The emergence of smart devices such as smartphones and smart watches has made people's lives more convenient. In order to adapt to people's usage habits and application scenarios, smart devices also need to make better solutions in product design and interaction design to achieve a more comfortable user experience. So, how should designers design tools and devices such as smart watches?
I. Introduction
1. What is IOT
First of all, let's first popularize the concept of IOT.
The Internet of Things (IoT)/Smart Connected Device, or Internet of Everything, represents that everything in the world can interact and share through information technology.
This concept was first proposed by the MIT Auto-ID Center in 1999, and then on November 17, 2005, at the World Summit on the Information Society (WSIS) held in Tunis, the International Telecommunication Union (ITU) released the "ITU Internet Report 2005: Internet of Things", officially proposing the concept of "Internet of Things".
In recent years, with the concept of "smart earth", the Internet of Things has continued to appear in all walks of life, and the Internet of Things technology has gradually begun to improve people's quality of life in intelligent life, and has gradually evolved into an important part that cannot be lacked in people's daily lives.
2. Classification of IOT
As the name suggests, the Internet of Things is a network of things, but its core and foundation is still the Internet.
Through the power of the Internet, users can exchange and communicate information between any item on the client, so IOT can be applied to smart home systems, military engineering, automotive, hospital logistics, modern agriculture and other fields.
For the IOT that our domestic people are currently in contact with, it is the most widely used in the field of smart wear and smart home, the application quality is relatively high, and people's recognition of smart home is also relatively high.
Think about how many people will now rely on smart wearable devices to meet health monitoring, payment, control devices and other functions.
Why can the field of smart wearables achieve relatively rapid development?
Adapt to the new needs of people for experience in the new era;
Rely on the promotion of small smart products.
In other words, it is precisely because of the intelligence of the product that IOT technology can use wireless network technology to achieve its own monitoring and control of smart devices, and adapt to the personalized needs of consumers, providing consumers with personalized application solutions.
Today, when everyone has mobile phones, computers and other devices, IOT can link intelligent devices with smart wearable devices to provide users with conditions for remote control.
For example, smart watches, users can complete the control of related devices at work or on the way home, and can also monitor heart rate health through watches.
Second, the background and status quo of smart watches under IOT
1. The development status of smart watches
When it comes to the development of IOT, our smartwatches are indispensable.
Smart watches belong to wearable smart devices, wearable smart devices This idea has appeared in the early years, Google, I/M companies have tried to do it, but due to insufficient conditions at that time, the degree of "intelligence" is far from enough.
In 2010, Apple installed a professional strap on the iPod Nano6, enabling the beginnings of modern smartwatches.
Since then, with the rapid development of science and technology, what unlimited communications, big data, cloud computing and other functions have become more and more mature, and smart watches have also been pushed to the peak.
First of all, Samsung, the leader of the Android camp, launched 5 smart watch products in one year, followed by Pebble, which raised more than $10 million in the overseas crowdfunding market, which is also "a stone to stir up thousands of waves", and its first version of the product created 300,000 sales.
Subsequently, domestic millet, OPPO and other Internet manufacturers also joined in, so that the smart watch market presented a scene of a hundred flowers, think about it is terrifying
Let's talk about apple and google, two giants that were particularly mature at that time.
Google released an intelligent "virtual reality to expand the eyes" in 2012, which can control directions, videos, take photos and surf the Internet through voice.
Apple's Apple Watch has adopted high-tech technology.
Its screen uses olED screen, support wireless charging, screen support multi-point control, and self-developed S1 chip, its back is covered with many sensors.
Moreover, the interaction mode of Apple Watch breaks through the original interactive operations such as clicking and sliding, and adds a new press operation, which can identify the pressure level and allow developers to create better interaction methods.

Today, many giants have begun to enter the intelligent device, and have begun to develop from the original accessory class and induction wearable smart device to a new platform device, becoming a complete ecosystem.
2. Classification of smart watches
Up to now, there have been many changes in the development process of smart watches. We divide it into two types:
Platform level: the vast majority of them can be completed and calculated independently, belonging to relatively independent individuals;
Attachment class: This may require mobile phones, computers and other devices to implement.
1) Advantages of "platform" smart watches
Data analysis and processing power
The smartwatch we used before is a platform-level smart wearable device, which itself has a certain amount of data analysis and processing power.
People can experience a variety of mobile Internet applications and services through the touch screen of smart watches.
For example, the S1 chip on the Apple Watch, which is highly integrated and powerful, is very special compared to a single smartwatch.
Interactive mode
Platform-level smart watches also have certain interaction methods, such as images, touch, voice and other interactive means, which can interact with users.
For example, Apple Watch also added a multi-dimensional interaction method, that is, a press-type interaction, called Force Touch technology. In general, you can call out the Context Menu.
However, due to the weak discoverability of the Force Touch gesture, it has been replaced by a long press.
Host information
Platform-level smart watches can also carry a lot of application software, can download, install, uninstall and other operations, which makes it possible to complete a series of operations such as TEXT messages, phone calls, music, health reminders and so on. And platform products can not only meet the needs of users, but also create demand, and demand can be slowly cultivated through network effects.
For example, douyin, if there is only a single, small number of users will not actually have an effect, but when everyone is using it and relying on it, then more needs and possibilities can be mined through users.
2) "Dependent" smart watches
Data collection capabilities
Dependent watches generally need to be used with other devices, generally mobile phones, which are responsible for collecting user data.
For example, the Xiaomi bracelet provides the calculation of the distance walked and calorie consumption, and the internal sensor can also provide functions such as sleep monitoring, which is to upload data to the server and then synchronize it to the APP. So the core of this type of product lies in the strong data collection ability.
Low cost
Such products remove a lot of professional technology, only need to invest some cost in the sensor, through the shape, brand advantages can obtain a certain number of users. This is very convenient for the new user expansion of smart watches, on the one hand, to break into the mass market, expand the scale and user recognition of smart watches, on the other hand, it can also cultivate loyal users.
Diverse shapes
Due to its low threshold characteristics, it is very easy to be copied by small and medium-sized factories, and the price is still cheap. However, the functions they provide are all the same, and the difference is the styling.
Third, the application of user experience in smart watches
1. Explore smartwatches with four interactive properties
As a "skin-friendly" device, smart watches pay more attention to user experience, and we analyze them from the four attributes of behavior, image, voice, and data.
1) Behavior
Behavior is easy to understand is the behavior operation after our autonomous conscious operation.
There is behavioral interaction between people and people, and there are also behavioral attributes between people and products.
The product will rely on the feedback after the user's operation to determine the user's experience, with the in-depth exploration of the product, the product will accumulate more behavioral attributes of the user, and provide users with a stronger sense of user and operation experience.
For example, the Apple Watch has the function of pulse monitoring and activity monitoring, which detects the heart rate through the smart sensor behind the watch and feeds it back to the watch in real time. Similarly, if you sit too long or eat too much and your blood pressure is high, the watch will give you the appropriate tips and advice.

