At the same time, the application of new materials and new technologies has brought about great changes in creation, which has also put forward new requirements for modern product design. Digital media art is spreading a more humanized design concept, changing the lifestyle of all classes and blurring the boundaries of traditional design. Digital media art can be said to have changed people's cognition of design. No matter from design scheme conception to software rendering, or to the final virtual dynamic display, it has proved that digital media art has penetrated into every link of product design. Design has shifted from a single static dimension to a multi-dimensional interactive dimension, and product design has been reborn due to the development of new media art, thus promoting social innovation and social change.
