“…This may be more so when there is a mismatch between the expected walking speed and the movement within the VR environment. 33 Further research is needed to understand the cause and effects of VR induced cybersickness before we can fully mitigate the problem.…”

Introduction The combination of virtual reality (VR) with an omnidirectional walking platform (ODWP) may have potential in rehabilitation settings. However, its use, acceptance, safety, and effectiveness are unclear. This preliminary study aims to understand the feasibility, safety, and user experience (including investigating the onset of cybersickness) while walking on the ODWP with fully immersive VR. Methods Participants engaged with eight immersive VR walking scenarios. The scenarios were created using 360-degree videos and were programmed to run with the ODWP. Safety modifications for the ODWP were made, with the addition of parallel bars. Quantitative feedback on the perceived safety and acceptance of using VR with an ODWP for rehabilitation was collected. Cybersickness was evaluated using the Simulation Symptoms Questionnaire (SSQ). Results Thirty-five participants ( n = 8 physiotherapists, n = 27 healthy adults) were recruited for this study. The mean perceived safety score was 78.9/100 and acceptance was 64.5/100. Seventy-one percent of participants experienced mild to moderate symptoms of cybersickness as reported on the SSQ. The SSQ scores were not correlated to participant age or simulation exposure time. Conclusion VR while using ODWP has the potential for rehabilitation, however, more consideration is needed to address acceptance and cybersickness.

“…Traditional ceramic art mostly relies on manual skills and empirical judgment, and the unavoidable uncertainty in the production process is part of its charm [9][10]. However, with the introduction of 3D modeling technology, designers can accurately plan every detail of a ceramic work before production.…”

This paper is based on the research of visual shell related technology of 3D modeling method to extract the corresponding points of the graphical shell, through matching, filtering and denoising operations, to obtain the accurate 3D visualization model and provide new creative ideas and paths for contemporary ceramic art. In the actual ceramic membrane visualization feature extraction, six feature quantities of ceramic membrane, namely, area, aspect ratio, area perimeter, circularity, diagonal length, and angular second-order moments, can be obtained. The application of the visualization technique proposed in this paper to teaching ceramic production art was assessed by the performance of the knowledge answer questions. Regarding the average score, the experimental group (75.5) performed significantly better than the control group (63.6). Significant differences were found between the experimental and control groups in mental rotation (P=0.03<0.05), spatial visualization (P=0.006<0.05), and spatial reasoning skills (F=6.98, P=0.014<0.05). However, the two groups had no significant difference in spatial orientation (P=0.13>0.05). This suggests that the immersive learning environment of visualization technology can significantly enhance learners’ spatial reasoning skills, mental rotation, and spatial orientation.

“…To decrease this visualvestibular conflict, there are two main approaches: minimizing or blurring the field of view to reduce visual information during motion (Budhiraja et al, 2017;Fernandes & Feiner, 2016), or improving vestibular information through the presentation of tactile sensations (Liu et al, 2019;Plouzeau et al, 2017;Weech et al, 2018). In walking on an omni-directional treadmill, cybersickness varies with changes in the speed of movement (Lohman & Turchet, 2022). Based on this, we predicted that synchronized foot vibrations, in conjunction with optic flow during virtual walking, could reduce instances of cybersickness.…”

Human locomotion is most naturally achieved through walking, which is good for both mental and physical health. To provide a virtual walking experience to seated users, a system utilizing foot vibrations and simulated optical flow was developed. The current study sought to augment this system and examine the effect of an avatar's cast shadow and foot vibrations on the virtual walking experience and cybersickness. The omnidirectional movie and the avatar's walking animation were synchronized, with the cast shadow reflecting the avatar's movement on the ground. Twenty participants were exposed to the virtual walking in six conditions (with/without foot vibrations and no/short/long shadow) and were asked to rate their sense of telepresence, walking experience, and occurrences of cybersickness. Our findings indicate that the synchronized foot vibrations enhanced telepresence as well as self-motion, walking, and leg-action sensations, while also reducing instances of nausea and disorientation sickness. The avatar's cast shadow was found to improve telepresence and leg-action sensation, but had no impact on self-motion and walking sensation. These results suggest that observation of the self-body cast shadow does not directly improve walking sensation, but is effective in enhancing telepresence and leg-action sensation, while foot vibrations are effective in improving telepresence and walking experience and reducing instances of cybersickness.