For example, after the Xiaomi bracelet is connected to the mobile phone, the user's phone rings after the mobile phone vibrates to perceive, and the target number of steps can be set every day, when a certain value is reached, the indicator light will light up.
This way that people are products and products are people can pull up the characteristics of humanity, interaction, and emotion in user experience design.

2) Image
Images are the main output method of the watch and the basis for user interaction.
Because of some limitations, smart watches are smaller and more limited in space than other smart products.
The smaller screen size makes the screen only display limited information, in order to maximize the user experience on the smaller screen, you need to consider the design elements of the interface and related influencing factors in the design process, so that the APP interface is clear at a glance.
3) Voice
Voice interaction is a wide range of interaction methods, and voice is the main communication method between people, which can narrow the distance between people and products.
For example, Apple's Siri and Xiaomi's Xiaoai students have conducted in-depth research in the field of voice interaction.
Apple's Apple Watch has the Siri function, which can be woken up and operated by voice in the sleep state, because the watch is a "skin-friendly" device, and the interactive operation of the watch is more unique, making the voice a faster means of operation than other operations such as finger operation and external devices.

4) Data
The value of data to a design is immeasurable.
Now the smart watches on the market are more tools for collecting data, through the collection and summary of human body data, continuously provide users with new data.
For example, the Xiaomi bracelet can detect the user's health and upload it to the cloud, and the user can see whether he has recently eaten fat or lacked exercise through data feedback.
The binding of WeChat and bracelet allows users to understand the movement of family and friends in real time, and the bracelet can also detect the user's sleep.
Therefore, the establishment of a large database has unlimited possibilities for the future of medical care, education and other fields.
2. Interactive interface analysis of the two platform systems
At present, the two major systems that everyone knows most are not the Apple camp and the Android camp, which are equipped with Android Wear system and Watch OS system respectively.
Because smart watches also use these two major system designs, the starting point and principle of their design are relatively similar, which are composed of simple interaction methods and clear layouts.
Although watches are different from mobile phones and do not have as complex function modules, they all have the ability to receive notifications and push, simple interactions, and accurate reading performance.
1) Watch OS platform interactive interface design principles
For individuals
Apple defines the Apple Watch as a "personal" device. First of all, the smart watch as a "skin-friendly" device, convenient to become the user to receive information at the entrance, the action of raising the hand can obtain most of the information flow, followed by simple reply, reply and other operations.
Hardware and software integration
Apple attaches great importance to the unity of its own ecological products, and the experience of computers, mobile phones, iPads and other devices is basically the same.
Square style, retina screen, etc. are all designed to work seamlessly with Watch OS.
The developer manual said that when developing watch OS APP, try to use a black background, and its UI should be seamlessly integrated with the edge of the screen, so as to give users a seamless visual experience.
Interaction is lightweight
The interaction on the Apple Watch is simple and fast, unlike the complex operation methods such as mobile phones and computers. Lift your phone to see the latest information you've received, face unlock while wearing a mask, and turn off the screen when you lower your wrist.
2) Android Wear interactive interface design principles
Customizable
Android Wear can automatically identify the needs of users, and accurately locate users' preferences and customize them through data feedback.
The UI focuses more on the way to browse the big picture, which increases the fault tolerance rate of the operation and the speed of the operation.
"Let the user experience meticulous service" is the original intention of the Android watch design, and you can set up a push message service by yourself, which can effectively avoid the situation that too many messages lead to boredom.
Search and suggestions
Google's powerful search capabilities are integrated into Android Wear, users can search anytime, anywhere, and Google services can learn from users' usage habits and provide suggestions.
Automatic recognition
Android Wear can judge and push relevant content to the other party by sensing the time, location, and psychological state of user feedback.
3. UI interface analysis of the two major platform systems
After talking about the interaction layer, let's talk about the UI layer.
1) Material Design Design Guidelines
The system design style of Android watches is equipped with the design style of Material Design on Android 5.0 systems.
Material is the metaphor
Among MD's design guidelines, the most distinctive is the interpretation of metaphors.
Wide range of cards, multi-level shadow systems, eye-catching transition animations, these are MD's most recognizable expressions.
