<p>In conventional technologies, a display area of a screen cannot be used efficiently since icons or the like which display the hierarchical positions are displayed in the shape of a cross on the screen, particularly, a content list is displayed in a single column despite that there are vacant areas in the four directions of an interface whereon the icons or the like are displayed in the shape of a cross and the vacant areas cannot be used efficiently. Provided is an integrated interface device for performing a hierarchical operation for specifying a desired content list. The interface device has a function to display a content list, a content specified by the content list, or the like by efficiently using a vacant area in a lower part of the display by displaying icons which display a hierarchical relationship, for example, âdisplay in a rowâ, in an upper part of the screen, thereby clearing a large space in the lower part of the display.</p> |
