Curb-Cut Effect

The phenomenon whereby features designed for people with disabilities end up benefiting a much broader population. Named after pavement curb cuts originally mandated for wheelchair users, which also help parents with pushchairs, delivery workers with carts, cyclists, and travellers with wheeled luggage. In technology, the curb-cut effect is widely observed: closed captions designed for deaf users benefit people in noisy environments or learning a language; voice control designed for blind users helps drivers and people with full hands; readable website design for people with dyslexia improves comprehension for everyone. The curb-cut effect is a powerful argument for accessibility investment, demonstrating that inclusive design creates value beyond the disability community.
