The scope of this paper is to examine the potential capabilities of embossed printers under the lens of Information Technology (IT). One of the main principles of IT is to manage and deliver information into accessible formats to all users with and without disabilities. The present study investigates the discriminability of lines and squares by…

Bleau, Maxime; Jaiswal, Atul; Holzhey, Peter; Wittich, Walter – SAGE Open, 2022
Additive manufacturing (AM), also known as 3D printing, is a promising tool to produce assistive technology. For instance, individuals with deafblindness (concurrent vision and hearing loss) could benefit from tactile AM-based products as touch may be their main gateway to access information. This study thus aimed to synthesize evidence on the…

Tactile graphics convert visual information into touchable patterns and braille, providing an essential solution for accessible graphics for individuals with visual impairments. Pioneering research advocates for the potential of audio-augmented tactile graphics, which convey complex information through auditory and tactile modalities rather than…

D'Angiulli, Amedeo – Journal of Visual Impairment & Blindness, 2007
In this observational case study, a 13-year old boy, Carlo, who was born completely blind, was invited to explore and identify, a set of raised-line pictures without receiving feedback about the accuracy of his identification. He was then asked to explain, verbally or by drawing, why he believed that the names he suggested accurately identified…

Dulin, David – European Journal of Special Needs Education, 2007
In their specialized schooling, blind children are now frequently presented with raised line figures and maps. However, there is still much to do in evaluating the cognitive effects of training using these displays. The purpose of this research is to determine if the level of expertise in the haptic exploration, and the perception of the raised…

Heller, Morton A.; McCarthy, Melissa; Clark, Ashley – Psicologica: International Journal of Methodology and Experimental Psychology, 2005
This article reviews recent research on perception of tangible pictures in sighted and blind people. Haptic picture naming accuracy is dependent upon familiarity and access to semantic memory, just as in visual recognition. Performance is high when haptic picture recognition tasks do not depend upon semantic memory. Viewpoint matters for the ease…

Speech recognition technology helps people with disabilities interact with computers more easily. People with motor limitations, who cannot use a standard keyboard and mouse, can use their voices to navigate the computer and create documents. The technology is also useful to people with learning disabilities who experience difficulty with spelling…
