Methods and devices for selectively presenting a user interface in a dual screen device. More particularly, the method includes providing a gallery for the dual screen device. The gallery can present one or more images in a user interface. The gallery user interface can adapt to changes in the device configuration. Further, the gallery can display images or videos in the various configurations.

According to an aspect, an information display device includes a display unit, a visual line detector, and a control unit. The display unit displays information in a scroll region, which is provided in at least a part of a screen of the display unit, while scrolling the information. The visual line detector detects a visual line position of an operator with respect to the scroll region. The control unit controls a scroll speed, at which the information is scrolled in the scroll region, based on the visual line position detected by the visual line detector.

A display system displays, on each of a plurality of display devices arranged side by side, among image data of a plurality of pages, each of image data of the number of display devices, and reflects input information, which indicates information input by a user, on image data displayed on a master display device among the plurality of display devices. Moreover, the display system displays, on each of the plurality of display devices, among the image data of the plurality of pages, each of image data which is obtained by shifting the image data of the number of display devices in accordance with an operation on a page operation unit. Thereby, a viewer is able to view image data of several pages at once, and it is possible to reflect information input by a user even when image data of a target page is shifted backward or forward.

A system for determining a gaze direction of a user of a wearable device is disclosed. The system may include a primary lens, an illuminator, an image sensor, and an interface. The illuminator may include a light guide, may be disposed at least partially on or in the primary lens, and may be configured to illuminate at least one eye of a user. The image sensor may be disposed on or in the primary lens, and may be configured to detect light reflected by the at least one eye of the user. The interface may be configured to provide data from the image sensor to a processor for determining a gaze direction of the user based at least in part on light detected by the image sensor.

An example information processing apparatus determines whether an orientation of a display unit capable of being held by a user is in a first state or in a second state. If it has been determined that the orientation of the display unit is in the first state, the information processing apparatus sets, in a predetermined area, a display range to be displayed in the display unit, in accordance with the orientation of the display unit. If it has been determined that the orientation of the display unit is in the second state, the information processing apparatus sets the display range, regardless of the orientation of the display unit.

Provided is a display control device including: a voice receiver configured to receive a voice utterance from a user; a communication unit configured to receive information for the voice utterance from a server via a network; and a controller configured to select an item corresponding to the voice utterance on the basis of the information that has been received, and configured to control an action in response to the item that has been selected, in which the item includes a first item in an inside of a display screen and a second item that becomes displayable by scrolling, and the controller selects either the first item or the second item on the basis of the information that has been received. The present technology is applicable to, for example, a television receiver.

There is provided a technique for easily determining a position of a page that is displayed in an electronic document. A television receiver (1) includes a table-of-contents image generating unit (112) that generates a table-of-contents image which represents a table of contents of an electronic document and which is to be displayed on a display, the table of contents having two or more layers; and a text image generating unit (113) that generates a text image which represents a text of the electronic document and which is to be displayed on the display. The table-of-contents image generating unit changes an upper-level item that is opened in a generated table-of-contents image to a changed upper-level item, in response to a change of an upper-level item including an item corresponding to the text image generated by the text image generating unit.
