While differences in self-reported answers from the presence questionnaire were not significant (realism: t(21.2) = 0.20, p = 0.841, HMD-VR: M = 29.83 ± 8.2, CT: M = 29.08 ± 9.9; possibility to act: t(20.3) = 0.57, p = 0.573, HMD-VR: M = 19.0 ± 4.2, CT: M = 17.83 ± 5.7; possibility to examine: t(19.2) = −1.14, p = 0.269, HMD-VR: M = 11.5 ± 3.1, CT: M = 13.33 ± 4.6; self evaluation of performance: t(21.9) = 0.55, p = 0.586, HMD-VR: M = 9.42 ± 2.2; CT: M = 8.9 ± 2.3), questions addressing the quality of interface approached significance (quality of interface: t(21.2) = 1.95, p = 0.064, HMD-VR: M = 12.92 ± 2.7; CT: M = 10.5 ± 3.3), suggesting that participants in the HMD-VR and CT groups may have felt differences in the HMD-VR versus CT interfaces.
