This paper describes an algorithm to compute lists of people and devices that are physically nearby to a mobile user based on the analysis of signals from existing wireless networks. The system evaluates proximity by classifying the degree of similarity of the Wi-Fi scan data through a statistical Gaussian Mixture Model. It recognizes when the devices are(More)
In this paper, a complete Smart Space architecture and related system prototype is presented; it is able to analyse situations of interest in a given environment and to produce contextual information related to it. Experimental results show that video information plays a major role for what concerns both situation perception and personalized context-aware(More)
The widespread using of Internet creates new ways to distribute software. Currently, software companies are able to sell their software products to customers through direct downloading. This software distribution model can be extended to "rent" software services to customers and charge them based on their usage of the delivered services, but there have not(More)
Ambient Intelligence (AmI) systems aim at augmenting real environments to create Smart Spaces where users are provided with pervasive virtual services. In order to allow users to seamlessly complete their tasks across a multitude of smart devices, and across different physical locations, the AmI infrastructure must be complemented with ubiquitous(More)
Java support the development of software tools that can be downloaded on-demand by users, software tools on-demand. These tools cannot be purchased like products, because they do not reside on the user's machine. Rather, they can be used as " services. " In this paper, we propose a new paying mechanism for Electronic Commerce of software tools-on-demand,(More)
This paper presents a client/server stateless server architecture to implement collaborative data collection by means of several software tools. Each of the tools can be downloaded as needed in an " on demand " fashion. Security and accounting features are supported. An implemented example is shown based on a metric collection problem.
In this paper the complete framework of a software package for real-time animation of 3D facial models according to the MPEG-4 specifications is described. The focus is mainly on the algorithmic solution that has been adopted for scaling the polygon mesh to a level of complexity suited to the specific hw/sw profile of the platform that hosts the decoder.(More)
The This paper describes the complete implementation of a MPEG-4 facial animation decoder. The various adopted solutions are presented with reference to the major technical issues that are involved, namely the 3D interpolation algorithm for face calibration, the mesh deformation algorithm for model animation and the mesh simplification algorithm. The most(More)
In this paper we propose an efficient algorithm for exploiting the Facial Animation Parameter interpolation modality specified by the MPEG-4 standard in order to allow very low bitrate trasmission of the animation parameters. The proposed algorithm is based on a comprehensive analysis of the cross-correlation properties that characterize FAPs, which is here(More)
