Abstract: A display-controlling device includes: a display-controlling unit that controls a display unit to display an image indicating an item selected upon receipt of an instruction at a receiving unit, wherein if a first image indicating a first selected item is displayed at a first position, and an item instructed to be selected changes from the first selected item to a second selected item, the display-controlling unit causes there to be displayed, without erasure of the first image, a second image indicating the second selected item at a second position, which position is reached from the first position by movement in the first direction by an amount based on a position of the second selected item as viewed from the first selected item, with simultaneous movement in a second direction other than the first direction by a predetermined amount.

Abstract: A content management system includes a conversion a section, a display data storing section, a field section, an operation section and a management section. The conversion section converts content data into display data which is to be written into an electronic paper. The display data storing section stores the display data. The field storing section stores field data which includes identification information of a first user belonging to a field and identification information of the display data. The operation section accepts a request from a second user. The management section that allows, when the identification information of the first user contained in the field data coincides with identification information of the second user contained in the request accepted by the operation section, the display data indicated by the identification information contained in the field data to be written into the electronic paper.
