CONTÁTIL: (RE)ADAPTAÇÃO DO MATERIAL DOURADO PARA DEFICIENTES VISUAIS

Resumo

This article is part of a MSc dissertation that developed Contátil, an Assistive Technology that included the (re)adaptation of the Golden Bead Material to the reality of visually impaired children, based on instructional design, accessibility, and usability. Contátil comprises cubes, bars, and plates. Step-engines controlled by an embedded system were used to move blocks. The validation of the technology was based on a qualitative research, using a semistructured interview with 19 Mathematics teachers that specialized in the use of special resources, all of whom were experienced in the teaching of Mathematics to the visually impaired.
