본 논문에서는 자이로스코프 센서를 장착한 헤드셋 모델을 소개한다. 이 헤드셋은 교육용으로 설계 되었으며 자이로스코프 센서로 사용자의 위치 및 상태에 따라 장애물에서 송출되는 소리가 다르게 들린다. 사용자의 키 정보를 입력하면 좌우 방향은 물론 상, 하를 인식하여 충돌 반경을 더 세부적으로 조절할 수 있다. 본 논문에서 제안하는 기술을 통하여, 후천적 시각장애인의 경우 '물리적 위험'이 적은 상태에서 지형 정보와 그에 따른 행동을 학습할 수 있을 것이다.

Objective: Physical activity can promote physical and mental well-being. University students are more sedentary recently due to the increased use of computers and other technology. The aim of this study was to investigate differences between immersive 360-degree virtual cycling (IVC) and virtual cycling with head-mounted display (VCHMD) on aerobic capacity and usability in young adults. Design: A crossover study. Methods: Twenty-five university students (13 male, 12 female) participated in this study and completed 2 separate 30 min cycling sessions, such as IVC and VCHMD. In the IVC, participants rode on a stationary cycle while watching curved TV where recorded video was played. To enhance the sense of realism, auditory stimulation was given to the headset, and the gyroscope sensor was used to track the screen as the head moved. In the VCHMD, participants rode on the stationary cycle with head-mounted display, and other conditions were the same as IVC. Participants were assessed the aerobic capacity which included gas analyzer and portable near-infrared spectroscopy, and usability which included simulator sickness questionnaire and system usability scale. Results: Aerobic capacity was significantly difference in the IVC compared with the VCHMD except for the total hemoglobin of right and left rectus femoris and muslce oxygen saturation of left rectus femoris (p<0.05). Cybersickness was less in the IVC than VCHMD and usability was high in the IVC than VCHMD (p<0.05). Conclusions: The findings suggested that IVC might be beneficial exericse to improve aerobic capacity and has lower cybersickness and higher usability than VCHMD.
