对于视力受损的人来说，白色手杖是获取周围环境信息的重要辅助工具。虽然视障人士应参加定向和行动专家的培训，以学习适当的手杖技术，但专家的人数有限。在我们之前的研究中，我们开发了一个训练系统，使视障者能够使用虚幻的拉动线索学习白色手杖技术。在先前的原型系统中，开发了一种具有内置振动器的手杖抓握型设备，以产生不对称的振动刺激，并根据手杖尖端的位置提供虚幻的拉动提示。虽然原型系统显示出积极的结果，但观察到与有线驱动相关的设备缺乏用户友好性和不切实际的夹持方法相关的问题。本研究开发出一种更实用的白手杖式操作与维护训练装置，为视障者提供独立训练的设想，改善了上述问题。具体而言，该设备是无线的，并具有振动机构的一般甘蔗技术的夹持方法，其有效性证明了评估实验。此外，本文根据与一位活跃的O&M专家的讨论解释了该设备的有用性。评估实验结果表明，该装置的实施，以满足甘蔗培训的要求。
For visually impaired people, a white cane is an important aid for obtaining information about the surrounding environment. Although the visually impaired should attend this training by orientation & mobility (O&M) specialists to learn proper cane technique, the number of specialists is limited. In our previous study, we developed a training system that enabled the visually impaired to learn white cane techniques using illusory pulling cues. In the previous prototype system, a cane grip-type device was developed with a built-in vibrator to generate asymmetric vibration stimuli, and illusory pulling cues were fed according to the position of the cane tip. Although the prototype system showed positive results, issues related to the lack of user-friendliness of the device associated with the wired drive and the impractical gripping method were observed. This study developed a more practical white-cane-type device for O&M training, envisioning independent training for the visually impaired, which improved the above-mentioned issues. Specifically, the device was wireless and had a vibration mechanism for the gripping method of the general cane technique, and its validity was demonstrated by evaluation experiments. In addition, the paper explains the usefulness of the device as per discussion with an active O&M specialist. The results of the evaluation experiments indicated that the devices were implemented to satisfy the requirements for cane training.
