Geometry is a traditionally difficult subject to teach to visually impaired subjects. This paper investigates tools to help blind children learn geometry. An accessible vibro-tactile-based android application has been designed to allow children to make freehand drawings and play with geometry, recognizing common geometric shapes or topological configurations. An initial usability test of the application, performed by a blind researcher, has revealed some limitations of the proposed approach that could soon be overcome thanks to current technological innovation in the mobile world.

Abstract
Geometry is a traditionally difficult subject to teach to visually impaired subjects. This paper investigates tools to help blind children learn geometry. An accessible vibro-tactile-based android application has been designed to allow children to make freehand drawings and play with geometry, recognizing common geometric shapes or topological configurations. An initial usability test of the application, performed by a blind researcher, has revealed some limitations of the proposed approach that could soon be overcome thanks to current technological innovation in the mobile world.File in questo prodotto:
