Paper Prototyping

Quickly visualize basic concepts at an early stage and test them for possible usability problems.

A moderator tells the test person to use the paper prototype like a traditional application and to handle certain tasks. Another person involved in the process of creating the prototype plays the human computer and responds to the user's interaction and input by moving or exchanging the interaction elements. 

The moderator takes on an observational role as the test progresses. By means of a series of photos of the individual processes, a stop-motion film can be created. 
Scissors, paper or printed and cut out interaction and GUI elements
