[0002] A smart classroom is an intelligent teaching environment built upon modern information technologies (such as the Internet of Things, artificial intelligence, big data, and cloud computing). It aims to optimize teaching processes, enhance the learning experience, and achieve efficient management of educational resources and personalized instruction through technological means. Visual communication devices in a smart classroom refer to equipment that transmits teaching information through optical and electronic technologies, aiming to improve teaching effectiveness and interactive experiences. The main types include interactive display devices, information display and announcement devices, auxiliary visual devices, and environmental control devices. Electronic class signs are used to display class information, timetables, weather forecasts, etc., and support remote network updates, synchronizing with the school's management system.
