Wearable smart devices will be used as the carrier of sensors to realize more advanced and seamless interactions between humans, machines, and the cloud, and realize situational awareness, so that wearable smart devices have “smart”. The combination of wearable smart devices and artificial intelligence further supplements and extends the human perception ability. Contextual perception will be the next new trend in smart hardware technology. Soon many smart devices such as wearables will have certain “contextual perception” functions. The core of this application software must be the rise of artificial intelligence. The integration of artificial intelligence and smart devices such as wearables will bring a new technological experience.
