AUTOMATED:

From "What you should know about prototypes for user testing"
Automated prototypes allow users to make choices that cause changes. The testing prototype provides the user with feedback. Elements are “clickable” and forms can be filled out. The interface reacts to the user while the tester observes. One way to do this is to create the prototype in HTML or some application that allows interactive elements such as Flash, Visual Basic or even PowerPoint. Another way to achieve a kind of pseudo-automated interactivity when you have chosen a paper prototype is to pretend.
