Map Address Display with Real-Time Street Number Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation technologies inadequately convey a user's current street address, especially in situations lacking visible landmarks or points of interest, making it difficult for users to determine their precise location along a street, boulevard, or highway.
Innovation Solution
A method and system for a wireless communications device to dynamically display address information on a map by determining the current position using a GPS receiver and presenting street numbers corresponding to that position, either visually or audibly, to enhance user awareness of their location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional navigation displays only map and route information, then the device complexity remains low, but the user cannot easily identify their current street address
Solution Approach 1:
The patent segments the address information display by separating the current street address from other map elements. The address is extracted and displayed as a distinct informational layer, allowing users to quickly identify their location without processing entire address databases or complex map data structures.
Solution Approach 2:
The patent introduces an intermediary processing layer that receives GPS coordinates, queries address information from databases, and presents the results in a simplified format. This intermediary layer handles the complexity of address resolution internally while presenting only the essential street address to the user, maintaining low perceived device complexity.
2Loss of information
If the system continuously updates and displays detailed address information, then the user awareness of location improves, but the energy consumption increases
Solution Approach 1:
The patent implements periodic updates of address information based on significant position changes rather than continuous updates. The system monitors GPS data and only refreshes the displayed address when the device moves to a new address segment, reducing unnecessary processing and energy consumption while maintaining adequate location awareness.
Solution Approach 2:
The system uses the device's existing GPS receiver and onboard address databases to self-determine current location without requiring external server queries for every position update. This self-service approach minimizes wireless communication energy consumption while maintaining accurate address display.
3Reliability
If the navigation system provides comprehensive route and POI information, then the navigation capability improves, but the ease of operation deteriorates due to information overload
Solution Approach 1:
The patent extracts and highlights only the essential current street address information from the comprehensive navigation data set. By separating the current address display from the full map and route information, the system maintains navigation accuracy while preventing information overload at critical decision points.
Solution Approach 2:
The patent applies different information densities to different parts of the interface. The current address area receives focused, high-visibility presentation with simplified formatting, while other map areas maintain detailed information. This local quality differentiation allows users to quickly grasp their location without being overwhelmed by comprehensive navigation data elsewhere on the screen.

AI summary
A method of displaying a map on a device includes determining position information of a position on the map, displaying a graphical position indicator representing the position on the map, determining address information corresponding to the position on the map, and presenting the address information via a user interface of the device by displaying a street number on the map adjacent to the graphical position indicator.
