Project oxygen

  1. 1. Submitted By:Ravi SharmaBranch-CSESemester- 6th
  2. 2. Pervasive, Human Centered ComputingOverview of Project OxygenDevice technologiesNetwork technologiesSoftware technologiesPerpetual technologiesUser technologiesOxygen TodayConclusion
  3. 3.  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. 4.  VisionFor over forty years, computation has centeredabout machines, not people. We have catered toexpensive computers, pampering them in airconditioned rooms or carrying them aroundwith us. Purporting to serve us, they have actuallyforced us to serve them. They have been difficult touse. They have required us to interact with them ontheir terms. But, In the future, computation will be human-centered. It will be freely available everywhere, like batteries and power sockets, or oxygen in the air we breathe. It will enter the human world, handling our goals and needs and helping us to do more while doing less.
  5. 5.  Challenges To support highly dynamic and varied human activities, the Oxygen system must master many technical challenges. It must be- pervasive—it must be everywhere, with every portal reaching into the same information base; embedded—it must live in our world, sensing and affecting it; nomadic—it must allow users and computations to move around freely, according to their needs; adaptable—it must provide flexibility and spontaneity, in response to changes in user requirements and operating conditions;
  6. 6.  powerful, yet efficient—it must free itself from constraints imposed by bounded hardware resources, addressing instead system constraints imposed by user demands and available power or communication bandwidth; intentional—it must enable people to name services and software objects by intent, for example, "the nearest printer," as opposed to by address; eternal—it must never shut down or reboot; components may come and go in response to demand, errors, and upgrades, but Oxygen as a whole must be available all the time.
  7. 7.  Approach Combination of specific user & system technologies User technologies address human needs. Speech and vision technologies enable us to communicate with Oxygen as if were interacting with another person, saving much time and effort. System technologies like software, networks make devices understand humane way of interaction
  8. 8.  E21(Embedded devices ) 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(Handheld devices) 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
  9. 9.  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
  10. 10. Oxygen Today The Intelligent Room Capable of detecting motion Recognize voice patterns Identify a person by face Sensors
  11. 11.  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
  12. 12. Oxygen Today The H21 Prototype
  13. 13.  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
  14. 14.  Software systems adapt - to user, to environment, to change, to failure Project Oxygens 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
  15. 15.  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
  16. 16.  Speech recognition Language understanding Language generation Speech synthesis
  17. 17.  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
  18. 18.  User Technologies include Knowledge Access Access any time, anywhere, almost anything Automation Automate control of physical environment Collaboration Connecting people
  19. 19.  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
  20. 20. 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
  21. 21.  Bringing abundant computation and communication, as pervasive as free air, naturally into peoples life Mark Weisers 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
