12. The terminal according to claim 1 , wherein a user input is an input of the user's voice for instructing a movement of the first display window.

13. The terminal according to claim 1 , wherein a user input is an input operation performed by an external input device, and

wherein the circuitry is further configured to obtain the input operation through wireless communication with the external input device.

14. The terminal according to claim 1 , wherein the display screen includes a first display region that displays the first display window and a second display region that displays an operation tray including icons, and

wherein, when the first display window is displayed in a region at an end of the first display region, the circuitry is further configured to change the state of the first display window to the first display state in response to a user input for moving the first display window outside of the first display region in accordance with a direction of the movement of the first display window.

15. A method implemented by a terminal comprising a display screen and circuitry, the method comprising:

controlling display of a first display window on the display screen, the first display window having a movement element;

obtaining a user input through the movement element for moving the first display window on the display screen;
