1 Pervasive & Ubiquitous Computing (UbiComp) Lecture #1: Introduction Hao-hua Chu ( 朱浩華 )

2 What is UbiComp? 30-minute Introduction

3 Course Topics Be different (better) from last year –Still formulate the topics –Reading reference list will be finalized next week. UbiComp vision Context-aware, smart object Tangible interaction Ambient display Persuasive computing Cyber-physical systems

4 Course Objectives To prepare us (students and faculty) for research in UbiComp research. Learning by in-class discussion Learning by projects Learning by reading & listening papers

5 What more can you get out of this course? Develop your own belief where digital technology is going Learn research experiences –Scenario, problem definition, related work survey, design & implementation, evaluation, etc. –Reading, writing, and presentation skills

6 Collaborative Learning This is a research seminar course, so everyone (faculty and students) will contribute to the learning process. –Idea generation & discussion –Project presentation –Paper presentation UbiComp is a new, fast changing field, so faculty may not know all materials.

7 Course Format Precise details are yet to be determined. Take-home (individual) & in-class (group) exercises –Add an ambient display to your most favorite everyday object to enhance that most “favorite” aspect. –Think about one of your bad habits – come up with persuasive technology to correct your bad habit. –Upload & share exercise answers on course WiKi In class [may or may not] discuss 3+ papers on a specific topic. –Papers are used as reference for exercises

8 Project Component Rapid research prototype of an UBICOMP application in one semester. –The project ideas come from take-home or in-class exercises. –Push you to do some research –Find a fit with your current research –Learn some team work

9 Lifecycle of a Research Project Define motivation scenario (an interesting story) –Emphasize the parts of scenario where it is currently not possible, but with your idea, it will become possible. –Show me a proof-of-concept demo prototype Survey related work Design –Differentiate your work from related work –What’s new? Why is it significant? Rapid prototype implementation Evaluation of prototype implementation –Define evaluation metrics –Experiments & user studies Shoot a video & write a report

10 Project Phases Phase 1: project idea presentation (4 weeks) –Fun, realizable within one semester time framework and computing equipments, has a research component. –[Scenario] Phase 2: project proposal document (4 weeks) –Form teams, define goals, plan, and needed equipments. –[Problems, related work, and design] Phase 3: progress checkpoint (4 weeks) –[Preliminary prototype, evaluation metrics] Phase 4: project working prototype and final report (4 weeks) –Working prototype demonstration

11 Samples of previous year projects? You may have already seen some of them …

12 Toys for your projects NTU Zigbee Taroko nodes Crossbow motes Nokia and Windows CE Smart phones Smart phones (iPhone & HTC Diamond) Sparkfun Sensors: light, tilt, temperature, accelerometer, pressure, weight, orientation, ultrasound, etc. Philgets RFID kits

13 More Toys for your projects Passive RFID tags & readers (Skyetek and Alien) Biometric sensors (heart rate, BVP, GSR, etc.) Projectors WiFi based location systems (ekahau.com) Ultrasound-based positioning systems (Navinote or Cricket motes) LCD TV Use your imagination –Anything you can find on the Internet or from your own lab … –However, budget may be limited 

14 Grading Class Participation (? %) Project (? %)

15 Course Requirements Class attendance (MUST!) –Please don’t register if you are going to miss many classes. Must be able to talk & exchange ideas with others Creativity Good programming skill Willing to learn hardware/software skills (by yourself) Willing to spend extra time & efforts than what a regular course would need

16 TA & Students Intro TA: Ted Please tell us about: –Current (future) research area, interests, & faculty advisor –Background Hardware skills Software programming skills (C/C++, Java) User interface Computer vision and sensors Interdisciplinary Mandarin - English (presentation, reading, and writing) [We need to select one language in which everyone is comfortable using for in-class discussion] –Why are you interested in this course?
