Christy runs her computer with a single head switch. This is where she learns Morse code — so that one small movement, short or long, can become any word she wants to say.
Most ways of controlling a computer assume you can make many different movements — reach dozens of keys, glide a mouse, tap around a screen. A single switch can't do that. So most single-switch users rely on scanning: a highlight crawls across rows of letters, and you press when it reaches the one you want. It works, but it makes you wait. The machine sets the pace, and you catch it.
Morse code turns that around completely. Every letter is built from just two things: a short press (a dot) and a long press (a dash). One switch can make both. And because you send the letter the instant you think of it, you set the pace — never the machine. There is nothing to wait for.
Researchers who study computer access call Morse the one input method that can become sub-cognitive — fully automatic, like a touch-typist's fingers or a drummer's hands. Past the learning stage, you stop thinking about dots and dashes and simply think the word. Switch users routinely reach 15–30 words per minute this way, and it tends to be less tiring than scanning, because it's a rhythm you produce rather than a highlight you chase.
Learning a rhythm skill takes more than one kind of help, so the system has three parts — each doing the job it's best at.
A browser app that listens to her switch and teaches the alphabet through practice, with instant feedback and a built-in communicator. This is where the skill is actually built.
Short audio episodes that explain what Morse is, tell the story of the people who made it a voice, and walk through each lesson — motivation and meaning, in plain words.
The same material as printable sheets — good for a helper to read, and good for the letter chart to go up on the wall next to the computer.
The reason they're separate matters, and it's covered further down — but the short version is that sending Morse is a motor skill (that's the trainer's job) while understanding and staying motivated is a story (that's what the shows and guides are for). Neither can do the other's job well.
Off-the-shelf Morse trainers assume a typical, steady hand and standard timing. That assumption is exactly what fails a person with cerebral palsy. This trainer was built the other way around — it bends to fit her.
The trainer treats any keyboard key, and any click on its big keying area, as the switch. Her switch interface already turns a head press into a keystroke or click, so the trainer hears it with no special drivers, no pairing, no marriage between programs. If a helper can make a character appear in Notepad, the trainer will hear the switch.
Before the first lesson, she makes five comfortable short taps and five comfortable long presses. The trainer measures her presses and sets the dividing line between dot and dash right inside her natural rhythm — not at some ham-radio standard she'd have to strain to hit. If a tired day changes her timing, calibration takes thirty seconds to redo. The tool fits her; she never has to fit the tool.
While she holds the switch, an amber bar grows. The moment it crosses the marked line, her press has become a dash and the bar changes color to say so. In the early days she watches it; soon her body knows the difference between short and long without looking, the way you learn the weight of a light switch in the dark.
Every press prints onto a scrolling paper tape — a round dot for short, a long bar for long — exactly like the ribbon that ran out of a real telegraph in 1844. When a letter finishes, it prints beneath the marks. She watches her own words appear, correct ones in green, so feedback is immediate and never scolding.
The alphabet is taught in eight small lessons, easiest and most common letters first: E and T are a single press each. Within minutes she keys her first real word. Each letter is "mastered" after three correct sends, then the next unlocks — and practice words are built only from letters she already knows, so she's spelling real things almost immediately. A miss costs nothing: the trainer just replays the rhythm and waits.
This is the whole point. On the Type & Speak page she keys anything she likes, and the computer says it out loud in its own voice. A longer rest adds a space; six quick dots erase a letter — the old telegraph operator's "scratch that." After Lesson 7 she'll have every letter in I LOVE YOU. The trainer reminds her to key it with someone she loves in the room.
The whole trainer is one file that works offline. No accounts, no internet required at practice time, nothing to break on a bad-connection day. Progress saves on the computer, with a copy-paste backup code. For an assistive tool that someone leans on daily, reliability beats features — so it was built simple on purpose.
Cerebral palsy can make timing variable. Because the trainer calibrates to her own presses, that variability stops being a wall and becomes just a setting to adjust.
No highlight to chase, no scan to wait for. The letter arrives the instant she thinks it. Speed becomes hers to grow, not the software's to ration.
The real prize. With daily practice the code fades from conscious thought, and she's left simply talking — thinking a word and having her head produce it.
What she learns here isn't trapped in a trainer. The same dots and dashes drive real devices — like the TandemMaster and Darci USB — that turn one switch into a full keyboard and mouse for any program.
Tania Finlayson was born with cerebral palsy, cannot speak, and has used head-switch Morse code as her voice for most of her life. She went on to help Google build Morse into the keyboard on millions of phones, so the next person would have an easier start. The destination isn't a trainer or a lesson — it's the whole computer answering to her rhythm. This is simply the first mile of that road.
None of the structure is decoration. Each decision answers a specific thing about learning a rhythm skill with a single switch.
A motor skill is built by doing (the trainer), but effort needs feeding by meaning and story (the shows), and a helper needs something to hold and post on the wall (the guides). Splitting them lets each be excellent at its one job instead of mediocre at three.
The hardest stretch of learning Morse is the middle weeks, where most people quit. Front-loading quick wins — real words in the first session — builds the momentum that carries a learner through that middle. The order isn't alphabetical; it's motivational.
Standard Morse timing is tuned for typical motor control. Starting every learner by measuring their own short and long presses means the trainer never asks her to strain toward someone else's rhythm. It's the single most important thing generic trainers get wrong for someone with CP.
An assistive tool used every day has to work on the bad days too — spotty internet, a locked-down machine, a browser that won't cooperate. Keeping the trainer a single self-contained page that runs offline is a feature in itself: it's always there.
You can't learn to send Morse by listening — that's muscle memory, and only the trainer's reps build it. But you can't stay motivated on reps alone — that's where the story of what you're doing, and why, belongs. The audio shows carry the meaning so the trainer can stay focused on the doing.
Start with Episode 1 for the story, or go straight to the trainer and key the first letter. The tape is waiting.
