determine a display size of each of the plurality of contents, based on the evaluation value calculated for each of the plurality of contents.
2. The content display device according to claim 1 , wherein
the display control circuitry is further configured to determine a display position of each of the plurality of contents, based on position information of the person corresponding to each of the plurality of contents.
3. The content display device according to claim 1 , wherein
the display control circuitry is further configured to,
according to a display order and a display time determined based on the evaluation value calculated for each of the plurality of contents, display the plurality of contents in the display region while switching the plurality of contents.
4. The content display device according to claim 1 , further comprising:
preference information collection circuitry configured to
communicate with a terminal owned by the person located in the vicinity of the display region, and
collect preference information of the person; and
display content selection circuitry configured to, based on a result of collecting the preference information, select the plurality of contents to be displayed in the display region.
5. A content display method for a computer comprising:
detecting a line-of-sight direction of a person located in a vicinity of a display region in which a plurality of contents are simultaneously displayed;
based on the line-of-sight direction, identifying a gazing point in the display region of the person;
based on a distribution of the gazing point detected in a predetermined period, identifying a gazing content at which the person is gazing;
determining a display mode of each of the plurality of contents, based on a result of identifying the gazing content; and
displaying each of the plurality of contents in the display mode determined,
wherein the content display method further comprises:
calculating an evaluation value of each of the plurality of contents, using a ratio of a total number of gazing points for each of the plurality of contents to a total number of gazing points for all of the plurality of contents detected in the predetermined period; and
determining a display size of each of the plurality of contents, based on the evaluation value calculated for each of the plurality of contents.
6. The content display method according to claim 5 , further comprising:
determining a display position of each of the plurality of contents, based on position information of the person corresponding to each of the plurality of contents.
7. The content display method according to claim 5 , further comprising:
according to a display order and a display time determined based on the evaluation value calculated for each of the plurality of contents, displaying the plurality of contents in the display region while switching the plurality of contents.
8. The content display method according to claim 5 , further comprising:
communicating with a terminal owned by the person located in the vicinity of the display region;
collecting preference information of the person; and
based on a result of collecting the preference information, selecting the plurality of contents to be displayed in the display region.
9. A content display method for a computer comprising:
detecting a line-of-sight direction of a person located in a vicinity of a display region in which a plurality of contents are simultaneously displayed;
based on the line-of-sight direction, identifying a gazing point in the display region of the person;
based on a distribution of the gazing point detected in a predetermined period, identifying a gazing content at which the person is gazing;
determining a display mode of each of the plurality of contents, based on a result of identifying the gazing content; and
displaying each of the plurality of contents in the display mode determined,
wherein the content display method further comprises:
calculating an evaluation value of each of the plurality of contents, using a ratio of a total number of gazing points for each of the plurality of contents to a total number of gazing points for all of the plurality of contents detected in the predetermined period; and
according to a display order and a display time determined based on the evaluation value calculated for each of the plurality of contents, displaying the plurality of contents in the display region while switching the plurality of contents.
