Using　VR　in　reclining　&　lying　positions　is　getting　common　for　users,　but　upward　views　caused　by　posture　have　to　be　redirected　to　be　parallel　to　the　ground　as　when　users　are　standing.　This　affects　users＇　locomotion　performances　in　VR　due　to　potential　physical　restrictions,　and　the　visual-vestibular-proprioceptive　conflict.　This　paper　is　among　the　first　to　investigate　the　suited　locomotion　methods　and　how　reclining　&　lying　positions　and　redirection　affect　them　in　such　conditions.　A　user-elicitation　study　was　carried　out　to　construct　a　set　of　locomotion　methods　based　on　users＇　preferences　when　they　were　in　different　reclining　&　lying　positions.　A　second　study　developed　user-preferred　＇tapping＇　and　＇chair　rotating＇　gestures,　by　evaluating　their　performances　at　various　body　reclining　angles,　we　measured　the　general　impacts　of　posture　and　redirection.　The　results　showed　that　these　methods　worked　effectively,　but　exposed　some　shortcomings,　and　users　performed　worst　at　45°　reclining　angles.　Finally,　four　upgraded　methods　were　designed　and　verified　to　improve　the　locomotion　performances.　　©　2023　ACM.
