Solution Overview

Problem

Conventional head-mounted displays cannot dynamically adjust virtual-world video information based on the wearer's movement, limiting immersion and interaction experiences.

Innovation Solution

An image distribution system that integrates a marker, motion sensor, and camera to control virtual-world video information displayed on a head-mounted display in real-time, allowing adjustments based on the wearer's position and movement, enabling body-sensitive Augmented Reality experiences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If virtual-world video information is displayed on a head-mounted display without dynamic adjustment, then the display function is simple and reliable, but the immersion feeling and interaction experience are poor

Engineering Contradiction:
Improveadaptability to wearer movementVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic adjustment of virtual-world video information based on real-time detection of wearer movement. The system continuously updates the displayed content according to detected movement patterns, transforming a static display system into a dynamic one that adapts to user actions, thereby improving immersion without requiring complete system redesign

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces an image distribution system as an intermediary between the wearer, the head-mounted display, and the video content source. This intermediary component processes movement detection data and adjusts video information accordingly, isolating the complexity from the core display function while enabling adaptive behavior through a dedicated mediation layer

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the head-mounted display integrates movement detection and real-time video adjustment, then the immersion feeling is improved, but the device complexity and processing requirements increase

Engineering Contradiction:
Improveuser experience qualityVSAvoidsystem integration complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the head-mounted display system into distinct functional modules: movement detection components, image processing components, and display components. The image distribution system acts as a coordinating layer that integrates these segmented functions, allowing each component to be optimized independently while maintaining overall system coherence and manageability

Inventive Principle:
Principle #1Segmentation

3Productivity

If the system processes and distributes virtual video in real-time based on movement, then the interaction quality is improved, but the processing time and computational load increase

Engineering Contradiction:
Improvevideo processing efficiencyVSAvoidprocessing delay
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent implements preliminary processing of video information and movement detection data to prepare adjusted content in advance of when it is needed for display. By pre-processing and buffering video frames based on predicted or detected movement patterns, the system reduces real-time processing delays while maintaining responsive interaction quality

Inventive Principle:
Principle #10Preliminary action

AI summary

A game system 100 to which an image display system is applied contains a head-mounted display 300 having a camera for capturing a real world and a display for displaying video information obtained by integrating real-world video information captured by the capturing part with virtual-world video information, a motion sensor 400 for detecting movement of a body of a wearer wearing the head-mounted display 300 as movement information and a marker 200 used for detecting position information of the wearer. The game system 100 controls the virtual-world video information based on the movement information and the position information. According to this configuration, it is possible to control the video information displayed on the head-mounted display according to the position and the movement of the wearer. Further, the present invention provides a method for controlling the image display system, an image distribution system and a head-mounted display.
