Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Near-eye display mechanisms struggle to recreate an entire visual range without compromising resolution and contrast, making it challenging to display images across a user's entire viewing range effectively.
Innovation Solution
A perspective sequencing system that divides images into multiple portions and projects them in a high-speed sequence, using a rotating micromirror within the eyewear lens to shift orientations, allowing simultaneous display of the image across the entire horizontal vision range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a near-eye display mechanism is used to display images across the user's entire viewing range, then the coverage area is improved, but the resolution and contrast are compromised
Solution Approach 1:
The image is divided into multiple portions that are displayed in a high-speed sequence across different orientations. This segmentation allows the system to cover the entire horizontal vision range while maintaining high resolution and contrast in each individual portion, as each portion can be optimized independently rather than attempting to display the entire image simultaneously across the full field of view.
Solution Approach 2:
A rotating micromirror is used to dynamically shift the orientation of image portions as they are projected onto the lens. This dynamic rotation enables the system to sweep across the user's peripheral vision range, displaying different portions of the image at different angles and positions, thereby achieving comprehensive coverage without sacrificing the quality of individual image portions.
2Area of moving object
If the image is displayed across the entire horizontal vision range, then the field of view is improved, but the image quality in peripheral areas deteriorates
Solution Approach 1:
Different portions of the image are displayed with optimized quality characteristics tailored to their specific location in the user's visual field. The system maintains high resolution and contrast for each local portion while sweeping across the peripheral range, rather than attempting uniform quality across the entire field. This allows the user to perceive high-quality images throughout the expanded horizontal vision range.
Solution Approach 2:
The image portions are displayed in a high-speed periodic sequence that sweeps across the user's peripheral vision. This periodic scanning action, combined with the rotating micromirror, creates the perception of a continuous high-resolution image across the entire horizontal range by rapidly presenting optimized portions at different positions.
3Area of stationary object
If a high-speed sequence of image portions is projected, then the display coverage is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical display systems with a more streamlined approach using a rotating micromirror combined with a standard near-eye display mechanism. Instead of requiring multiple display elements or complex optical systems to cover the entire field of view simultaneously, the system uses a single display mechanism that sweeps across the field using the rotating mirror, thereby reducing overall device complexity while achieving expanded coverage.

AI summary
Systems and methods for projecting each of a chronology of images as a sequence of images using a shifting element as part of a near-eye display system are provided for use in virtual reality, augmented reality, or mixed reality systems. In some example embodiments, a chronology of images is received by a peripheral sequencing system. The system divides each image into image portions and generates sequences of image portions to recreate the images based on arrangement data. The system then causes a high-speed display of each sequence of images such that they appear simultaneous to a viewer. In some embodiments, the projection is transmitted to a shifting optical element such as a rotating micromirror that propagates a display to a user. In some embodiments, the system further detects and corrects for image and environmental distortions.
