IEEM 552 - Human-Computer Systems

1. IEEM 552 - Human-Computer Systems Dr. Vincent Duffy and Dr. Richard So Lecture 1: An Overview and Selection of Papers Wednesday September 5, 2001

2. Introduction and webpage • An Introduction • two videos from CHI 2001- Seattle, USA • Digital jewelry: Wearable Technology for everyday life - IBM Research Group - 39:29. • Exploring 3D Navigation: Combining speed-coupled flying with object orbiting - Microsoft Research - 2:00 • Dr. Vincent G. Duffy, IEEM and Dr. Richard H.Y. So • Assistant for the course : Gilbert Leung Tin Chak email: gilbert@ust.hk • Course webpage • http://teaching.ust.hk/~ieem552 • there you can find course syllabus and today’s notes

3. Classroom format • About half of each class: lecture Human-Computer Systems issues • and ergonomics fundamentals as they relate to human-computer systems • About half of each class: Discussion and analysis of research cases related to current topics • students in the class will present the articles as they understand them. • We will give some guidance for things to consider in the presentations • strategies for looking at research articles

4. Aims and objectives • Aims: • To examine the human aspects of human-computer systems • and apply the knowledge to design, evaluate, and integrate successful human-computer systems. • After this course, students should be able to: • identify potential problems associated with a human-computer system and propose solutions to improve it. • evaluate the benefits of human-computer systems in terms of productivity as well as impacts on the social and organizational aspects. • apply the latest research related to human-computer systems improvement.

5. What do you expect to gain from this course? How can an understanding of Human-Computer Studies benefit you? • Consider usability • systematic approach • Emphasis on process as well as applications • focus on learning how to • gain understanding about... • usability and human subjects testing - experimentation • After this course, you should be able to think beyond the functional requirements • cognitive, physiological and organizational aspects of Human-Computer Systems

6. Meeting time and course text • Lectures: Wed., 16:00 - 18:50, Rm1402 • Office hours: Monday to Friday and appointments via email • Course Text: • An Introduction to Human Factors Engineering, Christopher D. Wickens, Sallie E. Gordon, and Yili Liu, Addison-Wesley Longman, Inc, New York, 1998, 636 pages.

7. Supplementary reading and grading • Supplementary Reading: • selected articles from academic journals and conference proceedings will be available in a folder • these readings will be presented and discussed in class. • Course Grading: • Mid-Term Exam 25% • Open-book exam • Case discussion-presentations 40% • Project 20% • Participation 15% • 100%

8. Previously - in 1999…when I last taught this • Main focus - book from 1994 • User Interface Design by R. Eberts • Management in aspects of H-C systems - real world cases • Usability principles, Menu displays. • Methods for testing effectiveness, mental workload measures. • Hazards in conducting and interpreting HCI studies. • Introduction to Interface Design and Visual C++/VB. • However the field is much broader now. • As we get into the semester I hope you will see what I mean. • For the most up to date work in the field • the two premier conferences will give you some insights into what is happening.

9. HCI International 2003 - Crete, Greece http://hcii2003.ics.forth.gr

10. ACM-CHI Conference on Human Factors in Computing Systems -Minneapolis, USA, April 2002http://www.acm.org/sigchi/chi2002/

11. The field is much broader now. • That book by Eberts is now nearly 8 years old • it seems quite outdated when you consider a ‘systems’ view that is needed in many human-computer applications. • You will notice that more than 60% • (25 of 40 supplementary readings) are either from • 2000 or 2001 • That is... • these articles were written and published AFTER I last taught the course in 1999.

12. Week by week

13. Week by week

14. Selected readings included in the syllabus • Come from various important books, journals and conferences • Introduction to Human Factors Engineering • Handbook of Human-Computer Interaction • Handbook of Industrial Engineering • Handbook of Human Factors and Ergonomics • Fundamentals of Wearable Computers & Augmented Reality • Universal Access in HCI • Human Factors in Intelligent Transportation Systems • Cognitive Task Analysis • Stress, Workload and Fatigue

15. Selected readings included in the syllabus (cont.) • Int. J. of Human-Computer Interaction • Int. J. of Industrial Ergonomics • Behavior and Information Technology • IEEE Transactions on Systems, Man and Cybernetics • Human Factors • Ergonomics in Design • Int. J. of Medical Informatics, • Int. J. of Man-Machine Studies • Int. J. of Human-Computer Studies • J. of Intelligent Information Systems • User Access in the Information Society • Various IEEE, ACM and HCII conferences

16. Selection of papers • All students should plan for 3 presentations • At least one will be done alone. • One or two will be done in teams of 2 students per paper. • We will begin the selection today. • All students: Please choose one paper and sign up • After all students have chosen one paper, we will have round 2 selections (then round 3). • You must choose a paper that is not selected before we can begin to choose a paper for the second time. • Please note the number of slots is the maximum number of people that can present the paper

17. Things to consider for presentation • 1. Objective of the research • 2. Brief discussion of literature support • 3. Development of hypotheses (if any) … or why the research was done in this way • 4. Methods • 5. Results • 6. Discussion/conclusions • any practical application for the research? • Theoretical contribution? • 7. Future work: any suggestions?

18. 10 ways to look at a research paper systematically for critical analysis • 1. research ideas/question -what is the purpose? • 2. what background support? - literature review • 3. theoretical basis for analyzing question/hypothesis? • 4. applicability-practical contribution? • 5. theoretical contribution? • 6. appropriate methodologies for carrying out study? (determining variables, data collection, method used to test hypotheses, validity of measures and reliability) • 7. appropriate statistical analyses and assumptions? • 8. presentation of results: what do they really mean? • 9. conclusions drawn: are they reasonable? • 10. future work/research directions: any possibilities?
