"Paper prototyping is a variation
of usability testing where representative users
tasks by interacting with a paper version of the
that is manipulated by a person ‘playing computer,’
who doesn’t explain how the interface is intended to
work."– Snyder, 2003
So what does that mean? You can develop a very low resolution model of an interface you're designing and be able to have a real user interact with it and give you feedback about it without having to implement anything digitally. You can change things on-the-fly and iterate rapidly on paper before committing anything to code and pixels.
Materials: Whiteboard, Post-its, Markers (can also be done with sheets of paper or just a whiteboard/chalkboard
1st iteration (5 min): Students choose a topic around which to create a prototype. If you are working on a challenge as a class you can use whatever you came up with in the ideate step of the process, if teaching the lesson as a stand alone, use something simple like "Design a web interface to design sunglasses" or "create a pair of shoes for your partner""design a cool bedroom for one of your classmates." Spend 5 minutes developing a quick prototype using post-its on the whiteboard.
Feedback (5 min): Have students present their ideas to a test group (usually one another) for feedback, using the paper prototype as visual aide.
Iterate (5 min): Have students go back to their paper prototype and make changes based on the feedback they received from their test group.
Wrap Up (5 min): Ask the following questions as a quick wrap-up. What did you learn about your idea from the rapid prototyping? What did you learn about the overall process? What are the benefits of this kind of prototyping? What are the limitations?
