“…It's also similar to the role-based classification approach mentioned by Beer et al [31], which classifies an unknown object by comparing its attribute sets with the known attribute templates. Approaches like these all work with uncertainty, mainly informing users of the probability of each hidden object being the target, leaving the truth to be determined by the user.…”

Abstract.A new system named Home-Explorer that searches and finds physical artifacts in a smart indoor environment is proposed. The view on which it is based is artifact-centered and uses sensors attached to the everyday artifacts (called smart objects) in the real world. This paper makes two main contributions: First, it addresses, the robustness of the embedded sensors, which is seldom discussed in previous smart artifact research. Because sensors may sometimes be broken or fail to work under certain conditions, smart objects become hidden ones. However, current systems provide no mechanism to detect and manage objects when this problem occurs. Second, there is no common context infrastructure for building smart artifact systems, which makes it difficult for separately developed applications to interact with each other and uneasy for them to share and reuse knowledge. Unlike previous systems, Home-Explorer builds on an ontology-based knowledge infrastructure named Sixth-Sense, which makes it easy for the system to interact with other applications or agents also based on this ontology. The hidden object problem is also reflected in our ontology, which enables Home-Explorer to deal with both smart objects and hidden objects. A set of rules for deducing an object's status or location information and for locating hidden objects are described and evaluated.

Abstract. Designers and developers of virtual environments have to consider that providing adaptation in virtual environments is important to comply with users' different characteristics. Due to the many possibilities of adaptation that a designer can think of, it is necessary to support the integration of adaptation in the application in a rapid and practical way. We propose to achieve this by adopting the VR-DeMo model-based user interface design (MBUID) process which supports context. In this paper, we strive to integrate adaptation in virtual environments using a context-aware design process and present a validation of this approach with two case studies, namely supporting the adaptation of switching between interaction techniques and adapting the interaction technique itself. These case studies learned us that adaptation can be easily realized using our context-aware model-based design process.

“…Therefore, in order to manage entity relationship reasoning, the authors plan to integrate the Jess library into the context framework that they have realized. In our work, we considered that the usage of an available expert system shell like Jess reduces the cost and time of development compared with writing the expert system from scratch, as it has been done in [16].…”

Abstract. Context-aware applications can sense and explore the users' context in order to provide proper and useful services to these users. These applications can react intelligently upon changes in the user's context, performing actions relevant to the user, the application itself, and the interaction between user and application. Context-aware reactive behaviors can be expressed by using rules written in a Domain-specific Language, coined ECA-DL, specially developed for context-aware applications. This paper proposes support for the development of a generic component capable of executing rules written using ECA-DL. This component executes these rules by using Jess, which is a wellknown tool for developing rule-based systems.
