Evaluating color deficiency simulation and daltonization methods through visual search and sample-to-match: SaMSEM and ViSDEM

Abstract

ABSTRACT Color de cient people might be confronted with minor diculties when navigating through daily life, for examplewhen reading websites or media, navigating with maps, retrieving information from public transport schedulesand others. Color de ciency simulation and daltonization methods have been proposed to better understandproblems of color de cient individuals and to improve color displays for their use. However, it remains unclearwhether these color \prosthetic methods really work and how well they improve the performance of color-de cient individuals. We introduce here two methods to evaluate color de ciency simulation and daltonizationmethods based on behavioral experiments that are widely used in the eld of psychology. Firstly, we propose aSample-to-Match Simulation Evaluation Method (SaMSEM); secondly, we propose a Visual Search Daltoniza-tion Evaluation Method (ViSDEM). Both methods can be used to validate and allow the generalization of thesimulation and daltonization methods related to color de ciency. We showed that both the response times (RT)and the accuracy of SaMSEM can be used as an indicator of the success of color de ciency simulation methodsand that performance in the ViSDEM can be used as an indicator for the ecacy of color de ciency daltonizationmethods. In future work, we will include comparison and analysis of di erent color de ciency simulation anddaltonization methods with the help of SaMSEM and ViSDEM.Keywords: sample-to-match, visual search, daltonization, color de ciency simulation, color de ciency, colorimage quality, image enhancement, behavioral experiment, psychology
