What is a keyguard used for in assistive technology?

A keyguard is an assistive technology device designed to help users accurately select keys on a keyboard. It consists of a rigid overlay that has openings for the keys, which helps prevent accidental key presses by providing a physical barrier. This is particularly beneficial for individuals with motor control difficulties, as it allows them to focus on pressing the correct key without the risk of hitting adjacent keys, improving their typing accuracy and efficiency.

The functionality of a keyguard is especially critical for users who may have limited fine motor skills, such as those with conditions like cerebral palsy or after a stroke. By enhancing the precision of key activation, keyguards facilitate effective communication and data entry for individuals who rely on computer access for their education, work, or daily activities.

In contrast, other options do not address the primary purpose of a keyguard effectively. Improving auditory feedback pertains to auditory devices, promoting visual stimulation relates to visual aids, and providing a tactile surface serves a different purpose entirely, mostly benefiting those with visual impairments rather than supporting accurate key presses.
