Towards Understanding the Design of Playful Gustosonic Experiences with Ice Cream

There is an increasing trend that explores the convergence of digital play and eating to support a playful relationship with food. We note that interactive sound, although prevalent in digital game design, has only received limited attention in this trend. To contribute to an understanding of "playful gustosonic experiences", we present a design and study of a novel capacitive-sensing ice cream cone, "iScream!". In a study with 32 participants, the cone played four different sounds (a roaring, crunchy, giggling, and burping sound in order to explore fantasy facilitation, food congruency, anthropomorphism and bodily response) when eating ice cream. The results are two themes derived from six findings each, which detail how players explored the different auditory interaction possibilities with their eating actions while the sounds in turn modified those eating actions. Based on these findings, we present four design tactics for designers aiming to create playful gustosonic experiences to ultimately facilitate a more playful relationship with food.
