诺丁汉障碍指导员（NOD）是一种手持超声波辅助设备，旨在帮助视障人士在旅行时发现障碍物。NOD在用户前方7.5英尺处发射高频声波脉冲。口袋大小的辅助装置需要很少的训练，并打算与主要援助（长手杖，导犬）一起使用。本文描述了NOD的发展和两项评估研究的结果，这些研究测试了该设备的功效。
The Nottingham Obstacle Director (NOD) is an ultrasonic handheld aid designed to help visually handicapped people detect obstacles as they travel. NOD emits pulses of high-frequency sound up to 7½ feet ahead of the user. The pocket-sized secondary device requires little training and is intended to be used with a primary aid (long cane, dog guide). This article describes the development of the NOD and the results of two evaluation studies that tested the efficacy of the device.
