Camera-mounted quadrotor is currently being utilized as teleoperation robot for search and rescue purposes. However, controlling a quadrotor with proportional R/Cs in remote is not intuitive. Thus, combination with Head Mount Display (HMD) is proposed to increase the ease of maneuverability and sense of immersion. However, it has been reported that the video that contains vibration may induce virtual reality (VR) sickness. Particularly, a quadrotor can largely be disturbed by the wind causing the video to oscillate. Our experiment implies that the large amplitude of vibration and low frequency may have effect on inducing VR sickness. This study investigates the effect of a certain frequency of vibration to VR sickness, and proposes the attitude control of a quadrotor to avoid such movement which may induce sickness.
