From 2017 to 2020, the scale of China's adult smart watch market showed an upward trend year by year. With the gradual popularization of adult smart watches in China, combined with IDC's 2017-2018 market size data, after preliminary estimates, the size of China's adult smart watch market will reach 12.8 billion yuan in 2020.
At present, the characteristics of Chinese adult smart watch products are mainly concentrated in bluetooth synchronization mobile phone calls, send and receive text messages, monitor sleep, monitor heart rate, sedentary reminders, running steps, remote photography, music playback, video recording, compass and other functions. Designed for the modern urbanite. However, most categories of smart watches still need to rely on mobile phones to achieve functions, at present, only smart watches launched by Apple and Xiaomi on the market can exist independently of mobile phones.
Smart watches as wearable devices, smart phone notifications, exercise monitoring, fitness monitoring and other functions are one aspect of its development, on the other hand, more important is the application of scenarios. Although smart watches are still in the early stages of development, there is no doubt about the development direction of smart watches. On the one hand, it is necessary to meet the segmentation needs of consumers, on the other hand, in different scenarios, smart watches will play different roles.
Bluetooth is a personal lancing technology designed and marketed by the Bluetooth Technology Alliance for emerging applications in healthcare, sports and fitness, beacons, security, home entertainment, and more. Compared with classic Bluetooth, Bluetooth low energy technology is designed to maintain the same communication range while significantly reducing power consumption and cost, due to the relationship between low power consumption, so it is often used in a variety of common wearable devices and Internet of Things devices, the use of coin cell batteries can be executed for months to years, small size, low cost, and compatible with most of the existing mobile phones, tablets and computers.
Application of Bluetooth on smart watches
1. Application notifications
The application notification function in the development of the Bluetooth smart watch APP refers to the fact that the watch can remind calls, text messages and three-party application notifications. Prevent users from missing any important piece of information.
2. Exercise data and heart rate data
Motion data and heart rate data functions are features that every Bluetooth smart watch comes with. Users can record the number of steps walked, distance, heart rate, calorie burn and other information through this. After this information is recorded, it can be fed back to the phone via Bluetooth. Help users better understand their physical condition.
3. Weather management
Bluetooth smart watches can provide a change of weather function. Moreover, it will automatically locate the city and do a good job of early warning weather reminders.
4. Watch alarm clock
The watch alarm clock function means that when the user uses the smart watch, he can set multiple sets of alarm clocks on the APP, and when it comes to a specific time, the watch will vibrate. Users can turn off the alarm by simply touching the video with their hand.
5. Bluetooth positioning
Bluetooth real-time positioning. In addition, there is a one-key alarm function, which can play a guarantee role for users, especially minors.
