Method for using a display in a motor vehicle

Abstract

A method for using a display in a motor vehicle, comprising the following steps: - using the display in the motor vehicle, wherein the display is transparent to light; - detecting objects and / or persons outside the motor vehicle; and - highlighting the detected objects and / or persons by means of the display;wherein a driver's gaze direction is detected, wherein objects and / or persons are highlighted particularly conspicuously when they are recognized as important and the driver's gaze is not directed towards them, wherein the highlighting is dependent on the gaze direction, wherein there are gradations of different highlighting depending on the gaze direction and the position of the objects and / or persons, wherein two gaze direction modules (4) of the motor vehicle detect the driver's gaze direction, wherein the gaze direction modules (4) each comprise a camera which is used in detecting the gaze direction, and wherein the gaze direction modules (4) are arranged at lower corner areas of a windshield (1) of the motor vehicle.

Description

The present invention relates to a method for using a display in a motor vehicle according to claim 1.The use of transparent displays in motor vehicles is known from the prior art. For example, parts of the front screen can be used as a display and information useful for the driver can be displayed. DE 20 2014 005 329 U1 discloses using smart glasses as a display, which displays information of an infotainment system of the motor vehicle. In addition, the infotainment system can be controlled by means of the spectacles.DE 10 2018 216 643 A1, DE 10 2016 214 046 A1, DE 10 2015 006 612 A and DE 10 2010 001 684 A1 describe further displays in motor vehicles.In contrast, the present invention is based on the object of increasing the safety in traffic. This object is achieved by a method according to claim 1 and by a system according to claim 5. Embodiments of the invention are set forth in the dependent claims.The method according to claim 1 uses a transparent display in the motor vehicle. In this context, the term "transparent" in the context of this description is understood in particular to mean that the display is transmissive for more than 50%, preferably more than 90%, of the light striking the display. Within the scope of this description, light is understood to mean, in particular, electromagnetic radiation in the spectrum visible to a human eye.Objects and / or persons outside the motor vehicle are detected. An object can be, for example, another vehicle or a traffic sign. This can be done, for example, using one or more cameras. The detected objects and / or persons are highlighted by the display. Within the scope of this description, this is understood in particular to mean that the attention of a driver is directed to these objects and / or persons. For example, the objects and / or persons can be marked. The marking can be visually conspicuous in order to draw the attention of the driver to these objects and / or persons.By alerting the objects and / or persons, safety is enhanced as the risk of the driver overloating one of the objects and / or one of the persons decreases. In particular in the case of poor visibility conditions, the method according to the invention therefore offers a visual advantage.According to one embodiment of the invention, the display can be part of spectacles which the driver wears on his head. In this case, it can be augmented reality glasses, for example.According to one embodiment of the invention, the method can be carried out during a journey using the motor vehicle.According to one specific embodiment of the present invention, the display may be situated in the field of vision of the driver of the motor vehicle between the driver and a roadway on which the motor vehicle is driving. Within the scope of this description, the viewing area is understood to mean in particular the area into which the driver is looking. The driver usually directs his gaze on the roadway in front of the motor vehicle, so that, for example, the front windshield is arranged in the field of vision between the driver and the roadway.According to the invention, the viewing direction of the driver is recognized. The emphasis is performed depending on the viewing direction. For example, objects and / or persons cannot be highlighted if the viewing direction of the driver is already directed at the respective object or the respective person. The emphasis is made particularly conspicuous if the driver does not pucker in the direction of the respective object and / or the respective person. There are gradations of different highlights depending on the viewing direction and the position of the objects and / or the persons. In this way, the attention of the driver can be drawn to particularly relevant objects and / or persons.According to one embodiment of the invention, the viewing direction can be recognized using at least one camera. The camera can be arranged, for example, on the eyeglasses or in the motor vehicle.The system of claim 5 comprises a motor vehicle and a display. The system is configured to perform a method according to an embodiment of the invention.Further features and advantages of the present invention will become apparent from the following description of a preferred embodiment with reference to the accompanying drawing. The same reference numerals are used for identical or similar components and for components having identical or similar functions. This shows FIG. 1 shows a schematic view of an interior of a motor vehicle according to one embodiment of the invention.The motor vehicle comprises a front window 1, a driver's seat 2, a passenger seat 3, two viewing direction modules 4 and a communication module 5. Augmented reality glasses may also be referred to as AR glasses. The driver looks through the AR eyeglasses and the front windshield 1 at a roadway in front of the motor vehicle on which the motor vehicle is driving. The viewing direction modules 4 recognize the viewing direction of the driver. The viewing direction modules 4 can each comprise, for example, a camera which is used when recognizing the viewing direction. The viewing direction modules 4 are arranged at lower corner regions of the front pane 1.Objects and / or persons are detected via a camera, which the driver could see when looking through the front screen 1. Some or all of the objects and / or persons are highlighted by the AR eyeglasses. How many objects and / or persons are highlighted may depend on the viewing direction of the driver, for example. For example, objects and / or persons can be highlighted particularly strikingly if they are recognized as important and the viewing direction of the driver is not directed at them. If the viewing direction is directed in the direction of some persons and / or objects, under certain circumstances it is also possible to dispense with highlighting these persons and / or objects.When carrying out the method, electronic data are exchanged between the motor vehicle and the AR spectacles via the communication module 5. For example, the viewing direction modules 4 can send information about the viewing direction of the driver to the AR spectacles, which can then adapt the highlights of the objects and / or of the persons.
