Stereoscopic Harmonize Transform for Virtual Reality Depth Illusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual and augmented reality environments, traditional methods for rendering far-field objects are computationally expensive and difficult to configure, leading to increased processor demand and potential revelation of false depth illusions as users become more adept at discerning depth with advanced technologies.
Innovation Solution
The method involves analyzing near-field objects to determine if they are configured for far-field perception, generating harmonize transforms based on stereoscopic projection transforms, and employing these transforms to stereoscopically render objects, preventing left and right ocular bias and maintaining the illusion of infinite or far-field depth regardless of viewing perspective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If skyboxes or near-field particle systems are used to simulate far-field objects, then the illusion of infinite depth is created, but computational costs increase and configuration difficulty increases
Solution Approach 1:
The patent uses near-field objects as copies or proxies for far-field objects. Instead of creating actual far-field environments with large coordinate systems, the system places objects close to the viewer and applies transformations to simulate their appearance at great distances. This copying approach maintains the visual illusion while avoiding the computational and configurational complexity of true far-field rendering.
Solution Approach 2:
The patent transforms the rendering parameters of near-field objects to simulate far-field characteristics. By modifying projection transforms, scale factors, and depth values, the system makes close objects appear distant. This parameter transformation allows the use of simple near-field coordinate systems while achieving the visual effect of far-field depth, thereby reducing configuration complexity.
2Reliability
If larger coordinate systems are used to prevent depth discernment, then the false-depth illusion is maintained, but processor demand increases significantly
Solution Approach 1:
Instead of using large coordinate systems that require extensive processing, the patent copies the visual appearance of far-field objects by rendering near-field objects with transformed parameters. This approach maintains the depth illusion while using a compact coordinate system, significantly reducing processor demand compared to rendering actual far-field environments.
Solution Approach 2:
The patent inverts the traditional approach by placing objects near the viewer rather than far away. Conventionally, far-field objects are rendered at large distances; this patent achieves the same visual effect by placing objects close and applying inverse transformations to simulate distance. This inversion reduces the coordinate range and computational complexity.
3Measurement precision
If stereoscopic rendering with offset transforms is used, then depth perception is enhanced, but left and right ocular bias reveals the false depth illusion
Solution Approach 1:
The patent applies asymmetric transformation adjustments to the left and right ocular renders. Instead of using identical offset transforms for both eyes, the system applies different scale factors and projection parameters to each eye's rendering of near-field objects. This asymmetric treatment compensates for the natural stereoscopic disparity, preventing the brain from detecting the artificial depth and maintaining the illusion's authenticity.
Solution Approach 2:
The patent modifies the projection transform parameters differently for left and right ocular renders to eliminate bias. By adjusting scale, offset, and depth values asymmetrically based on the desired far-field appearance, the system ensures that stereoscopic depth cues do not reveal the near-field nature of the objects, thereby maintaining illusion authenticity while preserving depth acuity.

AI summary
In various embodiments, computerized methods and systems for rendering near-field objects as perceivable far-field objects within a virtual environment are provided. A determination is made that a near-field object to be rendered is configured for far-field perception within the virtual environment. The virtual environment is operable to include one or more virtualized near-field objects that are stereoscopically rendered utilizing one or more stereoscopic projection transforms generated based at least in part on a position and orientation of a head-mounted display. A harmonize transform is generated for the configured near-field object based at least in part on one of the stereoscopic projection transforms. Based on the determination that the near-field object is configured for far-field perception, the generated harmonize transform is employed to stereoscopically render the configured near-field object as a perceivable far-field object within the virtual environment.
