A tool to support the understanding of what happens during the testing of a prototype by taking notes on its actors and interplay: how people react, what they do and what they say. It allows to get a perspective on what is happening, what’s going on in a specific environment.

The tool works as a guide for an individual researcher or a group of researchers. For getting a complete picture, it is recommended to conduct more observations, since various perspectives, behaviours, attitudes may emerge through time.
