“…A VRPN plugin [38] to DIVE was used to enable the logging of tracking data and events. The behavior of the characters was controlled using Tcl scripts which called procedures in Platform Independent Architecture for Virtual Characters and Avatars (PIAVCA) [39]. The PIAVCA is a library for controlling virtual characters through the use of motion data.…”

Abstract-This paper presents the quantitative and qualitative findings from an experiment designed to evaluate a developing model of affective postures for full-body virtual characters in immersive virtual environments (IVEs). Forty-nine participants were each requested to explore a virtual environment by asking two virtual characters for instructions. The participants used a CAVE-like system to explore the environment. Participant responses and their impression of the virtual characters were evaluated through a wide variety of both quantitative and qualitative methods. Combining a controlled experimental approach with various data-collection methods provided a number of advantages such as providing a reason to the quantitative results. The quantitative results indicate that posture plays an important role in the communication of affect by virtual characters. The qualitative findings indicated that participants attribute a variety of psychological states to the behavioral cues displayed by virtual characters. In addition, participants tended to interpret the social context portrayed by the virtual characters in a holistic manner. This suggests that one aspect of the virtual scene colors the perception of the whole social context portrayed by the virtual characters. We conclude by discussing the importance of designing holistically congruent virtual characters especially in immersive settings.

This paper presents an experiment that investigates the importance of nonverbal behavioral cues when designing affective virtual characters for an immersive virtual environment (IVE).Forty-nine participants were each instructed to explore a virtual environment by asking two virtual characters for instructions in a CAVE™-like system. The underlying emotional state of the virtual characters was depicted through the use of nonverbal behavioral cues. We focus on two types of behavioral cues (facial expressions and posture) and two emotional states (Angry and Sad).The results indicate that posture plays an important role in the communication of affect by virtual characters in the case when the state portrayed is 'anger', but not when it is 'sad'. We conclude by discussing the importance of designing holistically congruent virtual characters especially under immersive settings.
