1. An augmented reality notification information delivery system comprising:
an augmented reality display terminal held by a user; and
a delivery control device capable of communicating with at least the augmented reality display terminal,
wherein the delivery control device includes
a storage medium that stores management information containing at least information on a position of a notification space where a recognition index representing a notification information display target portion is displayed and index information representing the recognition index,
a determination unit that determines, based on information on a position of the augmented reality display terminal and the notification space position information contained in the management information, whether or not the augmented reality display terminal is so located that the notification space falls within a field of view of the augmented reality display terminal, and
a transmission unit that transmits delivery information containing the notification information and the index information contained in the management information to the augmented reality display terminal with the augmented reality display terminal being determined to be so located that the notification space falls within the field of view of the augmented reality display terminal,
the augmented reality display terminal includes
an acquisition unit that acquires video images of a real world that falls within the field of view of the augmented reality display terminal,
a receipt unit that receives the delivery information transmitted from the delivery control device,
an extraction unit that extracts the recognition index corresponding to the index information contained in the received delivery information from the acquired real world video images, and
an augmented reality video image generation unit that displays the notification information contained in the delivery information on a display unit of the augmented reality display terminal in such a way that the notification information is superposed in a position where the recognition index in the acquired real world video images is extracted.
