THE INFLUENCE OF SYMBOL ORIENTATION AND BORDER LINE THICKNESS ON SUBJECTS’ PREFERENCES FOR ICON DESIGN

This study investigates the influence of symbol orientation and border line thickness on subjects' aesthetic preferences for icon design. Iconography, a critical element in user interface design, relies heavily on visual clarity and aesthetic appeal. Not only shape but also colour and colour combinations influence and make more complex icon design. That implies shape and colour have to be investigated both separately and in interaction. By systematically varying the orientation and border line thickness of icons, we aim to understand how these design parameters affect user preferences. A sample of participants was presented with a series of icons, each differing in orientation and border line thickness, and asked to rate their preferences. Obtained results revealed that both orientation and border line thickness noticeably influence user preference. Icons with certain orientations and moderate border line thickness were consistently rated higher in terms of visual appeal and usability. These findings have important implications for designers, suggesting that careful consideration of these variables can enhance user satisfaction and interface effectiveness.
