1536-1268/02/$17.00 © 2002 IEEE T oday, mobile devices and gadgets come with more than just a cool and cutting-edge design; they come equipped with small brains and a common language, making them smarter and more powerful than ever before. Perhaps they’re a little too smart—after all, they can adapt and morph into each other and become many-in-one super devices. Mobile phones with PDA capabilit...

Volunteered Geographic Information (VGI), or geospatial crowdsourcing, is where citizens (volunteers) contribute data and information about the earth and environment that is explicitly or implicitly georeferenced and then disseminated via collaborative projects such as OpenStreetMap or social media such as Flickr, Twitter, and Facebook. VGI popularity is due in no small part to citizens making ...

AbstractThis paper focus on location privacy in location based services, Location privacy is a particular type of information privacy that can be defined as the ability to prevent others from learning one’s current or past location. Many systems such as GPS implicitly and automatically give its users location privacy. Once user sends his or her current location to the application server, Applic...

The computing environment of the future will be mobile and pervasive, involving a paradigm shift away from the desktop. Inspired by the beginnings of this shift, from desktop to mobile and pervasive computing, this project set out to look at whether mobile and pervasive computers were different to desktop computers. Specifically, its original aim was to investigate the practice of simply scalin...

The main characteristic of devices in a pervasive (or ubiquitous) computing system is their context awareness which allows them to provide proactively adapted services to user and to applications according to the global context. In order to support the development and to ease the implementation of context-aware systems, many architectures were proposed with characteristics related to the applic...

Whereas social networking has become an essential part of computing today, pervasive computing is seen as a key component for future systems. However, these two paradigms are complementary in many respects – the former responsible for communication and interaction between people, the latter focused on interaction with devices and services in the environment surrounding the user. By combining th...

Handheld computers are increasingly being used by hospital workers. With the integration of wireless networks into hospital information systems, handheld computers can provide the basis for a pervasive computing hospital environment; to develop this designers need empirical information to understand how hospital workers interact with information while moving around. To characterise the medical ...

Scientific collaborations are established for a wide variety of tasks for which several communication modes are necessary, including messaging, file-sharing, and collaborative editing. In this position paper, we describe our work on the Pervasive Collaborative Computing Environment (PCCE) which aims to facilitate scientific collaboration within widely distributed environments. The PCCE provides...

This study reports an emerging application of Semantic Web technologies. The Semantic Web has emerged from Knowledge Engineering and Intelligent Agents, and has been primarily aimed at improved Web Search and Web Services. This study has applied this technology to solve important problems in a CORBA-based Pervasive Computing Infrastructure. Pervasive Computing Environments consist of a large nu...

Nowadays Internet-based multimedia learning has been entered into our daily life over various end user devices including mobile phone. Whereas, participating in the classroom and book reading are still major modalities of learning. Pervasive computing technologies will accelerate the progress and help to build a more convenient learning environment for learners. Smart Space technologies can aug...
