A contents display device includes a display section, a touch detection section, and a control section. The control section includes: a bookmarking determination section for determining, if multiple contacts have been simultaneously detected by the touch detection section, at least one contact among the multiple contacts to be a bookmark; a bookmark-position configuration section for configuring a bookmark position, based on a contact determined by the bookmarking determination section to be a bookmark; and a return-to-bookmark-position determination section for determining, after a bookmark position has been configured by the bookmark-position configuration section, to return the content displayed on the display section to the bookmark position, based on a contact detected by the touch detection section. When the return-to-bookmark-position determination section determines to return to the bookmark position, the content displayed on the display section is returned to the bookmark position. |

1. A contents display device for displaying content, the contents display device comprising:
a display section having a single screen on which content is displayed; a touch detection section, superposed on the single screen of the display section, for detecting contact instances that operate content displayed on the display section; and a control section for controlling the content displayed on the display section, based on contact instances detected by the touch detection section, wherein the control section includes: a bookmarking determination section for, provided that multiple contact instances on the single screen have been simultaneously detected by the touch detection section, determining for the simultaneously detected multiple contact instances whether or not each simultaneously detected contact instance is stationary for a predetermined period in a region, of the display section, in which the content is displayed, and determining that a simultaneously detected contact instance that is determined to be stationary for the predetermined period is a bookmarking contact instance; a bookmark-position configuration section for configuring a bookmark position in the content displayed on the display section, based on the bookmarking contact instance; and a return-to-bookmark-position determination section for, after the bookmark position has been configured by the bookmark-position configuration section, provided that the touch detection section detects that a position of the bookmarking contact instance has slid, determining to return the content displayed on the display section to the bookmark position, and when the return-to-bookmark-position determination section has made the determination to return to the bookmark position, for returning the content displayed on the display section to the bookmark position configured by the bookmark-position configuration section, wherein when the touch detection section has simultaneously detected multiple contact instances, the touch detection section samples coordinate position of the multiple contact instances multiple times within a predetermined time period; and the bookmarking determination section determines whether each simultaneously detected contact instance is stationary on the condition that the coordinate position of the simultaneously detected contact instance does not change having been sampled for the multiple times within the predetermined time period. |
