Paper Prototype
Noun · Hacker Culture
Definitions
A low-fidelity prototype made with sketches or printed screens to test interface ideas, flows, or user reactions before investing in full implementation. It is common in design work because it makes iteration cheap and keeps discussion focused on structure rather than polish.
In plain English: A rough prototype made on paper to test an idea before building it.
Example: "The team caught the navigation confusion early because the paper prototype made the flow obvious."
