This research examined the effects of learning on driving simulation game in virtual reality environment. We tested the difference of presence and learning effects such as learning persistence and learning transfer between general monitor and 3D virtual reality device, Oculus Rift by playtesting experiment. One hundred drivers with a license participated in the experiment of two modes of gaming environment. As a result, the user’s presence was found to be significantly higher in VR than general monitor game. As functional effects of the driving serious game, learning persistence and transfer of learning showed significant differences between two modes. This study validates the effects of virtual reality on learning, as an aspect of serious game function. The results contributes to theoretical and practical application of virtual reality in interactive serious games in the future.

The aim of this study is to verify the effects of user experiences such as present, flow and arousal between game play under 3D virtual environment(VE) and general video game play. For this purpose, Oculus Rift play test experimental treatment methodology was adapted for analysis. As a result, for the present hypothesis between the VE game and general video game, cognitive and present hypotheses were all adopted except for emotional presence, and there was no difference in arousal effect. And, VE game had significant differences in emotional presence, flow concentration effect, flow merging action & awareness and arousal effect compared with general video game. As the study verified that VE game had higher effect in presence effect, sense of realism and user experience of players than general video games through experimental studies, it contributes to elaborate 3D virtual environment game interface design and user experience study.

We carry out 100-GHz band test observations with the newly-constructed KVN 21-m radio telescopes in order to evaluate their performance. The three telescopes have similar performance parameters. The pointing accuracies are about 4" rms for the entire sky. The main beam sizes are about 30" (FWHMs), which is nearly the diffraction limit of the telescopes at the observing frequency (97 GHz). The measured aperture and main-beam efficiencies are about 52% and 46%, respectively, for all three telescopes. The estimated moon efficiency is ~84% for the KVN Tamna telescope. The first sidelobes appear 50" (~1.6 xFWHM) from the main beam centers and the levels are on average -14 dB.

본 연구는 3D 가상현실에서의 운전 시뮬레이션 게임과 일반 모니터를 사용한 비디오 게임의 환경에서 실재감, 몰입, 각성의 사용자 경험이 어떠한 차이를 나타내는지를 비교 실험을 통해 수행하였다. 또한 운전 시뮬레이션 게임의 기능적 효과 측면에서 기능성 효과인 운전태도와 게임성 효과인 정서적 즐거움 그리고 복합적인 효과인 만족도를 비교 분석하였다. 자동차 운전면허를 소지한 초보운전자 남녀 각50명씩 총 100명의 실험 참여자를 선정하여 두 가지 실험 환경에서 운전 시뮬레이션 게임을 플레이테스팅 방법으로 실험을 진행하였다. 연구결과 실재감, 몰입, 각성의 사용자경험이 가상현실 환경에서 더 높은 것으로 나타났으며 게임의 기능적 효과인 운전태도, 정서, 만족도에서도 유의미한 차이를 나타냈다. 이 연구는 기능성게임의 가상현실 적용에 이론적, 실무적 기여를 하고 있다는 점에 의미가 있다.
