Abstract
A digital environment with a pervasive and unobtrusive intelligence able to proactively support elderly people in their daily lives, enabling them to live independently for longer, and reducing the need for long term care is the fundamental idea of the Ambient Assisted Living (AAL). After considerable research investment, there is a good understanding of the domain problem. However, the need to broaden the scope of problems being addressed is undeniable. Ecological approaches for design and development of AAL services are required in order to reinforce a strong focus on people. The chapter presents a comprehensive model based on the International Classification of Functioning Disability and Health (ICF) to characterize users, theirs contexts, activities, and participation, and to structure a semantic framework for AAL services.

Using Notification Systems to Create Social Places for Online Learning
In a general sense, it means the salience of physical, social, historical or other circumstances that may have a role in shaping activity. The term has been appropriated within a movement toward ubiquitous computing (moving computing beyond the desktop and into the world of activity) to indicate awareness within the computing system of physical conditions outside the system, such as location or user attributes.

Choosing and Adapting a Mobile Learning Model for Teacher Education
Whereas context awareness is defined as a property of mobile devices in relation to location awareness, location may determine how certain processes of learning are applied more flexibly with mobile users. The users in this case, are learners sensing their physical environment and adapting their behavior accordingly.

Putting Personal Smart Spaces into Context
Context-awareness refers to the idea that computers can both sense, and react based on their environment. Devices may have information about the circumstances under which they are able to operate and based on rules, or an intelligent stimulus, react accordingly. Context-aware devices may also try to make assumptions about the user's current situation. In addition, context-aware systems are concerned with the acquisition of context (e.g. using sensors to perceive a situation), the abstraction and understanding of context (e.g. matching a perceived sensory stimulus to a context), and application behaviour based on the recognised context (e.g. triggering actions based on context) ( Schmidt, 2002 ).

Service Discovery Techniques in Mobile E-Commerce
- information that can be used to characterize the situation of an entity where an entity is a person, place, or object that is considered relevant to interaction between a user and an application including the user and application themselves. Context-awareness is defined as: a property of a system that uses context to provide relevant information and/or service to the user, where relevancy depends on the user’s task.

An Approach to Mobile Grid Platforms for the Development and Support of Complex Ubiquitous Applications
feature of a system/application able to dynamically know the functional and non-functional characteristics of the context in which it operates. The context is defined as “any information that can be used to characterize the situation of entities (i.e. whether a person, place or an object) that are considered relevant to the interaction between a user and an application, including the user and the application themselves.” ( Dey, 2001 , p. 3).

Embedding Context-Awareness into a Daily Object for Improved Information Awareness: A Case Study Using a Mirror
A system property that defines the capability of a system to handle context information of a user, a device, and/or a surrounding environment. Examples of context are the location and current activity of a person; remaining battery time of a mobile phone; the ambient light level of a room, etc. A context-aware system should support a user’s decision making by extracting relevant and necessary information from complex and huge amount of data, should perform automated tasks on behalf of a user, and should make a user feel inconvenient and uncomfortable without it.

Programming Body Sensor Networks
The capability of computational systems of determining circumstances and scenarios in which its users may be inserted, or simply determining information that is of interest to the system. To do so, the system uses rules (intelligent algorithms) and data that can be supplied by the user itself, or obtained by sensors. These data can also lead to probabilistic information. In this case, the context awareness is not exact, but instead, a hypothesis with an associated probability value.
