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 Pre-dispositions – Identify needs/requirements Research • of the user experience. Insights – Develop alternative design ideas Concept • that meet the requirements. Prototype – Build prototypes of the designs • to communicate/assess. – Evaluate iteratively Evaluate • throughout the process. 3
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 (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): should help narrow down the 1 st 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. 4
