Camera Field-of-View Control Through Remote Viewer Voting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In web conferencing and webcasting, there is a lack of dynamic control over the field-of-view (FOV) of camera devices, which can lead to suboptimal viewing experiences as viewers cannot adjust the focus to their preference in real-time, affecting engagement and participation.
Innovation Solution
A method and system that allow multiple viewer devices to send FOV selection requests to a camera device, which aggregates these requests based on predetermined criteria, generating a control signal to adjust the camera's FOV, thereby broadcasting an adjusted image that meets the collective preference of viewers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera device uses a fixed field-of-view for broadcasting, then the system complexity is reduced and operation is simplified, but the viewer experience deteriorates as viewers cannot adjust the focus to their preference in real-time
Solution Approach 1:
The patent implements dynamic field-of-view adjustment by allowing the camera device to transition between fixed and adjustable FOV modes. Viewers can request FOV changes through viewer devices, and the system dynamically adjusts the camera FOV based on aggregated viewer preferences, making the originally static camera system adaptable to viewer needs while maintaining operational simplicity through automated control
Solution Approach 2:
The system establishes a feedback loop where viewer devices send FOV selection requests to the camera device, which then adjusts its field-of-view based on aggregated viewer input. This closed-loop feedback mechanism allows the camera to adapt to viewer preferences in real-time while the system automatically processes and implements adjustments, maintaining ease of operation despite increased adaptability
2Adaptability or versatility
If the camera device allows real-time FOV adjustments based on viewer input, then viewer engagement and experience are improved, but the system complexity increases due to multiple FOV selection requests and aggregation processes
Solution Approach 1:
The system implements self-service by automatically aggregating FOV selection requests from multiple viewer devices and generating control signals without requiring manual intervention. The camera device autonomously processes viewer feedback, determines optimal FOV adjustments, and executes changes, reducing the perceived complexity for users while maintaining high adaptability
Solution Approach 2:
The patent merges multiple FOV selection requests from different viewer devices into a single aggregate FOV selection. By combining and processing multiple inputs systematically, the system manages complexity through consolidation while still responding adaptively to viewer preferences, allowing real-time adjustments without proportionally increasing system complexity
3Productivity
If multiple viewer devices send FOV selection requests simultaneously, then the system becomes more responsive to collective viewer preference, but the processing time and complexity of aggregating selections increases
Solution Approach 1:
The system performs preliminary actions by pre-defining available FOV options and preparing the aggregation mechanism before viewer requests arrive. By having the framework ready in advance, the system can quickly process simultaneous FOV selection requests without significant processing delays, maintaining both responsiveness and efficiency

AI summary
A method for controlling a field-of-view (FOV) of a camera device. The method includes receiving, in response to the camera device capturing and broadcasting an image, a plurality of FOV selections from a plurality of viewer devices, where each of the plurality of FOV selections comprises a request to adjust the FOV of the camera device, selecting, based on a pre-determined criterion, an aggregate FOV selection from the plurality of FOV selections, and generating, in response to selecting the aggregate FOV selection, a control signal for adjusting the FOV of the camera device based on the aggregate FOV selection, where the camera device broadcasts, to the plurality of viewer devices, an adjusted image captured in response to adjusting the FOV of the camera device.
