Book ChapterDOI
Wearable Assistive Devices for the Blind
TL;DR: The most significant work done in this area is reviewed to present the latest approaches for assisting this population and to understand universal design concepts for the development of wearable assistive devices and systems for the blind.
Proceedings ArticleDOI
A low-cost highly-portable tactile display based on shape memory alloy micro-actuators
TL;DR: A new concept of low-cost, high-resolution, lightweight, compact and highly-portable tactile display based on shape memory alloy (SMA) technology that allows the development of 60 g weight tactile devices of compact dimensions easily carried in the user's hand.
Journal ArticleDOI
An Outdoor Navigation System for Blind Pedestrians Using GPS and Tactile-Foot Feedback
Ramiro Velazquez,Edwige E. Pissaloux,Pedro M. Rodrigo,Miguel Carrasco,Nicola Ivan Giannoccaro,Aime Lay-Ekuakille +5 more
TL;DR: The experimental results showed that users were capable of recognizing with high accuracy the tactile feedback provided to their feet, and the proposed system enhances independent, safe navigation of blind pedestrians and show the potential of tactile-foot stimulation in assistive devices.
Journal ArticleDOI
Tactile Rendering With Shape-Memory-Alloy Pin-Matrix
TL;DR: A novel pin-matrix tactile-display device that exhibits some advantageous features for the blind: low cost, lightweight, compactness, and high portability is presented.
Proceedings ArticleDOI
A shoe-integrated tactile display for directional navigation
TL;DR: Results show that it is possible to exploit podotactile information for navigation in space and that tactile-foot stimulation could be used for a wide number of applications in human-machine interaction.
