Low-Fidelity Prototyping

A design method that uses simple, inexpensive materials to create quick, rough representations of a product or interface for early-stage testing and feedback. Traditional lo-fi prototyping relies heavily on visual methods such as sketches, storyboards, and paper mockups, which creates significant accessibility barriers for blind and low vision participants. Adapted lo-fi prototyping for blind users can incorporate tactile materials such as 3D-printed elements, magnetic boards, embossed paper, clay, and foam to enable non-visual design exploration. The method is valuable for involving end users early in the design process before committing resources to detailed development.
