    摘要: A screen sharing system is configured to perform screen sharing between a first information processing apparatus and a second information processing apparatus. The first information processing apparatus is configured to acquire, as screen-sharing information, an image displayed on the first information processing apparatus, and transmit the screen-sharing information to a first server, when a data amount of the screen-sharing information is below a threshold value, and transmit the screen-sharing information to a second server and transmit, to the first server, storage destination information indicating a storage destination of the screen-sharing information, when the data is greater than or equal to the threshold value. The second information processing is configured to display, on the second information processing apparatus, an image based on the screen-sharing information received from the first server, or received from the second server based on the storage destination information received from the first server.

    摘要: An electronic blackboard includes a display that displays visible information. The electronic blackboard includes a coordinate detector configured to detect coordinates of an object in the display; a number detector configured to detect a number of the objects in the display, based on the detected coordinates of the object; a time measurer configured to start measuring a predetermined time in response to detecting a first object; and a mode determiner configured to determine that the electronic blackboard is in a handwriting mode in which the visible information is displayed based on the coordinates, upon determining that a second object is not detected upon completing to measure the predetermined time, and to determine that the electronic blackboard is in a gesture mode in which an operation with respect to the visible information is accepted, upon determining that the second object is detected before completing to measure the predetermined time.
