This is interesting… an ice cream vending machine that’s smile-activated. The system recognizes a user’s facial expression and, if they’re smiling, rewards them with free ice cream. It’s a great example of creatively using advanced technology for a brand-relevant experience.
PSFK points out the relationship to Dr. Whippy, an ice cream machine, created by Demitrios Kargotis and shown at the 2009 ARS Electronica festival. That machine analyzed the user’s voice stress and served ice cream as a kind of therapy.
