Aesthetics and Usability

Our collaborative work on perceptions of interface aesthetics was among the first attempts to operationalize related constructs and test their impact on usability, and subsequently, the use of a website and/or a wireless data service. Our finding of "cooler" color combinations being preferred over "warmer" ones has been validated by a number of follow-up studies that cite our work, and been used as a key design recommendation by web consultants internationally. We have also found a "golden section" for white space in web interfaces, which is the range between 25-50% of the real estate. Alternatively, less than 25% or more than 50% white space in web interfaces results in user perceptions of clutter and subsequent annoyance or diminished usefulness respectively.
