过去几十年来，已经开发了各种便携式或可穿戴导航系统，以帮助视障人士在已知或未知的室内或室外环境中进行导航。这些系统主要分为三类：电子出行辅助设备 (ETA)、电子定向辅助设备 (EOA) 和位置定位设备 (PLD)。本文对便携式/可穿戴障碍物检测/回避系统（ETA 的一个子类别）进行了比较调查，旨在让研究界和用户了解这些系统的功能以及视障人士辅助技术的进展。该调查基于系统的各种特征和性能参数，将其分类，并给出定性定量测量。最后，它提供了一个排名，该排名仅作为参考点，而不是对这些系统的批评。
The last decades a variety of portable or wearable navigation systems have been developed to assist visually impaired people during navigation in known or unknown, indoor or outdoor environments. There are three main categories of these systems: Electronic travel aids (ETAs), electronic orientation aids (EOAs), and position locator devices (PLDs). This paper presents a comparative survey among portable/wearable obstacle detection/avoidance systems (a subcategory of ETAs) in an effort to inform the research community and users about the capabilities of these systems and about the progress in assistive technology for visually impaired people. The survey is based on various features and performance parameters of the systems that classify them in categories, giving qualitative-quantitative measures. Finally, it offers a ranking, which will serve only as a reference point and not as a critique on these systems.
