“…Recent reviews provide comprehensive insights into various haptic technologies and their interactions with virtual objects (Giri et al, 2021;Adilkhanov et al, 2022). Although some studies have explored the use of haptics in virtual crowds, specifically to enhance the interaction with others (Hoppe et al, 2020;Della Longa et al, 2022), the majority of these have focused solely on tactile feedback (Krogmeier et al, 2019;Koilias et al, 2020a;Berton et al, 2022;Monica and Aleotti, 2023), with limited research on force-feedback displays in virtual crowd scenarios.…”

“…Wearable haptic vests have been utilized in social interactions, particularly to simulate collisions with virtual people in crowds. According to the findings of the study by Monica and Aleotti (2023), proximity-based vibrotactile haptic feedback supplied by a wearable haptic vest can considerably decrease collisions with barriers in virtual environments even with poor eyesight (e.g., walking backward or in a poorly lit environment). Krogmeier et al (2019) compared various intensities of tactile feedback with nonhaptic feedback in a virtual reality configuration where virtual characters ran against a participant standing at a crosswalk.…”

Research has shown that incorporating haptics into virtual environments can increase sensory fidelity and provide powerful and immersive experiences. However, current studies on haptics in virtual interactions primarily focus on one-on-one scenarios, while kinesthetic haptic interactions in large virtual gatherings are underexplored. This study aims to investigate the impact of kinesthetic haptics on eliciting emotional responses within crowded virtual reality (VR) scenarios. Specifically, we examine the influence of type or quality of the haptic feedback on the perception of positive and negative emotions. We designed and developed different combinations of tactile and torque feedback devices and evaluated their effects on emotional responses. To achieve this, we explored different combinations of haptic feedback devices, including “No Haptic,” “Tactile Stimulus” delivering tactile cues, and “Haptic Stimulus” delivering tactile and torque cues, in combination with two immersive 360-degree video crowd scenarios, namely, “Casual Crowd” and “Aggressive Crowd.” The results suggest that varying the type or quality of haptic feedback can evoke different emotional responses in crowded VR scenarios. Participants reported increased levels of nervousness with Haptic Stimulus in both virtual scenarios, while both Tactile Stimulus and Haptic Stimulus were negatively associated with pleasantness and comfort during the interaction. Additionally, we observed that participants’ sense of touch being real was enhanced in Haptic Stimulus compared to Tactile Stimulus. The “Haptic Stimulus” condition had the most positive influence on participants’ sense of identification with the crowd.
