为了评估视觉和前庭信息对人类导航的贡献，五个蒙住眼睛的受试者使用移动机器人沿着三角形路径的两侧被动移动。受试者被要求在 7×6 米和 38×38 米的房间中蒙住眼睛或在全视野下驾驶机器人到起点来完成三角形。房间尺寸对表演产生显着影响：在较小的环境中，蒙住眼睛的反应总是太短，而当允许视觉反馈时，受试者正确地到达起点。相反，在较大的房间中，受试者在被蒙住眼睛的情况下做出了正确的反应，但在全视野下行驶的距离明显超出了要求的距离。我们的数据表明，前庭导航对存储的（环境知识）和当前的视觉信息都高度敏感。
To assess the contribution of visual and vestibular information on human navigation, five blindfolded subjects were passively displaced along two sides of a triangular path using a mobile robot. Subjects were required to complete the triangle by driving the robot to the starting point either blindfolded or in full vision in a 7×6-m and a 38×38-m room. Room dimensions exerted a significant effect on performances: in the smaller environment blindfolded responses were always too short whereas subjects correctly reached the starting point when visual feedback was allowed. On the contrary, in the larger room subjects correctly responded while blindfolded but drove significantly farther than requested in full vision. Our data show that vestibular navigation is highly sensitive to both stored (knowledge of environment) and current visual information.
