Abstract: A shared terminal includes: circuitry to control a display to display an image to a plurality of users, the plurality of users sharing a use of the shared terminal, and obtain, from a first privately-owned terminal owned by a first user of the plurality of users, first terminal identification information for identifying the first privately-owned terminal; a transmitter to transmit, to a terminal management server, an authentication request for authenticating the first privately-owned terminal to allow login of the first user into the shared terminal, the authentication request including the first terminal identification information of the first privately-owned terminal; and a receiver to receive an authentication result indicating whether the first privately-owned terminal is authenticated to allow login of the first user, from the terminal management server.

Abstract: An electronic whiteboard system includes at least one information processing system and at least one electronic whiteboard communicably connected to the information processing system. The information processing system stores, in a memory, one or more content management information records in each of which content data, user information, and information on a period of time are associated with each other. The electronic whiteboard reads, from a terminal of a user, ID corresponding to user information identifying the user, transmits, to the information processing system, the ID and information on a time at which the ID is read, receives, from the information processing system, content data included in a content management information record that includes a period of time within which the time at which the ID is read is included and user information identical to the user information corresponding to the ID, and displays the content data.

Abstract: An electronic blackboard system including an electronic blackboard and an information processing system is disclosed. The information processing system stores content data created based on data displayed on the electronic blackboard, sets of user information each specifying one of users of the electronic blackboard, and a time period indicating a schedule to display the content data on the display part.
