Usability of a mood assessment smartphone prototype based on humor appreciation.

Humor appreciation is one of the determinants of individualu0027s mood and can be assessed through jokes. We have developed a functional prototype called Humoris which asks users to select the funniest punchline and register their affective response to the jokes. Based on usersu0027 responses, the application predicts and displays their short-term mood using emoticons. Our smartphone prototype is evaluated using the u0027think-aloudu0027 method with 9 participants. Usability of Humoris was examined by System Usability Scale questionnaire which gave an average score of 79.44 (SD=8.08). Based on our findings, participants liked the application interface as well as the mood prediction but some of them found some jokes difficult to understand.
