Audience Size Detection for Group Entertainment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video image-based control systems are limited in their ability to provide sophisticated control, making them less useful in environments requiring more complex interactions, as they primarily rely on individual participant movement within a camera's field of view without effectively aggregating inputs from large audiences.
Innovation Solution
A system that determines the size of an audience and includes modules for controlling interaction in both small and large audience environments, using frame-by-frame comparisons and vector analysis to aggregate participant inputs from multiple cameras and audio sources, allowing for cooperative or competitive control of onscreen activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual participant movement control is used, then device complexity is reduced, but group interactivity and control sophistication are limited
Solution Approach 1:
The patent merges multiple camera inputs and audio inputs into a unified control system that aggregates participant inputs. The system combines visual data from multiple cameras with audio data to create a comprehensive control signal that represents the collective intent of the audience, enabling sophisticated group interactivity without requiring each participant to have individual control devices.
Solution Approach 2:
The control system is designed to handle multiple types of inputs (video from multiple cameras, audio inputs) and adapt to different audience sizes and configurations. The system provides universal control capabilities that work whether there are a few participants or a large audience, making the system versatile for various entertainment environments without requiring separate control mechanisms for each scenario.
2Adaptability or versatility
If multiple cameras and audio sources are used to aggregate inputs, then group interactivity is improved, but device complexity increases
Solution Approach 1:
The system segments the control input aggregation process into distinct functional modules: video input processing from multiple cameras, audio input processing, and a synthesis module that combines these inputs into unified control signals. This segmentation allows each module to specialize in processing specific types of data, making the overall complex system more manageable and maintainable while still achieving sophisticated group control.
Solution Approach 2:
The patent introduces an intermediary processing layer that receives raw inputs from multiple cameras and audio sources, processes and normalizes these inputs, and then generates unified control signals. This intermediary layer acts as a mediator between the diverse input sources and the final control output, simplifying the interaction between different system components and enabling flexible configuration of the control system.
3Measurement precision
If frame-by-frame comparisons and vector analysis are used, then measurement precision is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by establishing baseline frames and pre-processing video data before actual control is needed. The system continuously processes video frames in the background, preparing motion data and updating spatial maps in advance, so that when control decisions are needed, the processed data is already ready or only minimal additional processing is required, reducing real-time processing delays.
Solution Approach 2:
The patent implements continuous processing of video and audio inputs, maintaining persistent spatial maps and motion data structures that are updated continuously rather than processed in discrete batches. This continuous action allows the system to maintain high measurement precision through ongoing frame-by-frame comparisons while distributing the processing workload over time, reducing the processing time required for any single control decision.
