Is Beauty the new usability attribute? (09 Nov 2005)
There is a lot of talk about beauty in the HCI community (e.g., Norman 2004). However, research tying aesthetics to design is still rather new. (e.g., Kurosu and Kashimura, 1995; Lavie and Tractinsky, 1997; Tractinsky, Katz and Ikar, 2000; Wilson, 2002). These studies demonstrate the "what is beautiful is good" stereotype. That is, they show that the beauty of a product can influence the users' overall impression or general user satisfaction of the product. Think iPod. But how do you measure that?

One of the challenges in measuring the product-emotion relationship is that users are not good at articulating their emotional responses, at least not in a way that's consistent across users. To deal with this challenge design researchers have developed standard measures to help users express their range of emotion by selecting pictures rather than picking words. One such example is Desmet's (in press) Product Emotion Measurement (PrEmo). When using PrEmo, participants' pick the cartoon-like expression that matches their experience. The cartoons dramatically simplify the user's task of representing an abstract emotional response.
