Reference numeral 804 denotes a pointer moving button displayed on the screen on which the pointer 801 is displayed, in this example, the presenter screen 110.

  The difference from the first embodiment is that when there is an input that the input signal presses the pointer movement button 804 by the input signal input by the user input means 301, the pointer 802 is displayed on the presenter screen 110 as a listener. The screen is moved from the screen 210 for the audience or the screen 210 for the listener to the screen 110 for the presenter.

  In this example, the pointer 801 is moved when there is an input from the presenter that the pointer moving button is pressed. However, a predetermined key operation (Ctrl key + M key) may be performed from the keyboard. . Further, the predetermined key operation may be freely designated by the presenter or may be predetermined.

  In this example, the pointer 801 is moved when the presenter inputs that the pointer moving button is pressed. However, the screen where the pointer 801 exists (the presenter screen 110 in this example) is outside the screen. The pointer 801 may be moved to the middle position of the screen where the pointer 801 does not exist (in this example, the listener screen 210).

  In this example, it is assumed that the pointer 801 is moved when there is an input from the presenter that the pointer moving button is pressed. However, when the pointer 801 is moved onto the child screen 120, the pointer 801 is moved to the child screen 120. And may be moved to a relative position on the listener screen 210. Alternatively, it may be moved to the middle of the listener screen 210.

  In addition to moving the pointer 801 to the child screen 120, the pointer 801 may be moved onto the listener screen 210 when an event such as a click or double click occurs.

  Here, some examples of input signals that serve as a trigger for moving the pointer 801 are given. However, an input for moving the pointer 801 from the presenter screen 110 to the listener screen 210 and the pointer 801 as a listener. The input for moving from the presentation screen 210 to the presenter screen 110 may be different.

  Further, there are two or more inputs for moving the pointer 801 from the presenter screen 110 to the listener screen 210, and an input for moving the pointer 801 from the presenter screen 210 to the presenter screen 110. There may be two or more.

  When the pointer 801 is moved, if the pointer 801 is grasping the application window 803 by drag input, both the application window 803 and the pointer 801 may be moved.

(Embodiment 4)
This presentation support system has the same configuration as that of the first embodiment shown in FIGS.

  The control means 300 holds the current position information of the child screen 120. When the child screen 120 is moved to the audience screen by the user input means 301, the control means 300 does not move the child screen 120. The child screen 120 is returned to the held position before the movement.

  Here, the position before the movement is used, but the control unit 300 calculates the position after the movement from the position before the movement, permits the movement to the boundary of the screen 110 for the presenter, and permits the movement from there. No, the child screen may be moved to a position where the border of the presenter screen 110 collides with the line segment connecting the position before the movement to the position after the movement.

  In this example, the case where there is one presenter screen 110 is taken as an example, but in the case where there are a plurality of presenter screens 110, the sub screen 120 can be moved only within a screen that is not displayed to the audience.
