3D animation and human-computer interaction of virtual characters in sustainable ecosystem

With the increasing popularity of artificial intelligence-related technologies, the emergence of various new technologies has brought people more convenient living and entertainment equipment. Nowadays, computer animation has penetrated into all aspects of people's lives, computer animation has become a huge industry, and there is a trend of further growth. The game industry has become an important pole of the computer animation industry and has been developing like fire for many years. However, research on 3D animation production and human-computer interaction has remained at the theoretical level. In this paper, we scientifically analyse and conduct high-dimensional research on 3D animation production and human-computer interaction from the level of artificial intelligence virtual characters. The research results show that users can adjust the path curve of AI characters, which helps to articulate movements in 3D animation production; the average classification accuracy of virtual EEG signals based on EEG and EMG for gesture recognition and interaction is 65.3%, which provides a basis for improving research on 3D animation production and human-computer interaction.
