Overview

Yakult's Japanese vending machine was another world first - a smart machine that ties in with Yakult's Japanese heritage and teaches customers Japanaese. For each word correctly pronounced, customers are rewarded with a little bottle of Yakult.

The technology behind the project involved using Natural Language Processing (NLP) and facial recognition to detect customers approaching, engage them, and detect how accurately they pronounced key words, including 'hello', 'good morning', and 'thank you'.

Brief

Yakult wanted to create a unique vending machine that taught customers how to speak Japanese, and rewarded them with a little bottle of Yakult when they managed to pronounce it correctly. Adding to the experience, the machine can detect when customers approach it and start talking to them immediately.

  • Online connectivity
  • Facial recognition
  • Natural Language Processing for Japanese words
  • Temperature monitoring and remote logging
Facial Recognition

In order to make the experience as fluid as possible, customers are automatically detected as they look at and subsequently approach the machine. Once the machine detects the customer's intent to engage, it automatically starts the experience, and the machine begins to speak to the customer, welcoming them, and inviting them to take part.

  • Embedded camera for facial recognition
  • Embedded microphone for speech detection
Interactive Digital Display

The vending machine was a custom build, including a 42'' capacitive touch display, enabling a reactive, intuitive interaction between customers and the display.

All interactivity and machine functionality is remotely managed and can be updated as required.
