The Evaluation of Use of Colors in Graphical User-Interfaces in Healthcare

摘要

In this paper, color difference/contrast measures are investigated in reference to results of experiments with the participation of average, color-normal observers and with individuals with deuteranopia. Additionally, a new method for the automatic analysis of color contrast is proposed, which supports designers of graphical user-interfaces in healthcare. The method was verified using the GUI phantom of a vital signs monitor (the configurable, simulated model). Experiments were performed to analyze the role of different color difference measures and the influence of the parameters of the proposed method on final assessment results. It is shown that the proposed method provides reliable information about local color contrast using graphical indication of possible contrast problems. The introduced procedure can be performed automatically providing quantitative and objective evaluation results about the use of color in graphical user interfaces.
