Pupil v2.3 is a compatibility release for Pupil Invisible, adding support for a simple gaze confidence measure.


Pupil Invisible Gaze Confidence - #1984

With its latest 0.8.23 release, Pupil Invisible can detect if the glasses are being worn. If they are not worn, gaze output will be hidden.

We now use this information as a simple binary gaze confidence when loading Pupil Invisible recordings in Pupil Player. If the glasses are detected as being worn, the gaze confidence will be 1.0, otherwise 0.0.

Smaller Improvements

  • Added better log message for pupil mobile network issues - #1994
  • Renamed ‚Äúcamera calibration‚ÄĚ to ‚Äúcamera intrinsics‚ÄĚ to avoid confusion with gaze calibration - #1992
