In an acceleration of 'untact' society during the COVID-19 pandemic, video conferencing platforms have been provided to connect the isolated and to overcome the limit of having interpersonal relationships. While these services brought a great deal of benefits, they also increased the number of people who suffer from additional fatigue from video conferencing. This study, thus, aimed to identify the factors of using video conferencing services and further to examine the relationship between the factors and the users' overall fatigue. Through focus-group interviews and survey, four main factors of fatigue (restriction from untact communication, difficulty of use, background set-ups, discomfort from excessive attention) were identified. This study also found the positive relationships of restriction from untact communication and background set-ups on the users' overall fatigue. The results does not only provide implication on defining new fatigue factors from young generations but also help practitioners and service providers to improve the deficits of services that the real users currently experience.

오늘날 비즈니스의 글로벌화, 사업장의 분산화는 필연적으로 영상회의의 활성화를 가져왔으나, 기 구축된 SD(Standard Definition)급 화질의 영상회의는 실감성 및 장시간 사용시 피로감 등에 따른 이용율 저조로 기대 만큼의 성화를 이루지 못하였다. 또한 기존 영상회의 시스템에서의 dec는 보조적 채널, 시스템 조작과 운영의 복잡성, 낮은 해상도로 인한 표정 및 눈짓 등의 요소 포착이 어려운 한계를 극복하지 못하였고, 기업들은 기업 내부 및 국내외 타기업들과의 협업을 위해 막대한 비용과 시간이 요구되고 있는 실정이다. KT는 기존 영상회의 문제 극복을 위해 서울<->대전 연구소간 전용선 연결, 비용 및 여러 site 확장을 위한 VPN으로의 전환 방안등 최상의 영상회의 구축을 위한 검토를 통해 Full HD실감 화질의 영상회의를 구축하였으며, 향후에는 Full HD 데이터 압축 기술 향상 및 데이터 전송 방안에 대한 더 많은 연구가 필요하다고 판단된다. 본 고에서는 KT에서 구축한 영상회의 사례를 중심으로 기본적인 기술과 구조, 국내외 시장의 현황 및 활용 방안에 대해 논하였다.

With the increase of video conferencing users and the development of technology, the situations where video conferencing is used and the layout of video conferencing interfaces are diversifying. Social anxiety affects video conferencing communication and is closely related to the self-view function, which is characteristic of video conferencing. The self-view function is part of the video conferencing interface that provides a small preview of one's own camera feed. Self-view is known to degrade work performance and cause fatigue; however, it is set as the default function on video conferencing software in a way that users generally prefer. This study used an online survey to study the effect of task orientation, preferred self-view size, and social anxiety on video feedback preference. Participants responded to questions assessing work orientation, social anxiety level, preferred self-view size, and self-view preference. The results showed that preferred self-view size mediates task orientation and video feedback preference. There was no significant difference in the mediating effect of the preferred self-view size according to the degree of social anxiety. These results offer insights into the interactions between users and video conferencing software and provide information that can be useful for designing video conferencing interfaces.
