Online platforms for remote immersive Virtual Reality testing: an emerging tool for experimental behavioral research

Virtual Reality (VR) technology is gaining in popularity as a research tool for studying human behavior. However, the use of VR technology for remote testing is still an emerging field. This study aimed to evaluate the feasibility of conducting remote VR behavioral experiments that require millisecond timing. Participants were recruited via an online crowdsourcing platform and accessed the classic cognitive phenomenon "Inhibition of Return" through a web browser using their own VR headset or desktop computer (68 participants in each group). Results confirm previous research that remote participants using desktop computers can be used effectively for conducting time-critical cognitive experiments. However, inhibition of return was only partially replicated for the VR headset group. Exploratory analyses revealed that technical factors, such as headset type, were likely to significantly impact variability and must be mitigated to obtain accurate results. This study demonstrates the potential for remote VR testing to broaden the research scope and reach a larger participant population. Crowdsourcing services appear to be an efficient and effective way to recruit participants for remote behavioral testing using high-end VR headsets.
