Video Feed Visual Perception Inhibitor Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for generating and processing video feeds in interactive computer simulations and real-world environments lack the ability to accurately replicate the visual effects of user-perception inhibitors, such as dizziness, fatigue, and restricted field of view, which are crucial for realistic training and performance review.
Innovation Solution
A video processing apparatus and method that captures and modifies video feeds by simulating visual-perception inhibitors, such as cropping, blurring, or shaking images, based on real-time measurements or user inputs, to create a deteriorated video feed that mimics the user's actual field of view and visual impairments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard video feeds are used to capture user actions, then complete visual information is available, but the video feed does not accurately represent the user's actual visual experience
Solution Approach 1:
The patent applies local quality by selectively degrading specific regions of the video feed based on the user's visual impairments. Different areas of the image are treated differently - some regions are blurred, cropped, or distorted while others remain clear, matching the user's actual visual experience. This resolves the contradiction by preserving relevant visual information while removing or degrading information that the user would not perceive.
Solution Approach 2:
Instead of starting with complete video information and trying to filter it, the patent inverts the approach by starting with the user's visual capabilities and generating the video feed to match those capabilities. The video processing apparatus takes the complete video feed and applies inverse operations (blurring, cropping, distorting) to transform it into the user's perceived version, thereby achieving accurate representation without losing the original complete information.
2Adaptability or versatility
If multiple data sources are integrated into a single video feed, then comprehensive coverage is achieved, but system complexity increases
Solution Approach 1:
The patent segments the video processing system into distinct functional modules: a video capture module, a visual impairment simulation module, and a composite rendering module. Each module handles a specific aspect of the task - capturing video, simulating impairments, and combining data sources. This segmentation reduces overall system complexity by making each component independent and easier to manage while achieving comprehensive coverage through the coordinated work of these modules.
Solution Approach 2:
The patent introduces an intermediary processing layer that mediates between multiple data sources and the final video output. This intermediary module receives data from various sources (cameras, sensors, user profile data) and integrates them into a unified video feed that represents the user's experience. The intermediary acts as a buffer and coordinator, simplifying the integration process and reducing the complexity of directly combining multiple data sources.
3Measurement precision
If real-time video processing is applied, then accurate representation of user experience is achieved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-characterizing the user's visual impairments and preparing the appropriate video processing parameters before the actual video capture begins. User profile data, including visual impairment characteristics, is collected and stored in advance. The video processing apparatus then uses these pre-prepared parameters to rapidly process the video feed in real-time, avoiding the need for complex calculations during the critical video capture moment and thus minimizing processing time delay.
Data Source
AI summary
A method and apparatus for generating a stream of images representing a sequence of events related to a system. The apparatus defines a field view of a user from a 3D location within an enclosed area. The apparatus comprises a network interface module for receiving, from a first data source, the sequence of events related to the system, the sequence of events comprising actions of the user performed on one or more tangible instruments of the system, and for receiving, from a second data source, images related to at least a portion of the enclosed area within the field of view of the user. The apparatus further comprises an image generator module for determining a virtual camera position in the enclosed area from the 3D location, and for rendering the stream of images from the virtual camera position to produce a rendered stream of images.
