2. INTRODUCTION Machine centred. We are serving them. Difficult to use.
Right now, Computers have required us to interact with them on their own terms and speak their language
Solution is OXYGEN.

3. WHAT IS OXYGEN ??
Bringing abundant computation and communication, as pervasive and free as air, naturally into people's lives.
Computation will be
human-centered.
freely available everywhere, like batteries and power sockets, or oxygen in the air we breathe.
configurable generic devices, either handheld or embedded, will bring computation to us, irrespective of our location.
We won't have to type, click, or learn new computer jargon.
Instead, we'll communicate naturally, using speech and gestures that describe our intent

6. DEVICE TECHNOLOGIES... H21 Or HANDY 21
anonymous devices that do not carry a large amount of permanent local state
they configure themselves through software to be used in a wide range of environments for a wide variety of purposes.
customize itself to the user's preferred configuration
contain board-level antennas that enable them to couple with a wireless N21 network, embedded E21, or nearby H21s to form collaborative regions
H21s can serve as cellular phones, beepers, radios, televisions, geographical positioning systems, cameras, or PDAs

8. DEVICE TECHNOLOGIES...
E21
Environmental devices, together called an E21, provide a local-area computational and communication back-plane for an intelligent space.
E21s are connected to nearby sensors, actuators, and appliances, suitably encapsulated in physical objects.
communicate with each other and with nearby H21s through dynamically configured networks N21s.
provide sufficient computational power throughout the environment
to communicate with people using natural perceptual resources, such as speech and vision,
to support Oxygen's user technologies wherever people may be, and
to monitor and control their environment.

10. NETWORK TECHNOLOGIES... N21
They configure and reconfigure themselves automatically
Networks route heterogeneous traffic efficiently,
N21s, connect dynamically changing configurations of self-identifying mobile and stationary devices.
integrate different wireless, terrestrial, and satellite networks into one seamless internet
Through algorithms, protocols, and middleware, they deal with
Configuration of Collaborative regions
Resource and location discovery
Security
Adaptation

14. PERVASIVE TECHNOLOGIES...
SPEECH
Humans communicate with computers, in much the same way they communicate with one another, using speech.
without having to remember a URL, search through the Web for a pointer to a document, or use keyword search engines.
provides a number of limited-domain interfaces, as well as mechanisms for users to navigate effortlessly from one domain to another
The spoken language subsystem is an integral part of Oxygen's infrastructure, not just a set of applications or external interfaces
Four components
Speech recognition
Language understanding
Language generation
Speech synthesis

16. PERVASIVE TECHNOLOGIES...
VISION
say "show it to me there," turning their heads or pointing with their arms to indicate where.
using facial expressions and gestures, without having to express everything in words.
Computers recognize and classify features and actions
They detect patterns and object interactions
The visual processing system contains
visual perception
visual rendering
Components
Object recognition
Activity monitoring and classification

17. USER TECHNOLOGIES... Oxygen user technologies include:
Automation technologies:
which offer natural, easy-to-use, and adaptive mechanisms for automating and tuning repetitive information and control tasks.
Collaboration technologies
which enable the formation of spontaneous collaborative regions that accommodate the needs of highly mobile people and computations.
They also provide support for recording and archiving speech and video fragments from meetings.
Knowledge access technologies
which offer greatly improved access to information, according to the needs of people, applications, and software systems.
They allow users to access their own knowledge bases

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