Tactile Pictograms Displayed on Pin Array Tablets for Blind Children

Abstract

Illustrated books hold a special place in the development of children. However, few suitable books are available for children with visual impairments. New technologies such as retractable pin tablets make it possible to easily create dynamic illustrations for many books. The illustrations would be based on a set of raised points, representing a shape. In this study, we evaluated the recognition of stimuli achieved with raised dots by 28 sighted and blind children. We have observed that "high resolution" dotted pictograms can be well recognized by blind children and we highlight the importance of the size and proximity of the dots.

Le livre tactile illustré : influence de la technique d’illustration sur la reconnaissance des images par des personnes voyantes et non-voyantes

“…L'analyse statistique comprend donc quatre variables à effet fixe : la variable nombre de points, la variable type d'image, la variable arrondi et la variable similitude. Cette analyse a fait l'objet d'une publication(Mascle, Jouffrais, Kaminski, & Bara, 2020). Il est possible que le fait d'utiliser des petits points puisse diminuer l'effet de certaines variables comme par exemple le nombre de points.…”
