Solution Overview

Problem

Fixed-type virtual reality systems are limited in providing dynamic motion-based content and are inconvenient for users, as they require wearing a head-mounted device and restrict motion.

Innovation Solution

An apparatus and method that includes transparent display units mounted on moving means, a dynamic motion sensing unit to detect 3D dynamic motions, and a control unit to synchronize virtual reality content with the detected motions, allowing for immersive virtual reality experiences without the need for a head-mounted device and without motion restrictions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-type virtual reality system is used, then the virtual reality content can be displayed according to a predetermined scenario, but the system cannot sense or respond to user motion and is limited in terms of motion generation

Engineering Contradiction:
Improvemotion responsivenessVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transitions from a fixed-type VR system to a dynamic system that can sense and respond to user motion. Motion sensing units are integrated to detect user movements in real-time, and the system dynamically adjusts the virtual reality content based on detected motion, enabling the VR experience to adapt to user actions without requiring complex mechanical movement of the display system itself.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces the need for mechanical movement of the VR display system with electronic sensing and digital content adjustment. Instead of physically moving the display to follow user motion, motion sensors detect user movement and the system electronically adjusts the virtual content position and orientation, substituting mechanical complexity with electronic control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If a head-mounted electronic device is used for virtual reality, then the user can experience virtual reality content, but the user experiences inconvenience and motion restrictions

Engineering Contradiction:
Improveuser convenienceVSAvoidmotion freedom
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent extracts the head-mounted device from the VR system, placing the display on a wall or stand instead. This removes the physical burden and motion restrictions associated with wearing a head-mounted device, while motion sensing units capture user movement to adjust the virtual content accordingly, maintaining VR functionality without the inconvenience of wearing equipment.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces motion sensing units as an intermediary between the user and the virtual reality content. These sensors detect user motion and translate it into corresponding adjustments of the virtual content on the display, serving as a mediator that connects user physical movement to the virtual experience without requiring direct physical coupling through a head-mounted device.

Inventive Principle:
Principle #24Intermediary (Mediator)
