Interactive Venue Audiovisual Synchronization by Flight-Time Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rhythm video games face challenges in maintaining accuracy and synchronization of audience responses due to varying reception times of visual and audible cues based on distance from the interactive content, leading to diminished performance.
Innovation Solution
A system that compensates for these time differences by estimating flight times for audio and visual signals, allowing synchronization and accuracy to be based on the timing of response actions themselves, using a content server to adjust timestamps based on audience location and signal propagation speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If audience members are seated at different distances from the interactive content, then the venue can accommodate more audience members, but the reception time of visual and audible cues varies leading to diminished performance accuracy
Solution Approach 1:
The system performs preliminary calibration by measuring the actual reception times of visual and audible cues at multiple locations within the venue before the event. These measurements are stored and used to pre-calculate compensation values that are applied during the event to ensure accurate synchronization regardless of audience member location.
Solution Approach 2:
The system changes the timing parameters of the interactive content based on the audience member's location. By adjusting the presentation time of visual and audible cues according to measured reception times at different positions, the system maintains consistent response accuracy for all audience members regardless of their distance from the content.
2Area of stationary object
If the venue size is increased to accommodate larger events, then more audience members can be served, but signal propagation time differences increase causing synchronization issues
Solution Approach 1:
The system performs preliminary measurements of signal propagation times across the entire venue area before events are held. These advance measurements capture the time differences that would otherwise cause synchronization issues, allowing the system to pre-compensate for venue size effects.
Solution Approach 2:
The system creates a digital model or map of the venue that replicates the spatial relationships and signal propagation characteristics. This virtual copy is used to calculate and store location-specific timing compensation values, allowing the system to accurately adjust for signal propagation delays without physically modifying the venue.
3Ease of operation
If traditional timing methods are used without location compensation, then the system is simpler to operate, but audience members farther from the content experience diminished performance
Solution Approach 1:
The system automatically performs calibration measurements and calculates compensation values without requiring manual intervention during events. Once the venue is calibrated, the system self-adjusts timing for different locations based on pre-stored data, maintaining performance consistency while requiring minimal operational input.
Solution Approach 2:
The system automatically changes timing parameters based on location data, eliminating the need for manual adjustment. The complexity of parameter adjustment is hidden from operators, who simply need to input audience member locations, while the system handles the complex timing calculations automatically.

AI summary
Exemplary venues allow for members of an audience at different locations within these venues to simultaneously interact with an interactive content. The interactive content can convey one or more requisite actions to be performed by the members of the audience. However, the one or more requisite actions can reach members of the audience at different instances in time. These exemplary venues can effectively compensate for these different instances in time such that the accuracy and/or the synchronization of one or more response actions, which are performed by the members of the audience in response to the one or more requisite actions, can be characterized as no longer being dependent upon their distance from the interactive content. Rather, the accuracy and/or the synchronization of the one or more response actions by the members of the audience to the one or more requisite actions can be considered as being related to the performance, for example, timing, of the one or more response actions themselves.
