Introduction to Usability Engineering CS 352 Winter 2018

HW #1 and Design Principles Visibility of user’s options/actions. Feedback Constrain (making certain errors impossible) eg: menus vs typing to prevent syntax errors. (Internal) consistency Affordance makes clear HOW I can do things with an object

Design Activities: Mapped to PRICPE Process Process activities Identify needs/requirements of the user experience. Develop alternative design ideas that meet the requirements. Build prototypes of the designs to communicate/assess. Evaluate iteratively throughout the process. Pre-dispositions Research Insights Concept Prototype Evaluate

In-Class Design Activity Split up into groups of 4-5. You have until 11:30 to design: An on-line “virtual” grocery. Order from home, food arrives. How: Use PRICPE process. Write all your names on the top of the PAPER. Write what you know & what you DON’T KNOW (1st P) on PAPER. In this activity, we’ll skip R, but you might get a few Insights from group discussion. Pick a population & device(s): should help narrow down the 1st P a bit.) When you’re ready, SKETCH Concepts/Prototypes on PAPER. Be ready to argue for why your solution would work for that device/population Aim for creative, interesting, useful solutions Goal: hands-on practice with the design process. We’ll look at a few with the doc scanner.
