This document provides an overview of Project Oxygen, which aims to embed computation into everyday human life through pervasive and human-centered computing technologies. It describes several key technologies being developed, including intelligent spaces (E21) that can understand speech and gestures, mobile devices (H21) that are lightweight and customizable, and networks (N21) that allow devices to automatically discover and collaborate with each other. The goal is for computation to be seamlessly integrated and accessible anywhere, through technologies like knowledge access and automation. Project Oxygen is moving closer to realizing Mark Weiser's vision of ubiquitous computing.

2. Agenda
 Pervasive, Human Centered Computing
 Overview of Project Oxygen
 Device technologies
 Network technologies
 Software technologies
 Perpetual technologies
 User technologies
 Oxygen Today
 Conclusion

3. Pervasive, Human Centered Computing
➢ Pervasive Computing
➢ Term coined by Mark Waiser
➢ Information processing is integrated into everyday objects & activities
➢ Human Centered Computing
➢ Emerging, inter disciplinary field
➢ Concerned with computing and computational artifacts
as they relate to human condition

4. Overview of Project Oxygen
 Vision
● Computation embedded into human life, like the Oxygen we breathe
 Approach
● Combination of specific user & system technologies
● User technologies address human needs
● System technologies like software, networks make devices understand
humane way of interaction
 Challenges
● Pervasive yet Embedded
● Dynamic yet Eternal
 Application

5. Device Technologies
 E21 Intelligent Spaces
● Space centered computation, embedded in ordinary environment
● Populated by cameras, microphones, displays, sound output
● Controls for physical entities like curtains, lighting, door-locks
● People interact in Intelligent Spaces naturally, using speech, gestures
 H21 Mobile Devices
● Person centered devices also the Universal Personal Appliances
● Equipped with perpetual transducers such as microphone, speakers
● Auto reconfigurable, light weight, inexpensive
● Anonymous generic devices

6. E21 Intelligent Spaces
 Space centred computation, embedded in ordinary environment
 Connected to sensors, suitably encapsulated into physical objects
 Communicate with each other and nearby handheld devices (H21)
through Dynamically Configured Networks (N21)
 E21 provide computational power throughout the system to
● Communicate with people
● Support Oxygen User Technologies
● Monitor and control their environment
 E21 software is robust, and configurable among themselves

7. Oxygen Today
 The Intelligent Room
● Capable of detecting motion
● Recognize voice patterns
● Identify a person by face
sensors

8. H21 Mobile devices
 Generic devices also called Universal Personal Appliances
 Do not carry large amount of permanent local state
 They configure themselves according to the person using them
 Being small and lightweight, they have few transducers
 They have less computational power than E21
 Can be configured to be used as radio, cellphone or even TV
 Power efficient, the software controls the power consumption

9. Oxygen Today
 The H21 Prototype

10. N21 Network Technologies
 Networks make it easy to establish ad-hoc collaborating communities of
 computer devices
 Through algorithms, protocols and middleware, they
● Configure collaborative regions automatically
● Create topologies and adapt them to change
● Provide automatic resource and location discovery
● Provide secure, authenticated and private access
 N21 networks use intentional names rather than conventional static names
 They support location discovery through proximity

11. Software Technologies
 Software systems adapt - to user, to environment, to change, to failure
 Project Oxygen's software architecture provides mechanisms for
● Building applications using distributed components
● Customizing, adapting and altering component behavior
● Person-centric rather than device-centric security
● Disconnected operation and nomadic code
 Eternal Computation: The system must never shut down or reboot
though components are upgraded, removed and reinstalled

12. Perpetual Techniques
 Two kinds of perpetual techniques
● Spoken Interaction
● Users and machine engage in interactive conversations
● Highly efficient
● Visual Interaction
● User interacts with perpetual modalities
● Use of body language and gestures

13. Spoken Interaction
 Speech recognition
 Language understanding
 Language generation
 Speech synthesis

14. Visual Interaction
 It consists of
● Visual perception subsystem, and
● It recognizes and classify objects and actions
● Complements spoken language subsystem
● Visual rendering subsystem
● Creates 3D scenes from 2D data
● Provide macroscopic view of application supplied data

15. User Technologies
 User Technologies include
● Knowledge Access
●
Access any time, anywhere, almost anything
● Automation
● Automate control of physical environment
● Collaboration
●
Connecting people

16. Knowledge Access
 Personalized repository that keeps track of what we interests us
 The search for “fat book on computers” will return person biased results
 Automated observers
● They always keep a track of the data you are looking for
● The data is modelled according to your personal profile

17. Oxygen Today
 Distribution & Mobility
 The cricket location support system
 Perceptual Interfaces
 Multimodal, multi-lingual softwares like “SpeechBuilder”
have been designed
 Security & Privacy
 Decentralised scheme of oxygen
 User never needs to revel their own location

18. Conclusion
➢ Bringing abundant computation and communication, as pervasive as
free air, naturally into people's life
➢ Mark Weiser's vision of ubiquitous, pervasive computing is gradually
becoming reality
➢ Commercial versions of H21 are ready to be launched
➢ The E21 and N21 will soon be spread everywhere, not just the labs
