Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation apps for mobile devices are primarily designed for driving and do not effectively provide pedestrian-oriented navigation, failing to utilize pedestrian walkways, cut-throughs, indoor paths, and real-time feedback for efficient navigation.
Innovation Solution
A pedestrian-oriented navigation app for mobile devices that receives destination information, accesses pedestrian-oriented mapping data and routing, determines the user's current location and direction using GPS and compass data, and provides real-time feedback and alerts if the user deviates from the route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current navigation apps are used for pedestrian navigation, then the apps can provide routing directions, but they fail to provide pedestrian-oriented routes including walkways, cut-throughs, and indoor paths
Solution Approach 1:
The patent changes the routing parameters from vehicle-centric street networks to pedestrian-centric pathways by incorporating multiple data sources including OpenStreetMap, Google Maps, and indoor mapping data. This allows the system to calculate routes based on pedestrian walkability parameters rather than vehicular traffic parameters, resolving the contradiction between adaptability and reliability.
Solution Approach 2:
The navigation app is enhanced to serve multiple functions: it provides both traditional vehicle navigation and specialized pedestrian navigation with features like walkway detection, crosswalk identification, and indoor path routing. This multi-functionality allows the same app to reliably serve different user needs without compromising pedestrian-oriented route accuracy.
2Productivity
If pedestrian-oriented mapping data is implemented, then navigation efficiency improves, but the system complexity increases due to multiple data sources and real-time processing requirements
Solution Approach 1:
The patent segments the navigation system into distinct modular components: a data acquisition module that collects mapping data from multiple sources, a route calculation module that processes pedestrian-specific parameters, and a real-time feedback module that monitors pedestrian position and provides guidance. This segmentation allows each component to be optimized independently, improving overall navigation efficiency while managing system complexity through modular architecture.
Solution Approach 2:
The system performs preliminary processing of mapping data from multiple sources during off-peak times, pre-calculating pedestrian pathways and storing optimized route data. This preliminary action reduces the computational burden during real-time navigation, maintaining high navigation efficiency while preventing system complexity from becoming unmanageable during active use.
3Measurement precision
If real-time feedback and deviation detection are added, then user guidance accuracy improves, but energy consumption increases due to continuous GPS and compass data processing
Solution Approach 1:
Instead of continuously processing GPS and compass data at maximum frequency, the patent implements periodic sampling with adaptive intervals. The system monitors pedestrian position at optimized intervals based on current navigation phase and deviation risk, maintaining high measurement precision for deviation detection while significantly reducing energy consumption compared to continuous maximum-frequency tracking.
Solution Approach 2:
The navigation system leverages the mobile device's existing sensor suite (GPS, compass, accelerometer) that are already running for other purposes. By integrating with these self-service sensors and utilizing their existing power management, the system achieves accurate real-time feedback without requiring additional dedicated hardware or excessive energy consumption beyond what the device already consumes for basic location services.
Data Source
AI summary
Methods, apparatuses, and computer-readable media for providing a pedestrian-oriented navigation app for a mobile device. Destination information is received from a pedestrian using a mobile device. The mobile device retrieves pedestrian-oriented mapping data and routing for the navigation of the pedestrian to the destination, determines a current location and direction of the pedestrian based upon GPS data and compass data retrieved from the device, and displays the current location and direction of the pedestrian along with a route for the pedestrian to the destination on the user interface of the mobile device based on the pedestrian-oriented mapping data and routing. If the mobile device detects that the pedestrian has deviated from the route, the mobile device alters the display on the user interface to alert the pedestrian to the deviation.
