Map Presentation Overlap Reduction via 3D Perspective Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex venue maps with multiple levels, such as university buildings and shopping malls, are difficult to navigate on mobile devices due to overlapping geometric structures, which are exacerbated by small screen sizes and the challenge of presenting three-dimensional data effectively.
Innovation Solution
A method and system for optimizing map presentation by adjusting viewing parameters, such as distance and tilt, to reduce overlap between building levels in a rendered image, using a virtual camera perspective to minimize confusion and enhance navigation, and incorporating shading to provide additional three-dimensional information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple building levels are displayed simultaneously in a top-down view, then comprehensive spatial information is provided, but visual overlap increases and navigation becomes difficult
Solution Approach 1:
The patent transitions from a two-dimensional top-down view to a three-dimensional perspective view, allowing multiple building levels to be displayed simultaneously without overlap. This dimensional change enables comprehensive spatial information to be visualized while maintaining navigation clarity, as each level can be seen in its proper spatial context with appropriate vertical separation.
2Ease of operation
If a three-dimensional perspective view is used to reduce overlap, then visual clarity improves, but the complexity of viewing parameter adjustment increases
Solution Approach 1:
The system automatically determines optimal viewing parameters (viewing position, viewing direction, viewing angle) based on the building geometry and level configuration, eliminating the need for manual user adjustment. The device performs self-service by computing and applying the appropriate three-dimensional perspective parameters to achieve clear visualization of multiple levels without requiring user intervention.
3Area of stationary object
If the viewing distance is reduced to show more detail, then screen utilization improves, but overlap between levels increases
Solution Approach 1:
By switching from a top-down two-dimensional projection to a three-dimensional perspective view, the system utilizes the vertical dimension to separate building levels. This allows the viewing distance to be reduced for better screen utilization while maintaining level separation through vertical positioning, preventing overlap that would occur in a flattened two-dimensional view.

AI summary
Methods and devices are described for optimizing display of information such as map data on a mobile device. Certain embodiments may include receiving, at a mobile device, a first and second set of placement data associated with a first and second object. The mobile device may then determine overlap between a representation of the first object and the second object in a rendering of an image comprising the representation of the first object and the second object, using a set of viewing parameters, the first set of placement data and the second set of placement data. The set of viewing parameters may be adjusted to reduce overlap between the representation of the first object and the second object in the rendering of the image. In additional embodiments, 3D enhancements to two-dimensional map objects may be added to enhance the presentation of the information.
