SEMINAR ON
INTRODUCTION
o Machine centred.
o We are serving them.
o Difficult to use.
o Right now, Computers have required us to interact with them on their own terms and speak their language
o Solution is OXYGEN.
WHAT IS OXYGEN ??o Bringing abundant computation and communication, as
pervasive and free as air, naturally into people's lives.
o Computation will beo human-centered.o freely available everywhere, like batteries and power sockets,
or oxygen in the air we breathe.
o configurable generic devices, either handheld or embedded, will bring computation to us, irrespective of our location.
o We won't have to type, click, or learn new computer jargon.
o Instead, we'll communicate naturally, using speech and gestures that describe our intent

TECHNOLOGIES...o Oxygen device technologies
o H21- Hand heldo E21- Embedded
o Oxygen network technologieso N21- Network
o Oxygen software technologies
o Oxygen perceptual technologieso Visiono Speech
o Oxygen user technologieso Knowledge Accesso Automation o Collaboration
DEVICE TECHNOLOGIES...o H21 Or HANDY 21
o anonymous devices that do not carry a large amount of permanent local state
o they configure themselves through software to be used in a wide range of environments for a wide variety of purposes.
o customize itself to the user's preferred configuration
o contain board-level antennas that enable them to couple with a wireless N21 network, embedded E21, or nearby H21s to form collaborative regions
o H21s can serve as cellular phones, beepers, radios, televisions, geographical positioning systems, cameras, or PDAs
H21
DEVICE TECHNOLOGIES...o E21
o Environmental devices, together called an E21, provide a local-area computational and communication back-plane for an intelligent space.
o E21s are connected to nearby sensors, actuators, and appliances, suitably encapsulated in physical objects.
o communicate with each other and with nearby H21s through dynamically configured networks N21s.
o provide sufficient computational power throughout the environment o to communicate with people using natural perceptual resources,
such as speech and vision, o to support Oxygen's user technologies wherever people may be, and o to monitor and control their environment.
Devices used in E21

NETWORK TECHNOLOGIES...oN21
o They configure and reconfigure themselves automatically
o Networks route heterogeneous traffic efficiently,
o N21s, connect dynamically changing configurations of self-identifying mobile and stationary devices.
o integrate different wireless, terrestrial, and satellite networks into one seamless internet
o Through algorithms, protocols, and middleware, they deal with
o Configuration of Collaborative regionso Resource and location discoveryo Securityo Adaptation
NETWORK TECHNOGIES...o Network Today
o Grid o Spano Chord o Intentional Naming System (INS)

SOFTWARE TECHNOLOGIES...
o Software infrastructureso MetaGlueo COREo Clicko SUDS
PERVASIVE TECHNOLOGIES...oSPEECHo Humans communicate with computers, in much the same way they
communicate with one another, using speech.
o without having to remember a URL, search through the Web for a pointer to a document, or use keyword search engines.
o provides a number of limited-domain interfaces, as well as mechanisms for users to navigate effortlessly from one domain to another
o The spoken language subsystem is an integral part of Oxygen's infrastructure, not just a set of applications or external interfaces
o Four componentso Speech recognitiono Language understandingo Language generationo Speech synthesis
Conversational system architecture

PERVASIVE TECHNOLOGIES...o VISION
o say "show it to me there," turning their heads or pointing with their arms to indicate where.
o using facial expressions and gestures, without having to express everything in words.
o Computers recognize and classify features and actions
o They detect patterns and object interactions o The visual processing system contains
o visual perception o visual rendering
o Componentso Object recognitiono Activity monitoring and classification
USER TECHNOLOGIES...o Oxygen user technologies include:o Automation technologies:
o which offer natural, easy-to-use, and adaptive mechanisms for automating and tuning repetitive information and control tasks.
o Collaboration technologieso which enable the formation of spontaneous collaborative
regions that accommodate the needs of highly mobile people and computations.
o They also provide support for recording and archiving speech and video fragments from meetings.
o Knowledge access technologieso which offer greatly improved access to information, according
to the needs of people, applications, and software systems.o They allow users to access their own knowledge bases

oEducation
CONCLUSIONS...o Project Oxygen is a project to build a human centered, pervasive
computer.
o It is a $50 mn project sponsored by “oxygen alliance” which includes o Acer Inc., o Delta Electronics Inc., o Hewlett-Packard Co., o Nippon Telegraph and Telephone Corp., o Nokia Corp. and o Philips Research, a unit of Koninklijke Philips Electronics N.V.
o Started in 1999, but not yet completed.
o Concept of N21 and INS are very difficult to be practical.
o Answers to many questions yet to be revealed!!!
