The impact of scenery and time on spatial orientation cognition in virtual reality
Sense of direction refers to the ability of users to construct mental maps based on their personal perceptions by observing or navigating scenes,allowing them to understand and interpret map information and make judgments on direction,angle,and distance.In fields such as psychology and medicine,numerous studies have shown that the sense of direction is influenced by multiple factors,including spatial memory,spatial perception,and spatial imagination.Within virtual environments,users also rely on this ability to judge direction,using virtual devices to gather scene information.This study primarily examined how users determine their orientation in virtual scenes through abilities such as spatial memory,perception,and imagination.The metric for users'sense of direction in this study included two aspects:accuracy and efficiency.Accuracy refers to the angular and distance errors between the user's and the target's orientation and position,while efficiency refers to the decision time for the user to judge the direction and the time to move to the target.Six experiments were conducted to explore the impact of visual scene differences on users'sense of direction.The experimental results showed that:① visual information is a crucial factor for users'direction judgments in virtual reality;② within similarly structured scenes,smaller spaces with more objects enhanced users'sense of direction;③ changes in scene style had little impact on users'sense of direction under constant visual range.Additionally,the accuracy of users'orientation judgments was influenced by both decision and movement time,with movement time exerting a more significant effect,while decision time had a relatively smaller impact.The findings of this study provided valuable insights for virtual reality scene design,measuring user sense of direction,optimizing scene layouts,and enhancing user navigation capabilities.
