Design of an interactive platform for online audio-visual teaching of English based on augmented reality technology

In order to overcome the problems of high teaching cost, low efficiency of implementation and low utilisation of teaching resources, this paper proposes an interactive platform of English audio-visual online teaching based on augmented reality technology. According to the characteristics of the current online audio-visual teaching class of English, the user needs are analysed. The platform hardware is divided into web server, teacher client and touch integrator based on MVC framework, the connection between teachers and students is realised through hardware design. The augmented reality technology is applied to the interactive application of online audio-visual teaching of English. Through AR technology, an educational background is created, classroom teaching is strengthened, and makes the task cooperation between teachers and students smoother. The experimental results show that the platform can reduce the teaching cost and improve the efficiency of the system and the utilisation of teaching resources.
