The solar energy departmednt of the ÉS group had a dual need to present its offer : explain the importance of autoconsumption in the return on investment in solar energy projects as well as attract visitors to their booth in fairs and expositions.
Monsieur Cube proposed tan³ (tangible cubes), a intuitive tangible interface. Visitors are invited to place cubes representing electric components on a miniature house. The user thus controls the various parameters involved in the computation of the autoconsumption rate.
