1. Semester wrap-up …the final slides.

2. The Final  December 13, 3:30-4:45 pm  Closed book, one page of notes  Cumulative  Similar format and length to midterm

3. Other stuff  Peer rating – rate you and your group members contributions to the project  Feedback for me  Please bring to final!

4. Course ReCap  To make you notice interfaces, good and bad You’ll never look at doors the same way again  To help you realize no one gets an interface right on the first try Yes, even the experts Design is HARD  To teach you tools and techniques to help you iteratively improve your designs Because you can eventually get it right

5. Recall: exam topics  Requirements What are they? Data gathering techniques – when and why? User and stakeholder characteristics Scenarios and personas  Task analysis HTA Other methods for describing tasks

6. Exam topics, cont.  Design General purpose and process Norman’s principles (affordance, mapping, conceptual model, etc.) Execution-evaluation cycle General usability principles (learnability, flexibility, robustness) Errors – mistakes and slips Visual design – basic principles and lessons Web design – special issues for the Web

7. Exam topics, cont.  Prototyping and storyboards  Evaluation Characteristics of evaluation techniques Predictive – Fitt’s, Hick’s KSLM What are techniques? When to use which techniques? Advice, guidelines for using techniques

8. Human abilities  Good Infinite capacity LTM LTM duration & complexity High-learning capability Powerful attention mechanism Powerful pattern recognition  Bad Limited capacity STM Limited duration STM Unreliable access to LTM Error-prone processing Slow processing Memory, cognition, learning, problem solving

9. General Issues in Choosing Dialogue Style  Who is in control - user or computer  Initial training required  Learning time to become proficient  Speed of use  Generality/flexibility/power  Special skills - typing  Gulf of evaluation / gulf of execution  Screen space required  Computational resources required

10. Exam topics, cont.  Groupware Classification matrix Challenges in building and evaluating  Assistive technology How do various disabilities effect use of technology? What are examples of technology or designs that can help?  Ubicomp What are examples? What are challenges?

11. Sample questions What usability property of a system is the main focus for a cognitive walkthrough evaluation method? What four questions make up the believability story for a cognitive walkthrough? T/F A cognitive walkthrough is a good technique to observe experts performing tasks and interacting with the system. T/F A good menu design consists of 7 +- 2 options.

12. More sample questions The use of a percent done indicator is an example of what Norman principle affordance/mapping/feedback/conceptual model Compare and contrast think aloud and cooperative evaluation Describe two challenges interface designers face that are particular to Web design
