Abstract: With the rapid advancement of intelligent level, the concept of user experience and interaction design is gradually recognized by people, and smart watches become an important part of user experience. Due to the short appearance of smartwatches, a complete system has not been formed, in order to improve the sense of user experience of smartwatches. This design is based on STM32 microcontroller design of a smartwatch, through the GPS locator to obtain the specific value of latitude and longitude of the watch user, can be reported the location information, at the same time, the recipient can send “GET” to obtain the latitude and longitude, when sending information, LED light flashing, automatic positioning and timely reporting function; The lighting can be switched on and off by pressing the button to realize manual control of the lighting function; Display time, longitude and latitude equivalent through OLED display; Through the MCU internal RTC time acquisition, but also through the button for time correction. This design of smart watch is mainly intelligent, multi-function for the development direction, by changing the function of smart watch to meet the needs of the majority of users, to provide users with good use experience.
