Patent ID: 10956112

Abstract:
A method for a touchscreen mobile device (35) to control a remote display device (31), where the touchscreen comprises a touch sensitive input layer and an internal display for displaying an image of the main screen of the mobile device (35) showing one or more applications that the mobile device (35) is executing. When the mobile device (35) is connected to the display device (31), the mobile device (35) enters a display mode in which the mobile device (35) transmits the image to the display device (31) for display on the display device (31) and does not displace the image on the internal display, but maintains the touch sensitive input layer operational to enable the mobile device (35) to be used as an input/output device with which a user can interact using the touch sensitive input layer, such as a keyboard (34), game controller or other input device, such as a trackpad to sense movement of one or more fingers of a user across the touch sensitive input layer for controlling a cursor.
