Augmented reality announcement information delivery system, and its delivery control apparatus, method, and program

Abstract

A delivery control device generates a recognition index on a notification space basis, the recognition index used to recognize the notification space, displays the recognition index in the notification space, and stores the recognition index in management information. The delivery control device instead stores an image characteristic extracted from a content to be displayed in the notification space as the recognition index in the management information. In this state, the delivery control device selects a notification space viewable on the augmented reality display terminal based on information on the position of the augmented reality display terminal held by a user and information on the position of the notification space and transmits the recognition index corresponding to the selected notification space and a notification content to the augmented reality display terminal. In response to the above, the augmented reality display terminal extracts the recognition index from the captured real-life video images and superposes the notification content in the position corresponding to the extracted recognition index in the real-life video images to generate and display augmented reality notification video images.
