To design an easy-to-use interface, pay attention to what users do, not what they say. Self-reported claims are unreliable, as are user speculations about future behavior.

Wang, Xin, Erdelez, Sanda, Alen, Carla, Anderson, Blake, Cao, Hongfei and Shyu, Chi-Ren (2011): Medical image describing behavior: a comparison between an expert and novice. In: Proceedings of the 2011 iConference 2011. pp. 792-793.

This preliminary study, as a part of a broader study about the medical image use by experts and novices, examines the differences in image describing behavior between these two categories of users. Eye tracking technique was used to capture the image users' eye movement on the Area of Interests (AOIs). This study found that a domain expert was capable of employing nine levels of image attributes in the descriptions, while a novice was able to use only six levels. Furthermore, the expert showed stronger capability in expressing the image information needs by generating more image attributes in the descriptions than the novice, especially in terms of employing significantly more high-level (semantic levels) image attributes. We also found that the novice attended to more AOIs on every image than the expert.

Wang, Jiazhen, Erdelez, Sanda and Thome, James (2011): Online consumer information encountering experience for planned purchase and unplanned purchase. In: Proceedings of the 2011 iConference 2011. pp. 794-795.

This paper proposes an integrated model of traditional consumer buying decision process and Information Encountering (IE) model to study online consumer actual consumption. This study uses Poisson Regression to analyze the relationships between three major factors (consumer, product, and situation) and four types of possible online consumption results (planned purchase without IE experience, planned purchase with IE experience, planned purchase accompanied with unplanned purchase, and unplanned purchase only). Additionally, this study also studies the pattern of product information needs in IE episode of unplanned purchase by Confirmatory Factor Analysis.
