Context Management
• Core of the infrastructure layer, handle dynamicity
• Discovering and exchanging context information
• Request-response, publish-subscribe and event-
condition-action
Lesson 1: Context management systems are
environment-specific. Since context-aware
applications need context from different environments,
they have to interoperate with different context
management systems.

13. AWARENESS workshop - 20 March 2008 13
Context Modeling & Quality of Context
• Model raw context and high-level context
• Quality of Context describes quality attributes
• Precision, freshness, probability etc
Lesson 7: Explicitly modeling Quality of Context is
essential for application adaptation, privacy and
infrastructure efficiency.
Lesson 8: Higher Quality of Context allows more and
better application adaptivity.

14. AWARENESS workshop - 20 March 2008 14
Reasoning
• Putting intelligence in the infrastructure
• Combine context information to improve quality
• To derive ‘higher level’ context information
Lesson 6: Learning context patterns enables the
reasoning and prediction of context.
Lesson 5: Higher-level context reasoning requires,
besides statistical methods for pre-processing, fusion
and matching, rule-based methods to derive required
context.

Meeuwissen’s talk

15. AWARENESS workshop - 20 March 2008 15
Privacy
• Privacy & consent needed for user acceptance
• and legal reasons
• Context information can be anonymised or
obfuscated to reduce privacy sensitivity
Lesson 9: There is an inherent trade-off between
using context and keeping privacy, and users should
be empowered to control this trade-off themselves.
Lesson 10: The privacy preferences that control the
sharing of context information are context-aware
themselves.

AWARENESS vision on Context Awareness
• A human user is always and everywhere surrounded by a
networking environment that is able to determine automatically:
• the identity of the user, and
• the (upcoming) context information that is (or might
become) relevant to service provisioning
• so that applications adapt
themselves to the context of
the user
• and users have, anywhere,
anytime access to mobile
services
• in a secure and privacy-
sensitive manner.

• M-health = health care independent of time and place
• Using UMTS, GPRS, WLAN etc
• Conveys health signals collected by Health Body Area
Network
• Goal: improve quality of life and reducing costs
• AWARENESS adds context to m-health
• the patient – where is the patient, what is he doing etc
• the voluntary caregivers
• the professional caregivers
• Selected applications
• Tele-monitoring of epileptic seizures
• Tele-monitoring of uncontrolled movements in spasticity
• Tele-treatment of patients with chronic pain

27. AWARENESS workshop - 20 March 2008 27
A perspective on …. context
• Context is a buzz word
• Some things are not context … Context  data !!!!
• context  data
• E.g.:
• my username/password are not context
• what I type when using Powerpoint is not context
• the amount of money I transfer using my Online Banking
• What are characteristics of context then ?
• Enables user centric adaptations
• Inherently vague (due to limits in sensors)
• Often needs to be reasoned
• Extremely dynamic
• Is privacy sensitive
