Beyond the Lab: Large-Scale Remote Cybersickness Research in Virtual Reality Using the VERA Platform

Cybersickness remains a major barrier for the adoption of virtual reality (VR), yet most existing knowledge is derived from laboratory-based studies with relatively small and homogeneous participant samples. In this paper, we investigate whether remote VR studies can produce cybersickness findings comparable to traditional in-lab experiments while enabling larger and more diverse participant populations. Using the Virtual Experience Research Accelerator (VERA), we deployed a remote adaptation of the standardized Cybersicker testbed for cybersickness research and collected data from N=263 participants using their own consumer VR headsets. We compared these results against a previously published in-lab dataset and a demographically matched subset of the remote sample. Across cohorts, cybersickness outcomes were consistent in direction and temporal pattern, including symptom onset trajectories, Fast Motion Sickness Scale (FMS) ratings, and Simulator Sickness Questionnaire (SSQ) responses, supporting the validity of remote cybersickness human-subjects research. Leveraging the larger remote dataset, we additionally examined demographic and individual-difference factors associated with cybersickness. These analyses confirm at scale the effects of sex, sickness susceptibility, and sickness expectation reported in smaller laboratory samples, and they add well-powered evidence on the contested relationship between age and cybersickness. These findings demonstrate that the VERA platform provides a viable means of remotely replicating laboratory-based studies and highlight its ability to support large, demographically diverse participant samples. This work establishes a validated methodological foundation for future large-scale remote studies of cybersickness and other VR research topics.

An Evaluation Study of 2D and 3D Teleconferencing for Remote Physical Therapy

The present research investigates the effectiveness of using a telepresence system compared to a video conferencing system and the effectiveness of using two cameras compared to one camera for remote physical therapy. We used Telegie as our telepresence system, which allowed users to see an environment captured with RGBD cameras in 3D through a VR headset. Since both telepresence and the inclusion of a second camera provide users with additional spatial information, we examined this affordance within the relevant context of remote physical therapy. Our dyadic study across different time zones paired 11 physical therapists with 76 participants who took on the role of patients for a remote session. Our quantitative questionnaire data and qualitative interviews with therapists revealed several important findings. First, after controlling for individual differences between participants, using two cameras had a marginally significant positive effect on physical therapy assessment scores from therapists. Second, the spatial ability of patients was a strong predictor of therapist assessment. And third, the video clarity of remote communication systems mattered. Based on our findings, we offer several suggestions and insights towards the future use of telepresence systems for remote communication.
