    • 2de IBBT Brokerage Event Break-out Sessie Context Aware Services Sessieleider: Piet Demeester IBBT Program Manager: Nico Verplancke
    • 2de IBBT Brokerage Event – Context Aware Services Session chair & objectives Session chair: Piet Demeester IBCN-INTEC / UGent Objectives: IBBT = demand driven research Interaction with industry and other organisations Identification of research topics Identification of interested parties 2
    • 2de IBBT Brokerage Event – Context Aware Services Topics Concept of context aware services Market Potential Challenges and requirements Discussion 3
    • 2de IBBT Brokerage Event – Context Aware Services 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. 4
    • 2de IBBT Brokerage Event – Context Aware Services Concept Context information encompasses: Location information Proximity to devices, places and persons Environment factors as weather, temperature, time, traffic Status information of devices Behavior of the user (e.g. talking, sleeping, walking, …) Personal fitness / health / … … 5
    • 2de IBBT Brokerage Event – Context Aware Services Market Potential - 3 days business trip to Vienna - needs regular medication Gent 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 / hospital 6 loaded in GPS

    • 2de IBBT Brokerage Event – Context Aware Services Market Potential Location/context technology vendors Equipment vendors, Terminal manufacturers Mobile network operators LBS/context middleware providers Content providers Application developers Portals and location/context data brokers … 8
    • 2de IBBT Brokerage Event – Context Aware Services Market Potential Services GPS navigation systems Proximus GeoServices Map me: Where am I? Nearby: What’s around me? Itinary: How do I get there? Friend-finder applications Localisation of (the mobile phones) of friends or family Monitoring traffic streams 9
    • 2de IBBT Brokerage Event – Context Aware Services Market Potential Location Determination GPS GSM WiFi RFID Bluetooth ZigBee … Commercial platforms Location servers (Alcatel/Siemens/etc.) intended for GSM networks Software platforms for deploying location-based services (e.g. Milestone) 10
    • 2de IBBT Brokerage Event – Context Aware Services Market Potential Context Toolkit Software toolkit for rapid prototyping of context- aware applications Features: Separation of context sensing/acquisition from context use, context aggregation and context interpretation. SOCAM (Service-Oriented Context-Aware Middleware) Context model based on ontologies Different components implemented as separate services in OSGi … 11
    • 2de IBBT Brokerage Event – Context Aware Services 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. 12
    • 2de IBBT Brokerage Event – Context Aware Services 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 power Wired 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. 13

    • 2de IBBT Brokerage Event – Context Aware Services Challenges & Requirements 15
    • 2de IBBT Brokerage Event – Context Aware Services Challenges & Requirements Several 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 aggregation Allowing rapid development of context-aware services by 3rd party developers Easy deployment of new services (e.g. by using OSGi for the home gateway). Centralized or distributed 16

    • 2de IBBT Brokerage Event – Context Aware Services Challenges & Requirements Security en privacy Location 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. Usability Services should be invisible to the user Adoption What do users expect from context aware services and what is acceptable ? What context does the user want How does the user impact on its context Legal issues 18
    • 2de IBBT Brokerage Event – Context Aware Services Conclusions Context detection infrastructure (sensors, …, discovery, …, identification, …) Context aware terminals and actuators Interconnection networks Service architectures Service creation platforms Context representation and handling Security architectures User requirements Legal constraints Business models >8 interested parties 19
    • 2de IBBT Brokerage Event – Context Aware Services Conclusions Input from attendees during session (1): Existing technologies can indeed be used to process ontologies and implement context reasoners. Context creation and aggregation of information from heterogeneous sources is important Standards 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 configuration interfaces are necessary. 20
    • 2de IBBT Brokerage Event – Context Aware Services 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! 21
    • 2de IBBT Brokerage Event – Context Aware Services 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. 22
    • 2de IBBT Brokerage Event – Context Aware Services Background Break-out reeks 2 (16u00-16u45) Context Aware Services Mobiele, geconnecteerde toestellen en gebruiker bieden mogelijkheden voor nieuwe diensten die context-gebaseerd zijn. Locatie in het algemeen, proximity tot andere toestellen, omgevingsfactoren, ... kunnen triggers of enablers zijn van specifieke diensten. Mogelijk onderzoek binnen dit thema: nieuwe diensten, enabling technologie (software/devices/netwerk), adoptie, usability, likability, business modellen. Interessant aan dit thema is ook dat hier de volledige waardeketen van dienstenleverancier, tot telecom-operator en software/hardware vendor een bijdrage in kan leveren. 23
