In this paper, we investigated the impact of an egocentric simulated frame of reference, the so-called simulated CAVE, on three type of travel techniques: Steering, Jumping and Sliding. Contrary to suggestions from previous work, no significant differences were found regarding spatial awareness between all techniques with or without the simulated CAVE. Our first results also showed a negative effect of the simulated CAVE on participants' motion sickness for every technique, while confirming that the Jumping is eliciting less motion sickness with or without it.
