视觉允许障碍物检测和回避。盲人使用其剩余的完整感觉来维持这些功能的补偿机制知之甚少。我们调查了先天失明的参与者使用舌头显示单元检测和避免障碍物的能力，舌头显示单元是一种感觉替代装置，使用舌头作为通往大脑的门户。我们发现，先天性失明的参与者在使用舌头显示单元检测和避免障碍物方面比正常对照组更好。障碍物的大小和回避策略对成绩有显着影响：大障碍物比小障碍物更容易被检测到，绕过障碍物比越过障碍物更容易被回避。这些数据扩展了我们早期的研究结果，即当使用感官替代设备时，盲人参与者不仅在虚拟导航任务中而且在人类大小的障碍课程中有效导航时都优于有视力的控制。NeuroReport 22：342-347（C）2011年威科健康垂直酒吧Lippincott威廉姆斯&威尔金斯。
Vision allows for obstacle detection and avoidance. The compensatory mechanisms involved in maintaining these functions in blind people using their remaining intact senses are poorly understood. We investigated the ability of congenitally blind participants to detect and avoid obstacles using the tongue display unit, a sensory substitution device that uses the tongue as a portal to the brain. We found that congenitally blind were better than sighted control participants in detecting and avoiding obstacles using the tongue display unit. Obstacles size and avoidance strategy had a significant effect on performance: large obstacles were better detected than small ones and step-around obstacles were better avoided than step-over ones. These data extend our earlier findings that when using a sensory substitution device, blind participants outperform sighted controls not only in a virtual navigation task but also during effective navigation within a human-sized obstacle course.
