Vending machine gives you free ice cream if you smile
Walls introduced a vending machine that would give you a free ice cream but only if you smile. Facial recognition software inside the kiosk detects the emotion of the person standing in front of it and if it registers a big smile then an ice cream is dispensed. The machine takes a photo of you and allows you to upload and share your photo with your friends. The kiosk was developed by the world leading interactive marketing, creative design, & technology services agency - SapientNitro.
