Head-Mounted Display Azimuth Control for Object Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In see-through-type head-mounted displays, it is challenging to maintain the visibility of objects within the field of view while ensuring a clear see-through area, as the display region often needs to be limited, making it difficult for objects to enter or remain in the viewer's field of view.
Innovation Solution
A head-mounted display system that includes a display unit, a detector, and a control unit capable of limiting the display region along specific axes in three-dimensional coordinates, storing images corresponding to these coordinates, and adjusting the display based on user attitude changes to enhance object visibility and searchability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display region is limited to ensure a clear see-through area, then the see-through quality is improved, but the visibility and searchability of objects in the field of view deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of image display positions based on detected user attitude changes. The display control unit monitors attitude changes in real-time and automatically adjusts image positions to compensate for user movement, ensuring objects remain visible within the limited display region while maintaining see-through quality.
Solution Approach 2:
The system uses a detector to monitor user attitude changes and feeds this information back to the display control unit, which then adjusts image display positions accordingly. This closed-loop feedback mechanism ensures that objects remain visible despite the limited display region, resolving the contradiction between see-through quality and object visibility.
2Area of stationary object
If the display region is limited, then the see-through area is ensured, but it becomes difficult for objects to enter and remain in the field of view
Solution Approach 1:
The system dynamically adjusts image display positions based on real-time detection of user attitude changes. When the user moves or changes orientation, the display control unit automatically repositions images to keep them within the visible field of view, making object searchability easy despite the limited display area.
Solution Approach 2:
The system performs self-adjustment by automatically detecting user attitude changes and repositioning images without requiring user intervention. The display control unit monitors and compensates for field of view changes autonomously, maintaining object visibility within the constrained display region.
3Illumination intensity
If images are displayed in a limited region, then see-through quality is maintained, but object visibility and searchability are reduced
Solution Approach 1:
The patent implements dynamic repositioning of displayed images based on detected user attitude changes. The system continuously monitors user orientation and automatically adjusts image positions to compensate for movement, ensuring objects remain visible and searchable within the limited display region while maintaining see-through quality.
Solution Approach 2:
The detector provides real-time feedback on user attitude changes to the display control unit, which then adjusts image display positions accordingly. This feedback mechanism ensures that objects remain visible and searchable despite the constrained display area, resolving the contradiction between see-through quality and object searchability.

AI summary
An information processing device including a display unit, a detector, and a first control unit and a method of using same. The display unit may be a head-mounted display. The display unit is capable of providing the user with a field of view of a real space and a virtual object. The detector detects an azimuth of the display unit around at least one axis and display of the virtual object is controlled based in the detected azimuth.
