The document introduces POP (Prototyping on Paper), a tool that allows users to turn hand-drawn sketches into clickable prototypes. It recommends sketching out screens and getting feedback from friends through user testing. The tool can be found on the App Store and more information is available at go.osu.edu/popapp. Users are encouraged to disclose their ideas to the Technology Commercialization Office (TCO) for assistance in making their sketches interactive.
