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 2

Design Activities: Mapped to PRICPE Process Process activities (See ch. 1) –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. 3 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 any lists/notes (1 st 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). –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. 4
