Apraxia-friendly AAC: why touchscreens fail, and what helps
Plenty of families try a communication app, watch it not work, and conclude that AAC "isn't for" their child or sibling. Very often the app was never the problem — the touchscreen was. This page explains why, and what to look for in an AAC app when apraxia or other motor difficulty is part of the picture.
What apraxia does to tapping
Apraxia affects motor planning — the path between deciding to do a movement and the body carrying it out. On a touchscreen that shows up in familiar ways: taps that land next to the intended key, a finger that rests a moment too long and fires a key twice, a drag that registers as a tap, or a touch that lands on the way to somewhere else. None of that says anything about what the person knows or wants to say. It is a hands problem, not a knowing problem.
Standard AAC apps are usually dense grids of small picture buttons. Every extra row makes each target smaller, and every mis-tap speaks the wrong word out loud — so the app itself keeps interrupting with errors the person never meant. For someone who already knows their letters, there's a second cost: a symbol grid caps them at the words someone else chose to put on the board.
What an apraxia-friendly AAC app changes
Four things matter most, and they're worth checking in any app you try:
Big, well-spaced targets. Fewer, larger keys mean a tap can be imprecise and still land. A letterboard-style layout — 26 letters plus a few controls — keeps every target large on a tablet screen.
A tap guard. Accidental repeat taps (the double-fire when a finger lingers) should be absorbed by the app, not spoken aloud. TBoard's tap guard ignores repeat taps inside a window you control.
Touch or lift to select. TBoard can select a letter when a finger touches the key or when it lifts. Its adjustable tap guard ignores accidental repeat taps. There is no hold-time (dwell) setting.
Forgiving correction. A wrong letter should be a one-tap fix, silently — not a spoken error, and not a reason to start the sentence over.
How TBoard approaches it
TBoard is a typing-first AAC app for iPad and Android tablets, built around exactly these settings. It works like a keyboard that talks: the person types, sees the words build in the text bar, edits them, and the board speaks when they're ready. Nothing is pre-scripted — whatever a person can spell, they can say. The touch settings (target size, tap guard, tap timing, correction) are all adjustable, and you can also build fully custom boards from photos, icons, or text, from a two-key board up to a full keyboard.
TBoard was built by the brother of a nonspeaking adult with severe speech apraxia, after years of watching standard tablets fail him. It is independent and method-neutral: it isn't affiliated with any named communication methodology, and it makes no treatment claims — it is a tool, and the person using it does the communicating.
Try it with your own settings
Everything is unlocked for a 7-day trial. After that, one purchase — $49.99, once — keeps all of it. Nothing renews. The trial is the whole app, so you can test whether the touch settings fit before deciding anything.
