Correlation analysis was used to carry out the comparison. Values for the tested objective measures were calculated for forty-two web pages already used in a previous study, for which subjective questionnaire scores (classical/expressive and VisA WI) were already available. Results showed significant correlations between many of the tested objective screen layout-based measures and subjective questionnaire-based measures related to order and layout of the screen. These findings suggest that the objective layout-based measures tested in this study can be used for overall assessments of visual aesthetics of websites and particularly for assessing aesthetic aspects related to the classical and the simplicity dimensions of website aesthetics.
Effects of Unity of Form and Symmetry on Visual Aesthetics of Website Interface Design

High levels of unity of form can be achieved by using objects with similar sizes on the screen and/or by reducing number of objects on the screen. Findings of earlier observational studies suggested that effect of unity of form on perceived visual aesthetics of website design was more evident in case of highly symmetrical webpages. The purpose of this study is to verify these findings. An experiment was conducted to systematically study effects of number of objects and number of different sizes of objects on perceived visual aesthetics of website design at high and low levels of symmetry. Perceived aesthetics was assessed using the classical/expressive dimensions. Results showed that both factors have significant effects on perceived visual aesthetics, only at high levels of symmetry and only on the classical dimension.

It is argued that these three elements are the most contributed terms in the model. In the current study, a controlled experiment was designed and conducted to systematically investigate effects of these three elements (balance, unity, and sequence) on the perceived interface aesthetics. Results showed that the three elements have significant effects on the perceived interface aesthetics. Significant interactions were also found among the three elements. A regression model relating the perceived visual aesthetics to the three elements was constructed. When validating the model using standard questionnaire scores of real web pages, high correlations were found between the values computed by the model and scores of questionnaire items related to visual layout of the web pages, indicating that layout-based measures are good at assess...

This framework is concerned with determining what features triggers users' perception of aesthetics and tries to express such features numerically. The goal is to combine their collective effects using mathematical formulas and computational models that would objectively predict perceived visual aesthetics.
Experimental Investigation of Effects of Balance, Unity, and Sequence on Interface and Screen Design Aesthetics

A recent study suggested the use of the elements of balance, unity, and sequence of screen layout as part of a computational model of interface aesthetics. It argued that these three elements are the most contributed terms in the model. In the current study, a controlled experiment was designed and conducted to investigate the effects of these three elements (balance, unity, and sequence) on interface aesthetics. Results confirmed finding of previous researches, the three elements have significant effects on the perceived interface aesthetics. Significant interactions were also found among the three elements. Implications of results and potentials extensions for future work are also discussed.
