Well-designed mobile, human responsive geographic information technology could improve the lives of millions of mobile smart citizens who daily need to make time critical and societally relevant decisions on the go. We will report on an empirical wayfinding study conducted with Swiss military personnel in an unknown urban environment outdoors. We asked military search and rescue experts to follow a given route using a digital navigation device to reach buildings with people in distress, as fast as possible. We evaluated two mobile map design displays containing either task relevant landmarks highlighted as 2D symbols (orthographic perspective) on the map, or with photorealistic 3D symbols (oblique perspective). We recorded participants’ decision-making activities using mobile electroencephalogram (EEG) and eye tracking during navigation. Participants were also asked to fill in socio-demographic questionnaires and respond to standardized instruments, assessing their background, training, spatial abilities, etc. With this research we aim to contribute to future mobile map designs that guide wayfinders safely and swiftly to their desired location without them losing their innate spatial abilities to orient themselves.
