Claims

physical quantity is between the minimum threshold and the maximum threshold of the first focal length.

6. Control method according to any one of claims 1 to 5 wherein the projection device (120) comprises a plurality of orientable projectors and an orientable mirror (132), the projection device being able to: • Receive (S30) the command, and • Select (S40) a projector (131) from the plurality of orientable projectors, an orientation of the projector (131) and an orientation of the orientable mirror (132), so as to project, onto the windshield (140), the graphic element, at the first focal distance.

7. Control method according to any one of claims 1 to 5 wherein the projection device (120) comprises a plurality of orientable mirrors and an orientable projector (121'), the projection device being capable of: • Receiving the command (S30), and • Selecting (S40) a mirror (124') from the plurality of orientable mirrors, an orientation of the orientable projector (121') and an orientation of the mirror (124'), so as to project, onto the windshield (140), the graphic element, at the first focal distance.

8. Computer program comprising instructions, executable by a microprocessor or a microcontroller, for implementing the method according to any one of claims 1 to 7, when executed by the microprocessor or the microcontroller.

9. Electronic device (110) configured to implement the steps of the method according to any one of claims 1 to 7.

10. Motor vehicle (100) comprising the electronic device (110) according to the preceding claim. [Fig. 4] [Fig. 5]
