This paper addresses how design activities can be supported to evoke nuanced positive emotions through a design case. The topic of nuances of positive emotions and values of differentiating positive emotions in a design process are discussed. The case follows appraisal approach, which implicates that the way people appraise an event determines the type of emotion. Design students created design interventions to specifically elicit one out of ten positive emotions in the context of an airline crew center: anticipation, confidence, energized, inspiration, joy, kindness, pride, relaxation, respect, and sympathy. Three examples are provided to show how the approach has been used to generate design concepts. Reflecting on the design process, nine lessons are outlined, all of which discusses the challenges involved in the approach and how those challenges could be overcome.
