In order to solve the problems of low extraction speed, poor flexibility and low expression effect of new media interactive elements, artificial intelligence-driven design and realization of interactive digital art works are proposed. This paper analyzes the main expression scenarios of new media interactive art, i.e., user information conveying scenarios, new media interactive art pushing scenarios, interactive art promotion scenarios and personal service scenarios, provides scenario application basis for interactive expression, calculates spatial complexity, spatial complexity and resource complexity, and carries out the interactive design from the three aspects of visual elements, multimedia elements and human-computer interactive elements according to the results of the complexity calculation. According to the result of complexity calculation, the interaction design is carried out from three aspects of visual elements, multimedia elements and human-computer interaction elements, the topology is integrated after the interaction is realized, and the interactive art of multimedia elements is expressed on the display and control of the new media network topology. The experimental results show that the speed of extracting interactive elements of the new media interactive art expression method based on artificial intelligence technology is increased by 30%, and the flexibility is stronger.
