Abstract

A method for operating smart glasses includes an input unit and/or output unit and a gaze detection arrangement, wherein the gaze detection arrangement detects any eye movement of an eye including the steps of irradiating at least one wavelength-modulated laser beam to the eye, detecting an optical path length of the emitted laser beam based on laser feedback interferometry of the emitted laser radiation with backscattered radiation from the eye, detecting a Doppler shift of the emitted and backscattered radiation based on the laser feedback interferometry, and detecting an eye velocity based on the Doppler shift, and wherein the input unit and/or output unit is operated based on the optical path length and/or the eye velocity.
