The following broad topic areas will be covered by Exam 2 which will be 50 minutes long. Refer to the course slides and textbook for more details about what you should know in a topic area.
The exam will have short answer style questions, and longer questions where you will carry out a process, design, or evaluation activity similar to ones that you did as exercises or term project activities. There will not necessarily be questions on every topic described below on your exam.
UX Design
Design paradigms: what are they; what is design thinking; design thinking tools, emotions, persona, ideation, and sketching.
Design activities: conceptual design, what is it and how to create it, mental model perspectives, metaphors, and storyboards; intermediate design, what is it, how to create it; detailed design, what is it, how is it different from intermediate deign; wireframes, what are they used for, what do they consist of, what information do wireframes show; prototyping, what is it, types of prototypes, fidelity of prototypes .
Affordances: its meaning in the context of interaction design; physical affordances and Fitts' law; cognitive affordances; sensory affordances; functional affordances; emotional sffordances.
Design guidelines: execution/evaluation action model, stages of action; explain the model; how it is used to structure design guidelines; what design guidelines support the different stages of action; how these guidelines support usability goals.
UX Evaluation
UX evaluation: formative evaluation, summative evaluation, purpose of each, and when to use them; methods to collect data, and evaluate emotional impact .
Rapid evaluation: cognitive walkthrough (CW), what is it used for, how to prepare for CW, what data we collect and how this data is analyzed and used, different roles in CW; heuristic evaluation (HE), its purpose, how to conduct it, data collection and analysis, different roles in HE, Nielsen's heuristics.
Rigorous evaluation (usability testing):
What is it; its pros and cons
Ethical considerations
Test plan
Logistics: schedule, location, equipment
Participants recruitment
Test team roles
Design the test
Define the measurements based on the UX goals
Measuring instruments, which can be tasks (write task scenarios), or survey (prepare the questions)
Decide what quantitative data you will collect e.g. time on task, rate of success
Decide what qualitative data you will collect e.g. subjective feedback from participants, test team observations
Test script
Evaluation analysis: analysis of usability test data both quantitative and qualitative; outliers, their meaning and how to deal with them; possible reasons for errors in testing; task and error analysis; statistical analysis e.g. mean, median, and correlation.
