Accessibility is the design of devices, environments, services, and products for people with disabilities that include a range of physical, sensory, mental, cognitive, developmental or intellectual impairments. In an effort to best provide equal access to physical spaces and environments as well as social, political, and economic resources, accessibility design attempts to offer both direct (unassisted) and indirect (assisted with technology) universal access to the world. Common forms of assistive technologies for humans include mobility technologies such as wheelchairs, prosthetics, walkers, canes, visual technologies like braille and screen readers, auditory technologies in hearing aids and listening devices, and cognitive aids from software to memory devices.
