EYEUM lets people living with ALS speak words using only eye movements — no touch, no controllers, no expensive hardware.
EYEUM pairs camera-based eye tracking with a board where the words you use most are always the fastest to reach.
Uses the front camera of a standard phone or tablet, and only left and right eye movements. No headset, no infrared rig, no calibration lab required.
The words and phrases you use most sit within the fewest glances, so everyday communication comes out faster.
Each completed word is read aloud with built-in text-to-speech, so caregivers hear it instantly.
Large targets, high-contrast text, and quick caregiver phrases designed with accessibility first — not as an afterthought.
Every word on the board carries a short binary code — 0 for a glance left, 1 for a glance right. The patient finds the word they want and reads its code.
A glance to the left adds a 0, a glance to the right adds a 1. Each digit appears on screen as it is entered, so the code can be followed as it forms.
Gazing at the center for about two seconds completes the code. If it matches a word in the book, the app speaks it aloud through the device speaker.

EYEUM is a research project, and it improves only when people tell us how it went. Please use it for a week or two with the person you're supporting, then come back to this site and leave your notes. What didn't work matters most.
The feedback form lives at the bottom of this page, under "Already tried EYEUM?" — or use the Feedback link in the top menu whenever you return.
Choose your platform below, then pick the manual in your language.
Start with the quick guide; the full manual covers setup and troubleshooting in detail.
Reminder: keep a reliable backup way to call for help. EYEUM should not be your only means of communication in an emergency.
We're building this with the ALS community, not just for it. If you'd like to share how it went — what worked, what didn't, what would help — we'd be grateful. It's completely optional.
