Virtual　reality　technology　has　shown　potential　for　rehabilitation　training,　and　spatial　presence　and　flow　experience　have　emerged　as　two　important　factors　for　explaining　the　virtual　reality　experience.　We　designed　a　new　non-immersive　upper　limb　rehabilitation　training　system　to　analyze　the　effects　of　spatial　presence　and　flow　on　the　user　experience　in　virtual　reality　and　its　acceptance　of　technology　using　a　technology　acceptance　model.　This　study＇s　results　showed　that　spatial　presence　has　no　significant　effect　on　perceived　usefulness　(β　=　0.102,　p　=　0.062),　some　degree　of　positive　effect　on　perceived　ease　of　use　(β　=　0.197,　p　=　0.010),　and　a　significant　positive　effect　on　the　flow　experience　(β　=　0.535,　p　©　2024　Elsevier　B.V.
