Wearable Terminal Display Positioning for Partial Image Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable terminal apparatuses for virtual reality (VR), mixed reality (MR), and augmented reality (AR) face challenges in dynamically adjusting the display position of virtual images and function bars within the visible region of the user, which can lead to usability issues when the virtual image is positioned outside the user's field of view.
Innovation Solution
The wearable terminal apparatus includes a processor that causes a display unit to show a virtual image located in a space and changes the display position of a partial image, such as a function bar, when a predetermined condition is met, ensuring that the virtual image and its components remain within the user's visible region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the virtual image is displayed at a position outside the user's field of view, then the virtual space can be expanded, but the usability and accessibility of critical elements like function bars deteriorate
Solution Approach 1:
The display content is segmented into two parts: the virtual image (which can be positioned freely in the virtual space) and the partial image such as the function bar (which is dynamically repositioned). This segmentation allows the virtual space to be expanded while keeping critical interactive elements within the user's field of view for maintained usability.
Solution Approach 2:
The display position of the partial image is made dynamic rather than fixed. The system continuously monitors the user's field of view and automatically adjusts the position of the function bar to ensure it remains within the visible region, while the virtual image can maintain its position outside the field of view to expand virtual space.
2Device complexity
If the display position of the virtual image is fixed, then the system complexity is reduced, but the adaptability to user movement and viewing conditions deteriorates
Solution Approach 1:
The system implements self-service by automatically detecting the user's field of view and autonomously adjusting the display position of the partial image without requiring user intervention. The processor monitors viewing conditions and dynamically repositions the function bar to maintain visibility, providing adaptability while keeping the user interface simple.
Solution Approach 2:
The system uses feedback from field of view detection to dynamically adjust the display position. The processor continuously monitors the user's viewing conditions and uses this feedback to automatically reposition the partial image, creating a closed-loop system that adapts to changing conditions without increasing apparent system complexity for the user.
3Ease of operation
If the partial image is always displayed within the visible region, then the ease of operation is improved, but the flexibility in virtual image positioning deteriorates
Solution Approach 1:
The display system is segmented into a virtual image portion and a partial image portion (function bar). The virtual image can be positioned flexibly outside the field of view to maintain spatial accuracy, while the partial image is separately managed and repositioned within the visible region to ensure ease of operation and accessibility.
Solution Approach 2:
Different parts of the display have different positioning requirements. The virtual image maintains its local position in the virtual space for accuracy, while the function bar is dynamically repositioned locally within the field of view to ensure accessibility. This local quality approach allows each element to optimize its positioning independently.

AI summary
A wearable terminal apparatus to be worn by a user for use includes a display unit and at least one processor. The at least one processor causes the display unit to display a virtual image located in a space. The at least one processor changes a display position of a partial image when a predetermined condition is satisfied, the partial image being an image of a partial region included in the virtual image.
