초록
이 연구는 시각장애인을 위한 촉지도 개발·제작과 사용교육에 관한 기초자료로 활용될 수 있다는데 의의가 있다. 이 연구를 위해 시각장애대학생 10명과 정안대학생 20명을 실험 대상자로 선정하여 도형개수의 증가와 인지적 상의 회전유무에 따라 두 집단 간에 공간에서의 위치정보를 판단하고 이를 다시 기억·재생하는 능력에 어떠한 차이가 있는지를 알아보았다. 연구결과, 시각장애대학생이 정안대학생 집단보다 전반적인 위치정보 판단 및 재생 과제수행에 대한 정확도가 낮았다. 특히 시각장애대학생 집단은 도형개수가 증가할수록 정확도의 유의미한 감소를 보였으나 인지적 상의 회전유무에 따라서는 정확도에 별 차이가 없었다.
Abstract
Tactile maps are an important wayfinding aid for people with visual impairments. To use a map effectively it is essential to judge and reproduce the locations of tactile maps. So the purpose of this study is to investigate the ability to judge and reproduce a location information between sighted and visually impaired undergraduates. There were thirty participants in experiment: seven undergraduates who were blind, three who had some residual vision and twenty who were normal sighted. Participants were tested for their ability to explore and reproduce a layout of tactile symbols. in the first experiment, participants explored layouts of one, three or four shapes which the then attempted to reproduce. and than in an aligned condition participants reproduced the array from the same position at which they had explored ti. in the second experiment, participants were asked to move 90 degree around the experiment table between exploring and reproducing the layout. The findings of this study confirmed that visual impaired participants generally were less accurate on all the tasks than the sighted. In the further analysis of visual impaired participants, the effect of number of shapes showed that accuracy decreased as the number of shapes increased. But the effect of alignment revealed no difference between the 90 degree rotated condition and the aligned condition.
