“…Gauthier et al [19] reported a recent experiment that complements the findings of the present study. In their study, participants were required to acquire route knowledge and find target objects while navigating a real maze, using unaided vision or when wearing night vision goggles.…”

“…The use of aerial perspective is more relevant to pilotage using NVDs. The studies also differed in that in the Gauthier et al [19] study spatial knowledge was acquired through active exploration, whereas in our study it was gained by passive viewing of the scenes. In addition, the use of real night vision goggles confounded the display format with a restricted field of view.…”

“…In addition, the use of real night vision goggles confounded the display format with a restricted field of view. Nonetheless, Gauthier et al [19] found that navigation with NVDs was slower and more error-prone. One possible factor they identified was the associated degradations of visual perception, including loss of colour perception.…”

“…If possible, more realistic, dynamic simulation should be used, based on terrain databases that incorporate the correct reflectances at the wavelengths to which the NVDs are sensitive. In addition, it would be useful to use a headslaved, limited field of view aperture to determine any additional costs due to this factor, as in the study of Gauthier et al [19].…”

An experimental study was carried out to evaluate the combined effect of the absence of colour and the alteration of surface intensities on the recognition of complex scenes. This approach was motivated by the properties of the monochrome imagery of night vision goggles (NVGs), which are a commonly used form of night vision display. Observers were presented with pairs of aerial views of simulated urban scenes (from 400 or 700 ft), taken from viewing angles that differed by 30 deg to ensure that participants could not rely on a viewpoint-dependent cognitive representation of the scene. The observer's task was to decide whether the two scenes were the same, apart from the rotated viewpoint. On catch trials, which were fewer in number, one of the scenes was also mirror reversed. These trials were included to prevent guessing or premature responses. On half the trials, one of the scenes was rendered to simulate the effects of night-vision imagery. The time taken for the observers to confirm the identity of the rotated scenes was measured. There was no effect of differing altitude. When both of the scenes were rendered as daylight imagery, the average time to achieve a match was 34.7 s. When one of the scenes was rendered as NVD-style imagery, the matching time rose to 50.8 s. This effect varied according to the complexity of the scene and the extent to which the scene contained salient coloured features. There were also pronounced differences between observers. These findings suggest that night vision displays may have adverse effects on scene recognition compared to viewing natural-coloured images of the same scenes.

“…Gauthier et al (2008) also focused on night visiong goggles and conducted their landmark search experiment indoors in a small artificial maze where they could set the lighting level similar to half moonlight for the goggle group. The control group participated without night vision goggles in full lighting and performed significantly better in the search, direction estimation and map drawing task.…”

Wayfinding at night in nature is challenging due to limited lighting and a low number of clearly identifiable landmarks. However, several activities in nature involve wayfinding at night, such as rescue services or hiking, but only a few human navigation studies have addressed these conditions. In the present study, we investigate the effects of night on the perception and recall of landmarks along a nature trail using the thinking-aloud and sketch map methods. The results reveal significant differences in the perception between day and night, which mainly originated from a restricted vista at night. In contrast, the landmark recall did not differ between day and night according to the sketch maps, which reflects uniform conceptualisation of the route in both times of day. The observed differences in the perception of landmarks may be applied to the adaptation of geospatial navigation applications that provide real-time wayfinding support, such as interactive maps and navigators, according to the day and night conditions.
