Abstract

In the era of ultra high speed information communication technology represented by Smart phone and Tablet PC, the disable and the aged people came to be in a position of so-called 'relatively weak people' in the field of information communication due to inconvenience of use and difference in information acquisition and processing ability. Thus, a survey was conducted on Smart phone accessibility items based on previous studies of the disabled with crippled disorder, brain lesions, myelopathy and muscular disabilities having more inconvenience relatively in their use of smart phone due to upper limb dysfunctions. Especially, people with upper limb dysfunctions with relatively weak grip had big inconvenience in the conditions of uses requiring actions such as grabbing and rotating the devices, and due to the characteristics of touch screen input method of Smart phone, they had big inconvenience due to a lack of a guidance for keyboard in input. As a result of questionnaires by the type of disability, it turned out that severe myelopathy causes the most inconvenience in using smart phone.

스마트폰과 태블릿 PC로 대표되는 초고속 정보 통신기술시대에 장애인과 노인은 정보 통신 분야에서 이른바 ' 상대적 약자'의 위치에 놓이게 되었다. 이는 스마트폰 등 정보통신기기의 사용에 있어서의 불편함만으로 그치지 않고, ICT 기반의 현대 생활 전반에서 어려움을 유발하고 있는 것으로 나타나고 있다. 이에 뇌병변, 경추, 근육병, 지체장애 등의 상지기능장애를 수반하는 장애유형을 대상으로 스마트폰 접근성 항목에 대한 조사를 진행하였다. 그 결과, 특히 쥐는힘이 상대적으로 약한 상지 기능 장애인은 잡기 및 회전 등의 작업이 필요한 상황에서 큰 불편을 겪고 있는 것으로 나타났으며, 스마트폰의 터치스크린 입력 방식의 특성을 반영한 입력 키보드의 지침 부족하며, 장애 유형에 따른 설문 조사 결과로는, 중증의 척수 장애를 지닌 사용자 집단이 스마트폰 사용에 있어 가장 불편함을 느끼는 것으로 나타났다.
