The presented study aims to examine the effectiveness of spatial pattern and temporal trend recognition on animated choropleth maps. In a controlled laboratory experiment with participants and eye tracking, fifteen animated maps were used to show a different spatial patterns and temporal trends. The participants’ task was to correctly detect the patterns and trends on a choropleth map. The study results show that effective spatial pattern and temporal trend recognition on a choropleth map is related to participants’ visual behavior. Visual attention clustered in the central part of the choropleth map supports effective spatio-temporal relationship recognition. The larger the area covered by the fixation cluster, the higher the probability of correct temporal trend and spatial pattern recognition. However, animated choropleth maps are more suitable for presenting temporal trends than spatial patterns. Understanding the difficulty in the correct recognition of spatio-temporal relationships might be a reason for implementing techniques that support effective visual searches such as highlighting, cartographic redundancy, or interactive tools. For end-users, the presented study reveals the necessity of the application of a specific visual strategy. Focusing on the central part of the map is the most effective strategy for the recognition of spatio-temporal relationships.

The effect of map label language on the visual search of cartographic point symbols / Paweł Cybulski in Cartography and Geographic Information Science, vol 49 n° 3 (May 2022)  

Public [article]  inCartography and Geographic Information Science > vol 49 n° 3 (May 2022) . - pp 189 - 204 Titre : The effect of map label language on the visual search of cartographic point symbols Type de document : Article/Communication Auteurs : Paweł Cybulski, Auteur ; Vassilios Krassanakis, Auteur Année de publication : 2022 Article en page(s) : pp 189 - 204 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] détection de cible [Termes IGN] étiquette [Termes IGN] langage cartographique [Termes IGN] langue [Termes IGN] lecture de carte [Termes IGN] oculométrie [Termes IGN] sémiologie graphique [Termes IGN] symbole graphique [Termes IGN] visualisation cartographique [Vedettes matières IGN] Cartologie Résumé : (auteur) The present study aims to examine how the visual search for cartographic symbols is affected by the language of map labels. More specifically, we explore the influence of native language in the performance of a visual search map task which is referred to target point symbol detection. The main research hypothesis is that the relative position of the target symbols plays a significant role in the visual search process, although labels language impacts reaction time. In a controlled laboratory experiment with 38 participants and eye tracking technology, we used maps with labels in participants’ native language (Polish) and in Chinese, which participants could neither read nor write. We find that the detection of target symbols with Chinese labels is faster when the symbol’s location is peripheral. On the other hand, faster detection of target symbols with labels in participants’ native language favors central location. It turned out that having noticed the target symbol, participants fixated on the native language label. For Chinese labels, having seen the target symbol, participants did not fixate on the label. It also turned out that when participants searched for a target symbol located in the peripheral zone, more visual attention was in this zone. However, when the target symbol’s location was central, the participants’ visual attention focused mostly on the central zone. This confirms the significant role of the location of cartographic symbols in the visual search process.

Spatial visualization of quantitative landscape changes in an industrial region between 1827 and 1883. Case study Katowice, southern Poland / Paweł Cybulski in Journal of maps, vol 16 n° 1 ([02/01/2020])  

Public [article]  inJournal of maps > vol 16 n° 1 [02/01/2020] . - pp 77 - 85 Titre : Spatial visualization of quantitative landscape changes in an industrial region between 1827 and 1883.

The comparison of changes, particularly components of the geographical environment, is based on two time periods – the year 1827 and 1883. Nineteenth-century maps were georeferenced, digitized and a series of thematic spatial visualizations presenting quantitative changes were generated by means of the Geographic Information System (GIS). The scale of the visualization created is 1:100,000 and the area is 16,400 ha. The spatial visualization of quantitative landscape change shows the development of the anthropogenic pressure in the form of settlement areas, raw materials extraction places, roads, and the decrease of natural environments, such as forests, rivers, and water bodies. These changes were caused mainly by the exploration of underground deposits and the rapidly growing population of Upper Silesia.

Cartographic redundancy in reducing change blindness in detecting extreme values in spatio-temporal maps / Paweł Cybulski in ISPRS International journal of geo-information, vol 7 n° 1 (January 2018)  

Public [article]  inISPRS International journal of geo-information > vol 7 n° 1 (January 2018) Titre : Cartographic redundancy in reducing change blindness in detecting extreme values in spatio-temporal maps Type de document : Article/Communication Auteurs : Paweł Cybulski, Auteur ; Beata Medyńska-Gulij, Auteur Année de publication : 2018 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] cécité au changement [Termes IGN] données spatiotemporelles [Termes IGN] redondance de données [Termes IGN] test de performance [Termes IGN] vision [Vedettes matières IGN] Géovisualisation Résumé : (Auteur) The article investigates the possibility of using cartographic redundancy to reduce the change blindness effect on spatio-temporal maps. Unlike in the case of previous research, the authors take a look at various methods of cartographic presentation and modify the visual variables in order to see how those modifications affect the user’s perception of changes on spatio-temporal maps. The study described in the following article was the first attempt at minimizing the change blindness phenomenon by manipulating graphical parameters of cartographic visualization and using various quantitative mapping methods. Research shows that cartographic redundancy is not enough to completely resolve the problem of change blindness; however, it might help reduce it.
