    [0035] FIG. 5 is a diagram showing a case where the mobile device 100 switches an application to the background state. When an application is switched to the background state, the application is being executed, but the application is not displayed.

    [0036] FIG. 5 shows an example in which the mobile device 100 displays a desktop screen while displaying real time bus information. When a user does not terminate an application for displaying bus information, real time bus information is switched to the background state, and the application for displaying bus information is continuously executed. When the user executes another application by using the mobile device 100 and does not terminate a previous application, the previous application is continuously executed. Accordingly, the mobile device 100 does not display an execution screen image of the previous application on the touch screen display 110 of the mobile device 100, but transmits an image of a region 50 in an execution screen image of the previous application to the wearable device 200. Therefore, the wearable device 200 may continuously display bus information.
