We present a method to synchronize popular music with its lyrics at the stanza level. First we apply an algorithm to segment audio content into harmonically similar and/or contrasting progressions, i.e. the stanzas. We map the stanzas found to a ...

In this paper, a task of human-machine interaction based on speech is presented. The specific task consists on the use and control of a set of home appliances through a turn-based dialogue system. This work focuses on the first part of the dialogue ...

In this paper we propose an approach for checking adaptability property of multimodal User Interfaces (UIs) for systems used in dynamic environments like mobile phones and PDAs. The approach is based on a formal description of both the multimodal ...

Facial expression is a very useful channel for intelligent human computer communication. In this paper we propose a hybrid method to recognize facial expression. Our main contributions in this study are: first, face region is detected by combing ...

Driving assistance systems (DAS) offer support in potentially dangerous situations, especially for unexperienced drivers. Co-operative systems improve their performance by sharing information with each other. One key-enabler for describing and ...

Needs of multimedia systems evolved due to the evolution of their architecture which is now distributed into heterogeneous contexts like the Internet network. A critical issue lies in the fact that they handle, process, and transmit multimedia data. ...

Supporting transparent delivery and convenient use of multimedia content across a wide range of networks and devices is still a challenging task within the multimedia research community; Universal Multimedia Access (UMA) is a vision that has been ...

Producing intelligent environments that are sensitive and responsive to the presence of users and their environment on a large scale is difficult. On one hand, it is technologically very hard to mass produce a device so smart that it is capable of ...

This paper introduces a distributed system for next generation multimedia support in dynamically changing pervasive computing environments. The overall goal is to enhance the experience of mobile users by intelligently adapting the way a service is ...

Designing and developing software for an ambient intelligence (AmI) system involves difficult challenges related to the varied roles of many heterogeneous devices and communication channels, and intelligent user interfaces. Because ambient systems have ...

This paper presents a novel planning approach to assist elders with memory deficit to carry out complex daily activities. The proposed planner uses Markov decision processes (MDPs) in dynamic multi-tasks planning to help memory-impaired elders achieving ...

The vast improvement in classical methods of information access and information retrieval has resulted from the invention of keyword-based search mechanism. Keywords serve as filters for desired information when users search in structured knowledge ...

The main goal of this research is to study the effect of sub-threshold forces on human performance in a haptic-enabled virtual reality system. A multi-modal task similar to Fitts is used to study the effects of the sub-threshold forces on user ...

Three-dimensional virtual environments are becoming more and more important for the inspection of volumetric medical data reconstructed from slices of images coming from Magnetic Resonance Imaging (MRI), Computer Tomography (CT), Positron Emission ...

Energy Efficiency is one of the key issues in Low Rate Wireless Personal Area Networks (LR-WPANs). So far, many research papers have been published on the subject of energy efficiency. However, the throughput in LR-WPAN hasn't been extensively ...

In this work, a design of wireless system for multi-sensors monitoring has been presented. The main purpose of this research is to develop an efficient telemetry system for measuring water pressure and temperature signals. The system reads data from two ...

Bypass-AODV, a local recovery protocol, is proposed to enhance the performance of AODV routing protocol by overcoming several inherited problems such as unnecessary error recovery invocations, newly non-optimal reconstructed routes, high packet drop ...

The Ambient Intelligence paradigm is built upon Ubiquitous Computing (UC), in which the computing devices are embedded in the environment with the purpose of enhancing the human experience at home, workplace/office, learning, health care etc. The UC ...

With wide spread deployment of wireless home networks, management of data across devices is becoming increasingly important. This is especially true for continuous media (audio and video clips) because they are large in size and are streamed at a pre-...

What constitutes relevant information to an individual may vary widely under different contexts. However, previous work on pervasive information systems has mostly focused on context-aware delivery of application-specific information. Such systems are ...

During emergency response situations, decisions have to be made in a timely manner. Multiple entities have to be optimally coordinated and numerous resources must be allocated efficiently, creating a very interesting and challenging technical problem. ...

Provisioning of multimedia services over next generation network and across heterogeneous fixed and mobile networks challenges the developers to define a unified triple play framework solution. However the IP Multimedia Subsystem (IMS) defined by the ...

In mobile peer-to-peer information sharing, binding to - and sharing with - another device uses up computing resources and makes sense only when certain conditions are met. We propose a visual notation and an software tool for mobile devices that ...

Intelligent agents have often been used within intelligent buildings for autonomous actuation of heating, ventilation and air conditioning systems (HVAC) within intelligent buildings. Ubiquitous wireless sensors send environmental data such as ...
