In the past, white canes, guide dogs, and guide helpers have served to assist visually impaired people when walking outdoors. However, these assistance methods have various limitations for extended and suitable usage. Therefore, our laboratory herein proposes a route guidance device that signals commands to the end-user by giving a sense of force to the thumb. The guide device is driven on the common plane with two degrees of freedom by using an XY stage with omnidirectional driving gear. The current prototype presents challenges for its practical implementation as a smooth, safe and reliable route guidance system. In this study, we conducted experiments aiming to optimize the combination of the update position of the intermediate target point and the presentation cycle in blindfolded clear-eyed people.

过去，在户外行走时，白手杖，导盲犬和向导帮手曾为视障人士提供帮助。但是，这些辅助方法对于扩展和适当的使用具有各种限制。因此，我们的实验室在此提出一种路线引导装置，其通过给拇指以力感将信号发送给最终用户。通过使用带有全向驱动齿轮的XY平台，可以在两个平面上以两个自由度驱动导向装置。当前的原型对其作为平滑，安全和可靠的路线引导系统的实际实施提出了挑战。在这项研究中，我们进行了旨在优化蒙住眼睛的人中间目标点的更新位置和呈现周期的组合的实验。
