In this paper, we propose a viewpoint switching method on HMD action game to realize both low motion sickness and high immersion. The viewpoint switching method is that first-person perspective with high immersion is used as usual, while thirdperson perspective by a fixed camera is used in the act of strenuous action. The proposed method is applied to an original HMD action game and evaluated by comparing to the case with always first-person perspective and always third-person perspective. The result indicates that the degree of motion sickness and immersion was comparable level with the case of first-person perspective.
