While the automatic tools for gaze mapping in Pupil Cloud work great a lot of the time, they are not applicable in some scenarios:
  • The marker Mapper can not be used if placing markers in the environment is not tolerable.
  • The Reference Image Mapper can not be used in some environments that have very few visual features.
An interface for creating a manual gaze mapping would be helpful in such cases. It would be labor-intensive to map manually, but it enables gaze mapping in scenarios that would otherwise not be possible.
