Based on an ethnographic study of community road signs, we argue that mobile location aware systems fit somewhat with an abundant practice where private persons make and post signs along the roads. People who live along roads have various reasons, and investigate in various ways, to communicate with passing drivers. Even though these road signs are mostly used for interaction outside of the nei...

When interacting with applications, users are less restrictive in disclosing their personal data than if asked in an application-independent context. On a more general level this behavior is termed as privacy paradox. The creation of privacy awareness can assist users in dealing with contextaware services without harming their privacy unintentionally, thereby addressing the privacy paradox. The...

This chapter introduces intelligent technologies applied in electronic healthcare systems and services. It presents an overview of healthcare technologies that enable the advanced patient data acquisition and management of medical information in electronic health records. The chapter presents the most important patient data classification methods, while special focus is placed on new concepts i...

The context aware systems are often designed and implemented based on a specific scenario with predefined resources. In this paper, we describe a ubiquitous interactin space that supports rapid context-aware applications reflecting the smart interaction space with dynamic resources and provides a programmable interface in integrated development environment (IDE) in .NET framework.

Smart devices have pervaded our society and encouraged lifestyles that depend on them. One of the fundamental requirements for a successful dependency is that the general public be aware of the energy limitations of these devices and to stay in control of energy consumption. In this paper, the authors propose a formal specification method that takes energy into account. They propose two develop...

This paper examines the use of surveys in measuring privacy concerns in ubiquitous computing environments. Two evaluation techniques are used to study the privacy concerns of sharing context information: a paper based survey and in-situ questionnaires. Results from the two techniques differ significantly, suggesting that surveys are not reliable in predicting privacy concerns regarding context-...

Through an iterative design approach, we have proposed and evaluated ways of incorporating user-created information into context-aware systems. We implemented and tested a location-sensitive college campus tour guide called Campus Aware that allows users to annotate physical spaces with text notes. The goal was to provide visitors to the campus with a sense of the activities going on in the env...

Time aware systems claim for an explicit representation of time-related concepts, so that they can be observed and possibly controlled at run-time. The paper identifies a set of architectural abstractions capturing such concepts related to time and classifies the base activities performed by a time aware system. Our proposal has been formalized using two different modeling techniques: UML and P...

Recently there has been an interest in spatially aware systems for pedestrian routing and city exploration, due to the proliferation of smartphones with GPS receivers among the general public. Since GPS readings are noisy, giving good and well-timed route instructions to pedestrians is a challenging problem. This paper describes a spoken-dialogue prototype for pedestrian navigation in Stockholm...

This paper focuses on the relevant information for collecting and presenting contextual information, its effects and impact on the learning interaction cycle, and mechanisms of controlling it. The core principle of the learning interaction cycle is the interaction of learners with their learning environment. Previous research highlights that such interaction is important for the experience and ...
