The Keen Coffee Machine is an intelligent coffee machine interface. The agent follows a task model that adheres to the CEA-2018 standard to guide the user through the steps of entering an optional wand number, selecting their coffee and paying for their coffee. The imaginary wand is a small, portable device that stores saved coffee options and a funds balance. This simplifies selecting the user's everyday coffee and payment.

ANSI/CEA-2018 Task Model:
