闻香识路：虚拟现实中嗅觉调节空间估计与路径整合

中文摘要 AI 辅助

空间认知使个体能够感知和解释空间关系、估计位置并在周围环境中导航。虽然视觉起主导作用，但其他感觉模态，尤其是嗅觉，在视觉线索有限时可以支持空间处理。本文通过使用风扇介导的嗅觉设备，探讨了虚拟现实（VR）环境中气味传递的效果。我们进行了两项正式研究，以评估对空间信息获取的影响。研究1（N=24）考察了参与者在沿直线路径行走时，使用两种不同嗅觉设备定位气味源的能力。研究2（N=19）采用了三角形完成任务，参与者在不同的旋转角度和嗅觉条件下尝试返回起点。结果表明，气味传递反馈在两项研究中以不同方式影响了空间行为。在研究1中，视觉-嗅觉错位产生了系统性方向偏差，但未提高绝对定位准确性。在研究2中，距离调节的气味传递反馈减少了终端归位误差，但也增加了行进距离和完成时间，表明采用了更审慎的目标确认策略。

英文摘要

Spatial cognition enables individuals to perceive and interpret spatial relationships, estimate locations, and navigate within their surroundings. While vision plays a dominant role, other sensory modalities, particularly olfaction, can support spatial processing when visual cues are limited. This paper explores the effects of scent-delivery within virtual reality (VR) environments by using fan-mediated olfactory devices. We conducted two formal studies to evaluate the effects on spatial information acquisition. Study 1 (N=24) examined the participants' ability to localize a scent source while walking a linear path using two different olfactory devices. Study 2 (N=19) employed a triangle completion task, in which participants attempted to return to their starting point under varying rotation angles and olfactory conditions. Results indicate that scent-delivery feedback influenced spatial behavior in distinct ways across the two studies. In Study 1, visual-olfactory misalignment produced systematic directional biases without improving absolute localization accuracy. In Study 2, distance-modulated scent-delivery feedback reduced terminal homing error but also increased traveled distance and completion time, suggesting a more deliberate goal-confirmation strategy.
