Wearers ​

Wearers are the people wearing Neon. In a typical study, each subject would be a wearer. Every recording you make is assigned to a wearer to help you organize your recordings. You can create new wearers on the fly in the Neon Companion app or in advance using Pupil Cloud. It is also possible to change the assigned wearer in a recording post hoc in Pupil Cloud. Simply select Change Wearer from the context menu of a recording!

Every wearer is assigned a unique ID, such that you can edit the name and profile picture at any time without mixing up your recordings.

Wearer profiles also allow you to save physiological parameters of a subject in order to improve the quality of the eye tracking data. The inter eye distance (IED) for example can be entered to improve the accuracy of pupil diameter estimates. This page overviews how to measure IED.

Gaze estimates for some subjects with rare physiologies can be affected by a systematic offset. In those cases you can define an offset correction in the wearer profile to compensate this effect. Learn more about this in the Offset Correction guide.
