Track Your Emotional Perception of 3-D Virtual Talking Head in Human-computer Interaction

摘要

To investigate how emotions are identified from the avatar character in the natural scene during human-computer interaction. In current paper, a novel 3-D virtual talking head system with dynamic emotional facial expression for applying to human-robot communication was developed. Furthermore, eye tracking experiment and subjective evaluation experiment were utilized to explore the emotional perception of the 3-D virtual talking head. The results showed that there was no significant difference of observation mode between audio-visual animation of 3-D virtual talking head videos (AV3D) and audio-visual human face videos (AVHF). Besides, the recognition accuracy of HF was higher than 3D and almost all the accuracy of emotions had been improved when adding audio to videos. Finally, the results demonstrated that happiness was identified the best whether watching 3-D virtual talking head videos (3D) or human face videos (HF). These results implied that the 3-D talking head has potentially been as a suitable natural communication form in human-computer interaction.
