Abstract

An approach is provided for grouping and de-overlapping items in a user interface. A display manager determines one or more items for rendering in a user interface. The display manager then causes, at least in part, a determination of one or more rendering locations for one or more representations of the one or more items based, at least in part, on location information associated with the one or more items. The display manager further causes, at least in part, a grouping, a de-overlapping, or a combination thereof of the one or more representations based, at least in part, on an overlapping of the one or more rendering locations. The display manager also causes, at least in part, a rendering of the one or more representations in the user interface based, at least in part, on the grouping, the de-overlapping, or a combination thereof.

Claims

1. A method comprising facilitating a processing of and/or processing (1) data and/or (2) information and/or (3) at least one signal, the (1) data and/or (2) information and/or (3) at least one signal based, at least in part, on the following:

at least one determination of one or more items for rendering in a user interface;

a determination of one or more rendering locations for one or more representations of the one or more items based, at least in part, on location information associated with the one or more items;

a grouping, a de-overlapping, or a combination thereof of the one or more representations based, at least in part, on an overlapping of the one or more rendering locations; and

a rendering of the one or more representations in the user interface based, at least in part, on the grouping, the de-overlapping, or a combination thereof.

2. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

a processing of the location information to cause, at least in part, a sorting of the one or more representations based, at least in part, on a distance of the one or more items associated with the one or more representations from a viewing location.

3. A method of claim 2, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

an association of the grouping with a closest one of the one or more representations based, at least in part, on the sorting; and

at least one determination to include one or more subsequent ones of the one or more representations in the grouping based, at least in part, on an overlapping with the closest one in the grouping; and

a rendering of a group representation in the user interface to represent the grouping without rendering the one or more representations associated with individual group members.

4. A method of claim 3, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

an input for selecting the group representation in the user interface;

a rendering of an expansion of the grouping to present the one or more representations associated with the individual group members.

5. A method of claim 4, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

a rendering the one or more representations associated with the individual group members based, at least in part, on one or more distances of the one or more items associated with the one or more representations from a centroid of the grouping.

6. A method of claim 2, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination to select a closest one of the one or more representations as an initial reference for a determination of the de-overlapping;

a processing of respective areas of a subsequent one of the one or more representations and the initial reference to determine a direction of overlap;

a modification of the one or more rendering locations associated with the subsequent one based, at least in part, on the direction of overlap; and

a designation of the subsequent one as a next reference for determining another direction of overlap for another subsequent one of the one or more representations.

7. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

a processing of the one or more rendering locations to determine one or more densities of the one or more representations in one or more regions of the user interface; and

a modification of the one or more rendering locations associated with the one or more representations that are at one or more boundaries of the one or more regions,

wherein the modification is based, at least in part, on the one or more densities, criteria for percent of the one or more representations crossing the boundaries, or a combination thereof.

8. A method of claim 7, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination of an order for processing the one or more regions based, at least in part, on the one or more densities.

9. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

a processing of a viewing location associated with the user interface to determine a viewing perspective; and

a transformation of the one or more representations based, at least in part, on the viewing perspective, the one or more rendering locations, or a combination thereof.

10. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

a processing of a viewing location associated with the user interface to determine a viewing perspective;

one or more features depicted in the user interface, the location-based user interface or a combination thereof; and

at least one determination of whether the one or more representations are occluded by the one or more features based, at least in part, on the viewing perspective, the one or more rendering locations, or a combination thereof,

wherein the one or more representations that are occluded are not rendered in the user interface.
