In recent years, speech recognition technology has reached a level of maturity to play an important role as a key component of conversational interfaces in many applications, including new services developed on portable devices with limited resources like mobile phones and Personal Digital Assistants (PDA). In this context, Automatic Speech Recognition (ASR) systems needs to meet two conditions...

The goal of the work presented in this paper is to design a context-aware recommender system for mobile devices. The approach is based on decentralized, item-based collaborative filtering on Personal Digital Assistants (PDAs). The already implemented system exchanges rating vectors among PDAs, computes local matrices of item similarity and utilizes them to generate recommendations. We then expl...

Numerous studies have revealed that medical errors are responsible for tremendous patient suffering, loss of life, and billions of dollars in costs. Research also suggests that children are at much higher risk of these errors than adults. New information technologies, particularly personal digital assistants (PDAs), are able to provide readily accessible medical information at the point-of-care...

Available professionally designed systems for recording, storing, retrieving, and analyzing patient data (such as treatments delivered, laboratory and pulmonary function test results, ventilator settings, and patient assessments) are prohibitively expensive to many hospitals and clinics. At Tufts-New England Medical Center we designed and implemented a computerized patient data management syste...

Considering the current trends of the development of mobile devices (e.g. mobile phones or embedded hardware) we note that these devices become smaller but provide more functions. Today, it is not unusual to combine a GPS controller with laptops or personal digital assistants. Even mobile phones with integrated GPS chips are available. Therefore, we can use the exact coordinates of mobile devic...

The aim of this article is to present our proposal for an intelligent monitoring of elderly people based on: the agent technology, a decision support system implemented using a description logic based system and Personal Digital Assistants (PDAs). Agents technology allows us to customize the monitoring service and to distribute the global functionality of the system among several agents. We use...

This paper describes an interaction style in virtual environments that allows co-located users to manipulate certain interactive features of virtual environments with 2D or non-inmersive types of input devices. The concept proposes to make interaction accessible to groups of users by mirroring some of the VE interaction characteristics and functionality and making them accessible from other typ...

This paper introduces the Where Are You (WAY) system, a simple, yet effective application for assisting mobile users in the performance of a variety of routine tasks. The WAY system supports the mobile citizen in the location, tracking and rendezvousing with a variety of moving entities. The WAY system seeks to provide such support by deploying a rich collection of appropriate technologies incl...

The present chapter introduces digital library services’ utilization through handheld devices, such as personal digital assistants (PDAs) and smartphones. It argues that handheld devices proliferation justifies the term digital library in terms of anywhere-anytime access, and retrieval and management of information. Furthermore, these devices constitute powerful information harvesting tools tha...
