The operator may return to the main menu interface if the operator clicks the main menu key 402. Furthermore, control of the inter-magnet camera can also be achieved by defining gesture operations of the operator in the image display window 401 described above. For example, a single finger gesture operation that clicks on a location in image display window 401 may represent controlling the inter-magnet camera to focus on the portion of the object displayed at that location; the gesture operation of sliding two fingers from the center of the image display window 401 to opposite directions can represent controlling the camera in the magnet to increase the magnification; the gesture operation of sliding two fingers from the edge position to the center position of the image display window 401 may represent controlling the camera in the magnet to reduce the magnification; a single finger sliding in a certain direction in the image display window 401 may represent controlling the shooting angle of the camera in between the magnets.
In addition, the user interface may further include a switch button for switching between images captured by different cameras, for example, an arrow located on the left/right side or the top/bottom side of the image display window 401. After the operator clicks the switching key, images shot by different cameras in the magnet room can be sequentially checked according to a preset sequence. In an embodiment of the present application, the operation of the operator clicking the switching key may be regarded as an operation of inputting camera activation/hibernation instruction information, thereby controlling the activation or hibernation state of the plurality of cameras within the magnet room.

The display section 501 and the input control section 502 may be connected by wire or wirelessly. Further, the angle of the display section 501 with respect to the input control section 502 is adjustable when the display section 501 and the input control section 502 are coupled together. By such a design, the use of the operating unit 100 can be made more flexible and convenient.
