시각장애학생의 시각자료 활용과 학습을 위한 햅틱디스플레이 기반의 특수교육 보조공학시스템 설계

Abstract

In this study, we designed a special education assistive technology system consisting of Haptic-display providing visual information converted to tactile information and educational contents. To design a special education assistive technology system appropriate for special education environment, we derived system requirements by surveying teachers and visually impaired students, and we also analyzed tactile information perception characteristics of visually impaired students based on in-depth interviewing. In addition, we analyzed current special education resources and special education technology devices, and we designed a new special education technology system appropriate for visually impaired special education environment based on the analysis results. We designed the Haptic-display device and its user interface considering of tactile information perception characteristics of visually impaired students and their requirements, and also designed educational contents producing program that can automatically translate text, equation and visual information to tactile information. We expect that the proposed system can maximize learning efficiency of visually impaired students.
