Method for operating a display apparatus in a motor vehicle , comprising the steps of: - detecting, by means of a sensor system of the motor vehicle , environment data which relate to at least one environment region which belongs to the environment around the motor vehicle and which lies within a field of view of a user - providing at least one item of information to be output to the user by means of an information source , - making visible to the user an at least partially superimposed representation of an information representation which reproduces the item of information, and of the environment region by means of the display apparatus , wherein the type of information representation and/or the position at which and/or the orientation in which the information representation is made visible depends on the environment data, wherein a three-dimensional environment model describing the environment region is ascertained from the environment data, wherein, depending on the item of information and the environment model, a two-dimensional information object is generated and positioned and/or orientated in a coordinate system prescribed with respect to the environment model, after which the information representation is generated by a projection of the information object, characterised in that distances or relative speeds of other road users, specifically motor vehicles, are represented as information, wherein a surface of an object , specifically the respective motor vehicle, is selected in the environment model, wherein the two-dimensional information object is arranged on this surface by providing the two-dimensional information object as a pixel or vector graphic and applying it as a texture to the corresponding surface. - detecting, by means of a sensor system of the motor vehicle , environment data which relate to at least one environment region which belongs to the environment around the motor vehicle and which lies within a field of view of a user - providing at least one item of information to be output to the user by means of an information source , - making visible to the user an at least partially superimposed representation of an information representation which reproduces the item of information, and of the environment region by means of the display apparatus , wherein the type of information representation and/or the position at which and/or the orientation in which the information representation is made visible depends on the environment data, wherein a three-dimensional environment model describing the environment region is ascertained from the environment data, wherein, depending on the item of information and the environment model, a two-dimensional information object is generated and positioned and/or orientated in a coordinate system prescribed with respect to the environment model, after which the information representation is generated by a projection of the information object, characterised in that distances or relative speeds of other road users, specifically motor vehicles, are represented as information, wherein a surface of an object , specifically the respective motor vehicle, is selected in the environment model, wherein the two-dimensional information object is arranged on this surface by providing the two-dimensional information object as a pixel or vector graphic and applying it as a texture to the corresponding surface. <EOS>
