HMD Display Coordination for Seamless AR Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems fail to enhance user visibility by effectively coordinating images displayed on multiple units, limiting the integration of outside scenes with augmented reality images in a seamless and user-friendly manner.
Innovation Solution
A head-mounted display system that includes a first display unit for showing an outside scene and a second display unit on an information processing device, allowing the first display unit to transmit outside light and images, and the second unit to display related content, with a control system for coordinating the display modes and calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a head-mounted display shows augmented reality images, then user visibility of digital content is improved, but the integration with outside scenes becomes complex and calibration difficulty increases
Solution Approach 1:
The patent uses a camera to capture the outside scene and creates a digital copy (image data) that is then processed and displayed alongside AR content. This copying approach allows the system to work with digital representations of the real world rather than directly processing complex optical scenes, simplifying calibration while maintaining information visibility.
Solution Approach 2:
The patent introduces an image processing unit as an intermediary between the camera/corrector and the display device. This intermediary processes the captured outside scene images, applies corrections, and coordinates them with AR content, thereby managing the complexity of integrating multiple information sources without increasing overall system complexity for the user.
2Loss of information
If multiple display units are used to show related images, then the amount of information displayed increases, but coordinating the displays becomes more complex
Solution Approach 1:
The patent combines the display of corrected outside scene images and AR images into a unified visual experience through the head-mounted display. The image processing unit merges these different information sources into coordinated displays that work together seamlessly, increasing information delivery while managing coordination complexity through integrated processing.
Solution Approach 2:
The head-mounted display system serves multiple functions: it captures outside scenes, processes images, displays AR content, and coordinates multiple information streams through a single device interface. This multi-functionality allows the system to deliver diverse information while maintaining a unified user interface that doesn't increase perceived complexity.
3Ease of operation
If AR images are integrated with outside scenes, then user convenience is improved, but readability of displayed content may be compromised
Solution Approach 1:
The patent applies local quality enhancement by specifically optimizing the readability of text and content within the AR overlays and corrected outside scene images. The image processing unit applies targeted corrections and enhancements to ensure that important information remains clear and readable while being integrated with the surrounding AR environment, rather than applying uniform processing to all elements.

AI summary
A display system includes an HMD mounted on a head of a user, and a control device coupled to the HMD, the HMD includes an image display unit, with an outside scene being visible, for displaying a display image overlapping the outside scene, and a main control unit for causing an image display unit to display a display image, and the control device includes a touch panel, and a CO control unit for causing a related image related to a display content of the display image to be displayed on the touch panel.
