Interacting with socio-emotional agents

In this talk I will present our current work toward endowing virtual agents with socio-emotional capabilities. Through its behaviors, the agent can sustain a conversation, display emotional states as well as show various attitudes and levels of engagement. I will describe methods, based on corpus analysis, crowd-sourcing or motion capture, we are using to enrich its repertoire of multimodal behaviors. These behaviors can be displayed with different qualities and intensities to simulate various communicative intentions and emotional states. We have been developing a platform of humanoid agent able to interact with humans. I will describe an interactive system of socio-emotional agent dialoging with human users.

Using Eyes, Hands, and Brain for 3D Interaction with Virtual Environments

In this talk I will present some of our recent results on 3D interaction with virtual environments, making full use and combining visual, haptic and brain-computer interfaces. We have notably adopted a perception-based approach consisting in taking advantage from knowledge in human perception to improve both the design and the evaluation of our visual and haptic technologies. We have proposed an approach for visuo-haptic rendering that we called “Pseudo-Haptic Feedback” which uses vision to distort haptic perception. We have also studied the use of Brain-Computer Interfaces, which give an access to novel user's input and an incomparable way of interacting with 3D content... "by thought".

Exploiting users preferences and users actions in defining user models for personalised search

In this talk I will address the issue of defining user profiles in the context of personalized search, which is aimed at tailoring the search outcome to the user context. A user profile represents the user interests and preferences that can be captured either explicitly or implicitly. In the lecture I will present an overview of the role the user systems interactions as signals of the users’ interest. Moreover, I will address the issue of formally representing the collected information in a user profile by means of the definition of “personal ontologies”, and I will describe an approach that we have recently developed to this aim.
