Abstract

With the technological development in the era of the 4th Industrial Revolution, technologies using HMD are being applied in various fields. HMD is especially useful in virtual reality fields such as AR/VR, and is very effective in receiving vivid impressions from users located in remote locations. According to these characteristics, the frequency of using HMD is increasing in the field related to collaboration. However, when HMD is applied to collaboration, communication between experts located in remote locations and workers located in the field is not smooth, causing various problems in terms of usability. In this paper, remote experts and workers in the field use HMD to solve various problems arising from collaboration, design/propose new types of HMD structures and functions that enable more efficient collaboration, and verify their usability using SUS evaluation techniques. As a result of the SUS evaluation, the new type of HMD structure and function proposed in this paper was 86.75points, which is believed to have greatly resolved the restrictions on collaboration and inconvenience in use of the existing HMD structure. In the future, when the HMD structure and design proposed in this paper are actually applied, it is expected that the application technology using HMD will expand rapidly.

약 4차 산업 혁명 시대의 기술 발전에 따라 다양한 분야에서 HMD를 활용하는 기술이 응용되고 있다. HMD는 AR/VR 등의 가상현실 분야에서 특히 유용하게 활용되고 있으며 원격지에 위치한 사용자가 현장의 생생한 감동을 전달받는 데 매우 효과적이다. 이러한 특성에 따라 협업과 관련한 분야에서도 HMD를 활용하는 빈도가 커지고 있다. 그러나 HMD를 협업에 적용 시 원격지에 위치한 전문가와 현장에 위치한 작업자 사이의 의사소통이 원활하지 못하여 사용성 측면의 다양한 문제점을 야기하기도 한다. 본 논문에서는 원격지 전문가와 현장의 작업자가 HMD를 활용하여 협업 시 발생하는 다양한 문제점을 해결하고, 보다 효율적인 협업의 진행이 가능한 새로운 형태의 HMD 구조 및 기능을 설계/제안하며 SUS 평가 기법을 활용하여 사용성을 검증한다. SUS 평가 결과 본 논문에서 제안한 새로운 형태의 HMD 구조 및 기능은 86.75점을 나타내었으며, 이는 기존 HMD 구조가 가지는 협업 시 제약사항, 사용성의 불편함 등을 크게 해소한 것으로 판단된다. 향후 본 논문에서 제안하는 HMD 구조 및 설계가 실질적으로 적용될 시 HMD를 활용한 응용 기술은 급격하게 확장될 것으로 기대된다.
