Dynamic Field of View Rendering via Frame Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital content rendering techniques are limited by a fixed field of view, which restricts the immersive experience in augmented and virtual reality environments, as they fail to utilize the expanded viewing capabilities of advanced display devices.
Innovation Solution
The use of metadata to dynamically control the field of view for different groups of frames in digital content, allowing for adaptive rendering based on user inputs or automatic detection of scene transitions, enabling varying field of view settings such as 360 degrees or reduced views, which can be applied during content creation and rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed field of view rendering is used, then device compatibility is maintained, but immersive experience is limited
Solution Approach 1:
The patent implements dynamic field of view adjustment by transitioning from fixed FOV rendering to variable FOV rendering. The system dynamically changes the field of view angle based on metadata associated with different frames, allowing the rendering to adapt between narrow and wide FOV modes. This dynamic approach resolves the contradiction by enabling FOV adaptability while maintaining compatibility with existing display devices through software-based control.
Solution Approach 2:
The patent changes the rendering parameter (field of view angle) based on frame-specific metadata. Each frame or group of frames is associated with metadata indicating the intended FOV, and the rendering system adjusts the FOV parameter accordingly. This parameter change approach allows the system to provide both narrow and wide FOV experiences using the same hardware, resolving the adaptability-complexity contradiction.
2Adaptability or versatility
If expanded field of view rendering is used, then immersive experience is improved, but conventional cinematic techniques are lost
Solution Approach 1:
The patent restores cinematic technique consistency by dynamically switching between different FOV modes based on the intended cinematic effect. Narrow FOV is used for intimate scenes requiring focus on specific elements, while wide FOV is used for expansive scenes. This dynamic restoration of cinematic intent resolves the contradiction by ensuring that the appropriate FOV is used for each scene type, maintaining reliability of cinematic techniques while providing FOV variability.
3Area of stationary object
If fixed display area is used, then device simplicity is maintained, but field of view expansion is limited
Solution Approach 1:
The patent utilizes the full display area by changing the FOV parameter rather than increasing physical display size. Through software-controlled FOV adjustment, the system can present both narrow and wide FOV content on the same fixed display area, effectively expanding the perceived viewing experience without adding hardware complexity. This resolves the contradiction by maximizing display area utilization through parameter variation.

AI summary
Techniques and system to control rendering of digital content according as having respective fields of view are described. In one example, metadata is used to assign a first field of view to be used for rendering of a first group of frames of the plurality of frames of the digital content and a second field of view to be used for rendering of a second group of frames of the plurality of frames of the digital content. Metadata is assigned to the digital content to control rendering of the first group of frames as having the first field of view and the second group of frames as having the second field of view. This metadata may then be used to control rendering of the digital content, an example of which is further described in the following.
