In Pupil v2.4, we are adding support for eye camera intrinsics. These are used to improve 3d eyeball model positioning. Additionally, we have fixed a long-standing issue that caused application windows not to appear on startup when using Windows OS.
Better 3D Eyeball Position - #1995
We now use the focal length of the eye cameras to improve the estimate of the 3D eyeball position. Previously, the 3d eye model assumed a fixed camera focal length. This will most likely not have any noticeable effect for most use-cases, as it does not influence the gaze estimation. We assume default focal lengths for the different types of eye cameras shipped with Pupil Labs’s hardware.
Caveat: 200Hz Vive Add-on Recordings
Pupil Core software now saves the eye camera intrinsics to the recording folder. On opening recordings made with previous versions in Pupil Player, we patch up the recording by inserting the appropriate eye camera intrinsics.
It is important to note that the 200Hz Pupil Core and 200Hz Vive Add-on use eye cameras with different focal lengths. Unfortunately, it is not possible for Pupil Player to differentiate between existing eye videos made by these cameras. As a result, Pupil Player will use 200Hz Pupil Core eye camera intrinsics for existing 200hz Vive Add-on eye videos.
Recordings made with Pupil Capture v2.4 and higher will not require any action in this regard.

pupil-detectors - #1995
We have updated pupil-detectors to v1.1.1, please update with
pip install -U pupil-detectors
packaging - #1993
We now require
packaging>=20.0, please update with
pip install -U packaging
Internal Version Parsing - #1993
We have switched to a more general version-parsing method by using
packaging.version.parse to parse all internally used version strings (from Pupil and external dependencies).
Black Formatter 20.8 - #2003
We have upgraded our black formatter to version 20.8, which introduces a few changes to previous versions and reformats parts of the code which were fine previously. Please make sure to also upgrade black with
pip install -U black
