Abstract: A method for calibrating a tracking system that determines, from the outside, a position of a head-mounted display, includes arranging a display unit in the capture range of a camera communicatively connected to the tracking system. The method includes actuating the display unit, using the tracking system, to continuously display a current system time. The method includes capturing a camera image that includes the system time. The method includes evaluating the camera image to obtain an image capture time corresponding to the system time. The method includes providing a latency based on the image capture time.

Abstract: A method for determining a pose of a pair of smart glasses in an interior of a mobile machine includes capturing a camera image of an interior of the mobile machine and determining a relevant glasses type for the pair of smart glasses imaged by evaluating a data-based glasses-type recognition model using the captured camera image. The glasses-type recognition model is trained to assign a camera image to a relevant glasses type of one or more pairs of smart glasses. One of a plurality of data-based pose recognition models is selected depending on the recognized glasses type. The pose recognition models are each trained for one glasses type to determine a glasses pose of the corresponding pair of smart glasses according to the camera image. The glasses pose of the pair of smart glasses of the corresponding glasses type is determined via the selected pose recognition model.

Abstract: A seat position control device for automatically adjusting the seat position of at least one occupant in a vehicle includes a sensor device configured to detect an action of the occupant for starting a media content on smart glasses and subsequently a seat position intention of the at least one occupant, a control device configured to process the data of the sensor device and to adjust the seat position of the at least one occupant to a predefined seat position based on the processed data. Also disclosed is a seat position control method and a vehicle with the seat position control device.

Abstract: A method for operating a display system including smartglasses in a vehicle that has a glasses-external central processing unit is disclosed.

Abstract: A method for operating a display system for smart glasses in a vehicle includes determining at least one environment region that is intended to be blurred at a position relative to an environment coordinate system or a vehicle coordinate system. Object information is generated for transmission to the smart glasses. The object information defines a display object as a blur object of the determined at least one environment region and defines the position of the at least one blurred environment region in order to superimpose the display object on the at least one environment region to be blurred within the perception region of the wearer of the smart glasses.

Abstract: A method for operating a display system for smartglasses in a motor vehicle includes ascertaining a spatial image representation of a rear vehicle environment with the aid of an environment capture device includes a camera system for providing a camera image representation and a 3D capture device for providing a distance profile; communicating at least one portion of the spatial image representation of the rear vehicle environment as object information to the smartglasses; and performing contact-analog presentation of display images on a display surface of the smartglasses in a presentation region at a vehicle-fixed position, which region corresponds to a vehicle mirror position, wherein the display images are created stereoscopically depending on the spatial image representation of the rear vehicle environment with the aid of a graphics engine implemented in the smartglasses in order to enable a spatial presentation of environment objects of the rear vehicle environment.

Abstract: A display system is operated with an assistance system tied to the vehicle and data glasses in a vehicle. It is monitored whether a presentation surface has been brought from a stowed position into a position of use in which the presentation surface faces the data glasses. The presentation surface is a dark or black unstructured surface. If it is recognized that the presentation surface has been brought into the position of use, start information from the assistance system is transmitted to the data glasses. Media information in the data glasses is automatically started and displayed depending on the start information.

Abstract: A method assigns an absolute glasses pose indication acquired outside the glasses to one of multiple data glasses in a vehicle.

Abstract: A method for operating smart glasses for the augmented presentation of information objects on a display surface on the basis of a smart glasses pose in a vehicle interior is provided. The smart glasses pose is ascertained by inside-out tracking on at least one marker provided fixedly in a vehicle interior or at least one object provided in the vehicle interior. The at least one marker or the at least one object can be located by a computer-assisted pattern recognition method which is applied to a camera image of a smart glasses camera so that the smart glasses pose relative to the vehicle interior can be determined on the basis of a position, size and/or orientation of the at least one marker or of the at least one object. Only the camera image outside of a masking region is taken into account for the pattern recognition method.
