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 (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.

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 (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).– 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
