“…We do not attempt an exhaustive review, focusing instead on three well-known systems that have interesting features: Stick-e Notes, CALAIS, and the Context Toolkit. For brevity, other such context-aware support systems such as CoolTown [5], Gaia [6], and Confab [7] are not discussed here; the interested reader is referred to their references.…”

Abstract. Context-awareness refers to a computing model where application behavior is driven by a continually-changing environment. Mobile computing poses unique challenges to context-sensitive applications and middleware, including the ability to run on resource-poor devices like PDAs and the necessity to limit assumptions about the underlying network. Though middleware exists to provide context-awareness to applications, they have not been designed with the limitations inherent in dynamic mobile environments in mind. This paper discusses a lightweight approach to context-sensitivity that takes into account these considerations. We explore the use of modularization to tailor service discovery policies for specific applications, as well as leveraging existing language constructs for simplifying the creation and aggregation of different context types. We also discuss a Java implementation of these concepts, along with three sample applications that can automatically propagate changes in context to clients running on devices varying from mobile phones to desktop computers.

“…In general, the resulting systems are built around Personal Digital Assistants (PDAs): the Cyberguide [10] is a museum tour guide; CoolTown [8] displays web pages to users depending on their location. These approaches suffer from one major drawback: they force users to carry with them a given electronic device.…”

This paper deals with the design of multimodal information systems in ambient intelligence. Its agent architecture is based on KUP, an alternative to traditional software architecture models for human-computer interaction. The KUP model is accompanied by an algorithm for choosing and instantiating interaction modalities. The model and the algorithm have been implemented in a platform called PRIAM, with which we have performed experiments in pseudo-real scale.

“…While the field of context-aware computing is relatively young, a number of powerful context-aware systems such as Context Toolkit [9] and Hewlett Packard's Cooltown [10] have been developed, but most of them shared a weakness in supporting knowledge sharing and context reasoning because of their lack of ontology [11]. This weakness has been addressed by projects like GAIA [12], PSI [13] and VTT research [14].…”

Abstract. The availability of portable computing devices and advances in wireless networking technologies have contributed to the growing acceptance of mobile computing applications and opened the door for the possibility of seamless and pervasive services in mobile environments. However, with the dilemmas of limited device capabilities, network connectivity, transmission range and frequent changes, due to users and/or devices mobility, Internet-oriented wireless applications face challenges in terms of computation and interaction. These challenges elaborate with the inevitable demand for such applications to adapt to users' situations, their profiles, and the resources provided by the operating environment. Taking into account contextual information is an essential ingredient to cope with the frequent changes in mobile environments and hence provide adequate solutions for achieving adaptability, reliability, and seamless service provisioning. This paper introduces the use of policies over semantically modeled context as a technique for generating implicit context information and making use of context in mobile computing in general and internet-computing in specific. A context-sensitive instant messaging application demonstrates our proposed model using agent technology.
