We developed a new kit to assemble three-dimensional (3D) tactile maps for orientation and mobility (O&M) training provided to persons with visual impairments. This study evaluated the effects of verbal explanations combined with 3D tactile map kits in improving understanding, recall, and walking along an unfamiliar route in comparison with the effects of only verbal explanation. The 3D tactile maps provided participants having severe visual impairments and little experience with tactile maps with a better understanding and recall of the environmental information concerning the route and landmarks. Participants who used the 3D tactile maps could find specific landmarks set as tasks more accurately and arrive at the destination alone getting lost less frequently. Tactile maps composed of 3D points, lines, and areal parts are useful as a support aid for O&M training because they have high tactile readability and can provide the environmental information that individuals with visual impairment require.
我们开发了一种新的套件，用于组装用于视障人士定向和移动 (O&M) 训练的三维 (3D) 触觉地图。本研究评估了口头解释与 3D 触觉地图套件相结合对提高理解、回忆和在不熟悉路线上行走的效果，与仅进行口头解释的效果进行了比较。对于严重视力障碍且几乎没有使用过触觉地图经验的参与者来说，3D 触觉地图提供了更好地理解和回忆与路线和地标有关的环境信息。使用 3D 触觉地图的参与者可以更准确地找到作为任务设置的特定地标，并且独自到达目的地时迷路的频率降低。由 3D 点、线和面部分组成的触觉地图可用作 O&M 训练的辅助工具，因为它们具有较高的触觉可读性，并且可以提供视障人士所需的环境信息。
