Abstract
In the framework of our Reactive Virtual Trainer (RVT) project, we are developing an Intelligent Virtual Agent (IVA) capable to act similarly to a real trainer. Besides presenting the physical exercises to be performed, she keeps an eye on the user. She provides feedback whenever appropriate, to introduce and structure the exercises, to make sure that the exercises are performed correctly, and also to motivate the user. In this paper we talk about the corpora we collected, serving a basis to model repetitive exercises on high level. Then we discuss in detail how the actual performance of the user is compared to what he should be doing, what strategy is used to provide feedback, and how it is generated. We provide preliminary feedback from users and outline further work.
