Abstract

Digital Signage, a way of advertising or delivering information to viewers through digital displays, has expanded from being just an advertising channel in public places. Recently, it has become widely prevalent in restaurants and retail stores. Despite its wide expansion, digital signage is limited to specific usages and services and the devices it uses are also quite expensive. This study introduces a stick-type digital signage product that operates on Android OS, which addresses all the weaknesses of digital signage with much more reasonable pricing and stable operation. For stability, performance tests were executed on the hardware and applications. The results for hardware performance were extremely promising, as each scenario's maximum performance results, measured by Load Runner programs, reached target indexes. Also, as a result of the usability test, all participants, including non-digital signage system users (novices), were able to easily learn all the tasks. As a result of user satisfaction survey, positive responses were exhibited for ease of learning and usability (LEU), helpfulness and problem solving capabilities (HPSC), affective aspect and multimedia properties (AAMP), commands and minimal memory load (CMML), and control and efficiency (CE).

디스플레이를 활용해 사용자에게 광고 및 정보를 노출 할 수 있는 디지털사이니지는 공공장소에서 광고 채널로서의 역할에서 확장되었다. 최근에는 음식점 및 소매상점으로 널리 확장되어 이용되고 있다. 그러나, 특정 용도에만 맞게 개발되어 있어 확장이 어렵고 단말의 가격 또한 비싸다. 본 연구에서는 이러한 단점을 모두 보완할 수 있는 합리적인 가격과 안정적인 운영성, 높은 확장성을 가진 안드로이드 스틱형 디지털 사이니지 상품을 개발하였다. 안정성 및 사용성을 테스트 하기 위해 H/W 및 App의 Performace Test실시하였다. H/W성능, 시나리오별 최대성능을 Load Runnner로 측정한 결과 모두 목표지수에 도달하였다. 사용성 테스트를 진행한 결과, 피험자들은 비 디지털사이니지 시스템 사용자를 포함해 모두 기능을 쉽게 습득하였다. 설문지를 통해 만족도를 측정하였다. 그 결과 어플리케이션의 학습률 및 사용성(LEU), 유익함 및 문제해결능력(HPSC), 정감적요소와 멀티미디어특성 (AAMP), 제어력 및 단기기억부담의 최소화(CMML), 작동과 효율성(CE)에서 긍정적인 반응을 보였다.
