Cartographic Design and Usability of Visual Variables for Linear Features

Abstract: This article addresses the measurement and assessment of response times and error rates in map-reading tasks relative to various modes of linear feature visualization. In a between-subject design study, participants completed a set of map-reading tasks generated by approaches to a traffic problem. These entailed quick and correct decoding of graphically represented quantitative and qualitative spatial information. The tasks first involved the decoding of one graphic variable, then of two variables simultaneously. While alternative representations of qualitative information included colour hue and symbol shape, the quantitative information was communicated either through symbol size or colour value. In bivariate tasks, quantitative and qualitative graphical elements were combined in a single display. Individual differences were also examined. The concept of cognitive style partially explains the variability in people’s perception and thinking, describing individual preferences in object representation and problem-solving strategies. The data obtained in the experiment suggest that alternative forms of visualization may have different impacts on performance in map-reading tasks: colour hue and size proved more efficient in communicating information than shape and colour value. Apart from this, it was shown that individual facets of cognitive style may affect task performance, depending on the type of visualization employed.

Colour Contrast in Cartographic Works Using the Principles of Johannes Itten

Abstract: Colour is considered a key means of expression for use in cartographic works This is because colours and the relations among them influence not only the aesthetic impression a map creates but also its overall utility In addition to Newton’s spectral colour theory, today theories with origins in artistic technique are gaining ground in cartography This article introduces J Itten’s colour theory (first published in 1961 in The Art of Colour [Kunst der Farbe]) with special attention given to his concept of seven colour contrasts The article also discusses the suitability and unsuitability of their application in practical cartography, and it contributes original examples employing thematic maps, a discipline with broad possibilities for the application of these inventive methods by today’s mapmakers

Human-computer Interaction in Real 3D and Pseudo-3D Cartographic Visualization: A Comparative Study

Abstract: This chapter summarizes the results of an experiment performed as basic research on the three-dimensional (3D) display of geographical information using two alternative control devices (a Wii remote controller and a mouse). The aim was to explore the influence of a specific type of visualization on the human understanding of depicted geographical information and to discover which type of display—real 3D or pseudo-3D combined with a Wii remote controller and a computer mouse—can be considered better for working with geographical bases. The research was set up as an exploratory analysis and examined the performance of 17 participants. As expected, there were differences in the results between the types of visualization and devices used. Real-3D visualization appeared faster but less suitable for the successful management of tasks than the pseudo-3D visualization. We found no significant differences based on the controlling device when elaborating tasks, but we believe the Wii remote controller device to be a promising device for future studies.

Influence of Graphic Design of Cartographic Symbols on Perception Structure

Abstract: This paper presents a research that was established by interdisciplinary cooperation of psychologists and cartographers. The research is focused on influence of graphic design of map symbols on perceptual structure. Two different sets of map symbols were presented on identical topographic background. Each of the symbol sets was created by different authors and particular symbols vary in size, structure or colour shades. An influence of cognitive style of respondents was observed too.

Cultural Psychology A Once And Future Discipline

Abstract: Thank you very much for reading cultural psychology a once and future discipline. As you may know, people have search hundreds times for their chosen novels like this cultural psychology a once and future discipline, but end up in infectious downloads. Rather than reading a good book with a cup of coffee in the afternoon, instead they are facing with some malicious virus inside their desktop computer.
