Abstract

Virtual reality content provides users with a high sense of immersion by using HMD devices. However, while wearing the HMD device, it is difficult to determine the user's location or distance from obstacles, resulting in injuries due to physical collisions. In this paper, we propose a reminder module to prevent accidents by notifying the risk of collision with obstacles while wearing the HMD device. The proposed module receives the user's state from the acceleration and gyro sensor and determines the motion that is likely to cause a collision. If there is an obstacle in the expected collision range, a buzzer sounds to the wearer. As a result of the experiment, the accuracy of obstacle detection in the state of wearing the HMD was 86.6% in the 1st stage and 83.3% in the 2nd stage, confirming the performance of the accident prevention reminder.

가상현실 콘텐츠는 HMD기기를 이용하여 사용자에게 높은 몰입감을 제공한다. 그러나 HMD기기의 착용 중에는 사용자의 위치나 장애물과의 거리를 파악하기 어렵기 때문에 물리적 충돌로 인해 상처를 입는 경우가 발생한다. 본 논문에서는 HMD기기의 착용 중에 장애물과의 충돌 위험을 알려 사고를 방지하는 알리미 모듈을 제안한다. 제안하는 모듈은 가속도·자이로 센서로 사용자의 상태를 입력받아 충돌 사고 가능성이 있는 동작을 판별한다. 충돌 예상 범위에 장애물이 있다면 사용자에게 부저로 경고음을 출력한다. 실험 결과, HMD 착용 상태에서 장애물 감지 정확도가 1단계에서 86.6%, 2단계 상황에서 83.3%로 도출되어 사고 방지 알리미의 성능을 확인할 수 있었다.
