Focused map-based context information surfacing

1. A method comprising:

causing presentation on a client device of a map-based GUI for a social media platform, the map-based GUI comprising a map window that displays an interactive map of a geographic area, the interactive map being movable within the map window responsive to user input;

accessing, for a of plurality of users of the social media platform, location information that indicates a respective display location on the interactive map for each of the plurality of users;

accessing, for each of the plurality of users, respective context information that comprises non-location information;

causing display on the interactive map of a respective user icon for each of the plurality of users at a corresponding display location;

identifying as a focus subset of the user icons those user icons whose respective display locations are situated within a predefined focus area comprising a portion of the map window;

identifying as a non-focus subset of the user icons those user icons in the map window whose display locations are situated outside of the focus area; and

in an automated operation performed using one or more computer processor devices configured therefore, displaying in the map window the respective context information for each user icon in the focus subset, the user icons of the non-focus subset being displayed without associated context information.

2. The method of claim 1 , further comprising:

receiving user input for panning movement of the interactive map within the map window; and

responsive to movement of one or more user icons into the focus area due to the panning movement, dynamically surfacing the respective context information for the one or more user icons.

3. The method of claim 2 , further comprising:

responsive to subsequent movement of the one or more user icons out of the focus area due to the panning movement, dynamically removing from display the respective context information for the one or more user icons.

4. The method of claim 1 , wherein the focus area is defined as a fixed central portion of the map window.

5. The method of claim 1 , wherein the focus area is user-customizable in one or more of shape and size.

6. The method of claim 5 , further comprising receiving free-form user input defining the focus area.

7. The method of claim 1 , wherein the context information is user-customizable, the method further comprising:

receiving user input that selects from a predefined set of context attributes one or more context attributes that are automatically surfaced for user icons in the focus area.

8. The method of claim 1 , wherein the automatically surfaced context information includes user identifiers for the user icons.

9. The method of claim 1 , wherein the automatically surfaced context information includes timing data indicating time elapsed since generation of the respective location information.

10. A system comprising:

one or more computer processor devices; and

a memory storing instructions that, when executed by the processor, configure the system to perform operations comprising:

causing presentation on a client device of a map-based GUI for a social media platform, the map-based GUI comprising a map window that displays an interactive map of a geographic area, the interactive map being movable within the map window responsive to user input;

accessing, for a of plurality of users of the social media platform, location information that indicates a respective display location on the interactive map for each of the plurality of users;

accessing, for each of the plurality of users, respective context information that comprises non-location information;

causing display on the interactive map of a respective user icon for each of the plurality of users at a corresponding display location;

identifying as a focus subset of the user icons those user icons whose respective display locations are situated within a predefined focus area comprising a portion of the map window;

identifying as a non-focus subset of the user icons those user icons in the map window whose display locations are situated outside of the focus area; and

displaying in the map window the respective context information for each user icon in the focus subset, the user icons of the non-focus subset being displayed without associated context information.

11. The system of claim 10 , wherein the instructions further configure the system to:

receive user input for panning movement of the interactive map within the map window; and

responsive to movement of one or more user icons into the focus area due to the panning movement, dynamically surface the respective context information for the one or more user icons.

12. The system of claim 11 , wherein the instructions further configure the system to perform operations comprising:

responsive to subsequent movement of the one or more user icons out of the focus area due to the panning movement, dynamically removing from display the respective context information for the one or more user icons.

13. The system of claim 10 , wherein the focus area is defined as a fixed central portion of the map window.

14. The system of claim 10 , wherein the focus area is user-customizable in one or more of shape and size.

15. The system of claim 14 , wherein the instructions further configure the system to receive free-form user input defining the focus area.

16. The system of claim 10 , wherein the context information is user-customizable, the instructions further configuring the system to receive user input that selects from a predefined set of context attributes one or more context attributes that are automatically surfaced for user icons in the focus area.

17. The system of claim 10 , wherein the automatically surfaced context information includes user identifiers for the user icons.

18. The system of claim 10 , wherein the automatically surfaced context information includes time data indicating time elapsed since generation of the respective location information.

19. A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to perform operations comprising:

causing presentation on a client device of a map-based GUI for a social media platform, the map-based GUI comprising a map window that displays an interactive map of a geographic area, the interactive map being movable within the map window responsive to user input;

accessing, for a of plurality of users of the social media platform, location information that indicates a respective display location on the interactive map for each of the plurality of users;

accessing, for each of the plurality of users, respective context information that comprises non-location information;

causing display on the interactive map of a respective user icon for each of the plurality of users at a corresponding display location;

identifying as a focus subset of the user icons those user icons whose respective display locations are situated within a predefined focus area comprising a portion of the map window;

identifying as a non-focus subset of the user icons those user icons in the map window whose display locations are situated outside of the focus area; and

displaying in the map window the respective context information for each user icon in the focus subset, the user icons of the non-focus subset being displayed without associated context information.
