Scope
What has been tested, what has not, and what Glint does not claim.
Glint is at version 0.1. This page says plainly what has been checked, so you can decide whether it fits what you need.
What has and has not been tested
| Area | Status |
|---|---|
| Board, scanner, settings | Tested. Unit tests, plus an end-to-end test that drives the packaged Linux app on every CI run. |
| Eyebrow and exhale detectors | Tested on one recording. One person, one session, three examples of each gesture. Results are on Why eyebrows?. |
| SDK signals on a live camera | Tested in an early prototype, which is where the recording came from. |
| The finished app on a real camera | Not yet run. Its live path has run only against a simulated camera, up to an authentication failure. |
| Use by disabled people | Not tested. Nobody who needs switch access has tried Glint. |
| Linux build | Tested in replay mode. CI smoke-tests the unpacked build; the AppImage itself has been run locally only. |
| Windows installer | Builds in CI. Never installed or run on a Windows machine. |
| macOS | No build. The SDK supports Apple Silicon, but Glint has no macOS packaging. |
| Calibration | Not built. Thresholds are the same for everyone. |
| Word prediction | Not built. |
What Glint does not claim
Glint is not a medical device. It makes no diagnosis and no health judgement. Pulse is shown only so you can see that you are being read, and no decision uses it.
Do not rely on Glint as your only way to call for help. A missed gesture is expected behaviour: on the test recording, the eyebrow detector caught two of three raises.
Known limits
- Light matters. The camera needs light on your face. In dim light, the SDK pauses the app with a hint.
- Blinks do not work as a gesture in the conditions we tested: thick-framed glasses in a dim room.
- The free SDK tier is small. At the time of writing, 100 credits, where 1 credit is 30 seconds of measurement. That is 50 minutes.
- Linux speech needs an extra package. See Installation.
