Exploring Remote Collaborative Tasks: The Impact of Avatar Representation on Dyadic Haptic Interactions in Shared Virtual Environments

TL;DR

This research investigates how avatar representation influences social presence in dyadic haptic interactions within shared virtual environments, revealing that visual avatars enhance social perception without affecting task performance.

Contribution

It is the first study to systematically examine the combined effects of avatar representation and haptic interaction on social presence and task outcomes in SVEs.

Findings

Avatar of the partner significantly increases perceived social presence.

Haptic interaction alone suffices for task execution, with no performance difference across avatar conditions.

Avatar presence does not influence force effort or task performance.

Abstract

This study is the first to explore the interplay between haptic interaction and avatar representation in Shared Virtual Environments (SVEs). Specifically, how these factors shape users' sense of social presence during dyadic collaborations, while assessing potential effects on task performance. In a series of experiments, participants performed the collaborative task with haptic interaction under four avatar representation conditions: avatars of both participant and partner were displayed, only the participant's avatar was displayed, only the partner's avatar was displayed, and no avatars were displayed. The study finds that avatar representation, especially of the partner, significantly enhances the perception of social presence, which haptic interaction alone does not fully achieve. However, neither the presence nor the type of avatar representation impacts the task performance or participants' force effort of the task, suggesting that haptic interaction provides sufficient interaction cues for the execution of the task. These results underscore the significance of integrating both visual and haptic modalities to optimize remote collaboration experiences in virtual environments, ensuring effective communication and a strong sense of social presence.
