Head-Mounted Display Mode Switching for Stable VR Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted virtual reality display devices face challenges with wireless streaming issues due to router load and bandwidth limitations, affecting delay and image quality, and lack flexibility between all-in-one machines and PC helmets in terms of functionality and ease of use.
Innovation Solution
A head-mounted display device with a processor, transfer switch, wireless communication module, and display screen that can switch between communication modes based on connection to a host, enabling either host-rendered or self-rendered images, and incorporates inertial measurement modules for head and hand tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless streaming is used for all-in-one machine mode, then convenience and portability are improved, but image quality and stability deteriorate due to router load and bandwidth limitations
Solution Approach 1:
The system dynamically switches between wireless and wired communication modes based on connection status. When a host is detected, the system transitions to wired mode for stable high-quality streaming; when no host is available, it automatically falls back to wireless mode for portability, thus adapting to different usage scenarios to balance convenience and image quality
2Reliability
If wired connection to host is used for PC helmet mode, then image quality and stability are improved, but portability and ease of use deteriorate
Solution Approach 1:
The system employs dynamic mode switching that detects host availability and automatically adjusts communication mode. Users can enjoy wired connection benefits for image quality when needed, and switch to wireless mode for portability when moving around, eliminating the need to choose between the two modes permanently
3Adaptability or versatility
If the system supports both all-in-one machine and PC helmet modes, then versatility is improved, but device complexity increases
Solution Approach 1:
The head-mounted display device is designed with multi-functional capability to operate in both all-in-one machine mode (wireless) and PC helmet mode (wired). The system integrates dual communication interfaces and automatic mode detection, allowing a single device to serve multiple purposes and user scenarios without requiring separate dedicated hardware for each mode
4Ease of operation
If automatic mode switching is implemented, then ease of operation is improved, but control complexity increases
Solution Approach 1:
The system implements self-service automatic mode switching by autonomously detecting host connection status and selecting the appropriate communication mode without user intervention. The device monitors its own operational state and automatically transitions between wired and wireless modes, eliminating the need for manual configuration while keeping control logic integrated within the device itself
