Abstract

This study was conducted to improve the convenience of design of mobile VR devices use in a way binds smart phones. Research on traditional mobile VR devices is insufficient. So the first survey was conducted on users 100 to understand the current status and status of mobile VR devices. As a result, it was found that the satisfaction with the convenience of use was significantly lowered, and countermeasures were needed. Then, a second survey of 30 Heavy Users was conducted to find out specific usability and problems of mobile VR devices. Through this, problems, ease of use, and other opinions of mobile VR devices were found. The survey results were analyzed through the Descriptive Statistics Act, and it was found that improvement was urgent due to low satisfaction with wearing and network. In-depth interviews were conducted with the same respondents. As with the problems derived first, problems such as wearing satisfaction, excessive head weight for long-term use, and lack of content could be found. Based on the previous studies, the focus group interview consisting of 6 experts derived the ease of use evaluation element. It consists of elements that can satisfy the convenience of use of mobile VR devices for creation, wearing satisfaction, network, morphology, learning, and spatiality, and has a total of 26. Using this evaluation elements, it is intended to provide better ease of use to users who will use the mobile VR device.

본 연구는 모바일 폰을 결착하는 방식으로 사용되는 모바일 VR 디바이스의 디자인 사용편의성 향상을 위해 진행되었다. 기존의 모바일 VR 디바이스에 대한 연구는 미비한 실정이며 모바일 VR 디바이스 사용자 100을 대상으로 1차 설문조사를 진행하여 모바일 VR 디바이스의 현황, 실태를 파악하고자 하였다. 그 결과 사용편의성에 대한 만족도가 크게 떨어지는 것으로 나타났으며 이에 대한 대책이 필요한 것으로 나타났다. 그 뒤 30명의 Heavy User를 대상으로 2차 설문조사를 실시하여 구체적인 모바일 VR 디바이스의 사용성과 문제점을 알아보고자 하였다. 이를 통해 모바일 VR 디바이스의 문제점, 모바일 VR 디바이스의 사용편의성, 기타 의견 등을 도출하였다. 설문조사 결과는 기술통계법을 통해 분석하였으며, 착용 만족성과 네트워크에 대한 만족도가 크게 떨어져 개선이 시급한 것으로 나타났다. 또한 2차 설문조사 이후 같은 응답자들로 실시간 비대면 화상을 통한 심층면접을 진행하였다. 심층 면접을 통해 2차 설문조사에서 도출된 문제점과 같이 착용 만족성에 대한 문제와 장시간 이용에 무리한 헤드 무게, 트레킹 방식의 개선, VR 체험시 발열 문제, 컨텐츠 부족 등의 문제점을 발견할 수 있었다. 앞선 연구들을 기반으로 6명의 전문가로 구성된 초점집단인터뷰(Focus Group Interview)를 통해 사용편의성 평가항목을 도출하였다. 조작성, 착용 만족성, 네트워크, 형태성, 학습성, 공간성에 대한 모바일 VR 디바이스의 사용편의성을 충족 할 수 있는 항목으로 구성하였으며 총 26가지이다. 최종적으로 도출된 모바일 VR 디바이스 사용편의성에 대한 평가항목을 이용하여 모바일 VR 디바이스를 이용하게 될 사용자에게 더 나은 사용편의성을 제공하고자 한다.
