3. Topics

4. Evolution of HCI ‘interfaces’ (1/2) 50s - Interface at the hardware level for engineers - switch panels 60-70s - interface at the programming level - COBOL, FORTRAN 70-90s - Interface at the terminal level - command languages 80s - Interface at the interaction dialogue level - GUIs, multimedia

5. Evolution of HCI ‘interfaces’ (2/2) 90s - Interface at the work setting - networked systems, groupware 00s - Interface becomes pervasive, disappearing, and invisible in a way –The world is the interface itself –How to realize this? sensor technology, mobile devices, consumer electronics, interactive screens, embedded technology

6. From “Resource-Centric” to “User-Centric” Past Super Distribution Are the clients satisfied? Please give me… Servants for human and society. Java I like… -Logic-aware -Resource centered -Context-aware -Resource distributed Resource Adopt from: “Context-Aware & Yet Another service” Hiromitsu Kato, ubicomp2002 Systems Development Lab.

9. Course objective and format (1/2) This is mainly a graduate level, research (seminar) oriented course Go through a light-weight research cycle within one term Collaborative learning - students and faculties

10. Course objective and format (2/2) Traning in technical paper reading and critical thinking –Paper reading Define problems and challenges Understand state-of-art techniques and solutions Identify limitations of state-of-art solutions –Paper presentation and discussion –“Project idea presentation” 5~6 papers on a specific topic/week –Review for each paper before the class –20mins for paper presentation –10mins for paper discussion

11. My role in this course Facilitate your learning –will not presume to “teach” you everything –you will learn most by reading, thinking, listening to and challenging your fellow classmates, and doing Help you consume papers Try best to help stimulate critical thinking Help you form the base for future research in this area

12. How to “consume” and “attack” a paper? (1/2) For each paper, try to answer the following questions: –What is the problem? –What is the most up-to-date solutions? –What is the key (new) method and technique? –What is good or bad about this method? –What has actually been done? Adopt from Hao-Hua Chu’s Teaching Experience Sharing in Ubiquitous Computing Course

13. How to “consume” and “attack” a paper? (2/2) Challenge what you read –Are assumptions reasonable? –Is the method similar to other methods in related work? –Is the improvement marginal or significant? –Are arguments logically sound? –Are evaluation metrics reasonable?

14. Light-weight research cycle (1/2) Drama: define motivation scenarios (Tell an interesting and attractive story) –Emphasize the parts of a scenario where it is currently not possible, but with your idea, it will become possible. Derive problem(s) –Assumptions (research problems), requirements, implementation

15. Light-weight research cycle (2/2) Survey related work Design solution(s) (new method and concept) –Differentiate your work from related work –Must answer two questions: What ’ s new? Why is it significant? –Rapid prototyping –Evaluation of Prototype Implementation (Experiments, user studies)
