“…In addition to self‐reported data, past virtual reality experiments have captured physiological data by using EDA, 12‐15 which can be indicative of high levels of arousal or stress, 16 as well as eye gaze behavior such as eye fixations, 17‐19 which can be indicative of not only attention, 18 but anxiety, 17 engagement, 20 as well as social functioning 19 . Virtual reality studies capturing EDA have explored public speaking anxiety, 17 and posttraumatic stress disorder 21 among other interests.…”

As motion-sensing devices become more accessible to consumers, it is important to understand how users experience embodiment when using these devices. In our 3 × 2 between-groups study, we explored eye fixations and electrodermal activity (EDA) in order to more objectively understand potential interaction effects between the self-avatar body, and the presence of a mirror within the context of low-budget embodiment. We developed six experimental conditions concerning Body (human, mannequin, and zombie self-avatars) and Mirror (mirror and no mirror) factors, and presented participants with a virtual environment in which they could control their self-avatars by using HTC Vive controllers and trackers. In addition to eye fixations and EDA, we assessed self-reported data concerning body ownership, agency, self-location, as well as enjoyment of the experience. Our results suggest that the Body may have been more influential in eliciting body ownership than the Mirror, and that an interaction effect between Gender and Body may influence eye gaze behavior. Additionally, female participants reported significantly higher agency than males. We consider logical next steps for similar research which might elaborate upon our findings.

“…In future work, we will explore the interaction effects of crowd movement variations (speed, direction, and density) on human movement behavior, the effects of virtual pedestrians' appearance and motion assigned to a crowd on participants' emotional reactivity [97], the effects of tactile feedback during immersive walking in virtual crowds [98], and the effects of self-avatars on human movement and flocking behavior. We also plan to collect other forms of data, such as eye tracking, electrodermal activity, and subjective ratings [73,99], to study the interactions between humans and virtual crowds. Finally, experimentation with data-driven techniques for simulating the movement of virtual pedestrians will also be explored.…”

“…To analyze and evaluate human behavior, behavioral, motion, and electrophysiological recording techniques are typically used [ 19 , 39 , 40 , 70 , 71 , 72 , 73 ]. In this study, to determine how participants coordinated their movement compared to simulated characters, we computed measurements related to the task and the objectives of the experiment.…”

This paper describes our investigation on how participants coordinate movement behavior in relation to a virtual crowd that surrounds them while immersed in a virtual environment. The participants were immersed in a virtual metropolitan city and were instructed to cross the road and reach the opposite sidewalk. The participants performed the task ten times. The virtual crowd that surrounded them was scripted to move in the same direction. During the experiment, several measurements were obtained to evaluate human movement coordination. Moreover, the time and direction in which the participants started moving toward the opposite sidewalk were also captured. These data were later used to initialize the parameters of simulated characters that were scripted to become part of the virtual crowd. Measurements were extracted from the simulated characters and used as a baseline to evaluate the movement coordination of the participants. By analyzing the data, significant differences between the movement behaviors of the participants and the simulated characters were found. However, simple linear regression analyses indicated that the movement behavior of participants was moderately associated with the simulated characters’ movements when performing a locomotive task within a virtual crowd population. This study can be considered as a baseline for further research that evaluates the movement coordination of participants during human–virtual-crowd interactions using measurements obtained by the simulated characters.

“…Additionally, developing experimental scenarios in which participants have to perform more complex locomotion tasks, e.g., side stepping or passing through narrow hallways, might be necessary to further understand the impact that the motion artifacts have on the sense of self-agency. Finally, in our future work, we would like to explore whether the sense of self-agency is affected when providing tactile feedback [52,53] to participant's body as well as how participants perceive self-agency when embodied to a virtual character with variations on his/her appearance [54,55].…”

The Effects of Motion Artifacts on Self-Avatar Agency

One way of achieving self-agency in virtual environments is by using a motion capture system and retargeting user’s motion to the virtual avatar. In this study, we investigated whether the self-agency is affected when motion artifacts appear on top of the baseline motion capture data assigned to the self-avatar. For this experiment, we implemented four artifacts: noise, latency, motion jump, and offset rotation of joints. The data provided directly from the motion capture system formed the baseline of the study. We developed three observation tasks to assess self-agency: self-observation, observation through a virtual mirror, and observation during locomotion. A questionnaire was adopted and used to capture the self-agency of participants. We analyzed the collected responses of participants to determine whether the motion artifacts significantly altered the participants’ sense of self-agency. The obtained results indicated that participants are not always sensitive to the motion artifacts assigned to the self-avatar, but the sense of self-agency is dependent on the observation task they were asked to perform. Implications for further research are discussed.
