Multi-floor Map Presentation with 2.5D Perspective View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic mapping systems for large buildings with multiple floors often present each floor as a separate map, making it difficult for users to visualize the spatial relationships between floors and features, leading to obscured information and increased bandwidth and processing resource consumption.
Innovation Solution
A communication system and method for displaying multi-floor maps, where user devices connected to a mapping server can present multiple floor maps in a 2.5-dimensional view, allowing users to select and zoom into specific floors, with animation to transition between views and highlight features, facilitating spatial understanding without requiring multiple separate map views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If each floor is presented as a separate map, then detailed information for each floor is provided, but spatial relationships between floors become obscured and user navigation becomes more complex
Solution Approach 1:
The patent combines multiple separate floor maps into a single integrated 2.5D visual representation. The system merges floor plans vertically to create a multi-level structure where users can view multiple floors simultaneously in perspective, maintaining detailed information while preserving spatial relationships and reducing the number of separate views required.
Solution Approach 2:
The patent transitions from traditional 2D floor maps to a 2.5D perspective view that adds depth perception. By rendering floor plans in perspective with vertical scaling, the system creates a third dimension effect that allows users to understand spatial relationships between floors while maintaining the detailed 2D map information.
2Loss of information
If multiple separate map views are provided for different floors, then complete floor information is available, but bandwidth and processing resource consumption increase
Solution Approach 1:
The system merges multiple floor map data sets into a single integrated 2.5D visualization, reducing the number of separate data transmissions and renders required. Users can navigate between floors within the same view context, eliminating the need to load and process multiple separate full-floor map views.
Solution Approach 2:
The system implements selective rendering where only visible portions of each floor are fully rendered at any given time. The 2.5D perspective allows the system to display partial views of multiple floors simultaneously, rendering details only for the currently visible areas while maintaining the ability to access complete floor information on demand.
3Ease of operation
If users can view multiple floors simultaneously in 2.5D, then spatial understanding is enhanced, but the complexity of the mapping system increases
Solution Approach 1:
The patent implements a 2.5D rendering system that adds depth perception to traditional 2D floor maps. By applying perspective transformation and vertical scaling to floor plan data, the system creates an intuitive three-dimensional effect that enhances spatial understanding while maintaining compatibility with existing 2D map data structures.
Solution Approach 2:
The system implements dynamic view control where the 2.5D perspective can be adjusted, rotated, and zoomed based on user interaction. The mapping system dynamically renders different floor combinations and perspective angles, allowing users to explore spatial relationships interactively while the underlying data structure remains manageable.

AI summary
Example systems, methods, and computer-readable storage media for displaying a map of a multi-floor building are presented. In one example, a first view may be presented for display. The first view may include a floor map of each of multiple floors of a building. The floor maps may be arranged in parallel according to position within the building and displayed at an angle between perpendicular to the floor maps and parallel to the floor maps. During the presenting for display of the first view, a user selection of a first one of the floor maps may be received. In response to the user selection, an animation from the first view to a second view may be presented for display. The second view may display the first one of the floor maps at an angle perpendicular to the first one of the floor maps.
