EI-RO, representing the black-hole of food waste, is a tangible user interface that provides the means for people to fully prevent food waste in the household. By providing reminders, knowledge and assistance EI-RO acts as an innovative food management dashboard for perishables. This project challenged me to increase my technical skills. The demonstrator combined interactive moving 'tangible notifications' and a screen to give the user all the info they need to prevent food waste.
