For people living with severe motor disabilities such as Amyotrophic Lateral Sclerosis (ALS), spinal cord injury, or cerebral palsy, traditional QWERTY touchscreens quickly become insurmountable physical barriers.
Tania Finlayson and the Genesis of Gboard Morse
Born with spastic cerebral palsy, Tania Finlayson was non-verbal until her husband Ken and an occupational therapist introduced her to a custom Morse code computer system. By tapping two switches with her head, Tania could spell words at up to 35 words per minute. Her collaboration with Google Accessibility engineers led to the official release of the Gboard Morse Code keyboard, bringing universal AAC (Augmentative and Alternative Communication) capabilities to billions of smartphones.
“Morse code gave me freedom and a voice. Bringing it to Google Gboard meant anyone anywhere could download a free communication lifeline.”
The Engineering Superiority of Binary Morse over Virtual QWERTY
Virtual keyboard eye-gaze and single-switch scanning require users to wait for highlighting grids to scan through rows of 26 letters, resulting in slow communication rates of 2–5 words per minute. In contrast, two-switch Morse code acts as an immediate binary tree traversal. Each letter requires only 1 to 4 conscious motor impulses, quadrupling communication velocity and dramatically reducing cognitive fatigue.
Eye-Gaze Dwell Typing: 4–8 WPM | Single-Switch Row/Column Scanning: 3–6 WPM | Two-Switch Morse (Gboard): 15–30 WPM with predictive AI completion.
Open-Source Hardware and Physical Switch Integration
Gboard Morse works with standard 3.5mm assistive switches plugged into Android USB accessibility adapters or Bluetooth HID switch interfaces. Operators can customize dot-dash timing thresholds, visual feedback ribbons, and acoustic sidetones to accommodate tremors and spastic muscle reflexes.
