Abstract

In this paper, we present the results of an empirical study that aims to evaluate the performance of sighted and blind people to discriminate web page structures using vibrotactile feedback. The proposed visuo-tactile substitution system is based on a portable and economical solution that can be used in noisy and public environments. It converts the visual structures of web pages into tactile landscapes that can be explored on any mobile touchscreen device. The light contrasts overflown by the fingers are dynamically captured, sent to a micro-controller, translated into vibrating patterns that vary in intensity, frequency and temperature, and then reproduced by our actuators on the skin at the location defined by the user. The performance of the proposed system is measured in terms of perception of frequency and intensity thresholds and qualitative understanding of the shapes displayed.

摘要

在本文中，我们展示了一项实证研究的结果，该研究旨在评估有视力者和盲人利用振动触觉反馈来辨别网页结构的能力。所提出的视觉 - 触觉替代系统基于一种便携且经济的解决方案，可用于嘈杂和公共环境中。它将网页的视觉结构转换为可在任何移动触摸屏设备上探索的触觉景观。手指划过的光对比度被动态捕捉，发送到微控制器，转换为强度、频率和温度不同的振动模式，然后由我们的致动器在用户指定的位置在皮肤上重现。所提出系统的性能通过频率和强度阈值的感知以及对所显示形状的定性理解来衡量。
