Context-Aware Location Sharing via Environmental Signal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many users do not enable location sharing on their mobile devices due to privacy concerns or routine activities, leading to missed social interactions, as they do not recognize situations where location sharing would be beneficial and often forget to disable it after events.
Innovation Solution
A system using environmental signals, such as location and proximity to friends, to prompt users to enable location sharing and automatically disable it when conditions change, ensuring privacy and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users enable location sharing continuously, then social interactions are improved, but privacy security deteriorates
Solution Approach 1:
The patent implements dynamic location sharing by automatically adjusting the sharing state based on real-time environmental signals and contextual conditions. The system transitions between shared and private states dynamically, rather than maintaining a fixed continuous sharing mode, thus enabling social interactions when appropriate while protecting privacy when unnecessary.
Solution Approach 2:
The system changes the parameter of location sharing status (enabled/disabled) based on multiple environmental parameters including geofence conditions, device usage state, notification status, and time of day. This parameter-based control allows the system to optimize the balance between social interaction opportunities and privacy protection.
2Object-affected harmful factors
If users manually manage location sharing, then privacy control is improved, but operation complexity increases
Solution Approach 1:
The patent implements self-service privacy management where the system automatically monitors environmental signals, evaluates contextual conditions, and adjusts location sharing status without requiring manual user intervention. The system serves itself by making intelligent decisions about when to enable or disable location sharing based on pre-defined criteria and real-time conditions.
Solution Approach 2:
The system continuously monitors environmental feedback signals (geofence entry/exit, device locked/unlocked, notification received/sent, time changes) and uses this feedback to automatically adjust location sharing status. This closed-loop feedback mechanism enables the system to respond appropriately to changing conditions while maintaining user privacy preferences.
3Adaptability or versatility
If location sharing is enabled based on environmental signals, then social interaction benefit is improved, but system complexity increases
Solution Approach 1:
The patent segments the complex decision-making process into distinct evaluatable conditions: geofence conditions, device state conditions, notification conditions, and time conditions. Each condition is independently monitored and evaluated, making the overall complex system manageable through modular condition assessment rather than a monolithic decision engine.

AI summary
Environmental signals are used to determine when to prompt a user to enable location sharing on their computer devices. These environmental signals may include the current location of the user being an unusual location for the user or a location that is tagged as a known social location such as a concert venue, stadium, or park. The environmental signals may also include one or more friends of the user being near the user. If the user chooses to enable location sharing in response to the prompt, the location of the user may be shared with some or all of their friends, or just the friends that have been determined to be near the user. After some amount of time has passed, or the environmental signals have changed, the location sharing may be automatically disabled for the user.
