Feng, K., 2020. Interactive design for audio-visual language of marine animation: A simulation study. In: Gong, D.; Zhang, M., and Liu, R. (eds.), Advances in Coastal Research: Engineering, Industry, Economy, and Sustainable Development. Journal of Coastal Research, Special Issue No. 106, pp. 646–649. Coconut Creek (Florida), ISSN 0749-0208.The application of virtual simulation technology in the interactive design of an ocean animation audio-visual language provides a new interactive experience for ocean animation and users. Compared with the traditional design mode, virtual simulation technology can improve the satisfaction of users, improve the efficiency of the design scheme, interact with the audience's audio-visual language, and become part of the audio-visual language art of marine animation. This study first analyzes the interactive design points of an audio-visual language of marine animation, then introduces the advantages of the application of virtual simulation in the interactive design, and finally delivers an interactive design scheme of marine animation based on virtual technology.
