1. 1 Mobile & Ubiquitous Computing Thad Starner, Jay Summet summetj@cc.gatech.edu Class I

2. 2 Introduction to the Class Introduction to Mobile & Ubiquitous Computing Class Grading, Projects, Class Participation Selection of Volunteers! Visitors who will talk about: –Past Projects –Project Ideas for this semester

3. 3 Who We Are: Your Professor: Thad Starner, Ph.D. http://www.cc.gatech.edu/~(thad|summetj) Your TA: Jay Summet

4. 4 What is Mobile Computing? Your Laptop, Cell Phone, PDA, GameBoy, etc Taking computation with you –More than just communication devices, but those (cell phones) are the “killer app”. –A subset of Mobile Computing that Thad is interested in is “Wearable Computing”

5. 5 What is Ubiquitous Computing? Making computing invisible by embedding it into the surrounding environment Integrating computation into daily life to solve human problems Before After

6. 6 (Un) Sexy Examples WiFi Supermarket self checkout kiosk Signs in the MARTA station telling you how long until the next train arrives Motion Sensing Lights All the sexy examples are still in science- fiction movies or research labs.

7. 7 Major Themes Interface (Human Computer Interaction) – How do you tell the computer what you want? How does it tell you what it knows? Power – How long can it go, and what can it do? Privacy – Who can see your secrets? Networking – Who (what) else can you communicate with, and how fast?

8. 8 Grading: Projects & Class Participation 80% of your grade will be 2 class projects –2 person teams (can change between projects) –2 nd ' project will result in a publication quality paper –2 nd project can be a continuation of the 1 st 20% of your grade will be class participation –Attendance: Mandatory –Effectiveness as Discussion Leaders & Participants –Teammate's evaluation(s)

9. 9 Class time will be used for: Discussion (of the readings on) the history & current research Lecture & Tutorials (how to build stuff, and how to evaluate it once you have) Presentations by visiting researchers Group work times (rarely, set up a meeting time outside of class)

10. 10 Who will be our first Discussion Leaders? Read: –The invention of the first wearable computer. E.O. Thorp. –Augmenting Human Intellect: A Conceptual Framework.-Douglas Engelbart –Sketchpad & Virtual Reality portions of Ivan Sutherland's profile. Lead Discussion (Next Tuesday)

11. 11 Everybody Else (& Discussion Leaders) For next Tuesday, read: –Vannevar Bush – As We May Think. –Vernor Vinge – Synthetic Serendipity –Mark Weiser – The Computer for the 21 st Century

12. 12 Visitors bearing Project Ideas Kent Lyons - Wearable Computers Matt Sanders – IMS (Ip Multimedia Subsystem) Dan Ashbrook – Many Projects Tracy Westeyn – Many Projects kent@cc, msanders@cc, anjiro@cc, turtle@cc

13. 13 Todo: Go to the class Bliki, add a paragraph and optional picture about yourself Complete on-line IRB Certification training Start reading for next Tuesday Think of Project Ideas Look for Project Partners

14. 14 Backup Slides...

15. 15 Front Projection Inexpensive: –Display Screen –Installation –Reconfigurable Effective use of space But shadows & blinding light are problematic

16. 16 Shadows

17. 17 Blinding Light

18. 18 Rear Projection No shadows! But extra costs... –Display Material –Installation –Space cost ($77 sq. ft.) –Immobile Physical space constraints

19. 19 Projected light is a larger problem as you add more projectors.

20. 20 Active Virtual Rear Projection Detects occluders, turns off pixels they are occluding, and fills in those pixels with alternate projectors.
