Designing chatbot avatars with higher levels of anthropomorphism significantly enhances user experience by fostering perceived empathy and trust, which are stronger drivers than perceived intelligence alone. This user-centred design research insight is drawn from a 2025 study published in Frontiers in Computer Science. Using Within-subjects experimental design with structural equation modeling (sem). with 160 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize avatar design that fosters emotional connection and trust, as these are more critical for positive user experience than simply conveying high intelligence.

Key Findings

  • 01Direct effects of anthropomorphism and perceived intelligence on user experience were not statistically significant.
  • 02The combined influence of anthropomorphism and perceived intelligence on user experience was significantly mediated by perceived empathy and trust.
  • 03Highly anthropomorphic avatars led to increased perceived empathy and trust, which in turn improved user experience.

Application

Design takeaway

Prioritize avatar design that fosters emotional connection and trust, as these are more critical for positive user experience than simply conveying high intelligence.

How to apply

When designing chatbot interfaces, invest in the visual and behavioral characteristics of the avatar to make it more anthropomorphic, aiming to build user empathy and trust.

Project actions

  • 01Consider how the visual design of an interface element can evoke emotional responses.
  • 02When testing user experience, include measures for trust and empathy alongside task completion.
03

Method & Evidence

AimTo investigate how anthropomorphism and perceived intelligence in chatbot avatars influence user experience, and to understand the mediating roles of perceived empathy and trust.
MethodWithin-subjects experimental design with structural equation modeling (SEM).
ProcedureParticipants interacted with chatbot avatars varying in anthropomorphism (high vs. low) and perceived intelligence (high vs. low). Their perceptions of empathy, trust, and overall user experience were measured and analyzed using SEM to determine the relationships and mediating effects.
Sample160 participants
ContextHuman-AI interaction, specifically with intelligent chatbots.

Variables

IV["Anthropomorphism of chatbot avatar (high vs. low)","Perceived intelligence of chatbot avatar (high vs. low)"]
DV["User experience (UX)"]
CV["Participant demographics (potentially)","Chatbot task (kept consistent)"]
04

Strengths & Limitations

Strengths

  • +Utilized a robust experimental design (within-subjects).
  • +Employed advanced statistical analysis (SEM) to explore mediating relationships.

Limitations

The study's findings might be specific to the types of avatars and tasks used; results may vary with different cultural contexts or chatbot functionalities.

Reliability & validity

The use of SEM in a within-subjects design with a reasonable sample size suggests good internal validity for the tested relationships. Reliability would depend on the specific scales used to measure empathy, trust, and UX.

Think critically

To what extent can perceived empathy and trust be designed into an avatar, and are there ethical considerations in designing for emotional connection with AI?

05

Design Principles

"Emotional resonance in AI interfaces is a key driver of user experience."

This research highlights that for effective human-AI interaction, designers should prioritize emotional connection and relatable design elements over solely focusing on a chatbot's perceived intelligence. Understanding these mediating factors allows for more targeted design strategies to improve user satisfaction and engagement.

06

What This Means for Your Design

Making a chatbot's avatar look and feel more like a person (even if it's not super smart) makes people trust it more and feel more understood, which makes using the chatbot a better experience.

How to use in your project

  • 1.Reference this study when justifying design choices for avatars or interactive elements that aim to build user rapport.
  • 2.Use the findings to explain why a particular design approach was chosen to enhance user trust and empathy.
