AR Event Viewing Registration Using Crowd-Sourced Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems struggle to accurately provide individualized content to viewers of sporting events, as they often rely on broadcaster-selected graphics and fail to account for diverse viewer perspectives, especially in environments with organic shapes and changing conditions.
Innovation Solution
A system that uses specific feature detection and iterative techniques to correlate a user's camera view with real-world coordinates, employing features like ridge lines and edges of man-made structures, and incorporates crowd-sourced images to enhance registration accuracy, utilizing GPS, compass, and inertial measurement units for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional broadcast media are used to convey event information, then production costs and distribution infrastructure requirements are reduced, but the ability to provide real-time, interactive, and visually engaging content is limited
Solution Approach 1:
The system segments the event viewing experience into multiple content streams (live video, augmented reality overlays, statistical data, user interactions) that can be delivered through different channels. The AR interface segments the visual field to display relevant information layers without obscuring the main event view, allowing versatile content delivery while managing complexity through modular design.
Solution Approach 2:
The patent introduces an intermediary AR interface layer between the user and the event broadcast. This intermediary layer processes and presents information through augmented reality overlays, enabling versatile content delivery without requiring users to directly interact with complex broadcast infrastructure. The intermediary handles the complexity of data processing and presentation.
2Loss of information
If multiple camera angles and real-time streaming are implemented, then viewer engagement and information completeness are improved, but bandwidth requirements and system infrastructure complexity increase
Solution Approach 1:
Instead of transmitting all possible camera angles and event data continuously (excessive action), the system transmits only the essential live video stream and pre-load relevant information. The AR interface then selectively retrieves and displays only the necessary information (partial action) based on event context and user interests, reducing infrastructure complexity while maintaining information completeness.
Solution Approach 2:
The system performs preliminary actions by pre-loading event information, statistics, and contextual data before the live broadcast. This allows the AR interface to access and display relevant information instantly during the event without requiring continuous high-bandwidth transmission of all possible data, reducing infrastructure complexity while maintaining information completeness.
3Ease of operation
If interactive features and real-time updates are added to broadcast, then viewer engagement is improved, but production costs and operational complexity increase
Solution Approach 1:
The AR interface enables self-service interaction where viewers can independently access, filter, and display information relevant to their interests without requiring complex production operations. The system automatically retrieves and presents information based on user selections and event context, improving ease of operation while reducing production operational complexity through automated information delivery.
Solution Approach 2:
The system incorporates feedback mechanisms where viewer interactions and preferences are captured and used to dynamically adjust information delivery. This feedback loop allows the AR interface to adapt to user needs in real-time, improving ease of operation while managing operational complexity through automated response to user actions.
4Illumination intensity
If augmented reality overlays and real-time graphics are implemented, then visual engagement and information delivery are improved, but processing requirements and system resources increase
Solution Approach 1:
The AR interface applies local quality by rendering detailed graphical overlays and information only in specific regions where needed, rather than processing the entire video stream uniformly. This selective processing reduces overall resource consumption while maintaining high visual engagement and information density in critical areas.
Solution Approach 2:
The system uses copying by creating simplified representations and overlays of event information rather than processing every pixel and detail of the original video. The AR interface copies relevant information into overlay layers that can be processed and displayed with lower computational resources while maintaining visual engagement.

AI summary
Augmented reality systems provide graphics over views from a mobile device for both in-venue and remote viewing of a sporting or other event. A server system can provide a transformation between the coordinate system of a mobile device (smart phone, tablet computer, head mounted display) and a real world coordinate system. Requested graphics for the event are displayed over a view of an event.
