Check-in data and various contextual factors are widely taken into consideration to obtain people’s preferences regarding POIs in existing POI recommendation methods. In psychological effect-based POI recommendations, the memory-based attenuation of people’s preferences with respect to POIs, e.g., the fact that more attention is paid to POIs that were checked in to recently than those visited earlier, is emphasized. However, the memory effect only reflects the changes in an individual’s check-in trajectory and cannot discover the important POIs that dominate their mobility patterns, which are related to the repeat-visit frequency of an individual at a POI. To solve this problem, in this paper, we developed a novel POI recommendation framework using people’s memory-based preferences and POI stickiness, named U-CF-Memory-Stickiness. First, we used the memory-based preference-attenuation mechanism to emphasize personal psychological effects and memory-based preference evolution in human mobility patterns. Second, we took the visiting frequency of POIs into consideration and introduced the concept of POI stickiness to identify the important POIs that reflect the stable interests of an individual with respect to their mobility behavior decisions. Lastly, we incorporated the influence of both memory-based preferences and POI stickiness into a user-based collaborative filtering framework to improve the performance of POI recommendations. The results of the experiments we conducted on a real LBSN dataset demonstrated that our method outperformed other methods.

The position of sound in audiovisual maps: an experimental study of performance in spatial memory / Nils Siepmann in Cartographica, vol 55 n° 2 (Summer 2020)  

Public [article]  inCartographica > vol 55 n° 2 (Summer 2020) . - pp 136 - 150 Titre : The position of sound in audiovisual maps: an experimental study of performance in spatial memory Type de document : Article/Communication Auteurs : Nils Siepmann, Auteur ; Dennis Edler, Auteur ; Julian Keil, Auteur ; et al., Auteur Année de publication : 2020 Article en page(s) : pp 136 - 150 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie numérique [Termes IGN] audiovisuel [Termes IGN] carte cognitive [Termes IGN] communication cartographique [Termes IGN] document sonore [Termes IGN] information géographique [Termes IGN] information sémantique [Termes IGN] mémoire [Termes IGN] multimedia Résumé : (auteur) Digital maps are known as reliable media for communicating spatial information. People use maps to make themselves familiar with new environments and to form cognitive representations of spatial configurations and additional semantic information that are coupled with locational information. Since the mid-1990s, cartographers have explored auditory media as cartographic elements to transfer spatial information. Among the established sound variants used in multimedia cartography, speech recordings are a popular auditory tool to enrich the visual dominance of maps. The impact of auditory elements on human spatial memory has hardly been investigated so far in cartography and spatial cognition. A recent study showed that spoken object names bound to visual location markers affect performance in memory of object locations. Map users tend to make significantly smaller spatial distortion errors in the recall of object locations if these locations are coupled with auditory semantic information (place names). The present study extends this approach by examining possible effects on sound position as cues for spatial memory performance. A monaural condition, where an auditory name is presented in a spatial location corresponding to the object location, is compared with a binaural condition (of no directional cue). The results show that a monaural communication additionally improves spatial memory performance. Interestingly, the semantic information bound to an object location appears to be the driving factor in improving this effect.

Searching for the ‘right’ legend: The impact of legend position on legend decoding in a cartographic memory task / Dennis Edler in Cartographic journal (the), Vol 57 n° 1 (February 2020)  

Public [article]  inCartographic journal (the) > Vol 57 n° 1 (February 2020) . - pp 6 - 17 Titre : Searching for the ‘right’ legend: The impact of legend position on legend decoding in a cartographic memory task Type de document : Article/Communication Auteurs : Dennis Edler, Auteur ; Julian Keil, Auteur ; Marie-Christin Tuller, Auteur ; et al., Auteur Année de publication : 2020 Article en page(s) : pp 6 - 17 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Cartographie numérique [Termes IGN] carte cognitive [Termes IGN] décodage [Termes IGN] légende cartographique [Termes IGN] mémoire [Termes IGN] oculométrie [Termes IGN] placement des écritures [Termes IGN] représentation cognitive Résumé : (auteur) Map legends are key elements of thematic maps and cartographic communication. The question of how to style map legends is a topic which has often been addressed by cartographic academics and practitioners. Nevertheless, the question of where to position a map legend has only hardly been discussed. Principles of cognitive sciences allow the assumption that a legend positioned to the right of a map field can be read and decoded faster than a legend on the left side. This study investigates the impact of legend positioning on legend decoding. It involves an experiment based on a recognition memory paradigm and the registration of eye-movements. The results show that, in less time, a legend positioned to the right of the map field (compared to a left legend) can be decoded faster. The same accuracy of a cognitive representation of geographic space can be achieved in spatial memory.

Perspective switch and spatial knowledge acquisition: effects of age, mental rotation ability and visuospatial memory capacity on route learning in virtual environments with different levels of realism / Ismini E.

Perspective switch between first-person and aerial-views is an important and commonly executed task in navigation; and it is a special case in studying the effects of aging on navigational performance as well, because, reportedly, it is particularly harder for older people. In a controlled experiment, our participants learned a route in first-person view VE, and reproduced what they learned in an aerial-perspective view in immediate and delayed recall stages. To examine the effects of (and interactions between) multiple factors involved in the experiment in relation to the given task, we provide an in-depth investigation of group differences in spatial knowledge acquisition when a perspective switch is required based on age, mental rotation abilities, and visuospatial memory capacity with three VE designs that differ in levels of realism. Our findings based on the recall accuracy of 81 (42 younger, 39 older) participants in sketching tasks demonstrate significant differences across VE types, overall, in favor of our custom-designed VE in this demanding task. Furthermore, we demonstrate that age and visuospatial memory abilities are strong moderating factors, explicitly in this sketching task that requires a perspective switch, irrespective of VE types.

Hexagonal map grids – an experimental study on the performance in memory of object locations / Dennis Edler in Cartography and Geographic Information Science, Vol 46 n° 5 (September 2019)

To create highly accurate and reliable maps, cartographers must be aware of cognitive effects that occur when people process map information. Interdisciplinary research from cognitive psychologists showed that map graphics lead to spatial distortions in human spatial memory. These distortions can influence human orientation capacities. Recently, it was discovered that grid structures overlaid on maps help to correct spatial distortions in cognitive representations of geographic space. Square grids chunk a map into smaller units (regions). They guide map-viewing behavior, and their regular structure helps map users to recall learned locations of objects more accurately. The effects caused by square grids may also occur when overlaying other common kinds of geometries, such as hexagonal structures. The effects of hexagonal grid structures on memory of object locations were investigated in this map-experimental study. The study design is based on a recall-memory-paradigm, an established method of experimental psychology to measure performance in memory. The results show that hexagonal grid patterns can improve the performance.
