Map Tile Rendering with Dynamic Zoom and Multi-Modal Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geospatial applications face challenges in providing a seamless and intuitive user experience by uniformly displaying map tiles at the same zoom level, lacking advanced interaction methods that utilize multi-modal expressions and user intensity to enhance navigation and detail rendering.
Innovation Solution
The system employs multi-modal user expressions, including gestures, speech, and tactile pressure, to dynamically adjust zoom levels and blend map tiles, using quad tree tessellation and rendering with transparent and blur overlays to create a more detailed and appealing user experience, while also optimizing performance in low connectivity situations by focusing on zoom levels close to points of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If map tiles are displayed uniformly at the same zoom level, then the display is simple and consistent, but the user experience lacks detail and intuitiveness in navigation
Solution Approach 1:
The patent applies local quality by rendering map tiles at different zoom levels in different regions of the display. Specifically, map tiles closer to the user's current location are rendered at higher zoom levels with more detail, while tiles farther away are rendered at lower zoom levels. This creates a focal point effect that enhances navigation intuitiveness without requiring the entire map to be complex
Solution Approach 2:
The patent implements dynamics by making the zoom level of map tiles adaptive rather than static. The zoom level of each map tile dynamically adjusts based on its distance from the user's current location and the user's movement. As the user moves or changes direction, the rendering system dynamically recalculates which tiles need higher detail, creating a living, responsive display that adapts to user needs
2Ease of operation
If multi-modal user expressions and user intensity are utilized to dynamically adjust zoom levels, then navigation intuitiveness is improved, but system complexity and processing requirements increase
Solution Approach 1:
The system applies self-service by automatically analyzing user interactions and autonomously adjusting map tile rendering without requiring explicit user commands. The rendering system monitors user behavior patterns, device orientation, and interaction intensity, then self-adjusts the zoom levels and detail of map tiles accordingly. This eliminates the need for complex manual control interfaces while maintaining high navigation intuitiveness
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors user interactions with the map interface and uses this information to adjust rendering parameters. User touch patterns, device movement, and interaction duration provide feedback that triggers automatic zoom level adjustments. This creates a closed-loop system that responds to user needs in real-time without adding manual complexity
3Ease of operation
If detailed map tiles are rendered at multiple zoom levels, then user experience is enhanced, but resource consumption and processing load increase
Solution Approach 1:
The patent applies local quality by selectively rendering detailed map tiles only in regions where users are likely to interact, rather than uniformly across the entire map. Map tiles in the focal region (near the user's current location) are rendered at high detail levels, while tiles in peripheral regions are rendered at lower detail levels or not rendered at all. This significantly reduces processing energy while maintaining user experience quality in the important regions
Solution Approach 2:
The patent implements partial action by rendering only the necessary portion of map tiles at high detail levels. Instead of pre-rendering or maintaining all possible zoom levels for the entire map area, the system renders only the tiles that are currently needed based on user location and interaction patterns. This partial rendering approach reduces processing energy consumption while providing sufficient detail where users actually need it
4Productivity
If the system optimizes for low connectivity situations by focusing on nearby zoom levels, then performance is improved, but the ability to display distant locations accurately is reduced
Solution Approach 1:
The patent applies preliminary action by pre-calculating and maintaining a cache of map tiles at multiple zoom levels for regions that are likely to be needed. Before the user actually needs to view a distant location, the system proactively loads and caches the necessary tiles in the background. This allows the application to quickly switch between nearby and distant views without performance degradation, maintaining both productivity and information coverage
Solution Approach 2:
The patent implements nesting by organizing map tiles in a hierarchical structure where tiles at different zoom levels are nested within each other. Higher zoom level tiles are essentially detailed versions of lower zoom level tiles covering the same geographic area. This nested organization allows the system to efficiently manage memory and bandwidth by storing only the essential tile data at each level, enabling smooth transitions between nearby and distant views without duplicating all tile data

AI summary
Architecture that enables single and multi-modal interaction with computing devices, as well as interpreting user intensity (or liveliness) in the gesture or gestures. In a geospatial implementation, a multi-touch interaction can involve the detection and processing of tactile pressure (touch sensitive) to facilitate general navigation between two geographical points. This is further coupled with providing detailed information that facilitates navigation and turn-by-turn directions. This includes the use of time and/or pressure to release or increase the zoom level of map tiles, the touching of the two geographical points and speaking to obtain directions between these two geographical points, and the blending of tiles to create a compelling user experience, where the map is in different levels of zoom on the same view.
