摘要：In recent years, virtual humanoid images such as Yoo Night Hee and Tian Yu have started to appear in large numbers. However, it has been observed that the general public pays more attention to virtual human images in their initial stages, after which their attention decreases. However, the popularity of such avatars is still high. The questions studied in this paper include: Do fans develop emotional stickiness to avatars? What factors drive fans to be emotionally attached to avatars? This study uses questionnaire survey method to carry out the research, and found that: the stronger the degree of simulation of virtual idols, the stronger the emotional stickiness of fans. The stronger the fans' identification with the avatars, the stronger the emotional stickiness. And the stronger the interaction between fans and virtual characters, the stronger the emotional stickiness.
