The appraisal structure of interest proposed by Silvia (2005) was used as a theoretical base of this study. He proposed that two appraisal components, novelty-complexity and coping potential, are required to evoke interest. In the exploratory study phase, it is found that experiences of interest take place in passive interaction and active interaction: when people noticed or observed a product, and when they actually explored and used the products. The sub-questions, raised when people appraise novelty-complexity and coping potential were collected during the exploratory study. The exploratory study identified that each interaction type involves different kinds of sub-questions of novelty-complexity appraisal and coping potential appraisal. In various design case studies, function of novelty is generally well established as an important condition for evoking interest. However, it has not yet been studied if coping potential is a key component for eliciting interest in human-product interaction. Based on the collected sub-questions of appraisal components of interest, three prototypes of an interactive music player were designed with the intention to manipulate a level of interest in both passive and active interaction. Three variants of the prototype are made be identically novel, but have different levels of coping potential. The prototypes were tested with 50 participants. The test of prototypes proved that satisfying or violating the sub-questions of the appraisal components can differentiate a level of coping potential and novelty-complexity, and accordingly, it influenced on level of interest. Therefore, design for interest can be approached by activating novelty-complexity and coping potential, and this approach can be reformulated in terms of designing a product that satisfies (or violates) the sub-questions of appraisal components of interest. The test result showed that correlation of coping potential with interest was significant and stable across the prototypes, which means that coping potential is essential for evoking interest. The strongest correlation for interest was with novelty-complexity. Perceived annoyance was inversely proportional to the level of interest and perceived coping potential. It can be interpreted that novelty-complexity is not enough to elicit interest if there is lack of coping potential.
