Virtual Screen Positioning to Reduce Overlap in Head-Mounted Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of cumbersome user view and difficulty in operating multiple virtual screens displayed on an information processing device, such as a head-mounted display, due to overlapping fields of view and lack of efficient screen management.
Innovation Solution
The position of virtual screens associated with mobile terminals is adjusted within a virtual space based on the movement of the mobile terminals in real space, ensuring that virtual screens move in relation to the physical position changes, thereby optimizing screen organization and reducing overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple virtual screens are displayed on a head-mounted display, then the information processing capability is improved, but the field of view becomes cumbersome and operability deteriorates
Solution Approach 1:
The patent transitions from two-dimensional screen stacking to three-dimensional spatial arrangement of virtual screens. Multiple virtual screens are positioned at different locations in the user's field of view, allowing simultaneous access to multiple screens without overlapping or requiring manual navigation through layered interfaces.
Solution Approach 2:
The patent divides the virtual display space into multiple independent regions, each containing a separate virtual screen. This segmentation allows each screen to be independently positioned and operated, reducing the cognitive load and physical effort required to manage multiple displays.
2Quantity of substance
If multiple virtual screens are displayed, then the display capacity is improved, but the field of view becomes cluttered and visibility is reduced
Solution Approach 1:
The patent utilizes three-dimensional spatial distribution to arrange virtual screens at different positions and depths within the user's field of view. This dimensional expansion allows multiple screens to coexist without overlapping, maintaining clear visibility of each screen while accommodating multiple displays simultaneously.
3Device complexity
If virtual screens are positioned statically, then the system complexity is reduced, but the adaptability to user movement and device position changes is worsened
Solution Approach 1:
The patent implements dynamic positioning of virtual screens that automatically adjusts screen locations based on the user's head movements and the physical positions of connected mobile terminals. This dynamic adaptation maintains optimal screen arrangement without requiring manual repositioning, balancing system complexity with adaptability.
Solution Approach 2:
The system continuously monitors user head position and mobile terminal locations, using this feedback information to automatically adjust virtual screen positions. This closed-loop control ensures screens remain optimally positioned relative to the user's field of view and device orientations.
