In light of recent attempts to design context-aware mobile phones, this paper contributes by providing findings from a study of mobile phone talk in context. We argue the benefits of investigating empirically the ways in which a place is interactionally constituted as appropriate, or not, for a mobile phone conversation. Based on a study of naturally occurring mobile phone talk, we show how peo...

While changing from a predominantly terminal to an increasingly chronic condition, cancer is still a growing concern. Accompanying this change are new opportunities for technologies to support patients, their caregivers, and clinicians. In this paper, we present an in-depth study of cancer communities. From this exploration, we define and describe the concept of a personal cancer journey. We ex...

With the advent of smart sensing technology, environmental context and user context is widely deployed by the context awareness middleware developers and application developers. This environment leverages to utilize the abundant resources of information. In this paper, we present the principles of context based physiological signal analysis in a ubiquitous VR environment. Ultimate goal of this ...

of the Dissertation A Framework for Pervasive Context Awareness

Context awareness offers a powerful vision that aims to build novel services that adapt to the situation of the user. Context-aware frameworks provide functionalities for gathering data from sensors and for processing this data to interpret the user’s context. This context information is further used to adapt the behavior of services. Adaptation is often performed by applying predefined rules t...

Context aware services have the ability to utilize information about the user’s context and adapt services to a user’s current situation and needs. In this article the authors consider users’ perceptions of the added value of location awareness and presence information in mobile services. The authors use an experimental design, where stimuli comprising specific bundles of mobile services were p...

This study assesses reactions to a wiki enhanced with context-aware features that enable users to learn about people, places, and events in their proximity. In a physically compact enclave such as the urban university in which this wiki is being implemented, context-aware applications can support a hybrid community in which individuals develop and sustain physical and virtual social ties. Parti...

Physical location of users in a multi-agent system is crucial in order to provide them with context -awareness services. A context -aware system can answer to the requests of its users in a more effective way, being able of consider the conditioners that affect them. In this paper we focus in how to provide a FIPA multiagent system with a generic location service for users. We discuss several a...

Bluetooth-technology enables objects to communicate with each other, humans to communicate with each other, and humans to communicate with objects. This paper discusses some possible ways to develop context awareness to enhance the Bluetooth-devices ability to "guess" the groups that Bluetooth (end) user is seeing and using at each moment.

Applications for Wireless Sensor Networks (WSNs) are being spread to areas in which the contextual parameters modeling the environment are changing over the application lifespan. Whereas software adaptation has been identified as an effective approach for addressing context-aware applications, the existing work on WSNs fails to support context-awareness and mostly focuses on developing techniqu...
