Claim Text:
1. A method for projecting a user interface of an application program provided for a screen of a mobile device, the application program running in the mobile device, onto a screen of an infotainment system arranged in a vehicle, determining, in the infotainment system, a first device independent pixel size representing a screen size of the infotainment system; transmitting the first device independent pixel size representing the screen size of the infotainment system via a data interface to the mobile device, determining, in the mobile device, a second device independent pixel size representing a user interface size of the application program running in the mobile device; comparing the first device independent pixel size representing the screen size of the infotainment system with the second device independent pixel size representing the user interface size of the application program running in the mobile device; and determining in the mobile device, based on the comparison, whether and, if so, which image data concerning the user interface are transmitted from the mobile device via the data interface to the infotainment system, wherein image data including a modified user interface are transmitted from the mobile device via the data interface to the infotainment system, if the comparison shows that the first device independent pixel size representing the screen size of the infotainment system is smaller than the second device independent pixel size representing the user interface size of the application program running in the mobile device, and the application program has a modified user interface available for the screen size of the infotainment system, and wherein at least two modified user interfaces are available, each of the at least two modified user interfaces corresponding to a respective layout class stored in an application program in the mobile device.
