Abstract. The Daily Activities Diarist is an awareness system that supports social connectedness between seniors living alone and their social intimates. The Daily Activities Diarist extracts automatically an Activity-of-Daily-Life (ADL)-journal from data collected through a wireless sensor network installed at the home of the seniors. We describe the design of the system, its implementation and the lessons from two trials lasting 2 weeks each. The paper makes the case for narrative presentation of awareness information and for seamful design of awareness systems of this ilk.

Abstract. We present a formal-model of awareness-systems founded upon the focus and nimbus model of Benford et al [2] and of Rodden [19]. The model aims to provide a conceptual tool for reasoning about this class of systems. Our model introduces the notions of aspects, attributes and resources in order to expose the communicational aspects of awareness-systems. We show how the model enables reasoning about issues such as deception and plausible deniability, which arguably are crucial for enabling users to protect their privacy and to manage how they present themselves to their social network.

The realization and deployment of the Internet of Things require providing to non-programmers some level of programmatic control for tailoring system behaviour to their context and needs. We introduce a simple context-range semantics (CRS) and a context-range editor (CoRE) that support end users formulate and understand logical expressions regarding context. The editor builds on two key ideas (a) contextual information is used to evaluate and minimize logical expressions; (b) logical expressions are presented in a disjunctive normal form (DNF) thus applying a principle established in mental model theory. User tests reveal situations in which the theory regarding the intuitiveness of the DNF needs to be extended with a new element: Logical terms are easier to comprehend and formulate when grouped according to their semantic affinity. We report two experiments that demonstrate the intuitiveness of this approach and how it improves performance of non-programmers in specifying context sensitive system behaviour.

Abstract. This paper presents Amelie, a service oriented framework that supports the implementation of awareness systems. Amelie adopts the tenets of Recombinant computing to address an important non-functional requirement for Ambient Intelligence software, namely the heterogeneous combination of services and components. Amelie is founded upon FN-AAR an abstract model of Awareness Systems which enables the immediate expression and implementation of socially salient requirements, such as symmetry and social translucence. We discuss the framework and show how system behaviours can be specified using the Awareness Mark-up Language AML.
