Content distribution system, content distribution method, and content distribution program

A content distribution method executed by a content distribution system including at least one processor, the content distribution method comprising:

• displaying content on a plurality of user terminals;
• acquiring line-of-sight data indicating line-of-sight positions of users visually recognizing the content from two or more of the plurality of user terminals, the two or more of the plurality of user terminals including two or more viewer terminals, each of the line-of-sight positions being a position at which a corresponding one of the users is looking on a screen of a corresponding one of the two or more viewer terminals, the line-of-sight data being acquired based on tracking of eye movements of the respective users at the two or more viewer terminals;
• analyzing two or more pieces of the acquired line-of-sight data to calculate a distribution of line-of-sight positions of two or more users in the content, the distribution of line-of-sight positions indicating where lines of sight of the two or more users are located in the content;
• and
• determining, based on the calculated distribution, a mode of applying an effect to be applied to the content displayed on at least one target terminal of the plurality of user terminals, the mode of applying the effect including effect data transmitted to the at least one target terminal for causing the at least one target terminal to generate a visual effect and/or an audio effect.

A non-transitory computer-readable medium storing thereon a content distribution program that, when executed, causes a computer to execute:

• displaying content on a plurality of user terminals;
• acquiring line-of-sight data indicating line-of-sight positions of users visually recognizing the content from two or more of the plurality of user terminals, the two or more of the plurality of user terminals including two or more viewer terminals, each of the line-of-sight positions being a position at which a corresponding one of the users is looking on a screen of a corresponding one of the two or more viewer terminals, the line-of-sight data being acquired based on tracking of eye movements of the respective users at the two or more viewer terminals;
• analyzing two or more pieces of the acquired line-of-sight data to calculate a distribution of line-of-sight positions of two or more users in the content, the distribution of line-of-sight positions indicating where lines of sight of the two or more users are located in the content;
• and
• determining, based on the calculated distribution, a mode of applying an effect to be applied to the content displayed on at least one target terminal of the plurality of user terminals, the mode of applying the effect including effect data transmitted to the at least one target terminal for causing the at least one target terminal to generate a visual effect and/or an audio effect.
