In virtual reality the navigation task can generate motion sickness also called simulator sickness or cyber-sickness. This in mainly due to the lack of sensory feedbacks during the task. The presented work aims at studying proprioceptive vibrations for improving the navigation task, decreasing simulator sickness and improving the sense of presence. In this study, proprioceptive vibrations are used to stimulate the lower gluteus maximus muscles during the avatar displacement in the virtual world. The experiment shows the impact of proprioceptive vibrations on navigation task.
