“…We followed the above-mentioned design principles by adopting the design method proposed in [77]. The design includes two major visual layers: the spatial reference that offers the context for the focal information is in the visual background (base map), while the thematic information is in the visual foreground.…”

Crisis maps play a significant role in emergency responses. Users are challenged to interpret a map rapidly in emergencies, with limited visual information-processing resources and under time pressure. Therefore, cartographic techniques are required to facilitate their map cognition. In this study, we analyzed the exogenous and endogenous disruptions that users needed to overcome when they were reading maps. The analysis results suggested that cartographers’ taking the stressors into consideration could promote the cognitive fit between cartographers and users, improving map cognition and spatial information supply–demand matching. This paper also elaborates the course of map visual information processing and related graphic variables to visual attention attributes. To improve the users’ map cognition in time-critical emergency situations, crisis map design principles and a methodology were proposed. We developed three fire emergency rescue road maps and performed two evaluations to verify the effectiveness of the principles. Our experiments showed that the principles could effectively facilitate the users’ rapid map perception and proper understanding, by reducing their cognitive load, and could improve the quality of the crisis maps to some extent.

“…Recently, appropriate cognitive design principles, a design methodology and a computerised pre-evaluation of attention-guiding GV have been proposed from the neurocognitive perspective. 44,45 To reach the overall goal of releasing the cognitive workload, we need to embed the design of attention-guiding GVinto a neurocognition-driven development process. In this context, a taxonomy of scientifically testable graphical variables for attention-guiding GV constitutes the theoretical basis.…”

It is a delicate task to design suitable geovisualisations that allow users an efficient visual processing of geographic information. In digital era, such a design task is confronted with a three-fold challenge: the ever growing amount of geospatial data at various granularity levels, the diversified applications and the continuously expanding range of display sizes. A geovisualisation system that strives for a high usability must satisfy the crucial prerequisite of immediately directing the user's gaze to the location of relevant geographic information and of easy decidability of the underlying semantic meanings. To this end, the cognitive skill of visual attention contributes to mnemonic and executive processes. Attention is indispensable for the visual selection. It facilitates the relevant information retrieval, processing and storage. On the basis of neurocognitive visual information processing, the paper addresses the interdisciplinary approach of attention-guiding design of geovisualisations with the intention to establish a taxonomy of scientifically testable variables. The authors try to relate attention-guiding attributes with graphical variables that cartographers apply to encode geographic information. The work is driven by the motivation to enhance the efficiency of geovisualisations and to enable a more precise neurocognition-based evaluation of geovisualisations.

It is a delicate task to design suitable geovisualisations that allow users an efficient visual processing of the depicted geographic information. Today, such a design task is subject to three major challenges: the ever growing amount of geospatial data at various levels of detail, the diversified applications of that data, and the continuously expanding range of display sizes. In this work, the aim was to enhance the visualisation of relevant geographic information by focusing on utility and usability issues of designing geographic information representations. The relevance of information as an element of utility and its cognitively adequate visualisation as an element of usability was considered. To enhance utility, irrelevant data was separated from relevant data by implementing relevance as a filter and embodying relevance values as attributes of the selected objects. To represent these relevant objects and the context information design principles were formulated and a design methodology proposed that tends to facilitate a user's attentional capacities when processing geovisualisations. In order to design this attention-guiding geovisualisation, use was made of approaches and findings from relevance theory and cognitive psychology with emphasis on neuroscientific principles. A combination of relevance filtering and a cognitively adequate visualisation improved the overall usefulness of geovisualisations and made a substantial contribution to their practical acceptability. This interdisciplinary approach allowed a more precise and valid evaluation of geovisualisation designs.
