RT Journal Article SR Electronic T1 Real-world body orientation impacts virtual navigation experience and performance JF bioRxiv FD Cold Spring Harbor Laboratory SP 2023.02.10.527966 DO 10.1101/2023.02.10.527966 A1 Hyuk-June Moon A1 Hsin-Ping Wu A1 Emanuela De Falco A1 Olaf Blanke YR 2023 UL http://biorxiv.org/content/early/2023/02/12/2023.02.10.527966.abstract AB Most human navigation studies in MRI rely on virtual navigation. However, the necessary supine position in MRI makes it fundamentally different from daily ecological navigation. Nonetheless, until now, no study has assessed whether differences in physical body orientation (BO) affect participants’ experienced BO during virtual navigation. Here, combining an immersive virtual reality (VR) navigation task with subjective BO measures and implicit behavioral measures, we demonstrate that physical BO (either standing or supine) modulated experienced BO. Also, we show that standing upright BO is preferred during spatial navigation: participants were more likely to experience a standing BO and were better at spatial navigation when standing upright. Importantly, we report that showing a supine virtual agent reduces the conflict between the preferred BO and physical supine BO. Our study provides critical, but missing, information regarding experienced BO during virtual navigation, which should be considered cautiously when designing navigation studies, especially in MRI.Visual Abstract Competing Interest StatementThe authors have declared no competing interest.
