Can gender categorization influence the perception of animated virtual humans?

TL;DR

This study investigates how gender cues in animated virtual humans influence perception and emotional response, revealing that simple gender information like a name can significantly alter viewer perception.

Contribution

It demonstrates that gender attribution in virtual humans affects perception and emotional response, replicating real-world findings through computer graphics.

Findings

Perception varies with gender cues in virtual humans.

Name alone can influence emotional responses.

Results align with previous studies on real babies.

Abstract

Animations have become increasingly realistic with the evolution of Computer Graphics (CG). In particular, human models and behaviors were represented through animated virtual humans, sometimes with a high level of realism. In particular, gender is a characteristic that is related to human identification, so that virtual humans assigned to a specific gender have, in general, stereotyped representations through movements, clothes, hair and colors, in order to be understood by users as desired by designers. An important area of study is finding out whether participants' perceptions change depending on how a virtual human is visually presented. Findings in this area can help the industry to guide the modeling and animation of virtual humans to deliver the expected impact to the audience. In this paper, we reproduce, through CG, a perceptual study that aims to assess gender bias in relation to a simulated baby. In the original study, two groups of people watched the same video of a baby reacting to the same stimuli, but one group was told the baby was female and the other group was told the same baby was male, producing different perceptions. The results of our study with virtual babies were similar to the findings with real babies. First, it shows that people's emotional response change depending on the character gender attribute, in this case the only difference was the baby's name. Our research indicates that by just informing the name of a virtual human can be enough to create a gender perception that impact the participant emotional answer.
