5. Contact Info Email is the best way to contact the teaching team: –me (sharrison@cs.vt.edu) –Dr. North (chnorth1@vt.edu) –Kibum (kikim@cs.vt.edu) Section 1 CRN 11499 TuTh 5:00-6:15kikim@cs.vt.edu Web page ( courses.cs.vt.edu/~cs3724 ) contains lecture outlines, assignments, and related materials

6. Adminstrivia Force-adds and prerequisite forms –CRN is 11499 –Prerequisite is CS 2604 –Everyone must complete one of the forms –Must attend today –Add decisions by next meeting Background surveys –Used to place people on teams –Confidential –Does not affect grade

7. Goals of Course (official version)  Survey of human-computer interaction concepts, theory, and practice.  Interdisciplinary underpinnings.  Informed and critical evaluation of computer- based technology.  User-oriented perspective, rather than system- oriented, with two thrusts: human (cognitive, social) and technological (input/output, interactions styles, devices).  Design guidelines, evaluation methods, participatory design, communication between users and system developers.

8. Goals of Course (Steve Harrison’s version)  Learn that HCI topic is both wide and deep.  HCI is essentially about design and design involves asking good questions  Convince some of you that HCI is phat / cool  Convince the rest of you that HCI expertise is needed in most computer projects

9. HCI and UE Analyzing, designing, and evaluating activities which typically involve one or more humans interacting with (or through) computing systems to accomplish one or more tasks.

10. A Method: Scenario-Based Usability Engineering Stories of people and their activities Typical elements of the story are: –A setting –One or more actors or agents –An orienting or motivating goal or objective –Mental activity, plans or evaluation of behavior –A “storyline” sequenced by actions and events Emphasis on use, i.e., people’s needs, expectations, actions, and reactions

11. Problem scenarios summative evaluation Information scenarios claims about current practice analysis of stakeholders, field studies Usability specifications Activity scenarios Interaction scenarios iterative analysis of usability claims and re-design metaphors, information technology, HCI theory, guidelines formative evaluation DESIGN ANALYZE PROTOTYPE & EVALUATE

12. Course Overview Lectures, videos and activities Individual homework assignments Readings Tests Hall of Fame / Hall of Shame Design project

13. The Project Team-based (but you already heard that) Choose from two themes –Information vizualization –College of Engineering community information Problem seeking / problem solving Find users & problem, prototype, interim review presentation, evaluate, revise, final presentation C# language

14. Textbook Mary Beth Rosson and John M. Carroll, Usability Engineering: Scenario-Based Development of HCI
