Topics
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
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

A message from NSC
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
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
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
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
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?
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
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)
