Oculography method, oculography device, pair of ar or vr smart glasses having the oculography device, and control unit

An oculography device for performing an oculography method, comprising:

• at least one laser feedback interferometry (LFI) sensor array which includes multiple LFI sensors each configured to track at least one eye movement of an eye of a smart glasses user, at least a majority of all of the LFI sensors of the LFI sensor array have unique emission angles and/or unique emission directions;
• wherein the oculography device is configured to perform:
• in at least one oculography step, tracking the at least one eye movement of the eye of a smart-glasses user, by a subset of the LFI sensors of the LFI sensor array which is associated with the eye;
• and
• in at least one selection step which precedes the oculography step in time, making a selection of at least one LFI sensor provided for performing the oculography step, which follows in time, based on a parameter comparison of test measurements of multiple LFI sensors of the LFI sensor array, the selected at least one LFI sensor forming the subset.
