  1. Pervasive ComputingUbiquitous computing resources Agenda • Area overview • Four themes • Challenges/issues Pervasive/Ubiquitous Computing • Move beyond desktop machine • Computing is embedded everywhere in the environment CS/PSY 6750

  2. Ubicomp Notions • Computing capabilities, any time, any place • “Invisible” resources • Machines sense users’ presence and act accordingly Video Examples • Ambient Room - H. Ishii, CHI ‘98 • Beyond the Desktop - J. Rekimoto, CHI ‘00 CS/PSY 6750

  3. Four Themes • Automated capture of experiences with easy access • Context-aware/sensitive interactions and applications • Ubiquitous services independent of devices/platforms • Natural/Implicit interfaces CS/PSY 6750

  4. 1. Automated Capture • Motivation • Record-taking is hard • Multiple streams of information need to be captured • Machines are better at some of these things than we are Examples • Meeting capture (scribe at Xerox PARC), Mark Weiser • Classroom 2000 CS/PSY 6750

  5. LiveBoard CS/PSY 6750

  6. Classroom 2000 CS/PSY 6750

  7. Issues • Stream integration -- At what level? • Very finest level of actions or more coarse? • Modifying a record after the fact • Can student notes be added later? • Networked interaction • Why can’t your notes be put up on the Liveboard? CS/PSY 6750

  8. 2. Context-Aware Computing • Computing services sense aspects of environment (location, user emotion,…) and tailor provided services • Walk into conference room, my email is projected on a big screen there Issues • How to integrate all the different aspects of context? • What about the loss of privacy? CS/PSY 6750

  9. Examples • Active Badge & PARCTab • Shopping assistant • Cyberguide • Perception system for recognizing user moods from their facial expressions • House where position is sensed and temperature adjusted automatically CS/PSY 6750

  10. Augmented Reality CS/PSY 6750

  11. 3. Ubiquitous Services • Care about service, not application • Want to receive a message using whatever device is handy nearby • Message is tailored to work according to device Issues • What is software infrastructure for integration? • Do we get it by just adopting some standard? CS/PSY 6750

  12. 4. Natural/Implicit Interfaces • Computer interfaces and devices are more natural interaction tools • Pen input • Speech • Gesture • Tangible interfaces Example • Pen applications • Speech applications • H. Ishii’s tangible UI work CS/PSY 6750

  13. Issues • Errors are more likely (handwriting recognition, speech, …) How to discover and correct them? • Is there truly value added? CS/PSY 6750

  14. Wearable Computing • Computation devices accompany you, rather than you seeking them out • T. Starner CS/PSY 6750
