최근 사회적으로 이슈가 되고 있는 소셜 네트워크 서비스 활용하는 시각 장애인의 수가 점차 증가하고 있으나, 시각 장애인들에 대한 배려 및 접근성은 낙제 수준에 머물고 있다. 이는 보편적인 활용성의 측면보다는 일반인만을 대상으로 제작된 것으로 시각장애인이 원활하게 이용하기에 어려움이 존재한다. 본 논문에서는 시각장애인의 SNS 활용을 지원하기 위한 SNS 관리 시스템을 설계하고 구현한다. 제안하는 시스템은 현재 가장 많은 활용도를 보이는 세 개의 SNS의 공통 특성 분석을 통한 통합 포스팅 관리 및 포스팅 공유 기능을 제공하여 개별 관리 도구 개발에서 발생하는 개발 비용을 감소시키는 것이 가능하다. 또한, 수집 데이터를 시각 장애인의 특성을 고려한 인터페이스로 제공함으로써 시각 장애인의 활용성을 극대화 하였다. 뿐만 아니라, 제안하는 시스템은 독립적인 프로그램의 형태로 제공되기 때문에, 기존의 시각 장애인이 보유하고 있는 보조 기기에 탑재하여 활용하는 것이 가능하다.

With the rapid development of Social Network Service and with the diversification of user needs, new types of image-based SNS have emerged. Image-based SNS provides customized service to meet users' specified contents needs that have yet to be satisfied in conventional relation-based SNS like Facebook, leading the trend of service diversification. Unlike text-based SNS that has inconvenient view on a small mobile screen, image-based SNS provides the communication way focused on simple text message and image, and thus the main users of the image-based SNS are young people in their 20s who get accustomed to images, rather than text messages. Accordingly, the functions and roles of SNS UI have varied, and usability has been more important. With the users in their 20s who use image-based SNS, this study tried to look into the usability of the image-based SNS. To do that, heuristic evaluation method was applied to find UI problems. The main factors constituting usability were extracted, and user evaluation method was redesigned. Aside from the satisfaction measurement, this study conducted and analyzed a questionnaire survey with users in their 20s who used actual image-based SNS. This study analyzed usability factors that influenced of image-based SNS users. The analysis results are considered to be used as a fundamental material to improve usability in the process of developing social media service.
