FIGURE 7.

Experimental procedure in a specific order: real-world condition (RWC), corresponding virtual reality (VR) and outdoor virtual reality (VR). The experimental conditions were presented in a randomized order. The three conditions consisted of a familiarization period (in orange) and an experimental phase (in blue). The dotted blue line represents the two blocks of 10 pointing trials per condition. During the experimental phase of each condition, feet positions were recorded for each trial to compute gait parameters. Cybersickness and sense of presence were measured at the end of the familiarization period and at the end of the two pointing blocks of each virtual condition. Acceptance was measured at the beginning of the experiment to quantify acceptance before use, and once again, after the second RVC, to quantify their acceptance after use.
