance. Its official price is 799 yuan. Whether it is worth buying depends on everyone's needs.
