Non-parametric Wilcoxon Matched Pairs tests show that the percentage correct target ID in the Telepresence condition is significantly higher (87.5%) than in both Mono-Joystick (61.5%; p < .05) and Mono-Headtracking (64.6%; p < .005); Mono-Headtracking and MJ do not differ (p = .51). The repeated measures ANOVA on time to target identification indicates a main effect for Human-Robot Interface (F(2,30) = 17.48, p < .001); all Tukey HSD post hoc tests were significant (all p < .05). Time to target identification is shortest for Telepresence (65.0 seconds), followed by Mono-Headtracking (88.8 seconds), and longest for Mono-Joystick (113.5 seconds).
