Abstract

In this paper, we propose visual Impairment descriptions for MPEG-21 digital item adaptation. The proposed visual impairment descriptions include low vision impairment and color vision deficiency. It is symptom-based description so that the description is systematic enough to sufficiently describe user's any kind of visual impairment characteristics and easy enough to describe for any user with visual impairment. In this paper, we performed some experiments with the proposed description in MPEG-21 digital item adaptation. The experiments showed that the proposed description Is effective to adapt visual resources In digital item for users with visual impairment and to give enhanced visual accessibility to them.

본 논문에서는 MPEG-21 디지털아이템 적응변환을 위한 시각 장애 서술자를 제안한다. 제안된 시각 장애 특성 서술자는 사용자가 가질 수 있는 시각 장애 특성인 저시력 장애와 색각 장애 특성을 포함한다. 제안된 서술자는 사용자의 시각 장애 특성을 충분히 서술할 수 있도록 시각 장애 증후 기반의 체계적인 시각 장애 서술 구조를 가지도록 하였고, 사용자가 용이하게 서술할 수 있도록 서술의 용이성 측면도 고려하였다. 본 논문에서는 제안된 서술자의 유용성을 증명하기 위해, 제안된 서술자를 이용하여 MPEG-21 프레임워크 내에서의 디지털아이템을 적응변환 실험을 수행하였다. 실험을 통해, 제안된 시각 장애 서술자가 시각 장애를 가진 사용자에게 향상된 접근성을 제공하기 위한 디지털아이템 적응변환에 유용함을 보일 수 있었다.
