The idea of the project is to make computation human centered and responsive to human needs rather than having people catering to expensive machine

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.

Transcript

  • 1. Pervasive, Human Centered ComputingOverview of Project OxygenDevice technologiesNetwork technologiesSoftware technologiesPerpetual technologiesUser technologiesOxygen TodayConclusion
  • 2. What is Project Oxygen The idea of the project is to make computationhuman centered and responsive to human needsrather than having people catering to expensivemachine
  • 3. INTEGRATED TECHNOLOGY THATADDRESS HUMAN NEEDS
  • 4. Vision In the future, computation will be human-centered. It will be freely available everywhere, like batteries andpower sockets, or oxygen in the air we breathe. It will enter the human world, handling our goals andneeds and helping us to do more while doing less.
  • 5. Approach Combination of specific user & system technologies User technologies address human needs. Speech and vision technologies enable us to communicatewith Oxygen as if were interacting with another person,saving much time and effort. System technologies like software, networks make devicesunderstand humane way of interaction
  • 6. Space centered computation, embedded in ordinaryenvironment Connected to sensors, suitably encapsulated into physicalobjects Communicate with each other and nearby handhelddevices (H21)through Dynamically Configured Networks(N21) E21 provide computational power throughout the system E21 software is robust, and configurable amongthemselves
  • 7. Oxygen TodayThe Intelligent Room Capable of detectingmotion Recognize voicepatterns Identify a person by faceSensors
  • 8. Generic devices also called Universal Personal Appliances They configure themselves according to the person usingthem 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 evenTV Power efficient, the software controls the powerconsumption
  • 9.  E21(Embedded devices ) Intelligent Spaces Space centered computation, embedded in ordinaryenvironment 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
  • 10. Networks make it easy to establish ad-hoc collaboratingcommunities 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 thanconventional static namesThey support location discovery through proximity
  • 11. Software systems adapt - to user, to environment, tochange, to failure Project Oxygens software architecture providesmechanisms 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 shutdown or rebootthough components are upgraded, removed andreinstalled
  • 12. Two kinds of perpetual techniques Spoken Interaction● Users and machine engage in interactiveconversations● Highly efficient Visual Interaction● User interacts with perpetual modalities● Use of body language and gestures
  • 13. Speech recognition Language understanding Language generation Speech synthesis
  • 14.  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 supplieddata
  • 15.  User Technologies include Knowledge Access Access any time, anywhere, almost anything Automation Automate control of physical environment Collaboration Connecting people
  • 16. ADVANTAGESPervasivenessEase of usePersonalized data storage and accessSecurityElimination of need to carry around communication
  • 17. CHALLENGESTo support highly dynamic and varied human activities,the Oxygen system must master many technicalchallenges. It must be- embedded nomadic adaptable powerful, yet efficient intentional eternal
  • 18.  Bringing abundant computation and communication,as pervasive as free air, naturally into peoples life Commercial versions of H21 are ready to be launched The E21 and N21 will soon be spread everywhere, notjust the labs
