本文介绍了一种名为ELC （Electronic Long Cane）的辅助技术装置，它是为盲人或视障人士开发的一种行动辅助设备。这种方法包括符合人体工程学的设计，以及在传统长手杖的手柄内嵌入电子设备，通过触觉传播人类的空间和触觉感知。该装置会向腰围以上的障碍物发出信号，并警告可能发生的碰撞。通过自愿盲人对ELC原型进行定性评价。实验结果表明，ELC在检测假想腰围以上的物理障碍方面是有效的，因此有助于盲人更好地感知周围空间。
This paper presents the assistive technology device called ELC (Electronic Long Cane), which was developed as a mobility aid for blind or visual impaired people. This approach comprises an ergonomic design along with an embedded electronics inside the grip of a traditional long cane, which, by mean of haptics, spreads human spatial and tactile perception. The device signalizes obstacles above waistline and warns about potential collisions. Qualitative evaluation of an ELC prototype was carried out by voluntary blind people. The obtained results showed the ELC effectiveness for detecting physical barriers located above of the imaginary waistline, so, contributing to a better perception of the surrounding space by blind people.
