HMD Display Controller Position-Based Image Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems lack the ability to control and synchronize the display of images between a head-mounted display device and an external device, such as a PC, to correspond to the position of the external device in the user's visual field, limiting the flexibility and coordination of the display modes.
Innovation Solution
A display system comprising a head-mounted display device and an external electronic device that includes an acquisition unit to capture images from the external device, a display controller to superimpose images on the user's visual scene, and a control unit to adjust the display based on the relative position of the external device, allowing for virtual expansion and masking of images to coordinate the display between the two devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the HMD displays all images from the external device, then the display integration is achieved, but the display coordination with the external device position is lost
Solution Approach 1:
The system dynamically adjusts the display mode based on the relative position between the HMD and external device. The display controller switches between different display modes (integration mode and coordination mode) according to real-time position information, making the system adaptable to different usage scenarios while maintaining ease of operation.
Solution Approach 2:
The system changes display parameters such as the area ratio of the external device display unit in the composite image, the position of the external device icon, and the transparency of overlays based on the detected relative position. This allows the system to optimize both display integration and coordination by adjusting parameters according to the spatial relationship between devices.
2Illumination intensity
If the external device display unit area is increased in the composite image, then the visibility of the external device is improved, but the field of view of the HMD is reduced
Solution Approach 1:
The area ratio of the external device display unit in the composite image is dynamically adjusted based on the relative position between the HMD and external device. When the external device is closer or more important, its display area increases; when it's farther or less important, the area decreases. This dynamic adjustment optimizes both visibility and field of view according to the spatial context.
3Adaptability or versatility
If the display mode is switched between integration and coordination, then the adaptability to different scenarios is improved, but the system complexity increases
Solution Approach 1:
The system uses position detection feedback to automatically determine the appropriate display mode. The display controller continuously monitors the relative position between the HMD and external device, and based on this feedback, automatically switches between integration mode and coordination mode. This feedback mechanism simplifies the user's decision-making process while maintaining high adaptability.
Solution Approach 2:
The system performs automatic display mode selection and parameter adjustment without requiring manual user input. The display controller autonomously determines the optimal display configuration based on the detected relative position, reducing the complexity of user interaction while maintaining versatile display capabilities.
