지체장애 아동을 위한 컴퓨터 교육실 구축 모델 및 대체접근을 통한 컴퓨터 접근성 향상에 관한 연구

A Study on Improving Computer Accessibility through Alternative Access and Establishing a Model for Computer Education Room for Children with Physical Disabilities

본 연구의 목적은 지체장애 아동들에게 최대한의 컴퓨터에 대한 접근기회를 제공함으로써 컴퓨터 활용도를 높이는 것이다. 이를 위해 7명의 상지 사용 능력이 떨어지는 뇌성마비 아동들의 컴퓨터 교육실 모델을 구축하였다. 그리고 개별적으로 다양한 대체접근방법을 제시함으로써 컴퓨터에 대한 접근가능성과 사용에 대한 효율성을 높여주었다. 중다기초선 설계를 통해 피험자들의 컴퓨터 접근성을 평가하였으며 다양한 대체 입력장치 및 소프트웨어를 적용하였으며 중재로 사용하였다. 그 결과 대체입력 장치 및 소프트웨어를 사용한 피험자가 표준기보드를 사용한 경우보다 키보드 타이핑 속도와 정확도가 대체적으로 향상되었다. 마우스 또한 대체마우스 장치 또는 소프트웨어적으로 접근을 한 피험자가 표준 마우스를 사용한 경우보다 마우스 클릭, 더블클릭, 그리고 드래그 및 드롭 능력이 대체적으로 향상되었다.

The purpose of this study was to provide maximal opportunities to access computer so that the children with physical disabilities can utilize computer better. For seven children with cerebral palsy who lack upper limb control, a model for computer education room was established. In addition, through providing various types of alternative access methods for each individual, subjects increased accessibility and effective usage of computer. A multiple baseline design across individuals was used in order to assess the computer accessibility and various types of adaptive input devices and software were applied and used as the intervention. As a result, the speed and the accuracy of subjects who used adaptive input device and software performed better than the standard input method. Subjects who used adaptive mouse or software performed better than the standard mouse in terms of ability to click, double click and drag-and-drop.
