Context Information vs . Sensor Information : A Model for Categorizing Context in Context-Aware Mobile Computing

  title={Context Information vs . Sensor Information : A Model for Categorizing Context in Context-Aware Mobile Computing},
  author={Louise Barkhuus},
Context-aware computing proposes technology that adapts according to the user’s situation and environment. Within mobile collaborative work the situation is viewed as an important factor, here context-awareness attempts to facilitate coordination in several ways. Although much research has been conducted, context-awareness is still defined very differently. Besides differing in definitions of context, most research fails to separate between complex context information and precise sensor…

    The Knowledge Engineering Review
  • 2004
An approach encourages a high-level of abstraction for representing and reasoning with situations, and supports building context-aware systems incrementally by providing modularity and separation of concerns.
Context Information in Mobile Telephony
It is concluded that context information should be defined for the area in which the researcher is present instead of attempting to provide an overall definition of context.
Is Context-Aware Computing Taking Control away from the User? Three Levels of Interactivity Examined
This study shows that users feel less in control when using either passive or active context-aware applications than when personalizing their own applications, and concludes that people are willing to give up partial control if the reward in usefulness is great enough.
Rover: Architectural Support for Exposing and Using Context
This dissertation examines two topics: context and the design of a context-aware platform and describes fundamental types of context associated with every piece of information and discusses issues which may occur when implementing a system which utilizes context.
Introducing Context-Aware Features into Everyday Mobile Applications
The approach of introducing context-awareness into everyday applications to make them more easy-to-use aims in shortening both the learning curve when introducing new technology to end-users and prototype development time, as well as results in more reliable prototypes.
Dynamic trust model based on contexts-aware computing
The definition of context-aware and trust is presented, and the trust computation including directed and undirected trustworthiness depending on context is given, which can offer enhanced and more flexible security access control.
How to Define the Communication Situation : Context Measures in Present Mobile Telephony
Mobile telephony is rapidly becoming a wide spread mobile technology. The technological possibilities for context-aware features are increasing, although only few services exist in real consumer
Automatic intelligence application for office environment
This paper applied ambient network concept to office environment and showed the automatic intelligence application, which can support central storage controller to process command very efficiently.
Presença: Aplicações Conscientes de Contexto
It’s undeniable the wide spread of mobile devices, from cellphones to laptops, PDAs or handhelds. This devices have the capability of easing everyday’s life tasks, organize schedules, share


A Survey of Context-Aware Mobile Computing Research
This survey of research on context-aware systems and applications looked in depth at the types of context used and models of context information, at systems that support collecting and disseminating context, and at applications that adapt to the changing context.
There is more to context than location
A Conceptual Framework and a Toolkit for Supporting the Rapid Prototyping of Context-Aware Applications
A conceptual framework is presented that separates the acquisition and representation of context from the delivery and reaction to context by a context-aware application, and a toolkit is built that instantiates this conceptual framework and supports the rapid development of a rich space of context- aware applications.
Context-Aware Computing Applications
This paper describes systems that examine and react to an individual's changing context, and describes four catagories of context-aware applications: proximate selection, automatic contextual reconfiguration, contextual information and commands, and contex-triggered actions.
Context-aware applications: from the laboratory to the marketplace
The aim of this article is to factor out a simple class of context-aware applications and make the creation of these as easy as, say, creating Web pages.
Cyberguide: A mobile context‐aware tour guide
The Cyberguide project is presented, in which the authors are building prototypes of a mobile context‐aware tour guide that is used to provide more of the kind of services that they come to expect from a real tour guide.

Disseminating active map information to mobile hosts
An active map service (AMS) is described that supports context-aware computing by providing clients with information about located-objects and how those objects change over time and how that information is disseminated to its clients.
