Paper Prototypes
Paper prototypes are low-fidelity, hand-drawn sketches or mockups of user interfaces created on paper or similar physical materials to simulate and test design concepts early in the development process. They are used in user experience (UX) and interaction design to visualize layouts, workflows, and interactions without investing in detailed digital implementation. This method allows for rapid iteration, user feedback, and validation of ideas before moving to higher-fidelity designs.
Developers should learn and use paper prototypes during the initial stages of software or app development to quickly brainstorm and test interface ideas with stakeholders or users, reducing the risk of costly changes later. It is particularly valuable in agile or lean development environments where iterative feedback is crucial, and for projects with unclear requirements or complex user interactions that need early validation. This approach fosters collaboration, encourages creativity, and helps identify usability issues before coding begins.
