We are pleased to announce the beta release of hmd-eyes v1.0!!

hmd-eyes v1.0 is a going to be a complete overhaul of the current hmd-eyes plugin, with a cleaner and more flexible architecture. We are dropping support for the 2d approach and focus entirely on 3d gaze tracking. Starting with a new gaze demo scene and more robust gaze visualization.

Please refer to the release/beta branch for checking the readme and documentation.

We also created a dedicated channel #hmd-eyes-alpha on our discord server to gather your feedback and post about updates.

Dependencies

  • Unity 2018.3+
  • ProjectSettings/Player/Configuration/Scripting Runtime Verion set to .NET 4.x Equivalent.
  • Due to an issue with MessagePack, the default project setting for ProjectSettings/Player/Configuration/API Compatibility Level is not supported and needs to be set to .NET 4.x
