We consider large sensor networks where the cost of collecting data from the network nodes to the data gathering sink is critical.~We propose several algorithms that use limited local communication and distributed signal processing to make communication mo ...
This document presents a review on gestures for multi-modal interfaces and focus on hand gestures. It first introduces the role that the gesture modality plays in human communication. It then describes different types of gestures. Finally, it gives an over ...
This paper reports on four experimental studies concerning regard to how people use space so as to solve problems collaboratively in virtual environments. Prior to presenting the results, it summarizes the wide range of literature concerning social uses of ...
Group communication provides one-to-many communication primitives that simplify the development of highly available services. Despite advances in research and numerous prototypes, group communication stays confined to small niches. To facilitate the accept ...
This communication describes the multi-modal VidTIMIT database, which can be useful for research involving mono- or multi-modal speech recognition or person authentication. It is comprised of video and corresponding audio recordings of 43 volunteers, recit ...
The present communication is based on the research undertaken by the author and whose principal results are detailed in its thesis entitled « Choice of alternatives of road infrastructures : multicriteria methods » like on the prospects offered by this one ...
The Karhunen-Loeve transform is a key element of many signal processing tasks, including classification and compression. In this paper, we consider distributed signal processing scenarios with limited communication between correlated sources, and we invest ...
Explicit communication semantics are often considered essential for rich interaction between heterogeneous automated systems. While extensive work on semantic models has been carried out, much of this work remains to be tested in real open environments. Th ...
Recently it has been observed that communications using chaos show best performance if the information production related to the chaos in the transmitter is controlled and used for the payload of the communication \cite{Schimming:Nolta:2002}. In the case o ...
This paper presents an investigation of three communication schemes which may be used in a distributed robotic system, two based on implicit forms of communication (mechanical interaction and vision) and one on an explicit form of communication (infrared s ...
