1. Introduction to Usability Engineering
CS 352
Winter 2018

2. 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

3. 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

4. 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.
