The International Day of Persons with Disabilities – Mathematics of Accessibility

Mathematics improves accessibility: speech‑recognition algorithms (Markov models), screen readers (text‑to‑speech – signal processing), and wheelchair‑friendly route planning (graph theory with weighted edges for slope). The ‘curb cut effect’ – designs for one group benefit everyone. Mathematical optimisation of building layouts (e.g., elevator placement) uses constraints (disabilities). Inclusion is an optimisation problem: maximise access subject to cost constraints. Math can break down barriers when applied with empathy.
