Obstacle Avoidance Method in Real Space for Virtual Reality Immersion

Improving virtual reality safety precautions with depth sensing

“…In this study, we used IPQ to measure sense of presence in each experimental condition, which is provided in Appendix B (From Q1 to Q14). Additionally, we were still interested in how much they understood of real-space layout, which was measured by a questionnaire used in Kanamori et al work [29]. This questionnaire aims at evaluating users' sense of distances to obstacles and their confidence levels while walking in the VEs, which can be found in Appendix B (From Q15 to Q27).…”

“…This comment was proved by other researchers' studies as well. Their results have shown that in regard of performance and users' sense of presence, presenting selectively presenting reality which users engaged with was the optimal method, no matter in a standing mode [34] or in a walkingcompatible situation [29]. Apart from that, in Study 2 which only displayed the chair and beanbag, participants did not report they unpleasant feelings.…”

“…We applied the Friedman-test (α = 0.05) for the data analysis [29], and we also used the Bonferroni Method to adjust the p-value, which is 0.0167. The results of four subscales in IPQ are interpreted separately in the following sections.…”

“…Apart from evaluating the immersive effect, respondents evaluated each item after each method at equal intervals via answering a 7-point Likert scales (1 for strongly disagree and 7 for strongly agree) questionnaire to measure their understanding of the physical layout information as well (see Table 9), which was adopted from a previous study [29]. Since the acquired data was also ordinal type, a non-parametric test was used to interpret it.…”

“…Lastly, many previous studies have focused on the real-world interactions while playing VR in the case where users only stand [35], such as grabbing their drink [33], or under the situation where they can naturally walk in the real space [29]. We are thinking about the possibility in a contrary direction where the player can use the virtual objects to interact with the real objects.…”
