ABSTRACT
The empirical study of aesthetics in Human-Computer Interaction (HCI) is concerned with - among other topics - the relationship between beauty and usability and the general impact of beauty on product choice and use. Specifically, the present paper explores the notion of a "beauty dilemma" - the idea that people discount beauty in a choice situation, although they value it in general (i.e., they are not choosing what makes them happy). We explored this idea in three studies with a total of over 600 participants. Study 1 revealed a reluctance to pay for beauty due to its hedonic nature (i.e., associated with luxury etc.). Study 2 showed that people prefer a more beautiful product, but justify their choice by referring to spurious advantages in usability. Finally, Study 3 revealed that a choice situation which requires a trade-off between beauty and usability, and which offers no further way to justify choosing beauty, leads to a sharp increase in the preference of usability. The underlying reasons for this "beauty dilemma" and further implications are discussed.

The beauty of simplicity
CUU '00: Proceedings on the 2000 conference on Universal UsabilityIn this paper we show how discussion about design quality or even usability is often discussion about aesthetics. First, we introduce some definitions of beauty in aesthetics. Then, we introduce how the beauty of the Web design affects the feeling of ...
Beyond Beauty: Towards a Deeper Understanding of Aesthetics in HCI
CHI EA '21: Extended Abstracts of the 2021 CHI Conference on Human Factors in Computing SystemsThe word aesthetics, as used in Human-Computer Interaction (HCI), tends to refer to visual characteristics of an interface. Furthermore, it is broadly taken to mean beauty, which, while a significant aspect of aesthetics, is not its only concern. ...
Is beautiful really usable? Toward understanding the relation between usability, aesthetics, and affect in HCI
This paper analyzes the relation between usability and aesthetics. In a laboratory study, 80 participants used one of four different versions of the same online shop, differing in interface-aesthetics (low vs. high) and interface-usability (low vs. high)...
