• See who is going to be late or absent for a meeting

• Integrated in Outlook

• Based on GSM cell-id

Already present?

Travelling to meeting location?

Estimated time of arrival?

• Practice what you preach: live demo …

Other AWARENESS highlights

• “outstanding project” [Freeband external review June 2007]

• An integrated project !

• Two piloted integrated health demonstrators Epilepsy (including SmartSigns)

Chronic pain

• Integrated office demonstrators

• Integrated context infrastructures • Demo’s at: CeBIT 2005 and 2006, IST 2004, ICT Kenniscongres 2006,

EuroSSC 2006, CVA congress, ICMCC 2005 event, ICT Delta 2007, Freeband zorg event 2006, Sentinels event 2005, EU CREST 2004, for health insurance companies and members of parliament

• Three extensions

• Tele-treatment (2005)

• Business modeling tele-treatment (2007)

• 2008 extension

• Eight (or more?) articles in prof magazines


AWARENESS: an infrastructure based approach

• cost reduction

• handling complexity

• improved efficiency

• increased trust

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.

D0.1v4 - Lessons learned on context awareness in mobile applications

submitted to Elsevier’s Pervasive and Mobile Computing]


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.


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.

more in Erik

Meeuwissen’s talk


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.

Context-aware security

• Context is mostly seen as security threat, but:

Lesson 12: Context awareness is not only a challenge

for security, but is also useful for security to make it

more flexible, stronger and user friendly

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.

Context-aware mobile health

• 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


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
