Measures of the accuracy of locomotion control were taken with blind and blindfolded sighted subjects using the natural auditory obstacle sense to locate a travel path. These measures were compared with the accuracy of visual guidance. While the blind show a greater skill than blindfolded sighted subjects in using auditory cues for guidance, auditory guidance is notably inferior to visual guidance and deteriorates markedly when smaller targets are used to define the travel path. The natural obstacle sense thus appears to give only a rudimentary perception of the presence of objects and does not provide sufficient spatial information to allow accurate locomotion control.
通过让盲人及蒙眼的视力正常受试者利用自然听觉障碍感知来确定行进路线，获取了运动控制准确性的测量数据。这些测量数据与视觉引导的准确性进行了比较。虽然盲人在利用听觉线索进行引导方面比蒙眼的视力正常受试者表现出更高的技能，但听觉引导明显不如视觉引导，并且当使用更小的目标来定义行进路线时，其准确性会显著下降。因此，自然障碍感知似乎仅能对物体的存在给出基本的感知，无法提供足够的空间信息以实现精确的运动控制。
