This study investigated usability of graphical icons in the design of human–computer interfaces. A simple additive model of icon acquisition time, including terms for Index of Difficulty, mode of icon array, and log 2 (number of icons) explained 95% of the variance in mean times covering all 36 conditions over 4 laboratory experiments conducted in the… (More)

The role of colour preattentive processing in human-computer interaction task efficiency: a preliminary study. The role of colour preattentive processing in human-computer interaction task efficiency: a preliminary study. Abstract In this paper, results of experimental research on the preattentive mechanism in the human– computer interaction (HCI) were… (More)
The paper is concerned with various ways of analysing the subjective assessment of displaying digital signage content. In the beginning the brief description of the signage system evolution is described and next, the carried out experiment is depicted. The preferences of the 32 subjects were obtained using pairwise comparisons of the designed screen… (More)
In the paper Subjective Overall Workload Assessment (SOWA) method was proposed and described. A computer information system supporting the process of generating appropriate assessment questionnaires and speeding up the analysis of collected data was presented. Next, the SOWA was practically applied for assessing the subjective workload of persons employed… (More)
Scatter plots of facilities on the plane are derived from a heuristic procedure proposed by Drezner. Features of this approach have been investigated. It is shown that scatter plots generated by thèeigenvectors method' could di er in quality. It is shown that this quality depends on the input data structure. By the comparison of eigenvector results with… (More)
