Pervasive computing

  1. 1. Pervasive Computing Roy Campbell
  2. 2. Profile of one professor• Sussex University (Maths/Phys)• Burroughs City of London• University of Newcastle upon Tyne (Ph.D., M.S)• UIUC• They actually pay me to do what I like doing!
  3. 3. Advice• Things I wished I had known as an undergrad:• ml• Get Involved!• The following stories are about students who did get involved and had articles written about them.
  4. 4. III. Student News• (DCS student teams place in ACM contest)• (U of I students place 3rd in Midwest Competition)• (Two CS students win Google Anita Borg Scholarships)• (Two students, two faculty receive Data Engineering Award for 2006)• (Two CS students receive ACM awards in Student Research Competition)• (Student award winners of Second Annual Computing Habitat Competition for Siebel Center improvement)• (PhD candidate Danny Dig wins ACM competition)• (UIUC team qualifies for Japan 2007 World Finals ACM-ICPC competition)
  5. 5. 2007 News:• (Solar-decathlon news)• (I-ventures and start-ups from our undergrads)• (Computing Habitat competition winners)• (Greg Schechter wins national Yahoo! contest - beating out all our peer institution students!)
  6. 6. OUTLINE• Background• Challenges• Ideas• Publications• Solutions/Projects
  7. 7. What does this mean?• Ubiquitous• Pervasive
  8. 8. Semantics• Ubiquitous: Existing or being everywhere, or in all places, at the same time; omnipresent.• Pervasive. per- through + vadere to go Tending to pervade, or having power to spread throughout; of a pervading quality.• Pervasive is a stepping stone to ubiquity.• Does a pervasive technology become ubiquitous when its taken for granted?
  9. 9. Post Desktop
  10. 10. Active World• Spectrum of computation and communication devices.• Seamless augmentation of human thought and activity.• Enhance users behavioral context in an automated mirror, virtual or mixed world.
  11. 11. Benefits• The translation of information to/from physical properties.• The ability to transform data.• The collaborative computational environment that results from embedding devices in a network.
  12. 12. Ethics• How do we make sure only good things happen? – Surveillance – Loss of Privacy• Whether you study pervasive computing or not, this is going to be one of the problems your generation will have to solve.
  13. 13. Rapid Convergence• Distributed • Sensing• Networked • Robotics• Multimedia • Multimedia• Mobile • Wireless communications• Embedded computing • The Internet
  14. 14. Active Space: Merging the physical & computational infrastructures
  15. 15. Active Spaces organize networked computer devices into a distributed systemthat cooperates and coordinates its activities with its mobile users
  16. 16. The human endeavors of creativity and learning in areas from art, music & thehumanities to science & engineering become a crucible for new perspectives on how ubiquitous computing can impact society.
  17. 17. Our research on Active Spaces examines how ubiquitous computing can support different physical human activities, from classroom and office activities to entertainment and communication
  18. 18. Our project combines elements of HDTV, sensor networks, plasma touch panels,tracking cameras, mobile devices, speech recognition and synthesis, and location tracking into a rich tapestry.
  19. 19. To enable location aware applications we utilize various location sensing technologies includingRFID, biometrics, Bluetooth, WiFi, & Ubisense™. Ubisense represents a new class of UWB-basedsensing devices that are economic to deploy in abuilding and have an accuracy of 6 inches 95% of the time.
  20. 20. Location awareness allows ubiquitous computing environments to tailor themselves according to users’ preferences. Applications can follow usersas they move, content can be customized based onusers’ locations, and physical surroundings can be customized according to their inhabitants.
  21. 21. Gaia in the classroom empowers students andteachers with better technologies for educational interaction and facilitates communication in a seamless fashion encouraging students to participate actively even in large scale class settings.
  22. 22. We are extending the notion of Active Spaces to theSiebel Center, our new Computer Science building, & exploring the security concerns of ubiquitous computing, and new ways to harness the web, mobile devices, & location sensors into ubiquitous context-aware environments
  23. 23. Active Buildings• Applications for tours, exhibitions, seminars, lectures, meetings• Migrating, suspending, resuming sessions of interactive tasks that implement an abstract human activity• a programmable COTS infrastructure enabling context sensitive applications that allow users to interact seamlessly with a combination of physical and computer facilities.
  24. 24. Challenges for Ubiquitous Computing• How do we ensure that ubiquitous computing systems fulfill their required and intended purpose?• How do we ensure that we can trust these systems to perform as intended?• How do we produce ubiquitous computing systems efficiently and economically?
