You can create paper prototypes as well as computer-based interactive prototypes. Creating these prototypes should be quick, not final design. The prototype is given to users who are told the story (realistic) and then given the task to perform using the product (prototype). As soon as the user begins to take action on the prototype, everything is documented (deviations from the red line – specific locations where unwanted actions were observed). It is desirable for the user to “think aloud”, which allows them to record what emotions and thoughts the user has at the time of use. You can create an Empaty Map and a User Journey & Emotion Map by gathering all the information.

We recommend using a microphone or a video camera to document everything you observe during the test.
