Research on Interactive Avatars
I have used avatars during live and prerecorded conversations to examine personality perception, influence, and preference in neurotypical adults and children with and without autism.
Conversing with Children: Cartoon and Video People Elicit Similar Conversational Behaviors
Children treat cartoons and real people similarly during videoconferencing interactions.

Assessing the Effects of Avatar Characteristics on Interactions with Adults
Increased facial expression positively correlated with perceived extroversion but decreased realism and naturalness. Additionally, modifying facial motion affects persuasiveness.

Facial motion magnitude was positively correlated with emotional expressiveness but negatively correlated with naturalness.

Are Children with Autism More Responsive To Animated Characters?
Children with autism do not prefer to interact with a cartoon over a human therapist.

Perceptual Effects of Damped and Exaggerated Facial Motion in Animated Characters
Realistic-looking characters benefited from increased motion whereas cartoon characters benefitted from damped motion. The amount of facial motion correlated with perceptions of extraversion.
