Sharing photos

1. A method comprising:

collecting photos associated with one or more objects, wherein the photos are collected from a plurality of users, and wherein one or more of the photos are captured using one or more respective devices that are operable to track a gaze of a user;

collecting attention information associated with the one or more objects, wherein the attention information is based on tracking gazes of the plurality of users, wherein the attention information characterizes attention of a given user with respect to a particular object, and wherein the attention information includes one or more of attention values and gaze information;

generating an attention map based on the attention information, wherein the attention map shows how much attention particular objects have received;

grouping the one or more photos into one or more groups of photos based on the attention map, wherein at least one group of photos includes photos that receive a level of attention that meets a predefined attention threshold; and

causing the one or more groups of photos to be displayed to a target user based on one or more predetermined criteria.

2. The method of claim 1 , further comprising enabling the plurality of users to have access to the one or more groups of photos.

3. The method of claim 1 , wherein at least one group of photos includes photos of at least one object from different perspectives.

4. The method of claim 1 , wherein at least one group of photos includes photos that receive a level of attention that meets a predefined attention threshold.

5. The method of claim 1 , wherein at least one group of photos includes one or more photos of at least one person who is socially connected to the target user in a social network.

6. The method of claim 1 , wherein the grouping of the one or more photos into one or more groups of photos is based on the attention map and how much attention particular obiects have received relative to other objects.

7. The method of claim 1 , wherein the attention map is based on tracking gazes of one or more of the plurality of users.

8. The method of claim 1 , wherein the generating of the attention map comprises:

receiving the gaze information;

identifying the one or more objects;

associating the gaze information with each of the one or more objects; and

determining an attention value for each of the one or more objects based on the gaze information.

9. A system comprising:

one or more processors; and

logic encoded in one or more tangible media for execution by the one or more processors and when executed operable to perform operations comprising:

collecting photos associated with one or more objects, wherein the photos are collected from a plurality of users, and wherein one or more of the photos are captured using one or more respective devices that are operable to track a gaze of a user;

collecting attention information associated with the one or more objects, wherein the attention information is based on tracking gazes of the plurality of users, wherein the attention information characterizes attention of a given user with respect to a particular object, and wherein the attention information includes one or more of attention values and gaze information;

generating an attention map based on the attention information, wherein the attention map shows how much attention particular objects have received;

grouping the one or more photos into one or more groups of photos based on the attention map, wherein at least one group of photos includes photos that receive a level of attention that meets a predefined attention threshold; and

causing the one or more groups of photos to be displayed to a target user based on one or more predetermined criteria.

10. The system of claim 9 , wherein the logic when executed is further operable to perform operations comprising enabling the plurality of users to have access to the one or more groups of photos.

11. The system of claim 9 , wherein at least one group of photos includes photos of at least one object from different perspectives.

12. The system of claim 9 , wherein at least one group of photos includes photos that receive a level of attention that meets a predefined attention threshold.

13. The system of claim 9 , wherein at least one group of photos includes one or more photos of at least one person who is socially connected to the target user in a social network.

14. The system of claim 9 , wherein at least one group of photos includes photos of at least one object that the target user has captured.

15. The system of claim 9 , wherein the attention map is based on tracking gazes of one or more of the plurality of users.
