Why are things so hard to use these days? Why doesn't this thing I just bought work? Why is this website so hard to use? Why is the phone app so confusing? Why do users not like my design? Why is my app not getting popular? These are frustrations that we have all faced from systems not designed with people in mind. The question this course will focus on is: how can we design human-centered systems that people find useful and usable? This course is an introduction to designing, prototyping, and evaluating user interfaces - covering contextual inquiry, task analysis, sketching, human factors, low fidelity and high fidelity prototyping, visual design, usability engineering, usability evaluation and information visualization.
