Abstract
A method, apparatus and computer program product are provided for non-occluding overlay of user interface or information elements on a contextual map. A method is provided for receiving map data and location data, determining, using a processor, relevant map elements based on the location data; and determining an information element overlay area based on the relevant map elements. The overlay areas do not occlude the relevant map elements.
Claims14
A method comprising:
- receiving map data and location data;
- determining, using a processor, relevant map elements satisfying a relevance threshold based at least in part on the location data, wherein the relevant map elements comprise at least map elements in a direction of travel;
- determining, using the processor, map elements failing to satisfy the relevance threshold;
- generating an overlay area based on the relevant map elements, wherein the generating the overlay area comprises computing a signed distance field and bit mask rendering areas corresponding to relevant map elements satisfying the relevance threshold in a first manner and rendering areas not satisfying the relevance threshold in a second manner, distinct from the first manner;
- determining an initial position for an information element or user interface element within the overlay area;
- determining an amount by which the information element or user interface element overlaps a portion of the overlay area rendered in the first manner;
- repositioning the information element or user interface element according to a gradient provided by the signed distance field in response to the portion of the overlay area rendered in the first manner being at least a predefined amount;
- generating a map based on the map data and including the bit mask rendering areas corresponding to relevant map elements satisfying the relevance threshold and the information element or user interface element;
- and
- causing the map to be rendered on a user interface.
