Cross-Cultural Research on the Construction of Digital Media Takes Virtual Idol Landscape as an Example

Research background: In the context of digital media globalization, virtual idols, as a new type of media with its own relationship, is an extension of human strong relationship. Virtual idols add relationship attributes to content, making it easier for some audiences to be noticed and recognized, and they are more influential. With the influence of virtual idols or virtual assistants, content and products can touch the target audience group (fans or students) more quickly. It is not only an important medium for students to define and present themselves, but also an important way for students to project self-image, obtain identity marks and create self-value. In the era of digital virtual idol technology, virtual idols carry a new algorithm based on relationship logic, which can help the communicator find the target audience more quickly (Atkinson, R. K. 2002). At the same time, the target audience is also more willing to accept the content related to the favorite virtual idols because of the relationship between them and their idols. In addition, in online education activities all over the world, teaching agents can be designed as human or non-human roles. Human roles can be visualized as videos of human tutors, as well as roles which are calculated and generated, and can effectively avoid the problem of students' distraction in learning. The latter can be visualized as static or animated images, so that virtual idols have full opportunities to enter the field of digital education. With the help of virtual imaging, virtual idols break the boundary between anime and three-dimensional (Clark & Mayer, 2002), and interact with fans, students and other groups with more realistic individual images.
