Directional Point of Interest Filtering for Mobile Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation applications on mobile devices do not allow users to filter local search results for points of interest based on the direction of travel, limiting the ability to find relevant locations ahead while moving.
Innovation Solution
A system and method that utilize GPS coordinates to determine the direction of travel of a mobile device and filter search results for points of interest in that direction, allowing users to receive relevant search results along their path or in the direction of travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If local search is performed in a radial pattern with current location as center, then all points of interest in all directions are found, but points of interest behind or to the sides cannot be filtered out when user is moving in a specific direction
Solution Approach 1:
The search functionality transitions from a static radial pattern to a dynamic directional filter that adapts to the user's movement direction. The system continuously updates the search criteria based on the device's current orientation and movement vector, allowing points of interest to be dynamically filtered based on the direction of travel rather than requiring manual user input for search parameters.
Solution Approach 2:
The system automatically determines the direction of travel using the device's location services and movement data, eliminating the need for users to manually specify search direction parameters. The search function self-adjusts based on the device's actual movement, providing automated directional filtering without additional user interaction.
2Productivity
If all points of interest are displayed regardless of direction, then comprehensive search results are provided, but irrelevant results increase the time to find relevant locations
Solution Approach 1:
The system extracts and filters out irrelevant search results by removing points of interest that do not lie within the directional cone defined by the user's movement direction. Only points of interest that are geographically consistent with the direction of travel are included in the search results, eliminating unnecessary information while maintaining comprehensive coverage of relevant locations.
Solution Approach 2:
The search results are differentiated by local quality based on their spatial relationship to the direction of travel. Points of interest are categorized and prioritized based on whether they lie ahead in the direction of travel, to the sides, or behind the user. This local quality differentiation allows the system to present results in a prioritized manner that matches the user's immediate needs while moving.

AI summary
A device receives global navigation satellite system coordinates associated with a mobile user device, and determines a direction of travel of the mobile user device based on the global navigation satellite system coordinates. The device creates a user-defined path based on a user-defined starting point, a user-defined destination point, and one or more user-defined intermediate points received from the mobile user device, and receives, from the mobile user device, a search request for points of interest in one of the direction of travel or along the user-defined path. The device further determines, based on the search request, one or more points of interest in the direction of travel or along the user-defined path, and provides, to the mobile user device, the determined one or more points of interest in the direction of travel or along the user-defined path.
