Concept
Context is any information that can be used to characterize the situation of an entity. An entity is a person, place, or object that is considered relevant to the interaction between a user and an application, including the user and application themselves. [A. Day and G. Abowd, 1999]Context aware services automatically adapt to the environment of a user, for instance to the location, time, or physical condition (e.g. hart rhythm and blood pressure) of a person. The social context of users is an important determinant for the information needs and well being of people. People are truly social beings.

Market Potential
- 3 days business trip to Vienna- needs regular medication
Vienna
- From agenda it is detected that Bob is leaving for 3 days- It is checked that he didn’t take his (RFID tagged) medication with him warning on his cell phone- It is raining in Vienna also warning to take umbrella
- Bob gets ill in Vienna (detected by sensor)- Doctor at home is automatically consulted- Bob should go to a specialized hospital in Vienna- Taxi is automatically ordered and location of Bob / hospitalloaded in GPS

Major Challenge
Now:Existing solutions are mainly outdoor applications based on location information provided by GPS or GSM networks.
Future: Also indoor applications (home/office) where location information is provided by WiFi, RFID, …Also services where device, user and environment information is taken into account using advanced sensors and sensor networks.

Challenges & Requirements
Accurate position determination in buildings Difficult due to reflections, absorptions, movement, …
Different types of sensors (health monitoring, weather conditions, …)Terminals : context aware, (ultra) low powerWired and wireless communication between all kinds of devices in different environments (home, office, vehicle, public place, outdoor,…)It should be possible to automatically discover devices. As there exist several protocols (UPnP, Jini, etc.) bridging is needed.

Challenges & Requirements
16
2de IBBT Brokerage Event – Context Aware Services
Challenges & RequirementsSeveral kinds of context information have to be aggregated and represented in a standardized way
This representation should be formal so that extra information can be added by reasoning.Standard representations of e.g. a house topology allow easy development of new context-aware services.
Software platforms needed for the servers and access gateways.
Data aggregationAllowing rapid development of context-aware services by 3rd
party developersEasy deployment of new services (e.g. by using OSGi for the home gateway). Centralized or distributed

Challenges & Requirements
Security en privacyLocation information is interesting for marketing purposes or insurance companies. It can also lead to embarrassing situations or even harassment.This information should be protected and users should be able to choose which information can be disclosed and which information is private.
UsabilityServices should be invisible to the user
AdoptionWhat do users expect from context aware services and what is acceptable ? What context does the user wantHow does the user impact on its context
Legal issues

Conclusions
Input from attendees during session (1):Existing technologies can indeed be used to processontologies and implement context reasoners.Context creation and aggregation of information fromheterogeneous sources is importantStandards are needed for representing context information.Interesting application: addition of context data in content (e.g. videos) through meta-data level data.Identification of persons is required for correct and secure service execution.Usability aspect is important: easy user and configurationinterfaces are necessary.

Conclusions
Input from attendees during session (2):Discovery of devices is required.Remote installation of new services on terminals is required as well.User requirements:
Adjustable profile (presence status).Personal configuration.
Which new services and features are possible? New business models? Sensors to detect the intention of a user (e.g. telephone call with a friend vs. call with boss)Use past context information to automatically learn habits, intentions, …Using context information for billing!Context aware advertisements!

Goal of Break-Out session
De doelstelling van de break-out sessies is de thema’s die zouden kunnen leiden tot projectvoorstellen verder uit te diepen, en potentiële trekkers voor een mogelijke indiening te detecteren. Idealiter zal de break-out leiden tot een potentiële cluster van partners en uitwisseling van contactgegevens. Op basis hiervan zal de coördinator denodige initiatieven nemen om de partners samen te brengen en de proposal verder uit te werken rond een gezamenlijk interessedomein.

Background
Break-out reeks 2 (16u00-16u45)Context Aware ServicesMobiele, geconnecteerde toestellen en gebruiker biedenmogelijkheden voor nieuwe diensten die context-gebaseerdzijn. Locatie in het algemeen, proximity tot anderetoestellen, omgevingsfactoren, ... kunnen triggers of enablers zijn van specifieke diensten. Mogelijk onderzoekbinnen dit thema: nieuwe diensten, enabling technologie(software/devices/netwerk), adoptie, usability, likability, business modellen. Interessant aan dit thema is ook dat hierde volledige waardeketen van dienstenleverancier, tot telecom-operator en software/hardware vendor een bijdragein kan leveren.
