Abstract:
1. A communication terminal having a function of designating a position on a screen of an external display device, comprising: a touch panel, which receives a contact operation and outputs position information representing the contact position, and which includes a first operation area configured to receive a position designating operation and a second operation area configured to receive a response operation to respond to an event occurring according to an execution of another function; a detector, which detects occurrence of the event and outputs a notification signal; a controller, which determines whether the position information represents the first operation area or the second operation area; a transmitter, which receives the position information and transmits the received position information to the external display device; and a processor, which performs a process corresponding to the notification signal, wherein, in a case where the position information represents the first operation area, the controller outputs the received position information to the transmitting unit, wherein, in a case where the position information represents the second operation area and the notification signal is received, the controller controls to perform a process corresponding to the notification signal and does not output the received position information to the transmitter, wherein in the case where the notification signal is received, the controller outputs a message representing the occurrence of the event, and wherein, the touch panel displays the message in the first operation area.
