The Anatomy of a Context-Aware Application

by Andy Harter, Andy Hopper, Pete Steggles, Andy Ward, Paul Webster - WIRELESS NETWORKS, VOL , 1999
"... We describe a platform for context-aware computing which enables applications to follow mobile users as they move around a building. The platform is particularly suitable for richly equipped, networked environments. The only item a user is required to carry is a small sensor tag, which identifies th ..."

A survey of context-aware mobile computing research

by Guanling Chen, David Kotz , 2000
"... Context-aware computing is a mobile computing paradigm in which applications can discover and take advantage of contextual information (such as user location, time of day, nearby people and devices, and user activity). Since it was proposed about a decade ago, many researchers have studied this topi ..."

Cyberguide: A Mobile Context-Aware Tour Guide

by Gregory D. Abowd, Christopher G. Atkeson, Jason Hong, Sue Long, Rob Kooper, Mike Pinkerton , 1996
"... Future computing environments will free the user from the constraints of the desktop. Applications for a mobile environment should take advantage of contextual information, suach as position, to offer greater services to the user. In his paper, we present the Cyberguide project, in which we are buil ..."

are building prototypes of a mobile context-aware tour guide. Knowledge of the user's current location, as well as a history of past locations, are used to provide more of the kind of services that we come to expect from a real tour guide. We describe the architecture and features of a variety

A Conceptual Framework and a Toolkit for Supporting the Rapid Prototyping of Context-Aware Applications

by Anind K. Dey, Gregory D. Abowd, Daniel Salber , 2001
"... Computing devices and applications are now used beyond the desktop, in diverse environments, and this trend toward ubiquitous computing is accelerating. One challenge that remains in this emerging research field is the ability to enhance the behavior of any application by informing it of the context ..."

it of the context of its use. By context, we refer to any information that characterizes a situation related to the interaction between humans, applications and the surrounding environment. Context-aware applications promise richer and easier interaction, but the current state of research in this field is still far

A Survey on Context-aware systems

by Matthias Baldauf, Schahram Dustdar - INTERNATIONAL JOURNAL OF AD HOC AND UBIQUITOUS COMPUTING , 2004
"... Context-aware systems offer entirely new opportunities for application developers and for end users by gathering context data and adapting systems behavior accordingly. Especially in combination with mobile devices these mechanisms are of high value and are used to increase usability tremendously. I ..."

The Cricket Location-Support System

by Nissanka B. Priyantha, Anit Chakraborty, Hari Balakrishnan , 2000
"... This paper presents the design, implementation, and evaluation of Cricket, a location-support system for in-building, mobile, locationdependent applications. It allows applications running on mobile and static nodes to learn their physical location by using listeners that hear and analyze informatio ..."

The Active Badge Location System

by Roy Want, Veronica Falcao, Jon Gibbons - ACM Transactions on Information Systems , 1992
"... cation is the `pager system'. In order to locate a person a signal is sent out by a central facility that addresses a particular receiver unit (beeper) and produces an audible signal. In addition, it may display a number to which the called-party should phone back (some systems allow a vocal me ..."

TaintDroid: An Information-Flow Tracking System for Realtime Privacy Monitoring on Smartphones

by William Enck, Landon P. Cox, Jaeyeon Jung, et al. , 2010
"... Today’s smartphone operating systems fail to provide users with adequate control and visibility into how third-party applications use their private data. We present TaintDroid, an efficient, system-wide dynamic taint tracking and analysis system for the popular Android platform that can simultaneous ..."

Pastry: Scalable, distributed object location and routing for large-scale peer-to-peer systems

by Antony Rowstron, Peter Druschel , 2001
"... This paper presents the design and evaluation of Pastry, a scalable, distributed object location and routing scheme for wide-area peer-to-peer applications. Pastry provides application-level routing and object location in a potentially very large overlay network of nodes connected via the Internet. ..."

The Context Toolkit: Aiding the Development of Context-Enabled Applications

by Daniel Salber, Anind K. Dey, Gregory D. Abowd - University of Karlsruhe , 1999
"... Context-enabled applications are just emerging and promise richer interaction by taking environmental context into account. However, they are difficult to build due to their distributed nature and the use of unconventional sensors. The concepts of toolkits and widget libraries in graphical user inte ..."

and the application. We illustrate the concept of context widgets with the beginnings of a widget library we have developed for sensing presence, identity and activity of people and things. We assess the success of our approach with two example context-enabled applications we have built and an existing application
