Screen sharing system, screen sharing method, and storage medium

An information processing apparatus for a system including the information processing apparatus and another information processing apparatus that are connectable to each other via a network, the information processing apparatus comprising:

• a first display;
• a memory storing a program;
• and
• a processor configured to execute the program to perform a process including
• storing, in the memory, a display content that includes multiple pages and is shared with the another information processing apparatus,
• displaying the display content stored in the memory on the first display,
• displaying, on the first display, a first graphical user interface for receiving a right request to obtain a right for performing one or more input operations including at least a page turning operation on the display content,
• displaying, on the first display, a page of the display content that is same as a page displayed on a second display of the another information processing apparatus in response to a page turning operation performed on the another information processing apparatus by a presenter having the right,
• displaying, on the first display, a second graphical user interface for receiving requests to switch a screen-sharing mode between a shared mode and a non-shared mode,
• when the screen-sharing mode is switched from the shared mode to the non-shared mode according to a request received by the second graphical user interface, enabling the information processing apparatus to independently receive the page turning operation on the display content, and
• when the screen-sharing mode is switched from the non-shared mode to the shared mode according to a request received by the second graphical user interface while the first display is displaying a page of the display content different from the page being displayed on the second display of the another information processing apparatus operated by the presenter having the right, causing the first display to display a page of the display content that is the same as the page being displayed on the second display, according to operation information sent from the another information processing apparatus and indicating the page turning operation performed by the presenter.

A method performed by an information processing apparatus for a system including the information processing apparatus and another information processing apparatus that are connectable to each other via a network, the method comprising:

• storing, in a memory of the information processing apparatus, a display content that includes multiple pages and is shared with the another information processing apparatus;
• displaying the display content stored in the memory on a first display of the information processing apparatus;
• displaying, on the first display, a first graphical user interface for receiving a right request to obtain a right for performing one or more input operations including at least a page turning operation on the display content;
• displaying, on the first display, a page of the display content that is same as a page displayed on a second display of the another information processing apparatus in response to a page turning operation performed on the another information processing apparatus by a presenter having the right;
