Abstract: According to one embodiment, with respect to each of content data Cn (or an output form thereof) which is output, audience information for use in output control of the content data Cn, a condition of external information for executing the output control, and a content of the output control which is executed when the condition is satisfied, are set up, and are set in an output control information definition file 20D. From photography data including an audience photographed by an image photography unit, and from external information such as a distance to a subject, which is measured by a range finder, the external information of a kind corresponding to each content Cn that is output is acquired. By judging whether the condition of the external information is satisfied or not, the content of the output control is executed.

Abstract: A content output device includes: a display that outputs content; a communication unit that transmits at least one piece of beacon information correlated to the content which is being output by the display; and a CPU that makes responsive period information or unresponsive period information for a communication device based on the content which is being output by the display, and causes the communication unit to transmit the beacon information containing the responsive period information or the unresponsive period information, wherein the responsive period information or the unresponsive period information indicates a period which the communication device executes or does not execute an action corresponding to the received beacon information.

Abstract: The display control device includes: a distance acquirer acquiring a distance between a display surface on which an item is displayed and an operator operating the item; and a display controller displaying on the display surface an item belonging to a hierarchy level corresponding to the distance acquired by the distance acquirer from an item group including multiple hierarchized items.

Abstract: An information processing device according to the present disclosure includes a shape detector detecting a shape of a detection object, an output controller performing a control to select a virtual input device to be displayed based on the detected shape of the detection object, and to display the selected virtual input device, and a display displaying the selected virtual input device based on the control given by the output controller.
