The development of digital media art in China has spanned over 20 years. From desktop design to virtual imaging, digital media art has gradually transcended the "screen" and entered the virtual space and digital era, undergoing tremendous changes. The application fields of digital media art have shifted from initial areas such as graphic design and film and television special effects to multiple fields including exhibition design, healthcare, military, and geography. Digital media art not only offers us novel audio-visual experiences but also provides various conveniences in our daily lives. As the digital era enters a new stage, human activities have become closely intertwined with digital media. The public can now express, create, and communicate freely and conveniently anytime and anywhere through digital media. Digital media art, relying on digital media technology to present creativity artistically, has a profound and crucial impact on the growth and expansion of the cultural and creative industry. The economic benefits brought by the cultural and creative industry have attracted worldwide attention, leading many countries to introduce relevant supportive policies to promote the rapid development of the digital media art industry and sector. This book conducts research under this background, analyzing the value orientation of digital media art in the era of self-media, summarizing the aesthetic development of digital media art and the integrated application of artificial intelligence, and exploring the design methods of immersive scenarios in digital media art as well as the application strategies of digital media art in immersive theater.
