Head Mounted Display Image Arrangement for Unobstructed Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays (HMDs) face issues such as discomfort due to blocked vision from displayed images, lack of suitable display modes for external apparatus screens, and inadequate usability, versatility, and reliability, along with high manufacturing costs.
Innovation Solution
A head-mounted display system that generates a list image by rearranging images from connected external apparatuses to optimize their arrangement for the HMD, allowing users to view external scenery while preventing image obstruction, and includes features like image acquisition, operation notification, and data volume reduction through positional and link destination information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If images from external apparatus are displayed on HMD without arrangement optimization, then the display content is preserved, but the user's front vision is blocked causing discomfort
Solution Approach 1:
The patent transforms the two-dimensional image arrangement problem into a three-dimensional spatial solution by utilizing the head-mounted display's optical path and virtual image space. Images are arranged in the periphery of the user's visual field rather than blocking the central forward view, effectively using spatial dimensionality to resolve the conflict between displaying content and maintaining unobstructed vision.
Solution Approach 2:
The patent applies different display characteristics to different regions of the visual field. The central region maintains transparency or minimal obstruction for forward vision, while the peripheral regions display image content from external apparatus. This local differentiation allows simultaneous achievement of unobstructed forward view and effective content display.
2Adaptability or versatility
If display screen of external apparatus is shown on HMD, then information accessibility is improved, but no suitable display mode exists for HMD
Solution Approach 1:
The patent changes key display parameters including image arrangement position (peripheral placement), display orientation, and potentially size scaling to adapt external apparatus screen content for HMD presentation. These parameter modifications enable the display to function effectively in the HMD environment while maintaining information accessibility.
3Loss of information
If multiple images from external apparatus are displayed, then information completeness is improved, but image arrangement becomes complex
Solution Approach 1:
The patent segments multiple images from external apparatus into distinct display regions within the HMD's visual field. Each image or information element is placed in a separate peripheral zone, allowing complete information presentation while maintaining simple individual arrangement. This segmentation prevents the complexity that would arise from trying to integrate multiple images into a single undifferentiated display area.

AI summary
A head mounted display which allows a user to visually recognize a virtual image and external scenery, includes a generation unit that generates a list image by changing an arrangement of a plurality of images of an external apparatus connected to the head mounted display to an arrangement for the head mounted display, and an image display unit that allows the user to visually recognize the generated list image as the virtual image.
