Which of the following sentences is a clear indication of the CONTRIBUTION? “The events and the associated factors are classified in three phases to identify and explain what hygienes and motivators look like for smartphone use and how frequent they are in comparison to other factors that contribute to users’ satisfaction/dissatisfaction. The key significance of this work is to provide data on the relevance of hygienes and motivators in a UX context and to give concrete examples of these factors for smartphone use. Moreover, we investigate the link between Hassenzahl’s [Hassenzahl 2004] concept of pragmatic and hedonic quality and the hygienes’motivator notion. Based on previous discussions in the UX literature, we expect that pragmatic quality can be considered as hygiene and hedonic quality as motivator.”
