Vending Machine Challenge
We wish to address two aspects of vending machine design: the role of the machine in the marketplace via new ideas of
payment systems and customer interface and interaction with the machine itself.
We are currently exploring four aspects of a new interface design involving: a touch-enabled, semi-transparent display;
a ".magic wand" for purchase selection adn information; a PDA interface and, finally, speech recognition.
Many thanks to M&M/Mars for donation and of the research vending machine and Schott Glas for donation of touch-sensitive
glass for the interface. And thanks to both companies for invaluable collaboration.
