The terms agent, intelligent agent and 3D agent are becoming more and more frequently used in literature. A key issue in the web community is that a web site must be equipped with a virtual agent able to support users in a natural way. Following this trend, we decided to implement scenographic agents mimic intelligent reasoning (SAMIR), a prototype of a(More)
We are developing a new wearable electronic badge that will enable people working in large organizations to communicate , find information, and interact in more efficient and intelligent ways. The badge will perform speech analysis and speech recognition using a microphone and state-of-the-art micro-power electronics. It will be capable of playing audio(More)
In this chapter we introduce Virgilio, a system which supports the construction of non-immersive VR-based visualizations of complex data objects representing the result of a query performed on a multimedia database. Virgilio takes as input the dataset resulting from a query on a generic database, displays attribute values of the dataset on virtual world(More)
In this paper we discuss how metaphors for supporting user interaction with multimedia databases can be automatically generated. The work presented is a further step in the development of Virgilio, a Virtual Reality (VR) based system that has been designed to be a general purpose exploration tool for highly structured data. Virgilio visualizes the results(More)
In this paper we introduce a model, called Expression Generator, which generates facial expressions related to pseudo emotions and behavior of chatterbots, which are characters used as front ends of dialogue systems employed in Web sites. The emotions are articulated as sequences of MPEG-4 compliant facial displays, and visualized in a browser-embedded(More)
We present a design environment which allows the generation, modification, and visual speech animation of 3D cartoon-like faces – Tinky. Our underlying face model is not based on a set of independent parameters that control specific abstract muscle emulations but is directed by a set of objects representing the elements of the face. In order to provide an(More)
This demonstration presents a prototype system in which metaphors for supporting user interaction with multimedia databases are automatically generated. Such a prototype is a further step in the development of Virgilio, a Virtual Reality (VR) based system that has been designed to be a general purpose exploration tool for highly structured data.
