Abstract: A computing unit for ascertaining the viewing vector of a user of smart glasses. The computing unit receives first image data recorded using a first sensor unit at a first time interval and generates a respective image of an eye of the user based on the recorded first image data. The computing unit ascertains first rotational speed data of the user's eye which is recorded using a second sensor unit at a second time interval shorter than the first time interval. The computing unit ascertains a first viewing vector information of the user of the smart glasses based on the generated image of the eye and ascertains at least one second viewing vector information of the eye based on the received first rotational speed data of the eye. The computing unit ascertains the viewing vector of the eye based on the ascertained first and/or second viewing vector information.

Abstract: A method for operating a MEMS system having a projection unit for providing an image via a light beam, and a deflecting unit for the two-dimensional deflection of the at least one light beam. The method includes: driving the deflecting unit via a reference signal, so that the deflecting unit periodically deflects a light beam at least two-dimensionally, measuring a controlled variable of the deflecting unit that corresponds to an actual position of the deflected light beam, ascertaining a current deviation of the controlled variable from a target variable that corresponds to a target position of the light beam, calculating a compensating variable based on the ascertained deviation, controlling the deflecting unit and/or controlling the projection unit based on the calculated compensating variable for reducing the deviation of the light beam from the target position. The compensating variable is additionally calculated based on an earlier deviation in an earlier period.

Abstract: A method for determining a direction of gaze of an eye for data glasses. The method includes: reading distance values and speed values, which represent a distance between laser sensors for emitting laser beams and surface intersection points of the laser beams on the eye and also surface speeds at the surface intersection points; classifying the distance values and the speed values in order to obtain classification values which indicate the parts of the eye associated with the surface intersection points; estimating position values which represent positions of the laser sensors using the distance values, the speed values, and the classification values; and ascertaining a gaze direction value which represents the gaze direction using the position values, the distance values, and the speed values.

Abstract: A method for determining an eye position. The method includes: receiving laser feedback interferometry measurement values of a laser feedback interferometry measurement of an eye by means of at least one laser interferometry unit; determining a velocity component of the component of the eye relative to the laser feedback interferometry unit based on the laser feedback interferometry measurement values; determining a rotational velocity of the eye about an axis of rotation based on the rotational velocity about the axis of rotation by integrating the rotational velocity over a predetermined time segment; and providing the eye position.

Abstract: The invention relates to a method for operating an electric machine (1), in particular of a motor vehicle, that has a stator (4) and a rotor (2), wherein the stator (4) has a stator winding (5) having at least three phases (U, V, W), and wherein the rotor is arranged/arrangeable on a rotor shaft (3), wherein a time-invariant differential equation modelling the machine (1) is taken as a basis for ascertaining a desired current value (Idesired,fl) for the stator winding (5) for producing a required torque and/or a required rotation speed, wherein the desired current value (Idesired,fl) is compared with an actual current value (Iactual,fl) of the stator winding (5), which actual current value corresponds to electric phase currents (IU, IV, IW) flowing through the phases (U, V, W), and wherein the comparison is taken as a basis for passing current through the phases (U, V, W) such that a difference from the actual current value (Iactual,fl) to the desired current value (Idesired,fl) is reduced.
