Abstract

Purpose: This study aimed to evaluate the perception and degree of satisfaction of blind individuals regarding an electronic cane prototype with a wearable haptic interface.

Methods: Two scenarios with different obstacles were created to conduct tests with the canes (the user's cane and the prototype one). The perception and satisfaction of participants regarding the electronic cane were assessed using a questionnaire, the number of collisions during the tests, and the time each individual took to complete the course in each scenario.

Results: Ten blind individuals who used the white cane participated in this study. Eight were males, and two were females. Their age ranged from 23 to 43 (average 32.3 ± 7.13 years and median 32 years). There was a tendency for fewer collisions with ground obstacles when the electronic cane was used than when the white cane was used. However, there was no statistically significant difference between the number of collisions and the course completion time in each scenario with either canes tested.

Conclusion: Overall, the perception and satisfaction of individuals regarding the prototype used were positive.

盲人对带有可穿戴触觉装置的电子手杖原型的感知和满意度。

目的：本研究旨在评估盲人对带有可穿戴触觉界面的电子手杖原型的感知和满意程度：方法：为了对手杖（用户的手杖和原型手杖）进行测试，研究人员创建了两个具有不同障碍的场景。结果：10 位使用白手杖的盲人在测试中遇到了不同的障碍物：十名使用白色手杖的盲人参加了这项研究。结果：10 名使用白手杖的盲人参加了此次研究，其中 8 人为男性，2 人为女性。他们的年龄从 23 岁到 43 岁不等（平均 32.3 ± 7.13 岁，中位数 32 岁）。与使用白色手杖相比，使用电子手杖时与地面障碍物发生碰撞的次数更少。然而，在每个测试场景中，两种手杖的碰撞次数和完成路线时间在统计学上没有显著差异：总的来说，个人对所使用原型的感知和满意度都是积极的。
