To be able to optimize critical components of a system under developmentwithaslittleperceptualerrorsaspossible,userstudiesareconductedthroughoutthewholeprocess.A variety of research methods for diUerent purposes have been provided by standardization bodiessince the 1970s. These methods allow researchers to evaluate the hedonic excellence of a set oftest stimuli. However, a broader view to quality has been taken recently to be able to evaluatequalitybeyonditshedonicexcellencetoobtainagreaterknowledgeaboutperceivedqualityanditssubjectivequalityfactorsthatimpactontheuser.
