Introduction What: Personalization, Ambient Awareness, Adaptation. How: Analyze used demands. Define requirements for service provisioning. Provide services that fulfill user demands. From user To Services Knowledge Movie Food People Place ?? News Money Starting point = I-centric architectural framework + Ubiquitous Attentiveness: ubiquitous computing, exchanging information between communication systems and. pro-active responsiveness of the ubiquitous environment. A (wearable) system is ubiquitous attentive when it is wakeful and alert to meaningfully interpret the possibilities of the contemporary human communication space and intentionally induces some (behavioural/system) action(s).

Definitions Ambient in I-centric computing defines the ambient or situation the actor is in given his communication space at a fixed moment in time. It includes spatial, environmental and physiological information. Ambient Awareness denotes the functionality provided by an I-centric system to sense and exchange the situation in which the individual is in at a certain moment in time

Acquiring + crunching ambient info Sensors in network, in devices or in the environment Human-machine-interfaces Actors themselves Wide area positioning technologies range from Cell-ID to enhanced GPS Short-range wireless technologies, eg IEEE or Hiperlan-II Position, inertial, motion sensors Body sensors Terminal-activity sensors Camera’s Aggregating and communicating in relation to known reference and additional situational information Different weight & ordering of the processing Multi-modality & smart I/O behaviour (later slide) Visualize a person’s location on a map or picture Name Arjan Peddemors Jaap Reitsma Maurice Markslag Room Tel Click Presence available available available Location Click

Interactions of humans and machines in processing ambient information To deduce situational state humans use: Non-verbal info (Ir-) rational decision-making Common sense reasoning Info about abstract & non-physical relationships Need to get this info transparant & made explicit H-M: sequential exchange of input & output data Res.Q: interpersonal interaction rules & strategies

Effector  a device that can modify the physical world in a way that can be detected by actors by their senses directly; convert digitial information into real world state changes; eg lights, automatic doors, loudspeakers,… Research challenges: Modeling of effectors, semantic description of effector abilities (PER Wh.Pap.), handling disconnection problems of effectors Smart I/O behaviour & modelling Intelligent I/O behaviour based on situational context eg mail message to car audio system vs textual on phone smart input - as little user interaction as possible Not only sensing information from the real world, but also modifying it Update in December

Standardisation efforts & supporting technologies ISO/TC211, ISO SQL3/MM, OGC GIS (Geographical Information Systems), Open Location Services (OpenLS), Location-interoperability Forum (LIF), Mobile Location Protocol (MLP), geography Markup Language (GML), NaVigation Markup Language (NVML), Point Of Interest exchange language (POIX), National marine Electronics Association’s (NMEA) interface and data protocol NMEA-0183, Simple text Format for the Spatial Location Protocol (SLoP), GMML: XML-based geographical information, Geospatial-eXtensible markup Language (G-XML). Magic Services API Geographic Location/Privacy (geopriv) - IETF Update due in December

Conclusions Many research questions to be solved around ambient awareness on a global scale across heterogeneous networks and technologies conforming to an appropriate open inter-working architecture Advances in sensor technology Combine and express (semantics) position information from different acquiring technologies Partial information Multiple readings from one single device Rightful evaluation of ambient indicators (aggregation in relation to a known reference, Communicating and relating to additional situational information, Proper weight and ordering of the processing of the relevant ambient indicators Sensory modelling & Requirements for cross-modality Privacy protection & policies on ambient information access and exchange Interpersonal interactions rules and strategies Standardisation specs Modeling of effectors, semantic description of effector abilities (PER Wh.Pap.), handling disconnection problems of effectors
