Design Analysis of Everyday ObjectsReviewAssignmentSlide 4Slide 5Slide 6Slide 7In-Class PresentationSummaryDesign Analysis ofEveryday ObjectsIS 485, Professor Matt Thatcher2ReviewDesign for improved usabilityDesign model should match user modelNorman’s design guides–make things visible»affordances»crucial distinctions»constraints –provide good mappings and interface metaphors–provide feedback3AssignmentThe purpose of this assignment is to evaluate the usability of “everyday objects” Each student will bring an “everyday object” from home to class–try to bring an object that causes you great frustration or an object that you really like and think is well-designedIn class we will break up into groups of 4 and evaluate/analyze the usability of each student’s “everyday object”4AssignmentGet out 2 sheets of paper–put your name, and the object’s name at the top of each sheet–title 1 sheet “Good Design Elements” and the other “Bad Design Elements”Make three (3) columns on each paper (see next two slides for examples)–title column 1 “Visibility”–title column 2 “Mappings and Metaphors”–title column 3 “Feedback” –pass each object (and the 2 sheets of paper) to each member of the team567AssignmentAnalyze each object in terms of Norman’s framework (or the heuristics)Each member should write at least three comments (good, bad, or both) about each object on the papersThese papers will be turned in!!8In-Class PresentationVolunteers will present their objectsTell us:–what are the good design aspects?»e.g., good visibility, mappings and metaphors, and feedback»explain why they are good–what are the bad design aspects»e.g., poor visibility, mappings and metaphors, and feedback»explain why»make a specific recommendation on how to improve the designTalk for about 3-5 minutes9SummaryBad UI design surrounds us–it’s in everyday objects and software applicationsBad UIs lead to poor usability and make:–systems difficult to learn–systems difficult to remember –users less efficient–users more prone to make errors–users less satisfiedUser-centered design can help–better understanding of users and their mental models leads to better design decisions / improved
