| Popis: | In recent years, the interest and potential applications of pedestrian indoor navigation solutions have significantly increased. Whereas the majority of mobile indoor navigation aid solutions visualize navigationalinformationonmobilescreens,thepresentstudyinvestigatestheeffectivenessofamobile projector-based navigation aid that directly projects navigational information into the environment. A benchmark evaluation of the mobile projector-based indoor navigation interface was carried out, investigating a combination of different navigation devices (mobile projector vs. mobile screen) and navigationinformation(mapvs.arrow)aswellastheimpactofusers’spatialabilities.Resultsshowed the superiority of the mobile screen as a navigation aid and the map as a navigation information type. Especially users with low spatial abilities benefited from this combination in their navigation performanceandacceptance.Potentialapplicationscenariosanddesignimplicationsfornovelindoor navigation interfaces are derived from our findings. RESEARCH HIGHLIGHTS • Experimental benchmark evaluation of a mobile pico projector for pedestrian navigation purposes. • Multidimensional evaluation of the effectiveness of navigation information for pedestrian navigation. • User experience and acceptance of mobile pico projectors. • Inclusion of cognitive user factors (e.g. spatial abilities) and user experiences (e.g. trust, privacy) of mobile navigation aid usage. • Outline of potential application scenarios and design implications for novel indoor navigation interfaces. |
