The increase of globalization level puts forward higher requirements for cross-cultural language interaction ability. Based on the hierarchical teaching method, this paper designs a virtual simulation experimental platform with three layers: basic experiment, comprehensive application and research and development, and realizes the adaptation of educational resources according to the ability. Using the histogram equalization method and Adaboost algorithm, we optimize the gesture recognition to improve the real-time feedback effect of the platform in crosscultural interaction. Relying on Raspberry Pi hardware and Scratch graphical programming and other technologies, build an intelligent language teaching system in the platform to visualize language feedback. The application value of the virtual simulation platform is judged through language education practice. The results show that the resource occupation of the virtual simulation platform system is basically not more than 100% and occupies less resources. After utilizing the platform for assisted teaching experiments, the classroom interaction activity, students’ crosscultural language communication ability, and the level of operating skills of the experimental platform were increased to the highest 96.01%, 72.23%, and 60%, respectively. The average score of the evaluation of the platform’s functional diversity and the effectiveness of feedback and communication was over 4.5 at the highest.
