Design and Application of Virtual Avatar Framework Based on E-commerce Live Streaming

With the rapid development of live streaming services, enterprises, as well as online celebrities, are increasingly in demand for 24-hour live streaming support to engage a broader audience. However, no person can broadcast twenty-four hours a day for a long period of time. Therefore, the virtual avatar is proposed to replace the real avatar for streaming. Based on the new thinking on the use scene of digital human, this paper designs a virtual avatar called Miebo. Through a series of experiments, it is found that the parameters that can produce the most effect on Miebo's emotion of “Sadness”, “Happiness”, “Surprise” and “Anger” is “Upset”, “Grin mouth”, “Open mouth big” and “Eyes closed” respectively, and the presentation results of Miebo's facial expression are optimized according to the experimental analysis. We also present a set of highly feasible virtual avatar application schemes and develop a special platform for virtual avatar design called “Virtualfull”, which allows ordinary users could create their own virtual avatars.
