'Talkable vegetables'
Vegetables tell their own story in Japan
The in-store promotion tool called ‘Talkable vegetables’, developed by advertising agency Hakuhodo and a specialized lab, makes use of the voltage differential between the moisture of human hands and the vegetables. Touching a tomato works as switch that sets off an audio signal.
The tool was used to inform customers about the produce’s safety and trustworthiness, and the environmental and other farming values under which the vegetables were grown.
The surprise of providing this information through the products themselves helped boost vegetable sales just as surprisingly.
