Topic:

*Modeling Virtual Coaches*

The European Horizon-2020 project Council of Coaches aims to develop a 
tool in which virtual embodied coaches form a team of experts that can 
discuss amongst themselves and with the user how the user could improve 
his healthy lifestyle behaviors. The project combines state of the art 
3D Virtual Avatars with language and reasoning technology and applies 
this to the area of lifestyle and behavior change coaching.

The goal of research is to design, implement and evaluate user 
interaction with the team of virtual agents, the council of coaches 
(Home Interface) and one-on-one interaction with a single coach (Mobile 
Interface). In particular it focuses on

1.Modelling coaches with their own specific agenda and behaviour style 
aiming at creating unique social relationships with users.

2.Adapting virtual coaches’ behavior to ensure that user maintains her 
involvement in the relationship with the coaches.

3.Integrating a backchannel model to ensure dynamic turn-taking and 
user’s engagement.

Specific attention will be given to the development of virtual coaches 
with a wide variety of behavioural characteristics and personality 
traits. Several studies have shown how low level features such as 
behaviour expressivity and high level characteristic (e.g. personality 
traits ) affect user’s involvement in their interaction with the virtual 
characters and impact his performances (McRorie et al., 2011) (Paiva et 
al., 2017)). The behavioural model will be based on data analysis from 
corpora collected within the project using machine learning approach.

The work in this research will make use of and build upon the GRETA/VIB 
platform developed at UPMC (Pecune et al., 2014) for multimodal 
behaviour generation and for visualizing virtual coaches.
