Abstract

Virtual humans, including virtual agents and avatars, play an increasingly important role as VR technology advances. For example, virtual humans are used as digital bodies of users in social VR or as interfaces for AI assistants in online financing. Interpersonal trust is an essential prerequisite in real-life interactions, as well as in the virtual world. However, to date, there are no established interpersonal trust measurement tools specifically for virtual humans in virtual reality. This study fills the gap, by contributing a novel validated behavioural tool to measure interpersonal trust towards a specific virtual social interaction partner in social VR. This validated paradigm is inspired by a previously proposed virtual maze task that measures trust towards virtual characters. In the current study, a variant of this paradigm was implemented. The task of the users (the trustors) is to navigate through a maze in virtual reality, where they can interact with a virtual human (the trustee). They can choose to (1) ask for advice and (2) follow the advice from the virtual human if they want to. These measures served as behavioural measures of trust. A validation study with 70 participants indicates that our paradigm can be used to measure differences in interpersonal trust towards virtual humans and may serve as a valuable research tool to study trust in virtual reality.

Contents

  • The "Experiments" folder contains the applications and supplementary videos used in the validation study (Lin et al., 2023a). These applications include the interaction tutorial, the Investment Game task (high- and low-trustworthiness conditions), and the Virtual Maze task (high- and low-trustworthiness conditions). The "Tutorial Videos" were also part of the experiment as essential framing materials. For details on the procedure and experimental setup, please refer to the publication.

  • The "Demo" folder contains the demo application (Lin et al., 2023b), which is an adapted version with English audio and text, redesigned environment, and a simplified process focused on showcasing the core concepts.
