Abstract A method for displaying information for a user of a vehicle by means of a projection system, which has a projection unit, a control device, a first projection field, and at least one second projection field, wherein the information is transferred from the control device to the projection unit, and wherein the projection system is switched over from a first beam path, in the case of which light beams produced by the projection unit are directed onto the first projection field, to a second beam path, in the case of which light beams produced by the projection unit are directed onto the at least one second projection field, in accordance with the current position of a seat of the user, the light beams produced by the projection unit being deflected to a field of view of the user by the at least one second projection field. ## Claims ### Claim 1 A method for displaying information for a user of a vehicle by a projection system, comprising: arranging a first projection field on a windshield of the vehicle, arranging at least one second projection field on a roof liner of the vehicle, separate from the windshield, transferring information from a control device of the vehicle to a projection unit, and switching the projection system between a first beam path and a second beam path based on an orientation of the user of the vehicle, wherein the first beam path directs light beams produced by the projection unit to the first projection field, the projection system switching to the first beam path when a seat of the user is in a driving position whereby the user is oriented substantially vertically with respect to a chassis of the vehicle, and wherein the second beam path directs the light beams produced by the projection unit to the at least one second projection field, the projection system switching to the second beam path when the seat of the user is in a comfort position whereby the user is oriented substantially horizontally with respect to the chassis of the vehicle. ### Claim 2 (depends on 1) The method according to claim 1, wherein switching the projection system between the first and second beam paths comprises: adjusting, as a function of a current position of the seat, an orientation of the projection unit with respect to the first or the at least one second projection fields so that the light beams produced by the projection unit meet a field of view of the user. ### Claim 3 (depends on 1) The method according to claim 1, further comprising: adjusting, as a function of a current position of the seat, an orientation of the at least one second projection field so that the light beams produced by the projection unit meet a field of view of the user. ### Claim 4 (depends on 1) The method according to claim 1, wherein, when the user activates a calibration mode, an orientation of the projection unit and of the at least one second projection field with respect to the user are changed until the user ends the calibration mode. ### Claim 5 (depends on 1) The method according to claim 1, wherein the projection system is switched from the first beam path to the second beam path when an autonomous driving mode of the vehicle has been activated. ### Claim 6 A projection system for displaying information in a vehicle, comprising: a projection unit, a control device, a first projection field arranged on a windshield of the vehicle, and at least one second projection field arranged on a roof liner of the vehicle, separate from the windshield, wherein the projection system is configured to be switched between a first beam path and a second beam path based on an orientation of the user of the vehicle, wherein the first beam path directs light beams produced by the projection unit to the first projection field, the projection system switching to the first beam path when a seat of the user is in a driving position whereby the user is oriented substantially vertically with respect to a chassis of the vehicle, and wherein the second beam path directs the light beams produced by the projection unit to the at least one second projection field, the projection system switching to the second beam path when the seat of the user is in a comfort position whereby the user is oriented substantially horizontally with respect to the chassis of the vehicle. ### Claim 7 (depends on 6) The projection system according to claim 6, wherein the projection system switches from the first beam path to the second beam path when an autonomous driving mode of the vehicle is activated. ### Claim 8 (depends on 6) The projection system according to claim 6, wherein an orientation of the projection unit is adjustable, as a function of a current position of the seat, with respect to the first or the at least one second projection fields so that the light beams produced by the projection unit meet a field of view of the user. ### Claim 9 (depends on 6) The projection system according to claim 6, wherein an orientation of the at least one second projection field is adjustable, as a function of a current position of the seat, so that the light beams produced by the projection unit meet a field of view of the user.
