PDF Prototypes: Mistakenly Disregarded and Underutilized: „Creating a clickable PDF to prototype a new design is not a new concept, but it is a valuable tool that is often overlooked and underutilized. While working over the years with other designers, information architects and usability professionals, I’ve noticed that many of my colleagues believe the same fallacies about the limitations of PDFs. Contrary to popular belief, you can do more than just create links and interactive forms with PDFs; you can also add dynamic elements such as rollovers and drop-down menus, embed audio and video files, validate form data, perform calculations and respond to user actions. PDF prototypes have the ability to replicate most interactive design elements without investing a lot of time and effort.“
