Peripheral Display Apparatus for Wide Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional extended-reality devices fail to effectively cover human peripheral vision due to limited field of view and high computational costs associated with achieving high image resolutions, resulting in a need for a solution that provides a wider horizontal field of view at lower image resolutions while being cost-effective.
Innovation Solution
A wearable peripheral display apparatus with at least two light sources positioned at opposite horizontal ends of the field of view, coupled with a processor that generates and displays two images simultaneously, supplementing a primary display apparatus to provide a wide horizontal field of view up to 220 degrees with low resolution at peripheral portions, mimicking human peripheral vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high image resolution is provided throughout the field of view, then image quality is improved, but computational cost increases
Solution Approach 1:
The patent applies different image resolutions to different regions of the field of view: high resolution for the central portion and low resolution for peripheral portions. This local differentiation reduces overall computational cost while maintaining perceived image quality, as human vision is less sensitive to details in peripheral areas.
2Area of stationary object
If display size is increased to cover wider field of view, then field of view coverage is improved, but device size and cost increase
Solution Approach 1:
The patent provides high-resolution display only for the central portion of the field of view where it is most needed, while using lower resolution for peripheral portions. This reduces the overall display area and device size requirements while maintaining adequate coverage of the extended field of view.
3Device complexity
If conventional extended-reality devices use limited display sizes, then device complexity is reduced, but field of view coverage is insufficient
Solution Approach 1:
The patent divides the field of view into distinct segments: a central portion and peripheral portions. Different display resolutions are assigned to these segments, allowing the system to achieve wide field of view coverage without requiring uniformly high-resolution displays across the entire area, thus managing device complexity.
