thus, according to the rules of perception, to the areas with particularly strong
potential to produce visual attention.
The second method aims to analyze the intensity of colour contrasts, which were also
identified as attention-directing factors in empirical studies of perception. In order to
do this I propose to use an algorithm based on the Voronoi diagram, which takes a
predetermined area in which is located a series of given points and then divides the
area into regions of colour. These constructed regions have the special quality that
every point within each region is closer to its own centre than to all the other regions’
centres. Once the “voronoi-regions” are created, the tessellation of these regions then
creates the final overlay. This process is then repeated 20 times. The result of the
process is the creation of a colour diagram, within which the points of specific colour
intensity are stressed. 12
4. Conclusion
In the context of this paper, the visually explorative reconstruction of the formal
structure of journal covers aims to analyze the elements controlling attention within
the evaluated material. This process results in an understanding of the production and
control of visual attention in news journal covers, through which the covers are not
only evaluated on the basis of the text or other individual elements carrying meaning,
but instead must be considered seriously in their entirety as visual manifestations. It is
12 A short digression on the subject of diagrammatic reasoning - the Voronoi diagram can be traced
back historically to the 17 th Century and the famous drawing by Descartes depicting the structure of the
universe in “Principia Philosophia”. In this early diagram stars correspond to surrounding areas,
partitioning the solar system into convex regions of influence. The matter in each region then revolves
around its corresponding star.
