Highly realistic virtual avatars are perceived as more attractive and trustworthy, while moderately realistic avatars can evoke feelings of eeriness. This user-centred design research insight is drawn from a 2025 study published in Frontiers in Psychology. Using Network meta-analysis (nma) with 2343 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing virtual avatars, carefully consider the desired user perception and choose a level of realism that aligns with those goals, avoiding moderate realism that might cause unease.

Key Findings
- 01High VAAR is associated with increased perceived attractiveness.
- 02High VAAR is associated with increased perceived trustworthiness.
- 03Medium VAAR elicits the strongest feelings of eeriness.
Application
Design takeaway
When designing virtual avatars, carefully consider the desired user perception and choose a level of realism that aligns with those goals, avoiding moderate realism that might cause unease.
How to apply
When developing virtual characters for a new application, conduct user testing with avatars at different realism levels to determine the optimal balance for your target audience and use case.
Project actions
- 01When creating avatars for a design project, consider how realistic you want them to be and why.
- 02Think about the purpose of your avatar: is it for a friendly chatbot, a game character, or a virtual assistant?
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive synthesis of existing research.
- +Quantitative analysis provides clear comparative data.
Limitations
It's difficult to control all variables in a real-world user study, such as individual user preferences or prior experiences with avatars.
Reliability & validity
The network meta-analysis approach increases reliability by synthesizing multiple studies. Validity is supported by the focus on established perceptual metrics.
Think critically
How might cultural differences influence the perception of avatar realism and the 'uncanny valley' effect?
Design Principles
"Optimize avatar realism to align with desired user perception: high realism for trust and attractiveness, and careful consideration for moderate realism to avoid eeriness."
Understanding user perception of avatar realism is crucial for designing engaging and effective virtual experiences. This insight informs decisions about avatar design in applications ranging from virtual social spaces to customer service bots, directly impacting user adoption and satisfaction.
What This Means for Your Design
If you make a computer character (avatar) look very real, people will find it more attractive and trustworthy. But if it's almost real, it can feel creepy.

Paragraph starter
The research indicates that virtual avatar appearance realism (VAAR) significantly influences user perception, with high realism fostering greater attractiveness and trustworthiness, while moderate realism can induce feelings of eeriness. This suggests that design decisions regarding avatar fidelity should be carefully aligned with the intended user experience and application context.
