The ability of taking responsible decisions concerning eating depends on the eating context. This paper considers users of university canteen environments. It outlines the GAPH project and system for informing canteen users about their eating choices, and the effects of choices on their diet. The main component of the system is a tangible solution: the smart GAPH tray. The paper presents the design approach for rapidly deploying tray prototypes, and for assessing them in their natural context. It focuses on the most recent study concerning end users’ interaction with the GAPH tray, and reflects over its results also in terms of the chosen design approach for tangibles for novel contexts. © Springer International Publishing AG 2017.
