PROJECT OXYGEN

1. SEMINAR ON PROJECT OXYGEN Presented By: VIJET R HEGDE 3VC05IS056

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

4. CHALLENGES... • Pervasive— • embedded— • nomadic— • adaptable— • powerful, yet efficient— • intentional— • Eternal—

5. TECHNOLOGIES... • Oxygen device technologies • H21- Hand held • E21- Embedded • Oxygen network technologies • N21- Network • Oxygen software technologies • Oxygen perceptual technologies • Vision • Speech • Oxygen user technologies • Knowledge Access •  Automation  • Collaboration

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

11. NETWORK TECHNOGIES... • Network Today • Grid • Span • Chord • Intentional Naming System (INS)

12. Intentional name • [service = camera] • [building = NE43 • [room = 510]] camera510.lcs.mit.edu INS WORKING Lookup image Resolver self-configuration Intentional name resolvers form an overlay network Late binding: integrate resolution and message routing

13. SOFTWARE TECHNOLOGIES... • Software infrastructures • MetaGlue • CORE • Click • SUDS

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

18. SCENARIOS...

19. Other Applications • Business applications • Medical field • Education

20. CONCLUSIONS... • Project Oxygen is a project to build a human centered, pervasive computer. • It is a $50 mnproject 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!!!
