“…Coburn et al (2020) advocate multiple transition styles (locomotion) for users. We can hypothesize that users in a VR application for office-like tasks will be sitting (Zielasko et al 2017;Zielasko and Riecke 2021). Zielasko et al (2019) had participants move by leaning (forward and backward).…”

This narrative review synthesizes and introduces 386 previous works about virtual reality-induced symptoms and effects by focusing on cybersickness, visual fatigue, muscle fatigue, acute stress, and mental overload. Usually, these VRISE are treated independently in the literature, although virtual reality is increasingly considered an option to replace PCs at the workplace, which encourages us to consider them all at once. We emphasize the context of office-like tasks in VR, gathering 57 articles meeting our inclusion/exclusion criteria. Cybersickness symptoms, influenced by fifty factors, could prevent workers from using VR. It is studied but requires more research to reach a theoretical consensus. VR can lead to more visual fatigue than other screen uses, influenced by fifteen factors, mainly due to vergence-accommodation conflicts. This side effect requires more testing and clarification on how it differs from cybersickness. VR can provoke muscle fatigue and musculoskeletal discomfort, influenced by fifteen factors, depending on tasks and interactions. VR could lead to acute stress due to technostress, task difficulty, time pressure, and public speaking. VR also potentially leads to mental overload, mainly due to task load, time pressure, and intrinsically due interaction and interface of the virtual environment. We propose a research agenda to tackle VR ergonomics and risks issues at the workplace.

“…During the experiment, the participants sat on a swivel chair without wheels, to be able to easily rotate themselves as much as they wanted without translations possibly caused by wheels. We chose sitting over standing for a few reasons; first, many people seem to prefer sitting over standing in VR [31]; second, it is more inclusive since standing is physically more difficult for many people, and third; this way we can be sure that the people do not translate (take steps around), which could confound the study. To avoid the participants getting entangled with the cable, we installed a pulley system that feeds the cable from the ceiling.…”

We propose unwinding the rotations experienced by the user of an immersive telepresence robot to improve comfort and reduce VR sickness of the user. By immersive telepresence we refer to a situation where a 360°camera on top of a mobile robot is streaming video and audio into a head-mounted display worn by a remote user possibly far away. Thus, it enables the user to be present at the robot's location, look around by turning the head and communicate with people near the robot. By unwinding the rotations of the camera frame, the user's viewpoint is not changed when the robot rotates. The user can change her viewpoint only by physically rotating in her local setting; as visual rotation without the corresponding vestibular stimulation is a major source of VR sickness, physical rotation by the user is expected to reduce VR sickness. We implemented unwinding the rotations for a simulated robot traversing a virtual environment and ran a user study (N=34) comparing unwinding rotations to user's viewpoint turning when the robot turns. Our results show that the users found unwound rotations more preferable and comfortable and that it reduced their level of VR sickness. We also present further results about the users' path integration capabilities, viewing directions, and subjective observations of the robot's speed and distances to simulated people and objects.

“…Participants in high embodied conditions learned the most. Zielasko and Riecke (2021) carry out a systematic analysis with VR experts in a workshop to find out the effect of body posture and embodied interactions on various VR experiences such as engagement, enjoyment, comfort, and accessibility. They also found higher embodied locomotion cues for walking rather than sitting.…”

“…Even though physically walking is considered to be cognitively demanding, it is considered to be the most natural interaction technique (Lages and Bowman, 2018). Zielasko and Riecke (2021) carry out a survey in which participants rated higher embodied (non-visual) locomotion cues for walking, walking in place, and arm swinging than standing, sitting, or teleportation. In a webbased desktop VR, physical walking can be replicated using a controller.…”

To incorporate immersive technologies as part of the educational curriculum, this article is an endeavor to investigate the role of two affordances that are crucial in designing embodied interactive virtual learning environments (VLEs) to enhance students’ learning experience and performance: 1) the sense of presence as a subjective affordance of the VR system, and 2) bodily engagement as an embodied affordance and the associated sense of agency that is created through interaction techniques with three-dimensional learning objects. To investigate the impact of different design choices for interaction, and how they would affect the associated sense of agency, learning experience and performance, we designed two VLEs in the context of penetrative thinking in a critical 3D task in geosciences education: understanding the cross-sections of earthquakes’ depth and geometry in subduction zones around the world. Both VLEs were web-based desktop VR applications containing 3D data that participants ran remotely on their own computers using a normal screen. In the drag and scroll condition, we facilitated bodily engagement with the 3D data through object manipulation, object manipulation. In the first-person condition, we provided the ability for the user to move in space. In other words, we compared moving the objects or moving the user in space as the interaction modalities. We found that students had a better learning experience in the drag and scroll condition, but we could not find a significant difference in the sense of presence between the two conditions. Regarding learning performance, we found a positive correlation between the sense of agency and knowledge gain in both conditions. In terms of students with low prior knowledge of the field, exposure to the VR experience in both conditions significantly improved their knowledge gain. In the matter of individual differences, we investigated the knowledge gain of students with a low penetrative thinking ability. We found that they benefited from the type of bodily engagement in the first-person condition and had a significantly higher knowledge gain than the other condition. Our results encourage in-depth studies of embodied learning in VR to design more effective embodied virtual learning environments.
