For this event, we produced two atracBar that could detect the cups laid on the surface and display a different content depending on the coffee in the cup. People were invited to have a drink and play with an interactive content: information about the coffee they were drinking, the different programs developed by Nespresso (environment, etc.) and the company. The interface was very simple to let people navigate no more than two minutes in order en keep a high traffic.
