Electronic Curb-Cut Effect

The phenomenon where accessibility features originally designed for people with disabilities end up benefiting a much wider population. Named after physical curb cuts in sidewalks — originally mandated for wheelchair users but widely used by people with strollers, delivery carts, and bicycles — the electronic curb-cut effect describes how digital accessibility innovations frequently prove useful to people without disabilities. Examples include closed captions benefiting viewers in noisy environments, voice interfaces helping drivers, and auditory descriptions supporting language learners. This principle is a key argument for universal design and for investing in accessibility features broadly rather than narrowly targeting specific disability groups.
