Abstract\u2014 The advance of hybrid technologies allowed the creation of environments where humans and virtual agents may instantiate daily social interactions. However, to enable people to have effective interactions with virtual avatars, it is fundamental to understand the role of the surrounding environment in social scenarios. To this aim, we designed a novel paradigm in virtual reality to unveil those mechanisms underpinning the perception of others\u2019 affective states modulated by a dynamic experience of the surrounding virtual environment. Specifically, participants made a virtual promenade within low\/high arousing environments and were then asked to judge the arousal level of an avatar\u2019s body posture at the end of the scene. Here, we present an eye-tracking (Experiment 1) and event-related potentials (ERPs) (Experiment 2) pilot study. In Experiment 1, we found that the dynamic experience of those virtual environments perceived as low arousing was associated with higher subjective arousal scores and higher fixation times on the avatar\u2019s body. In Experiment 2, we found an increased P200 amplitude when the avatar was presented after the experience of the low arousing environment. Overall, both behavioral and EEG evidence highlighted that the dynamic experience of different arousing environments alters attentional mechanism during the observation of the avatars\u2019 body. Specifically, our results suggest that the experience of a relaxing environment may broaden participants\u2019 attentional resources, thus leading to enhanced behavioral and cerebral responses during the observation of the body posture. These preliminary results show the effectiveness of virtual reality in studying how human social behavior is affected by the dynamic experience of virtual environments. Such knowledge will be beneficial for designing future environments where social activities are expected to occur, eventually promoting the creation of healthy hybrid spaces.<\/p>\n\n\n\n

“Using Eye Tracking to Aid The Design Of Human-Machine-Interfaces (HMIs) in Industrial Applications”<\/strong><\/h4>\n\n\n\n

Abstract\u2014 In the vision of a \u201chybrid society\u201d, the interaction between humans and embodied digital technologies is envisaged to be as smooth and seamless as human-human interaction. In the foreseeable future, however, humans will undoubtedly continue to interact with many machines through designated human-machine interfaces (HMIs). Designing such HMIs for production settings presents a particular challenge, as users may vary in their experience and expertise. Moreover, challenging issues of a specific HMI are often difficult to verbalize and therefore hard to obtain through user report and expert interviews alone. To make interactions through HMIs smooth, it is therefore crucial to evaluate HMIs with state-of-the-art technologies that do not require explicit report. Here we demonstrate the use of eye tracking for HMI design in an industrial production setting, where smooth human-machine interaction is particularly critical to ensure safe and efficient operation. Using a real-life example, we illustrate how eye tracking allows dissociating users\u2019 difficulties to find a particular interaction item (\u201csearch\u201d) from their challenges in realizing that it is indeed the item to be operated (\u201cverification\u201d). We argue that this distinction is crucial for (re-)designing HMIs to optimize usability and that the usefulness of eye tracking extends beyond the specific context to human-machine interaction in general.<\/p>\n\n\n\n

“Reducing Prejudice Via VR”<\/strong><\/h4>\n\n\n\n

Abstract\u2014 In the theory-driven quest to resolve human prejudice, psychological scholars have directed their attention towards new media and technologies, hoping to overcome the limitations found in conventional anti-prejudice interventions. Rather crucially, this has involved Virtual Reality (VR), a technology designed to fully immerse users in lifelike digital environments. As VR may facilitate both intense perspective-taking experiences as well as low-threshold intergroup contact, it has been proposed as a valuable tool against many forms of outgroup bias, including racism, ableism, and transphobia. Yet, with the respective literature growing rapidly, a synthesis of extant findings seems much needed. In this ongoing meta-analytical project, we aggregate evidence from prior studies that experimentally compared VR-based prejudice interventions to either (a) alternative interventional strategies or (b) no\/mock treatment groups. Furthermore, we investigate the role of several theoretically relevant moderator variables (e.g., the type of outcome measure or addressed bias) in order to gain more nuanced insight into the merit of VR as an anti-prejudice platform. Based on our findings, we will discuss potential improvements to this emerging virtual practice.<\/p>\n\n\n\n
