In order to develop design criteria for interpretive nature trails for the visually impaired, this study first investigated existing trails to determine how effective they were, and discover what problems have emerged in their administration. Since it was not feasible to survey visually impaired persons directly, certified orientation and mobility instructors were surveyed to obtain information on the opinions of visually impaired persons.

视障人士自然小径调查

为了为视障人士制定解说性自然小径的设计标准，本研究首先调查了现有小径以确定它们的有效性，并发现其管理中出现了哪些问题。由于直接调查视障人士不可行，因此对经过认证的定向和行动指导员进行了调查，以获取有关视障人士意见的信息。
