The hedonic role of icons has been undermined in contemporary human computer interaction research, though users have specifically mentioned the importance of icons while performing aesthetic evaluation of user interfaces. Previous research has also neglected factors like aesthetics and pleasurable interaction while comparing efficiency of same interface elements. In this regard, current study investigates how different types of icons in mobile applications affect the aesthetics and pleasurable interactions of semi-literate users. This study also investigates the extent to which aesthetics and pleasurable interactions affect satisfaction with the process. The study addresses these issues from the theoretical perspectives of metaphor and aesthetics. Significant differences were observed for aesthetics and pleasurable interactions between two different types of icon sets, namely metaphoric and idiomatic. This study suggests that for higher evaluation of aesthetics and pleasurable interaction for semi-literate users, specific icon types are preferred.
