  6. Ubiquitous Computing is ComingSensors Everywhere • RFIDs already in greater use than you may realize • Wal-Mart mandate of Jan 2005

  7. Read my important email Ubiquitous Computing is Coming Rich Variety of Inputs and Outputs

  8. Ubiquitous Computing is Coming All Wirelessly Connected • Short-range wireless for consumers • Bluetooth, HomeRF, 802.11 • Near Field Networks • Personal Area Networks • Transmit data thru the body

  9. Just Where Are We Heading? • These are the tech trends, but quo vadis? • What do we really want ubicomp to be? • What’s the “right” way to do it? • Many different issues • Interaction Design, Systems, HCI, Public policy, … • Different communities, different vocabulary, different papers • Goals of this course • Discuss and understand these issues • Help advance state of the art

  10. Who Am I? • Assistant professor in Human Computer Interaction • Undergrad at Georgia Tech, CS and Math • PhD in Computer Science from Berkeley • Dissertation work on privacy and ubicomp systems • Location based services • How to make them easier to build? • Compelling applications? • Usable privacy and security • How to manage in ubicomp environment?

  11. Structure of this Course • Readings • Every class will be several readings • At beginning of class, turn in summary of each paper • 3-8 sentences plus a highlight • Something interesting or noteworthy • A question to discuss in class • A point you disagree with

  12. Structure of this Course • Lecture and class notes • Each student needs to do at least one lecture • Each student needs to take class notes at least once (summary of class discussion) • Will be used for an instructor’s guide

  13. Structure of this Course • Lecture • Present overview of readings • Highlight what you think are interesting points • Outline some questions for discussion • Feel free to be creative here • read and present related work • present some of the optional reading materials • demonstrate software mentioned in the reading • critique a design discussed in the reading • split class into separate groups, each discussing a question • set up class to debate for or against a position • design a class exercise for your classmates

  14. Structure of this Course • Course project • Do a piece of substantial research • Teams of 2-3 • “Conference paper” as deliverable • Kinds of projects • Design-oriented • Implementation-oriented • Evaluation-oriented • Mixture of above • We’ll form teams Feb 22

  15. Overview of Course Topics • Visions and Challenges of Ubiquitous Computing • Privacy and Security • Context-Awareness • Location sensing, communication, evaluation • Applications • Smart homes, Capture and Access, Mobile groups • Systems • Sensor networks, RFIDs

  16. Summary of Your Responsibilities • Read papers before class • Bring printout of summary + highlight for each paper • Signup to do a presentation • Signup for lecture notes • Will bring in signup sheet Thursday • Need volunteer for this Thursday for lecture notes • Course project • Please minimize use of laptops for email / surfing

  17. Next Class • Readings for next class • The Computer for the Twenty-First Century, by Mark Weiser • Synthetic Serendipity, by Vernor Vinge • Mike Villa's World, by Harry Goldstein • Only two summaries for next time • One for Weiser’s paper • One for the scifi story

  18. Important Questions to Think About • Original vision of ubicomp written in 1991! • Why haven’t we achieved it yet? • How to manage this complexity? • Things barely work together today • Overload of information • What are the core devices? • Buy it at Home Depot, plug it in, and you’re good to go! • What are the core services of this world? • Equivalent of Google, Yahoo, and Ebay? • Is this really a world we want to live in?

  19. Questions so far?

  20. Class Exercise • Break up into pairs • Introduce self to neighbor • Background, why you are taking course, what you hope to get out of the course • Merge into groups of four • Repeat intros • Merge into groups of eight • Elect a leader (tallest, oldest, closest to door, coolest phone) • Summarize reasons why people taking course and what they hope to get out of it • Can stop at groups of eight
