Interactive Map Interface with Dynamic Location Marker Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map interfaces are relatively static and lack user interaction capabilities, limiting the ability to dynamically adjust routes and view modes.
Innovation Solution
A user interface that allows users to interactively place a location marker on a map, adjust routes by moving markers, and switch between different transportation modes, with features like deletion and reordering of locations, and the option to overlay aerial photographs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If map interfaces are made static with minimal features, then system complexity is reduced, but user interaction capability and flexibility are limited
Solution Approach 1:
The system is segmented into distinct functional modules: location marker placement, route calculation, transportation mode selection, and aerial photograph overlay. Each module operates independently but integrates through standardized interfaces, allowing complex functionality to be achieved through modular components rather than monolithic design.
Solution Approach 2:
The map interface is designed as a multi-functional system that can perform diverse operations including route planning, location marking, transportation mode comparison, and aerial imagery integration. This universal design allows a single system to replace multiple specialized tools, enhancing user interaction without proportionally increasing complexity.
2Adaptability or versatility
If multiple transportation modes and route options are provided, then user flexibility is improved, but information processing complexity increases
Solution Approach 1:
The route planning system dynamically adjusts and recalculates paths based on user actions such as placing location markers or selecting different transportation modes. The system continuously updates route options and presentation without requiring complete recalculation from scratch, maintaining flexibility while managing processing complexity through incremental updates.
Solution Approach 2:
The system manages multiple transportation modes by changing key parameters such as speed, route type, and calculation algorithms based on the selected mode. Each transportation mode (e.g., driving, walking, cycling) has associated parameter sets that are activated dynamically, allowing versatile route options without permanently maintaining all processing capabilities simultaneously.
3Loss of information
If aerial photographs and multiple map layers are overlaid, then information completeness is improved, but visual clarity and processing load increase
Solution Approach 1:
The system implements aerial photograph overlay and multiple map layers selectively rather than simultaneously for all users or all the time. Base map data is always available, while aerial photographs and additional layers are loaded and displayed only when specifically requested or when they add significant value to the current view, reducing processing load while maintaining information completeness when needed.

AI summary
A map user interlace is described, including a first view transmitted from a server computer system to the client computer system, the first view including a map, and a location marker placed at the selected location on the map upon receiving a placement request indicating selection of a selected location for placement of a location marker.
