In this paper, we review different context classification systems that have been used to define elements of context. Although existing classification systems cover various types of context, in the development of context aware applications, only a few types of context have been used. In this work, we aim to build a context classification model based on Activity Theory that provides a basis both ...

Current tools do not provide adequate support to users for handling reminders. The main reason for this is the lack of use of rich context that specifies when a reminder should be presented to its recipient. We describe CybreMinder, a prototype context-aware tool that supports users in sending and receiving reminders that can be associated to richly described situations involving time, place an...

The paper describes the idea of bringing awareness to nomadic users. Based on a discussion of different context models and approaches to model context, several scenarios for awareness in context-aware systems are presented. We describe the combination of a context aware guidance system and an awareness platform to enable awareness for nomadic users about other users that are either in a similar...

Enabling Context-Awareness in Mobile Systems via Multi-Modal Sensing

Social interaction is critical to knowledge building and sharing in online learning. This paper identifies knowledge, social and technical contexts as the three essential elements of the context space for online social interaction, and accordingly proposes a three-dimensional context-awareness (CA) model to support online social interaction, including Awareness to Knowledge Context, Awareness t...

In this paper we present the architecture of a platform with the goal to support social, context-aware and adaptive/persuasive services aimed at stimulating the elderly to stay active/occupied in life. The platform is Webbased and consists of several modules whose main features are presented and discussed in the paper. Author
