36 CFR Part 1193 Telecommunications Act (Section 255) Accessibility Guidelines

Paragraph (c)

Compatibility of Controls with Prosthetics

1. Individuals who have artificial hands or use headsticks or mouthsticks to operate products have difficulty with capacitive or heat-operated controls which require contact with a person's body rather than a tool. Individuals who wear prosthetics are unable to operate some types of products because they either require motions that cannot easily be made with a prosthetic hand, or because products are designed which require touch of the human skin to operate them (e.g., capacitive touchscreen kiosks), making it impossible for individuals with artificial arms or hands to operate, except perhaps with their nose or chin. Some individuals who do not have the use of their arms use either a headstick or a mouthstick to operate products. Controls and mechanisms which require a grasping and twisting motion should be avoided.
