Simulation and analytical model for evaluating the informativeness of graphical user interfaces
The requirements for software products are becoming increasingly stricter, since their effectiveness determines the performance of users. This, in turn, affects the productivity of the organizations where these users work. The current scientific literature and software market lack tools for assessing the informativeness of graphical user interfaces from the standpoint of increasing the performance of users. Purpose of the work: Development of tools in the form of a simulation and analytical model that would permit an analysis of the informativeness of interfaces and performance prediction of their users during their working day. Methods: To achieve the aim, rules and patterns from such disciplines as visual aesthetics, human-computer interaction, Gestalt psychology, neuroaesthetics, perceptual psychology, and ergonomics were used. In addition, the author’s algorithms and indicators for assessing the informativeness of interfaces, presented in earlier publications, were used. Results: Interface loads that affect the person during the working day when using software products are determined. Their composition in the form of spectra of indicators for assessing the informativeness of interfaces is determined. Analytical models for cognitive, visual, and motor loads affecting users of software products are built. An original formula for assessing user performance in software products is proposed. A simulation and analytical model for assessing the informativeness of interfaces is implemented, allowing real-time tracking of changes in cognitive, visual, and motor loads under changes in the characteristics of user models and interfaces. The model allows automating the process of assessing and comparing interfaces similar in functionality and purpose.
