Abstract: A display control device (110) is provided that increases the speed of a screen transition when acquiring screen data for display via a network. In the display control device (110), the display acquisition section (112) acquires not only display data corresponding to a transition target screen but also light simulation data that has small data size; and displays a simulated screen, which is a screen generated by the screen generation section (111) based on the light simulation data, until a screen based on the display data is displayed, to thereby provide a comfortable operational feeling without making a user feel a delay of a screen transition process, while reducing the memory consumption.

Abstract: A device including an update request section making an update request to update a display on a display device, and a display update section updating the display on the display device in response to the update request. In addition, the device includes a layout holding section holding layout information of each of screens hierarchically displayed on the display device, and a group assigning section, based on the layout information, assigning screens, which are displayed on the display device so as to be partially or entirely visible, to one group. The device also includes a group holding section holding group information consisting of the assigned group, and a switching request section for making a list display request to display a switching destination screen candidate list, which shows the screens included in the held group information as switching destination screen candidates in a group unit, on the display device so as to be visible.

Abstract: A display control device according to the present invention comprises: an update request section for making an update request for updating a display on a display device; a display update section for updating the display on the display device in response to the update request from the update request section; a layout holding section for, after updating of the display, holding layout information of each of screens hierarchically displayed on the display device; a group assigning section for referring to the held layout information, and assigning screens which are displayed on the display device so as to be partially or entirely visible to one group; a group holding section for holding group information consisting of the assigned group; and a switching request section for making a list display request for displaying a switching destination screen candidate list, which shows the screens included in the held group information as switching destination screen candidates in a group unit, on the display device so as t

Abstract: Provided is an operation guidance display apparatus which enables improvement of an operability for a user. When an input device (101) is changed, a display information change rule extraction section (106) extracts a function display information change rule for displaying guidance display information having been extracted. A display information change section (107) invalidates, in the guidance display information having been extracted, a display rule for operation auxiliary information corresponding to input information which is not used as input information. The display information change section (107) generates an operable GUI representing the operation auxiliary information for symbol information having been invalidated, by using the input information defined in the input information conversion table, thereby performing an appropriate operation guidance display.
