Originally, interpersonal communication was face-to-face, fully immersive, with communication methods including sound, text, expressions, actions, etc., and such communication was immediate and interactive. With the advent of digital communication, as spatial distances increased, ways of communication also began to change. In the era of single media, communication was limited to one of the following: text, graphics, sound, etc. In the multimedia era, communication methods became more diverse, incorporating text, graphics, sound and video, yet people were still constrained. In the era of interactive multimedia, all-round, real-time interaction has been finally realized and widely acclaimed, which is precisely the earliest form of human communication.

Multimedia is ultimately a matter of experience, however, one should never forget that there is always an inexplicable and irresistible magic to new things. However, people are naturally inclined to prefer the new to the old, so content is always an innovative element that should not be overlooked. The content of multimedia innovation is mainly related to images and sound effects.
