Contextual data of learners play a vital role in various e-learning applications in recent years, as learning contexts not only provide learners with context-aware services but also enhance effectiveness. However, various e-learning systems adopt different contextual models (i.e., application-dependent contextual model), and consequently data sharing and system integration are challenging. In t...

Pervasive Computing refers to a seamless and invisible computing environment which provides dynamic, proactive and context-aware services to the user by acquiring context knowledge from the environment and composing available services. In this paper, we demonstrate how heterogeneous Web services can be made interoperable and used to support Pervasive Computing. We present an architecture how a ...

Location based services (LBS) are a specific instance of a broader class of Internet services that are predicted to become popular in a near future: context-aware services. The privacy concerns that LBS have raised are likely to become even more serious when several context data, other than location and time, are sent to service providers as part of an Internet request. This paper provides a cl...

In recent years there has been research on context-aware mobile services that have supported e.g. making appropriate calls, being aware of others, and going on a guided tour. However, there is a lack of user studies that could show that others than engineers and researchers themselves need those services. Therefore, in this paper we will present the results of an observational study on teenage ...

This article presents an approach to context-aware services for “smart buildings” based on Web and Semantic Web techniques. The services striven for are first described, then their realization using Web and Semantic Web services is explained. Finally, advantages of the approach are stressed.

Providing context-aware Web services is an adaptive process of delivering contextually matched Web services to meet service requesters’ needs. We define the term ‘‘context’’ from two perspectives: one from service requesters; and the other from Web services. From the former perspective, context is defined as the surrounding environment affecting requesters’ services discovery and access, such a...

Several studies have reported on interaction challenges users face when confronted with proactive contextaware technologies that take actions on their behalf. To address these challenges, techniques have been proposed to improve intelligibility (understanding) of and control over context-aware systems for end-users. Proactive context-aware systems have not only been featured in several smart ho...

Dynamic context aware systems need highly flexible privacy protection mechanisms. We describe an extension to an existing RBAC-based mechanism that utilises a dynamic measure of invasiveness to determine whether contextual information should be released.
