Gaze following by avatars increased user liking, regardless of the avatar's initial appeal. This suggests that mutual gaze can enhance social connection and positive perceptions in human-computer interaction.
Area of Science:
- Human-computer interaction
- Social psychology
- Communication studies
Background:
- Gaze is crucial for human communication, particularly in coordinating attention and establishing joint attention.
- Prior research suggests that gaze-following behaviors may enhance interpersonal liking.
- The potential for gaze-following to induce positive social perceptions warrants further investigation.
Purpose of the Study:
- To investigate whether human avatars following user gaze can increase user-perceived liking.
- To determine if gaze-following fosters positive social attributes like pleasantness, trustworthiness, and closeness.
- To examine if this effect is independent of the avatar's baseline physical appeal.
Main Methods:
- Two physically distinct human avatars were designed with eye-tracking capabilities.
- A preliminary experiment assessed participants' baseline appeal ratings for the avatars.
- The main experiment compared user ratings of avatar pleasantness, trustworthiness, and closeness when avatars engaged in gaze-following versus autonomous gaze movements.
Main Results:
- While one avatar was rated more favorably overall, both avatars were perceived as more pleasant when they followed user gaze.
- The increase in pleasantness attributed to the avatars was observed regardless of their initial baseline appeal.
- Gaze-following behavior significantly enhanced positive perceptions of the avatars.
Conclusions:
- Gaze-following behavior by avatars demonstrably fosters increased liking and positive social perceptions.
- This effect of gaze-following on liking is independent of the inherent appeal of the individual avatar.
- Findings support the hypothesis that mutual gaze can enhance social bonding and positive affect in human-avatar interactions.
