This paper proposes the usage of an Embodied Conversational Agent (ECA) as user interface for achieving structured tasks seamlessly. Specifically, we present the so called METO Agent, a Motivated and Emotional Task-Oriented ECA that is represented in a 3D Virtual Scene, is able to engage in a task oriented conversation with a person in natural language and by expressing different facial expressions and gestures. Our ECA is endowed with personality traits and has the need of getting attention from the user. Along the paper we refer to Virtual Pitonisa, an ECA we have deployed as a METO Agent that represents a real fortune-teller.
