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

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 Just Where Are We Heading?

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? Who Am I?

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 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 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 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 Structure of this Course

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 Overview of Course Topics

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 / surfing Summary of Your Responsibilities

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 Next Class

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?

Questions so far?

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
