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.

我们开发了一种新工具包，可以组装三维（3D）触觉图，以向视力障碍者提供定向和活动性（O＆M）培训。这项研究评估了言语解释与3D触觉地图套件相结合的效果，与仅言语解释的效果相比，它在提高理解，回忆和沿着陌生路线行走方面的效果。3D触觉地图为参与者带来了严重的视觉障碍，并且几乎没有触觉地图的经验，他们可以更好地理解和回忆有关路线和地标的环境信息。使用3D触觉地图的参与者可以更准确地找到设置为任务的特定地标，并且仅到达目的地就迷路的频率就降低了。由3D点，线，
