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

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

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.

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

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

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

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!!!
