Design of Context-Aware Applications Based on Web Services [Cha04]

• Development of context-aware apps.

• Architecture supporting context-awareness at run-time.
• design the application to be context-aware.

• Web services is widespread and “loosely coupling” approach to integration of application

Design of Context-Aware Applications Based on Web Services

• Service Oriented Architecture (SOA) [Cha04]

• Context Capturing
• Context Interpreting
• Context Modeling
• Context Dissemination
• Context Adaptation
• Data flow (content)
• Visualization (UI)
• Application behavior (service)

ContextPhone: A Prototyping Platform for Context-Aware Mobile Applications [Rae05]

• Software platform running on Symbian OS (Nokia Series 60 Smartphone).

• Design goals:

• visualizes Context as a resource.
• incorporate existing applications.
• fast interaction and unobtrusiveness.
• ensure robustness.
• enable rapid development

ContextPhone: A Prototyping Platform for Context-Aware Mobile Applications [Rae05]

• Modules [Rae05]

Context Modelling and Management in Ambient-Aware Pervasive Environments[Str05]

• DAIDALOS University Scenario:

• Organization of daily life at university (friends, appointments and reservations, classes, projects, exams, entertainment)
• Locating people and devices on campus, checking availability, discovering local services.
• Personal broadcasting (of classes and speeches)
