Abstract

Although several industrial revolutions and technological developments have provided time for modern people, more than 75% of modern people are currently suffering from the problem of "lack of time". Therefore, in this paper, it was judged that it was necessary to improve the mobile APP service for efficient time management of modern people, and a study was conducted on the development of usability evaluation tools. First, the current status was analyzed through case studies of six time management apps with different purposes, and then usability studies were conducted to establish a total of five evaluation principles with operability, cognition, user suitability, minimization of work errors, and sharing. Based on this, a draft of the time management mobile app usability evaluation item was prepared, and a total of 44 usability evaluation tool items were derived through three Delphi surveys of design experts over 5 years and less than 10 years. As a result, intuitive screen and menu composition and user's perception of content were evaluated as the most important factors, and conclusions such as the need to improve the structure and function of the main content screen for user error prevention and usability were drawn. This study will not only contribute to improving the usability of existing time management mobile apps, but will also be used as a material for designing an integrated time management platform for efficient time management and purpose promotion in the future, and is expected to be used as an academic reference.

수차례의 산업혁명과 기술의 발달로 현대인들에게 시간적 여유로움이 생겼지만 이에 반해 현대인들 중 75% 이상이 '시간부족 현상' 문제를 겪고 있다. 이에 본 논문에서는 현대인들의 효율적인 시간 관리를 위한 모바일 앱(APP) 서비스 개선의 여지가 있다고 판단되어 사용성 평가도구 개발 연구를 진행하였다. 먼저 각 목적이 상이한 시간관리 앱 6개의 사례조사를 통해 현황 및 구조를 분석하였으며, 사용편의성에 관한 선행연구를 진행하여 조작성, 인지성, 사용자적합성, 작업오류의 최소화, 공유성으로 총 5가지의 평가원칙을 정립하였다. 이를 기반으로 시간관리 모바일 앱 사용성 평가항목 초안을 작성하였으며, 이것을 5년 이상, 10년 이하의 디자인 전문가 집단을 대상으로 3차례의 델파이조사를 통해 총 44개의 사용성 평가도구 항목을 도출하였다. 그 결과 직관적인 화면 및 메뉴구성과 사용자의 콘텐츠 인지가 가장 중요한 요소로 평가되었으며, 기능적 측면에서의 사용자의 오류 방지 및 사용성을 위한 메인 콘텐츠 화면의 구조, 기능 개선의 필요성 등의 결론이 도출되었다. 본 연구는 기존 시간관리 모바일 앱 사용성 개선에 기여할 뿐만 아니라 향후 효율적인 시간관리 및 목적 증진을 위한 통합적 시간관리 플랫폼 설계 연구의 자료로 활용될 것이며, 나아가 앱 개발 또는 사용성에 관한 학술적 참고자료로 활용될 수 있기를 기대한다.
