Keyguard

A rigid cover that fits over a keyboard with holes aligned to each key, allowing users with motor impairments to rest their hands on the surface without accidentally pressing keys. Keyguards help people who have imprecise motor control, tremors, or involuntary movements to type more accurately by providing a physical guide to each key location. They can be made from acrylic, metal, or 3D-printed plastic, and are available for both physical keyboards and tablet screens. Commercial keyguards can be expensive, but 3D printing has made it possible to produce custom-fitted, low-cost alternatives tailored to individual needs and specific keyboard models.
