시각장애인과 정안인 간의 거리판단 능력에 관한 비교연구 = A Comparative Study on Distance Judgements from a Tactile Map Between the Visual Impaired and the Sighted

다국어 초록 (Multilingual Abstract)

Estimating the distance between places when walking through an environment is an important skill for people with visual impairments. Tactile maps can provide useful information about the distance between places in unfamiliar environments, but the distances on the map need to be scaled to estimate distances in the real environment. The purpose of this study is to investigate this skill. There were thirty participants aged 21 to 39 years in experiment: 10 people who were visual impaired and twenty who were normal sighted. They were given a map and asked to place an object along a path in a position which corresponded to that object``s position on the map. The findings of this study confirmed that the visual impaired performed less well than the sighted, relating to the accuracy of estimating distance. For the tendency of estimating distance, the visual impaired tended to estimate both more shorter or more longer as increasing ratio distances, but the sighted tended to estimate more longer continuously.
