Assistive Technology & MND
Technology can preserve communication and independence when MND takes away movement and speech. The tools that help, and the famous system that gave Hawking his voice.
Last updated 23 May 2026 · How we research
When motor neurone disease gradually takes away movement and speech, assistive technology can preserve something precious: the ability to communicate, work and stay connected to the world. This page gives a general overview of the tools available and of Hawking's own famous setup. It is background information, not a clinical recommendation; the right equipment is best chosen with a specialist team.
Communication aids
The broad field of communication aids is known as augmentative and alternative communication, or AAC. It ranges from simple letter and word boards a person can point to or look at, through to sophisticated computer systems that speak aloud. Crucially, these systems can be operated even by people with very limited movement, using whatever reliable motion remains: a finger, a head movement, a single muscle, or, increasingly, eye-tracking that lets a person select letters just by looking at them.
Modern systems use word prediction to speed things up, suggesting likely words after a few letters, much like a smartphone keyboard, which can dramatically increase how quickly someone can "speak."
Hawking's system
Hawking is the most famous user of this kind of technology in history. After losing his voice in 1985, he selected text using a small movement of his cheek to operate a switch, with software that scanned through options and predicted words. In his later years this was developed, with help from engineers at Intel, into a custom system designed to make the most of the very limited movement he retained. Through it he continued to write books, publish research and lecture around the world.
Beyond communication
Assistive technology also supports independence in daily life, through powered wheelchairs, environmental controls that operate lights, doors and devices, and emerging brain-computer interfaces being researched for the future. Together, these tools cannot stop the disease, but they can protect a person's voice, work and autonomy, as Hawking's own life showed so powerfully. For more on daily life, see living with MND.
If you or someone close to you is affected by MND, the MND Association offers information and support. You can find ways to help on the support page.
