Location-Aware Sticky Notes for Privacy-Controlled Social Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing social networking systems do not effectively allow users to leave electronic, location-triggered note messages that are accessible only to users who are at or near a specific location, limiting the relevance and privacy of location-based interactions.
Innovation Solution
A system that enables a first user to create a location-triggered note associated with a specific location, which is transmitted to a second user only when they are at or near that location, using GPS coordinates and privacy settings to control accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If location-triggered notes are transmitted to all users, then information dissemination is improved, but privacy control deteriorates
Solution Approach 1:
The patent applies local quality by making note visibility location-dependent. Notes are not uniformly visible to all users but are selectively displayed based on the viewer's geographic proximity to the note's location. This resolves the contradiction by allowing broad information dissemination to nearby users while maintaining privacy control through location-based filtering.
Solution Approach 2:
The patent implements dynamics by making note accessibility dynamic rather than static. Notes automatically appear or disappear from user views based on real-time location data and proximity calculations. This dynamic approach enables information to flow freely to relevant users while automatically protecting privacy for users outside the designated area.
2Adaptability or versatility
If location-triggered notes are made accessible to nearby users, then social interaction is improved, but information relevance deteriorates
Solution Approach 1:
The patent applies feedback by using location data to dynamically control note visibility. The system continuously monitors user locations and automatically determines which notes should be displayed based on proximity to note locations. This feedback mechanism ensures that only socially relevant notes are shown to appropriate users, maintaining both social interaction and information relevance.
3Measurement precision
If GPS location tracking is continuously monitored, then location accuracy is improved, but energy consumption deteriorates
Solution Approach 1:
The patent implements periodic action by updating location tracking only when necessary for note visibility determination. Rather than continuous monitoring, the system periodically checks user locations and compares them against note locations to determine if proximity thresholds are met. This periodic approach maintains sufficient location accuracy for the application while significantly reducing energy consumption compared to continuous tracking.

AI summary
In one embodiment, a request to share a message is received from a first user. The request includes a first location, the message, and note-access criteria for sharing the message based on one or more groups of second users. A particular second user is identified having a second location that is within a threshold distance of the first location. Based on the note-access criteria and one or more groups associated with the particular second user, it is determined that the message should be shared with the particular second user, the message is sent to the particular second user, and a location of the first user is determined to be within a predetermined distance from the first location. If the first user is currently within the predetermined distance, a notification is sent to the first user informing the first user that the message was sent to the particular second user.
