论文摘要
视力障碍的人们在日常生活中遇到许多挑战，尤其是在导航和代表空间方面。购物问题主要是在导航和产品检测水平上解决的，但是很少实现有关对象位置的线索。这项工作提出了使用时空图案的纤维骨架腕带的原型，以帮助视觉障碍的用户在其前面的2D平面中到达对象。一项对十二个视力受试者的试点研究表明，七乘七个目标矩阵中的离散空间并在垂直轴上传达具有离散模式的线索，水平轴上的连续图案是直观有效的设计。
Visually impaired people encounter many challenges in their everyday life, especially when it comes to navigating and representing space. The issue of shopping is addressed mostly on the level of navigation and product detection, but conveying clues about the object position to the user is rarely implemented. This work presents a prototype of vibrotactile wristband using spatiotemporal patterns to help visually impaired users reach an object in the 2D plane in front of them. A pilot study on twelve blindfolded sighted subjects showed that discretizing space in a seven by seven targets matrix and conveying clues with a discrete pattern on the vertical axis and a continuous pattern on the horizontal axis is an intuitive and effective design.
