This document outlines a workshop on paper prototyping user interfaces. It will cover creating paper prototypes, conducting usability testing with paper prototypes, and a discussion. Attendees will have time to create their own paper prototype and test it. The document provides details on the benefits of paper prototyping, such as getting early feedback with minimal effort. It also explains how to create various elements of a paper prototype like screens, movable elements, and interactions. Guidelines for testing paper prototypes are also included, such as creating tasks and having different people take on the roles of participant and facilitator/computer.
