Psychol."],"abstract":"<jats:p>Human observers are capable of perceiving the motion of moving objects relative to the stationary world, even while undergoing self-motion. Perceiving world-relative object motion is complicated because the local optical motion of objects is influenced by both observer and object motion, and reflects object motion in observer coordinates. It has been proposed that observers recover world-relative object motion using global optic flow to factor out the influence of self-motion. However, object-motion judgments during simulated self-motion are biased, as if the visual system cannot completely compensate for the influence of self-motion. Recently, Xie et al. demonstrated that humans are capable of accurately judging world-relative object motion when self-motion is real, actively generated by walking, and accompanied by optic flow. However, the conditions used in that study differ from those found in the real world in that the moving object was a small dot with negligible optical expansion that moved at a fixed speed in retinal (rather than world) coordinates and was only visible for 500\u2009ms. The present study investigated the accuracy of object motion perception under more ecologically valid conditions. Subjects judged the trajectory of an object that moved through a virtual environment viewed through a head-mounted display. Judgments exhibited bias in the case of simulated self-motion but were accurate when self-motion was real, actively generated, and accompanied by optic flow. The findings are largely consistent with the conclusions of Xie et al. and demonstrate that observers are capable of accurately perceiving world-relative object motion under ecologically valid conditions.<\/jats:p>","DOI":"10.3389\/fpsyg.2022.1068454","type":"journal-article","created":{"date-parts":[[2023,1,12]],"date-time":"2023-01-12T06:52:04Z","timestamp":1673506324000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["The accuracy of object motion perception during locomotion"],"prefix":"10.3389","volume":"13","author":[{"given":"Oliver W.","family":"Layton","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melissa S.","family":"Parade","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brett R.","family":"Fajen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,1,12]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"9","DOI":"10.1089\/cpb.2007.9935","article-title":"Depth perception in virtual reality: distance estimations in peri- and extrapersonal space","volume":"11","author":"Armbr\u00fcster","year":"2008","journal-title":"Cyberpsychol.
