Method for detecting the gaze direction of a wearer of data glasses and a computing unit

Abstract

The invention relates to a method for detecting the gaze direction of a wearer of smart glasses (10), in particular an AR headset or a VR headset, which comprises a laser feedback interferometry (LFI) multipoint sensor (12), wherein the LFI multipoint sensor (12) generates a plurality of LFI measurement points (14, 16) in an area of ​​the smart glasses (10) intended for positioning one eye (18) of the wearer, and wherein the LFI multipoint sensor (12) detects back-reflected signals (20) from the LFI measurement points (14, 16) reflected by the wearer's eye (18). It is proposed that a characteristic distance signal pattern (22), which differs for different gaze directions of the wearer's eye (18), be read out from the back-reflected signals (20) and evaluated to determine the gaze direction.
