Low-Fidelity Prototype

A rough, inexpensive representation of a design - typically paper sketches, cardboard models, or wireframes - used early in the design process to explore concepts without investing in polished artefacts. Low-fidelity prototypes lower the barrier to critique and change, which is particularly valuable in co-design with people with intellectual or cognitive disabilities: their incompleteness invites contribution, reduces intimidation, and allows co-designers to physically manipulate and reshape ideas rather than passively evaluating a finished product.
