With the rapid development of e-learning, more and more learners use electronic devices to learn English. The traditional way of learning is often lack of interest and interaction, therefore, this paper discusses how to improve the effect of English learning through the application of immersive human–computer interaction and digital entertainment new media. Research on the selection of appropriate virtual reality, augmented reality or game platforms, design interactive content and scenes according to learning objectives, and use elements such as virtual scenes, virtual characters and audio-visual effects to improve learners’ immersion. Through careful design and production, learners can be presented with a lively, interesting and challenging learning environment to stimulate their interest and enthusiasm in learning. Develop interactive learning tools and applications that enable learners to interact with virtual environments or games, make appropriate adjustments and feedback based on learner feedback and behavior, and provide personalized learning support and guidance. Through the collection of learner feedback and behavioral data, combined with the evaluation indicators of learning outcomes, the immersive learning environment and content can be evaluated and improved and optimized according to the evaluation results, so as to further enhance learners’ learning motivation and learning outcomes.
