GLINTOS MINI-APP · SYSTEM
See what the tracker sees.
One calibration for the whole OS.
Eye Lab shows your eye as the Maverick AI Pro eye tracker sees it, and runs the gaze calibration every GlintOS app shares. No account, API key or internet.
What it is.
Eye Lab is the eye-tracking workbench of GlintOS for Everysight Maverick AI Pro, the model with an eye tracker. It draws your eye as the tracker reports it and shows the signals GlintOS reacts to: blinks, double blinks, looking left or right, fixation, and whether your eyes are visible and open.
It also runs the one gaze calibration the whole OS uses, 18 dots in about 25 seconds, plus an accuracy test in display pixels. The calibration powers the experimental Gaze focus setting, off by default: look at something to focus it, then tap to select it. Gaze is experimental because the current Everysight SDK does not yet turn gaze into a point on the display.
What you get.
Blink and gaze signals
Blinks, blinks per minute and double blinks, LEFT, CENTER or RIGHT, fixation time, and whether your eyes are visible and open.
One calibration, OS-wide
Two rounds over nine targets, saved on your phone and used by Gaze focus everywhere in GlintOS.
Nothing pulls your eye
During a run the display shows only a dot and a ring closing on it, with no text, counter or button.
Clear quality figures
The expected error in pixels, a straight or curved fit, and how many points were used. GlintOS drops outliers itself.
A test that learns nothing
Six random dots report the mean and worst error. A stopped or failed run keeps your previous calibration.
On your glasses.
Menu
Live eye, Signals, Calibrate gaze, Accuracy test, Auto calibrate (simulator only) and Forget calibration, each with its status. Restart tracker appears when the tracker fails.
Live eye
The eye drawing beside its status table, or No eye in view when the tracker finds no eye.
Signals
The direction row, BLINKS, PER MIN and DOUBLE, and fixation, eyes visible and OPEN or CLOSED. Reset zeroes the counters.
Calibrate
Start clears the display to one dot at a time. The result, marked SAVED ON THE PHONE, offers Test and Done, or Retry if the run failed.
Accuracy test
Six dots, then the error in pixels and a table of mean, worst, expected and dots measured. It needs a calibration first.
How you control it.
| Swipe forward | Next row or button. Ignored during a run, so a stray touch cannot spoil it. |
|---|---|
| Swipe back | Previous row or button. During a run, stops it and keeps your previous calibration. |
| Tap | Opens the focused row or presses the focused button, such as Start, Test, Reset or Restart. |
| Long tap | Back by default. If Long tap is set to Assistant, it starts the assistant on normal screens. During a run it always stops the run. |
Gestures come from the temple touchpad on Maverick AI and AI Pro glasses. An optional R08+ smart ring can send the same gestures from your finger.
Home and phone.
No widget of its own. While Eye Lab runs, the Home Summary widget can show its status: the gaze error, Calibrating or Gaze not calibrated.
Eye Lab’s page in the phone companion app shows the tracker’s state, frame rate and last error, the blink and gaze readings, and the calibration status.
Restart tracker and Forget calibration buttons. Forget on the phone clears at once, without asking.
Calibration starts only on the glasses, and the values update only while Eye Lab is open there.
What you need.
- Glasses
- Maverick AI Pro, connected
Eye Lab needs the AI Pro’s eye tracker. On glasses without one it may open but show no eye data or an error.
- Phone
- Android 11 or later
GlintOS runs on the phone and draws on the glasses.
- Account
- Not needed
There is nothing to sign in to.
- API key
- Not needed
Eye Lab uses no third-party service.
- Internet
- Not needed
Eye data is processed on the glasses and the phone.
- Permissions
- Eye tracking; Gaze point optional
GlintOS switches, on by default, under Apps > Eye Lab > Access on the phone or Settings > Privacy on the glasses. Without Gaze point, calibration is unavailable.
- Hardware
- R08+ smart ring, optional
Paired with the phone in touch mode, with Ring control and the GlintOS ring control accessibility service on, it sends the same gestures as the temple touchpad.
- Cost
- None
No paid service or subscription.
These rows are about Eye Lab. GlintOS itself also needs internet on the phone the first time it connects to your glasses and about once a month after that, when the glasses’ security certificate is renewed.
Set it up.
- Install GlintOS on an Android 11 or later phone and connect your Maverick AI Pro glasses.
- Open Eye Lab and check that Live eye shows the drawing and a frame rate.
- Pick Calibrate gaze, tap Start and look at each dot until its ring closes.
- Run Accuracy test, and re-check a saved calibration on each new day.
- Optional: turn on Gaze focus under Settings > Input.
Your data.
- Eye Lab uses no internet and stores nothing itself. Eye data streams only while it is open on the glasses.
- GlintOS receives no picture of your eye, only geometry, which Eye Lab draws.
- The calibration stays in GlintOS’s private storage on the phone, excluded from cloud backup. Forget calibration deletes it; Clear data does not.
Good to know.
- So far Eye Lab has been tested only with the PC glasses simulator, whose synthetic eye is ideal.
- One calibration is kept, so another wearer must recalibrate. A wink cannot be told from a blink, and Auto calibrate works only with the simulator.
- With Gaze focus on, the tracker runs whenever the glasses are ready, which costs battery.
Questions.
Does Eye Lab work on Maverick AI glasses without eye tracking?
It is made for Maverick AI Pro, the model with an eye tracker. GlintOS cannot detect a missing tracker, so on other glasses it may open but show no eye data or an error. This is not verified.
Do I need an account, API key or internet for Eye Lab?
No. Eye Lab contacts no service and needs no sign-in or key. Eye data is processed on the glasses and your phone.
How accurate is Eye Lab’s gaze calibration?
Run Accuracy test to see the mean and worst error for your own eyes. The only documented figure, about 1 to 2 px, comes from the PC simulator. Real-glasses figures are not yet known.
Is Eye Lab made by Everysight?
No. Eye Lab is part of GlintOS, an independent project not affiliated with or endorsed by Everysight. GlintOS is in development, with the free public APK planned for December 2026, and real-glasses validation is pending.
