_{Research Project „Platform for the support of social and health aspects}

in an age appropriate autonomous life“



_Goal

 Let older people stay longer in their homes 

_Concepts

 Development and operation of an intelligent service platform with open interfaces for third-party service provider („market place“)

 Technology easy to install, no maintenance necessary, easy interfaces

 Detection of (slow) changing health states (accompanying medical study)

 Context-dependent support by private members of social network and healthcare support by professional service providers

_Aladdin

_{: software infrastructure for mobile context-sensitive}

applications

 Abstraction of context acquisition and modelling

 Device (sensor) capability detection features

 Scalable concept with extensibility “on-the-fly”

 Dynamic downloads of components (plug-ins) during runtime

 Outsourcing of plug-in development to domain experts

 Distributed open plug-in repository

 Central access right management (local context firewall)

 Support for registered, checked apps and plug-ins

 Allows for domain-neutral development of context-based applications

(13)



_{Current Implementation}

 Google Android / Java

 OpenSource / Multithreading / Multitouch

 Aladin Framework as Android Background Service  “Context-Firewall” for registered Apps

 Communication via IPC

 Capability Manager:

 Detects Device Functions

 Context Manager:

 Management of Context Acquisition Plug-Ins

 Plug-In Repository

 Embedded Apache Felix OSGi Container for Plug-In Bundle Management

 First successful tests on Motorola Milestone
