Abstract: A control system for displaying a corresponding control interfaces on a control device based on different external devices comprises storage with a plurality of control interfaces corresponding to different external devices in one-to-one relationship, a searching module, a communicating module, a displaying module, and a selecting module. The searching module searches external devices matched with the control device in a predetermined range around the control device. The communicating module obtains feature information from the matched external devices in response to the communicating signal. The displaying module extracts and displays the obtained feature information. The selecting module selects one of matched external devices as an object device based on the displayed feature information. The display module further extracts and displays the control interface corresponding to the object device for controlling the object device.
