Keyguards are a form of assistive technology designed to help people carefully select or focus on the desired keys and avoid inadvertently selecting or being distracted by surrounding keys or elements.
They are typically plastic or metal, and they can be pre-manufactured or customized to users' specific needs or devices.
Depending on the device type or the reason for use, they are available in a variety of attachment modes, opening spacings, and opening placements. They can rest on top, clip on top, or snap within a device; be secured by magnets; limit access to portions of screens or input devices; feature larger or smaller openings; and other variations. Custom-made keyguards feature more options for personalization.
Keyguards have been used to help with augmentative and alternative communication (AAC), motor precision, and other applications where more exact or intentional input and interaction is beneficial or required.
