Feasibility of full immersive virtual reality video game on balance and cybersickness of healthy adolescents

Abstract

Various virtual reality (VR) games with head-mounted displays (HMDs) can provide immersive experiences, but are often accompanied by negative experiences. We investigated the feasibility of immersive virtual reality game on balance and cybersickness in healthy adolescents. This is cross-over design. This study included 11 healthy adolescents. Balance and cybersickness were measured in the following three conditions. First, as a baseline, only balance was measured while no immersive virtual reality game was being played. Second, balance and cybersickness were measured while the participants played an immersive virtual reality game with a fixed background. Third, balance and cybersickness were measured while the participants played an immersive virtual reality game with a moving background. A force plate was used to measure balance, while the Questionnaire (VRSQ) and Simulator Sickness Questionnaire (SSQ) were used to measure cybersickness. Sway velocity and length significantly increased during the game with a moving background compared to baseline and a fixed background game (p < 0.05). VRSQ and SSQ scores significantly increased during the game with a fixed and moving background compared to baseline (p < 0.05) and were significantly higher with use of the moving versus fixed background (p < 0.05). This study demonstrated that playing an immersive virtual reality game with a moving background could negatively affect balance and cybersickness. These results will help to select game contents that can reduce side effects when applying VR HMD to various fields in the future.
