Personalized Navigation Update Matching via User Travel Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation devices often receive irrelevant updates due to the lack of personalized matching with user travel profiles, leading to inefficient and privacy-invasive data transmission.
Innovation Solution
An apparatus and method that create a user travel profile based on locations traveled and searched, matching navigation data updates to the user's profile using a processor to determine geographical proximity, allowing only relevant updates to be offered and transmitted, respecting user privacy by controlling the data collection timeframe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation data updates are provided according to a regular schedule to all users, then the completeness and timeliness of update availability is improved, but the relevance to individual users deteriorates and unnecessary data transmission increases
Solution Approach 1:
The patent segments the universal update pool into personalized update subsets by matching navigation data updates against individual user travel profiles. The server divides the broad update category into specific relevant updates for each user based on their historical travel patterns, searched locations, and preferences, thereby resolving the contradiction between maintaining complete update availability and providing personalized relevance.
2Productivity
If navigation data updates are personalized to match user travel profiles, then the relevance and efficiency of updates is improved, but the device complexity increases due to profile matching requirements
Solution Approach 1:
The system implements self-service by automatically constructing user travel profiles from historical travel data and automatically matching navigation data updates against these profiles without requiring manual user configuration. The server autonomously performs profile construction, update matching, and personalized update provision, reducing the complexity burden on user devices while maintaining high update efficiency.
3Measurement precision
If user travel data is collected and stored to create travel profiles, then the personalization accuracy is improved, but user privacy concerns increase
Solution Approach 1:
The patent extracts only the essential travel-related data elements needed for profile construction (travelled locations, searched locations, timeframes) from the vast amount of potential user data. By selectively extracting and using only these specific data points for matching purposes, the system achieves sufficient profile accuracy while minimizing privacy intrusion compared to comprehensive data collection approaches.
4Loss of information
If all navigation data updates are transmitted to users, then the completeness of information delivery is improved, but the data transmission volume and energy consumption increase
Solution Approach 1:
The system applies partial action by transmitting only the subset of navigation data updates that are relevant to each user's travel profile rather than all available updates. The server identifies and transmits only those updates that match the user's historical travel patterns and preferences, delivering sufficient information completeness for personalized needs while significantly reducing data transmission volume and associated energy consumption.

AI summary
An apparatus comprising: at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following: based on a determined match between a user travel profile and a navigation data update, providing an option to update user navigation data for the user, in respect one or more parts of the user navigation data which are matched to the user travel profile, the user travel profile representing one or more of a location travelled by the user and a location searched by the user within a particular defined time-frame.
