What’s Ubiquitous Computing?

“The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it”

- by Mark Weiser “The Computer for the 21st Century,” Scientific American, vol.253, no.3, pp.94-104, Sep. 1991

“The whole purpose for Ubicomp is, of course” the applications”

Dr. Mark Weiser (52-99) 76-79: Ph.D., in CS, U. of Michigan 70-87: Prof., in CS, U. of Maryland 87-99: Xerox PARC (CTO): 99.4.27: Gastric cancer at 46

Context-aware Interaction• Context refers to the physical and social situation

in which computational devices are embedded. • One goal of context-aware computing is to

acquire and utilize information about the context of a device to provide services that are appropriate to the particular people, place, time, events, etc.

• Context can be used to interpret explicit acts, making communication more efficient.

• The design of computing artifacts must take into account how people draw on and evolve social contexts to make the artifacts understandable, useful, and meaningful.

• How to be aware of the context– Pervasive sensing: instrument a space with sensors– Info fusion & context analysis


What is Context-aware App Reqmts?• Context specification – support specifying

needed context• Discovery – locating components that can

acquire and act on context• Separation of concerns – separate the

acquisition of context from the use of context• Storage - context history important• Interpretation – abstract to higher level• Transparent communications – simplify

application development• Constant availability – context needs to be

acquired 24 hours a day and 7 days a week

The three waves of Internet• The first wave of the Internet consisted prima

rily of text and data services such as e-mail and FTP.

• The second wave was the web which improved ease of use and facilitated the transfer of images, sound and video.

• The third wave is the integration of applications, p2p networking, open source, distributed computing enabled by next generation web services, semantic web and high speed networks

What are web services?• Allows definition of services as well pictures images and

text within the web– WSDL uses XML to describe port bindings between services

• An application invokes a web “service” across rather than a software subroutine within a large monolithic program

• Similar in concept to CORBA but not language or platform dependent

• Foundation of IBM Websphere, Microsoft .NET, Sun’s ONE architecture

• Initially started as solution for eBusiness portals and ASPs

• With Third Wave using P2P, semantic web, etc has much greater applicability and universality to distance education, eHealth, eScience, etc


Why Semantic Web?Problem: today’s Web is designed primarily for human use.

1) Researchers are developing semantic markup of • Web service properties and capabilities,• users’ preferences and constraints,• reusable Web agent procedures

to make services computer-interpretable, use-apparent,

and agent-enabled.

2) Researchers are developing agent technology that exploits

semantic markup to support automated Web service

discovery, execution, composition and interoperation.


Tim Berners-Lee’s Semantic Web


Why Ontology?

• To share common understanding of the structure of information among people or software agents

• Semantic web aims at machine understandability– Semantic markup will be added to web resources– Markup will use ontologies for shared understandin

g


Ontology

• An explicit specification of a conceptualization

• A shared understanding of some domain of interest

• Provides– A common vocabulary of term– Some specification of the meaning of the

terms– A shared understanding for people and

machines
