The Guts Game is a digital game that uses ingestible sensors to highlight emerging opportunities to design novel bodily experiences.

The Guts Game is a two-player mobile game that uses ingestible sensors to capture players’ gut temperature as core game mechanic. It involves changing one’s gut temperature to outscore an opponent and to win a race.

Unlike most games that are controlled via external controllers, the Guts Game uses an ingestible sensor in the form of a pill, with which the players control the game by varying their gut temperature. This can occur either through food intake of different temperatures, exercising or changing environmental conditions. With the Guts Game, we show that the usage of gut temperature as a game input is feasible and demonstrate that experiencing your body as play, via an ingestible sensor, can be a mesmerizing play experience.
