IADIS International Conference WWW/Internet 2010The novelty aspect of iPad was predominant in declaring the first impressions of it, and most adjectivescould be classified as motivational or social (strange, stylish, fresh, modern, discovery, motivating, funny). Itis interesting to notice that the novelty sometimes was referred to as “strangeness”, which can be explainedby the fact that both artifacts were taken as a working tool by some participants( 4 ).4.2 DiscussionTable 4.

Examples of identified affordances in the exploratory studyThis physical affordance of the iPad clearly influenced the identification of the perceived andmotivational affordances (which includes expectations): because it is bigger than the iPhone, people tend toexpect more features on it − considered a motivational affordance in a negative way. On the other hand, theaesthetic of iPad was the first most present positive motivational affordance and the natural interaction(feedback of moviment) observed in the perceived affordances also influenced the motivational aspects.The Tablet PC was more associated to their pen based experience (from drawing and writing on paper).Seen as a working tool, it was referred to as “a laptop with something else”. Although considered heavy alsoon first impressions declarations, aspects of fragility appeared as physical affordances. Physical aspects189
