Tactile Rendering With Shape-Memory-Alloy Pin-Matrix

This paper presents a novel pin-matrix tactile-display device that exhibits some advantageous features for the blind: low cost, lightweight, compactness, and high portability. The prototype consists of 64 tactile pins actuated by shape memory alloys with 2.6-mm spatial resolution (Braille-like). Unlike existing devices, the full display weighs only 200 g, and its compact dimensions make it easy to carry. A technical overview of the system is presented, as well as preliminary results on shape recognition, to evaluate its performance on tactile rendering.     

À propos de la conception de systèmes d’aide aux déplacements des déficients visuels

This paper aims to contribute to studies related to visual handicap in order to reduce/eliminate it with new technologies. It addresses shortly the main principle of 3D world human perception, the main rules for environmental pertinent data acquisition and their processing. The proposed state of art on blind people travel assisting aids (taa) allow to understand the requirements for new aids design. A few examples of research project show how solution from new information technologies (such as artificial vision, virtual reality, high densityvlsi, tactile systems, GPS, wireless networks, etc) can be integrated in new systems. These examples allow also to determine which concepts should be targeted when designing any new travel assistance for blind people autonomous and safe displacement, and to characterise new devices.
