1. Semester wrap-up …my final slides.

2. More on HCI Class on Ubiquitous Computing next spring Courses in visualization, virtual reality, gaming, etc. where HCI plays a role Research I have projects in HCI and Ubicomp

3. The Final May 11, 7pm - 10 pm Closed book, one page of notes Cumulative Similar format to midterm (probably about 50% longer)

4. Other stuff Peer rating – rate you and your group members contributions to the project Feedback for me

5. 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

6. 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

7. 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

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

9. 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

10. 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

11. Exam topics, cont. Ubicomp What are examples? What are challenges? Special topics – high level understanding Privacy Multi-modal interfaces 3D user interfaces Context-aware computing Conversational agents Visualization

12. 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? What is a paradigm shift? Is ubiquitous computing a paradigm shift? Defend your answer.
