Computing for Human Experience [v3, Aug-Oct 2010]
27Seamless integration of technology with life*“The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life ... Machines that fit the human environment instead of forcing humans to enter theirs...” Mark Weiser, The Computer for the 21st Century (Ubicomp vision)“…technology that will allow us to combine what we can do on the Internet with what we do in the physical world.” 	Ian Pearson in Big data: The next Google http://tarakash.com/guj/tool/hug2.html* From Devices to Ambient Intelligence
28But we are not just talking aboutIntelligent DesignUbicomp: Mark Wisner and othersIntelligence @ Interface: Gruber –“the system knows about us, our information, and our physical environment. With knowledge about our context, an intelligent system can make recommendations and act on our behalf.”(c) 2007 Thomas Gruber
29What is CHE? Beyond better human interactionComputing for human experience will employ a suite of technologies to nondestructively and unobtrusively complement and enrich normal human activities, with minimal explicit concern or effort on the humans’ part.FeaturesSeamless - nondestructive and unobtrusive, with minimal explicit concern or effort on part of humansanticipatory, knowledgeable, intelligent, implicit, ubiquitousEncompasses: Mobile (ubiquitous) Web, Sensor (multisensory and participatory) Web, Social Web (collective intelligence and wisdom of the crowd), multimodal

Scenario of context (Semantic Sensor Web demo)More: Semantic Sensor Web
Active Perception (Sensing – Observation – Perception) and role of ontologies and background knowledge for Situational Awareness
To enable situation awareness on the Web, we must utilize abstractions capable of representing observations and perceptions generated by either people or machines.Webobserveperceive“real-world”45
For example, both people and machines are capable of observing qualities, such as redness.observesObserverQuality* Formally described in a sensor/observation ontology46
47With the help of sophisticated inference, both people and machines are also capable of perceiving entities, such as apples.perceivesPerceiverEntity* Formally described in a perception ontology
48The ability to perceive is afforded through the use of background knowledge. For example, knowledge that apples are red helps to infer an apple from an observed quality of redness. Quality* Formally described in a domain ontologyinheres inEntity
49The ability to perceive efficiently is afforded through the cyclical exchange of information between observers and perceivers. Observer* Traditionally called the Perception Cycle (or Active Perception)sendsfocussends perceptPerceiver
50Integrated together, we have an abstract model – capable of situation awareness – relating observers, perceivers, and background knowledge.observesObserverQualitysends perceptsendsfocusinheres inperceivesPerceiverEntityWhat is new? Relevant background knowledge/ontologies are increasingly available or possible to create. Domain independent ontologies are being developed or exist… Web, scale….
Let’s review an example execution of the perception cycle, utilizing background knowledge from the weather domain.51

Trust - Background(What?) *Trust is the psychological state comprising a willingness to be vulnerable in expectation of a valued result.
(Why?) To act on a decision, it’s important to have confidence in the information from which it was derived.
(How?) Through reputation, past behavior can be used to predict future behavior.*Ontology of Trust, Huang and Fox, 2006Josang et al’s Decision Trust
Trust values converge with the increasing number of observations.What next?Trillions+ of observations (data) from human body to all devices and everything on the Globe ->  What’s meaningful to human experience?66Body Sensor NW: http://www.enterprise.mtu.edu/im/projects.htmlhttp://www.opengeospatial.org/ogc/markets-technologies/swe

Perception -> Observations -> Sense MakingSocial Components of content dictate how we perceive and process informationTextual ContentLatent crowd characteristics from contentSpatial, Temporal parametersWhen, where the message originatedPoster demographicsAge, gender, socio-economic status..
Spatio Temporal and Thematic analysisWhat else happened “near” this event location?What events occurred “before” and “after” this event?Any message about “causes” for this event?
Spatial View….Which tweets originated from an address near 18.916517°N 72.827682°E?

THEME – Understanding Casual TextGathering and processing social observationsChallenges with Casual textInformal, Domain Dependent slangs, misspellings, non-grammaticalRedundancy (everyone is tweeting the same thing)Variability (everyone is saying the same thing in many ways) off-topic noise
Context – Importance and Challenges94 Weather conditions from tweets using key   words (http://smalltalkapp.com/).Context – Importance and Challenges95 Selecting Georgia, we get the tweets    used to derive weather conditions. Primarily use Keywords without     background knowledge.
Context – Importance and Challenges96a nickname for Hip-Hop/R&B singer Chris Brown"Country Sunshine" is the name of a popular country song written by Dottie West in 1973Not snowing now!
