Interactive Knowledge Visualization Based on IoT and Augmented Reality

Abstract

In order to solve the integration value of information technology and education, it is mainly reflected in the container for storing and disseminating information, the problem is that learners lack the proper self-learning ability, and the author proposes an interactive knowledge visualization system based on the Internet of Things and augmented reality technology. According to the applicable characteristics of augmented reality technology applied to IoT data presentation and interaction, the method can analyze and describe its application possibility. In the design of interactive electronic technology computer-aided teaching system based on NET platform, the system hardware structure consists of user interface layer, business selection layer, and data management layer. Users such as teachers and students enter their identity information at the user interface layer to log in to the system and enter the business selection layer and click the corresponding program according to their application requirements, the service selection layer transmits the user's selection instruction to the data management layer, and the data management layer selects the corresponding resources according to the user's needs and feeds it back to the user. The interaction of the system is mainly reflected in interactive teaching and information interaction, and interactive teaching is reflected in the online teaching of teachers and students. Information interaction is embodied in the information transmission of the system information interaction model. Experimental results show that after applying the system, the number of students with high self-efficacy increased from 11 to 21 and the proportion increased from 21.4% to 34.8%. The system designed by the author has strong antipressure ability, can respond to the application instructions of a large number of users in real time, and has a good interactive teaching effect, which improves the self-efficacy of students.
