This study explores the relationship between users' perceptions of a computerized system's beauty and usability. An experiment was conducted using a computerized application as a surrogate for an ATM to test these relationships. Participants rated the system's aesthetics and usability before and after using it. Pre-experimental measures showed strong correlations between perceived aesthetics and usability. Post-experimental measures confirmed this correlation remained intact. A multivariate analysis of covariance revealed that the system's aesthetics significantly affected post-use perceptions of both aesthetics and usability, while actual usability had no such effect. The findings suggest that aesthetic perceptions influence usability perceptions, similar to how physical attractiveness affects perceived personality traits. The study highlights the importance of considering aesthetics in HCI design and its relationship to other design dimensions. The results indicate that users' perceptions of aesthetics and usability are closely linked, and that aesthetic perceptions can influence post-use usability evaluations. The study also found that users' satisfaction with the system was highly correlated with both perceived usability and aesthetics. The findings suggest that aesthetic design plays a significant role in user experience and that further research is needed to understand the underlying processes. The study concludes that aesthetics and usability are closely related in HCI design and that aesthetic considerations should not be overlooked in interface design.This study explores the relationship between users' perceptions of a computerized system's beauty and usability.
