Presentation system to facilitate the association of handwriting input by a participant user with a page of a presentation

摘要

A display device for displaying presentation data including multiple pages, which receives the presentation data and a page number of a page displayed from a presenter device. An image of a page having the received page number from among the multiple pages is displayed in a follow mode, and an image of any given page from among the multiple pages is displayed in a write mode. A handwritten image is detected in the write mode, associated with a page number of a page displayed, and temporarily stored when a follow mode set instruction is accepted in the write mode. If a return instruction is accepted in the follow mode, the handwritten image specified by the temporary storage data is displayed superimposed on an image of the page having a page number specified by the stored temporary storage data among the multiple pages of the presentation data.
