US 2018/0005434 A1 · System and Methods for Interactive Hybrid-Dimension Map Visualization

Abstract

A navigational system includes a hybrid-dimensional visualization scheme with a multi-modal interaction flow to serve for digital mapping applications, such as in car infotainment systems and online map services. The hybrid-dimensional visualization uses an importance-driven or focus-and-context visualization approach to combine the display of different map elements, including 2D map, 2D building footprint, 3D map, weather visualization, realistic day-night lighting, and POI information, into a single map view. The combination of these elements is guided by intuitive user interactions using multiple modalities simultaneously, such that the map information is filtered to best respond to the user's request, and presented in a way that presents both the focus and the context in a map in an aesthetic manner. The system facilitates several use cases that are common to the users, including destination preview, destination search, and virtual map exploration.

Dependent claims

A method for generating map graphics including two-dimensional and three-dimensional elements comprising:

generating with a processor a graphical display of a two-dimensional base map with a display device;
receiving with a multi-modal input device a user selection of a region of interest in the two-dimensional base map, the region of interest corresponding to only a portion of the two-dimensional base map;
identifying with the processor a first footprint region in the two-dimensional base map, the first footprint region including the region of interest and a first portion of the two-dimensional base map outside of the region of interest;
generating a three-dimensional graphical display of at least one building, terrain feature, or landmark located within the region of interest with the graphical display device;
and
generating a first two-dimensional graphical display in the first footprint region including at least one graphical element not present in the two-dimensional base map with the graphical display device.

3 more elements

An in-vehicle mapping system comprising:

a graphical display device configured to display two-dimensional and three-dimensional graphics including a map and features on a map;
a multi-modal input device;
and
a processor operatively connected to the graphical display device and the multi-modal input device, the processor being configured to:
generate a graphical display of a two-dimensional base map with the graphical display device;
receive with the multi-modal input device a user selection of a region of interest in the two-dimensional base map, the region of interest corresponding to only a portion of the two-dimensional base map;
identify a first footprint region in the two-dimensional base map, the first footprint region including the region of interest and a first portion of the two-dimensional base map outside of the region of interest;
generate a three-dimensional graphical display of at least one building, terrain feature, or landmark located within the region of interest with the graphical display device;
and
generate a first two-dimensional graphical display in the first footprint region including at least one graphical element not present in the two-dimensional base map with the graphical display device.
