Geotagged Content Visibility Determination Using Orientation Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mapping applications often fail to accurately determine which geotagged points of interest are visible from a user's perspective, as they may show points not visible and hide those that are visible due to factors like orientation, intervening structures, and environmental conditions.
Innovation Solution
A computer-implemented method and system that determines the visibility of geotagged content by retrieving location updates, mapping information, and orientation data to identify visible geotagged points of interest based on the user's location, direction of travel, and environmental factors, providing relevant information to the user.

Engineering Contradiction Analysis
1Quantity of substance
If mapping applications display all geotagged points of interest in the vicinity, then the quantity of information provided increases, but the accuracy of visible content display deteriorates due to showing non-visible points
Solution Approach 1:
The system extracts and displays only the subset of geotagged points of interest that are actually visible from the user's perspective, filtering out non-visible content. This is achieved by determining visibility based on user location, orientation, direction of travel, and environmental factors such as intervening structures, thereby providing accurate visible content without displaying irrelevant non-visible points
Solution Approach 2:
The system applies different visibility criteria to different geotagged points of interest based on their specific spatial relationships to the user. Each point of interest is evaluated individually considering factors such as whether it is ahead of or behind the user, the presence of intervening structures, and the user's current orientation, thereby providing locally optimized visibility determination for each content item
2Measurement precision
If mapping applications filter geotagged points of interest to show only visible content, then the accuracy of visible content display improves, but the quantity of information provided decreases
Solution Approach 1:
The system performs preliminary visibility determination for geotagged points of interest based on the user's current location, orientation, and direction of travel before displaying content. By pre-evaluating which points of interest will be visible during the user's movement, the system can provide accurate visible content information without requiring users to manually filter or search through non-visible points
Solution Approach 2:
The system dynamically adjusts the set of visible geotagged points of interest based on the user's changing location, orientation, and direction of travel. As the user moves or changes orientation, the visibility determination is updated to reflect the new perspective, ensuring that the displayed information remains accurate and relevant to the user's current viewpoint
3Measurement precision
If mapping applications consider user orientation and direction of travel to determine visibility, then the accuracy of visible content display improves, but the device complexity increases
Solution Approach 1:
The system utilizes sensors already present in the mobile device (such as GPS, compass, and accelerometer) to automatically determine user location, orientation, and direction of travel. By leveraging these existing device capabilities, the system achieves accurate visibility determination without requiring additional specialized hardware or complex external systems
4Measurement precision
If mapping applications account for environmental factors like intervening structures to determine visibility, then the accuracy of visible content display improves, but the loss of information increases due to more complex processing requirements
Solution Approach 1:
The system extracts and processes only the essential environmental factors that affect visibility, such as the presence of intervening structures between the user and geotagged points of interest. By focusing on these key factors rather than processing all possible environmental data, the system achieves accurate visibility determination while minimizing information processing overhead and maintaining efficiency

AI summary
A system and method for providing information corresponding to a set of geotagged content is provided. A location of a user operated mobile device is determined and mapping information of a target area associated with the location of the user operated mobile device is retrieved. Information corresponding to a several geotagged content in the target area is further retrieved. A visibility of each of the several geotagged content from the location of the user operated mobile device is determined based on the location of the user operated mobile device, the mapping information of the target area, and the retrieved information corresponding to several geotagged content in the target area. Information corresponding to a set of the several geotagged content determined to be visible from the location of the user is provided.
