[Solution] A meeting assistance system includes: a presentation document storage unit 3 that stores a presentation document; an authority, imparting unit 5 that grants document manipulation rights to a participant; a document sharing unit 7 for sharing the presentation document with participants; and a presentation document updating unit 9 that, on the basis of a manipulation from one or more authorized participants to which document manipulation rights have been granted, manipulates and updates the presentation document stored in the presentation document storage unit 3. When the document sharing unit 7 is sharing a first presentation document with a plurality of participants, if one or more authorized participants manipulates the first presentation document, the updated first presentation document shared in real time with the plurality of participants. ## Claims ### Claim 1 A meeting assistance system, which comprises a computer comprising a processor and a program, wherein when executed on the processor, the program makes the computer to execute the program, comprising: a presentation document storage unit (3) that stores a presentation document; an authority imparting unit (5) that grants a document operation right to a participant; a document sharing unit (7) for sharing the presentation document with a participant; and a presentation document updating unit (9) that operates and updates the presentation document stored in the presentation document storage unit (3) based on an operation from a plurality of right-holding participants to which a document operation right has been granted by the authority imparting unit (5), wherein the document sharing unit has instructions to cause in a case where the document sharing unit (7) is sharing a certain presentation document stored in the presentation document storage unit (3) with a plurality of participants, wherein when the plurality of right-holding participants operate the certain presentation document, the updated certain presentation document is shared in real time with the plurality of participants, for a certain image content as a content included in the certain presentation document, in a case where the meeting assistance system concurrently receives commands to move the certain image content from two or more right-holding participants the presentation document updating unit (9) changes color of the certain image content, and updates the certain presentation document, wherein the certain image content with changed color is shared in real time with the right-holding participants, the document sharing unit has instructions to cause in a case where the meeting assistance system concurrently receives the commands to move the certain image content from the two or more right-holding participants, corresponding and respective assumed images of the certain image contents reflecting the concurrently received commands are simultaneously shared and displayed to the plurality of participants, and the presentation document storage unit (3) exists on a web server. ### Claim 2 (depends on 1) The meeting assistance system according to claim 1, wherein when commands from one of the participants to correct title in the presentation document are issued, the title is locked for correction. ### Claim 3 A computer-implemented method for assisting a computer implemented meeting, comprising executing on a processor the steps of: storing a presentation document; granting a document operation right to a participant or participants of the meeting; sharing the presentation document with the participants; operating and updating the presentation document based on an operation from a plurality of right-holding participants to which a document operation right has been granted, wherein, when a certain presentation document is shared with a plurality of participants and the plurality of right-holding participants operate the certain presentation document, the updated certain presentation document being shared in real time with the plurality of participants, and for a certain image content as a content included in the certain presentation document, when commands to move the certain image content from two or more right-holding participants are concurrently issued, changing color of the certain image content and updating the certain presentation document, wherein the certain image content with changed color is shared in real time with the right-holding participants, in a case where the meeting assistance system concurrently receives the commands to move the certain image content from the two or more right-holding participants, corresponding and respective assumed images of the certain image contents reflecting the concurrently received commands are simultaneously shared and displayed to the plurality of participants. ### Claim 4 (depends on 3) The computer-implemented method according to claim 3, wherein the method further executes on the processor the step of locking title in the presentation document for correction when commands from one of the participants to correct the title are issued.
