Solution Overview
Problem
Current virtual reality systems, particularly HMD devices, are limited by high costs, complex setup requirements, and lack of user participation in scene design, leading to fixed virtual scenes and inadequate immersive experiences due to traditional interactive modes.
Innovation Solution
A mobile device-based virtual reality system that allows users to design and interact with virtual scenes using a head-mounted device with motion sensing, enabling immersive experiences through scene design, tracking, and natural interaction, with features like stereoscopic display and real-time posture tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HMD devices with built-in electronic parts and components are used, then VR experience is improved, but device price and host system requirements become very high
Solution Approach 1:
The patent extracts the core VR functionality from complex HMD devices and implements it using mobile devices with basic VR glasses. The complex processing and rendering are separated from the head-mounted display and performed by the mobile device's processor and graphics unit, allowing VR experience without high-end dedicated hardware
Solution Approach 2:
The patent makes mobile devices serve multiple functions - they act as both the VR content generation platform and the processing unit. The same mobile device can create, render, and display VR content, eliminating the need for separate high-performance host systems and specialized HMD electronics
2Ease of operation
If traditional interactive modes such as mouse or joystick are used, then control functionality is provided, but immersive experience is seriously affected
Solution Approach 1:
The patent replaces mechanical control devices (mouse, joystick) with motion sensing technology. The mobile device's accelerometer and gyroscope detect head movements and body posture, converting physical motion into control commands. This substitution maintains control functionality while significantly enhancing immersion by eliminating the disconnect between user action and virtual response
Solution Approach 2:
The system uses the user's natural body movements and head orientation as direct control inputs. The motion sensing device continuously tracks the user's posture and automatically translates it into navigation and interaction commands, eliminating the need for separate control devices and maintaining continuous immersion
3Stability of the object's composition
If fixed and pre-designed virtual scenes are used, then scene consistency is maintained, but user participation in design is eliminated
Solution Approach 1:
The patent transforms static, pre-designed VR scenes into dynamic, user-generated environments. The system allows users to create and modify virtual scenes in real-time based on their preferences and requirements. The scene composition changes dynamically according to user input while maintaining coherence through the system's rendering engine
Solution Approach 2:
The system incorporates feedback mechanisms where user actions and preferences influence scene generation and modification. The motion sensing data provides continuous feedback about user orientation and interaction, which the system uses to adjust and refine the virtual scene in real-time, creating a collaborative design process between user and system
4Reliability
If real scenes with themes are set up to support VR experiences, then immersive experience is enhanced, but construction process becomes complex, time-consuming and high in cost
Solution Approach 1:
The patent uses motion sensing data to capture and copy the user's real-world environment and movements, translating them into virtual space. Instead of requiring physical theme sets and real scenes, the system creates virtual representations of the user's actual surroundings, achieving immersion through digital replication rather than physical construction
Solution Approach 2:
The patent replaces the mechanical process of building physical theme sets and real scenes with software-based virtual environment generation. The motion sensing device captures user movements and the system renders corresponding virtual environments programmatically, eliminating the need for complex physical construction while maintaining or enhancing immersive experience

AI summary
A new pattern and method of a virtual reality system based on mobile devices, which may allow a player to design a virtual scene structure in a physical space and allow quick generation of corresponding 3D virtual scenes by a mobile phone; real rotation of the head of the player is captured by an acceleration sensor in the mobile phone by means of a head-mounted virtual reality device to provide the player with immersive experience; and real postures of the player are tracked and identified by a motion sensing device to realize player's mobile input control on and natural interaction with the virtual scenes. The system only needs a certain physical space and simple virtual reality device to realize the immersive experience of a user, and provides both a single-player mode and a multi-player mode, wherein the multi-player mode includes a collaborative mode and a versus mode.
