Dejavniki, ki vplivajo na meritve hitrosti branja barvnih spletnih strani

Most of web-based systems use a fashion-driven graphical user interface design which does not necessarily provide the readers with high reading performance of colour variations of text and background. Many studies addressed this problem but none of them succeeded in offering complete and conclusive results in form of reading performance table which could be used in practice. The aim of this paper is to find reasons for these incomplete results. In our research, we firstly analyzed different experiment designs described in the literature and proposals for further research. Consequently, we tried to find an improved design and carried out an experiment involving 270 students who tested 30 web-safe colour combinations. However, our experiment also did not reveal statistically significant differences in reading speed. Therefore the multidimensional scaling (MDS) method was performed to show that the speed of reading cannot be described as a one-dimensional problem.Veliko spletnih sistemov uporablja uporabniški vmesnik, ki je oblikovan na osnovi modnih smernic, ki pa ne upoštevajo vedno tudi berljivost besedila, ki je odvisna od barve le-tega in barve podlage. S tem problemom se je ukvarjalo veliko študij, ki pa niso uspele ponuditi končnih rezultatov v obliki tabele berljivosti, ki bi bila uporabna v praksi. Namen tega članka je najti vzroke za to. Najprej smo analizirali različne oblike preskusov, ki so opisane v literaturi in tudi smernice nadaljnjega raziskovanja. Na osnovi analize smo oblikovali izboljšan preskus in ga izvedli z 270 študenti. Testirali so 30 spletno varnih barvnih kombinacij. Vendar tudi naš preskus ni pripeljal do tabele berljivosti s statistično značilnimi razlikami med barvnimi kombinacijami. Zato smo s statistično metodo MDS analizirali vzroke za to. Ugotovili smo, da tabele berljivosti zaradi praktičnih omejitev pri izvedbi preskusa ni možno določiti oziroma, da berljivosti ni možno obravnavati kot enodimenzionalni problem
