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

VSEngineering 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

Engineering Contradiction:
Improvenumber of virtual screensVSAvoidoperability of virtual screens
Core Design Contradiction:
Quantity of substanceVSEase of operation

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvenumber of virtual screensVSAvoidfield of view clutter
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvescreen positioning systemVSAvoidadaptability to device movement
Core Design Contradiction:
Device complexityVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #23Feedback
