Abstract: A position of a user is recognized. A display unit (102) displays a content-display-frame (112). A determination unit (103) determines whether the position of the user is within a predetermined range from a wall surface (12) or not. The display control unit (104) configured to display a content-display-frame on a floor surface (11) when the position of the user is farther than the predetermined range from the wall surface, and configured to display an operation input area (113) that receives an operation input from the user on the wall surface while displaying a content-display-frame to span from the floor surface to the wall surface when the position of the user is within the predetermined range from the wall surface.

Abstract: A queue management device includes: a queue detection unit that, on the basis of a detection result of forming elements at a site subject to queue management, detects the state of the queue; a guidance position determination unit that, on the basis of the state of the queue detected by the queue detection unit, determines a guidance position where a guidance should be displayed; and a guidance display control unit that controls a display device such that the guidance is displayed at the guidance position determined by the guidance position determination unit.

Abstract: A linking system includes a first linking control device which performs control such that a first building management system that manages building facilities provided in a first building and a first device connected to an internet to linked to realize a specific function, wherein the first linking control device includes a memory which memories linking procedure information indicating procedures for realizing the linking of the specific function; and a linking controller which controls (i) an output to the first device in response to an input from the first building management system or (ii) an output to the first building management system in response to an input from the first device so as to realize the specific function based on the linking procedure information stored in the memory.
