What is beautiful is usable

TLDR

The study examined how users’ perceptions of a system’s beauty relate to its perceived usability. Participants used a computer‑based ATM surrogate, and their aesthetic and usability perceptions were measured before and after interaction. Results showed a persistent strong correlation between perceived aesthetics and usability, with aesthetics influencing post‑use perceptions of both dimensions, underscoring the significance of aesthetic design in HCI.

Abstract

An experiment was conducted to test the relationships between users' perceptions of a computerized system's beauty and usability. The experiment used a computerized application as a surrogate for an Automated Teller Machine (ATM). Perceptions were elicited before and after the participants used the system. Pre-experimental measures indicate strong correlations between system's perceived aesthetics and perceived usability. Post-experimental measures indicated that the strong correlation remained intact. A multivariate analysis of covariance revealed that the degree of system's aesthetics affected the post-use perceptions of both aesthetics and usability, whereas the degree of actual usability had no such effect. The results resemble those found by social psychologists regarding the effect of physical attractiveness on the valuation of other personality attributes. The findings stress the importance of studying the aesthetic aspect of human–computer interaction (HCI) design and its relationships to other design dimensions.
