Abstract

The invention relates to a sensor unit (105) for smart glasses. The sensor unit (105) comprises at least one sensor (605a) for detecting the gaze direction of an eye, wherein the at least one sensor (605a) is configured as a laser feedback interferometry sensor. The sensor unit (105) also comprises a deflection device (605e) with an electroactive polymer material (605g) and electrodes (605i). The deflection device (605e) is mechanically coupled to the at least one sensor (605a) and is configured to move the at least one sensor (605a) in response to an electrical voltage (U) applied to the electroactive polymer material (605g) via the electrodes (605i), in order to deflect light rays emitted by the at least one sensor (605a).
