Hi ABob53, hi marc, hi Papr, I measurement focus point distances via 3D model to quantify the "work load" of the eye. Near work is considered as higher effort for...

@ABob53 Hi ABob53, with little tricks you can still gain reasonable good focus distance data. It requires filtering of invalid and inconsistent data and adjustment of the pupil distance to...

Hi ABob53, that's right I apply a correction. Fist of all I experienced that the relative depth data is in most of the data sets. Due to the small angels...

Hi @ABob53 The longitudinal movement of the eye(z-direction) associated with blink is described by https://www.ncbi.nlm.nih.gov/pubmed/8591916 Riggs https://www.ncbi.nlm.nih.gov/pubmed/6481436 Evinger Just to clarify. Changing eye ball radius is maybe one way to...

@jhs0053 sorry for the delay, I was on vacations. Out of the 3D eye model and the Gaze_positions you can calculate the pupil distance. all dimensions are in the world...

hi @962557346, I just do post processing of exported pupil positions. At a given time in my recordings I know the object distance and from there I adjust the PD...
