Evaluation of the usability of symbols indicating a malfunction of automobiles

Abstract

The research presented in this paper refers to the ability of drivers to understand the information presented by symbols, which indicate a certain vehicle malfunction. The testing included 4 symbols, three of which were ISO verified symbols. This study of the usability of symbols on a sample of respondents showed that the understanding of the information presented using symbols is relatively low and ranges between 51% and 65%. By testing statistical hypotheses, it was found that at the population level, these values are even lower. Suggestions have been given that should initiate the improvement of the usability of this type of symbol.
