Abstract

The present technology relates to an information processing device, a display device, an information processing method, a program, and an information processing system that enable the determination of a visual field of attention in a case where an image of content in which the visual field can be freely changed is exhibited to a user. An information processing device according to one aspect of the present technology receives viewing history information including a history of a display range of each video content while being viewed, which viewing history information is transmitted from a plurality of display devices each configured to display an image of the video content in which the display range is switched within a range of the entire image by following a movement of a user, and identifies, on the basis of the history of the display range of the image of the video content at the predetermined display device, a predetermined display range of the video content within a predetermined time period thereof as a range of attention. The present technology can be applied to a device that provides content to be reproduced by an HMD.

10. The information processing device according to claim 7, wherein

on the basis of the viewing history information on a plurality of users, the identification unit selects other users who have viewed the video content resembling the video content having been viewed by a user for whom the range of attention is to be presented and, on the basis of the viewing history information on the aforementioned other users regarding the video content for which the range of attention is to be presented, identifies, as the range of attention, the display range with the largest number of overlaps between the display ranges within a time period with a maximum value of the number of overlaps between the display ranges equal to or larger than a threshold.

11. The information processing device according to claim 7, wherein

on the basis of the viewing history information on another user than a user for whom the range of attention is to be presented regarding the video content for which the range of attention is to be presented, the identification unit identifies, as the range of attention, the display range same as the display range of the another user during viewing.
