Self-contained Mixed Reality Headset Computing Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display (HMD) systems are tethered to computer systems, limiting user mobility and immersion in virtual reality (VR) and augmented reality (AR) experiences, as users cannot freely move or interact with their environment.
Innovation Solution
A self-contained HMD system with modular design, incorporating depth sensing technology, a wireless color LED controller, and haptic feedback, allowing users to experience mixed reality by spatially mapping their surroundings and enabling interaction with both virtual and real environments without cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If HMD systems are tethered to computer systems to power the headset and drive the VR experience, then the computing power and processing capability are improved, but user mobility and freedom of movement are reduced
Solution Approach 1:
The patent extracts the computing components (processor, memory, battery) from the external computer system and places them within the HMD headset itself, creating a self-contained system that eliminates the need for tethering while maintaining full computing capability for driving VR/AR experiences
Solution Approach 2:
The system is segmented into modular components including the HMD headset with integrated computing, wireless communication modules, and separate tracking sensors, allowing independent optimization of each component while maintaining overall system functionality
2Ease of operation
If HMD systems are made self-contained with integrated computing components, then user mobility and freedom are improved, but device weight and complexity increase
Solution Approach 1:
The integrated processor and computing components serve multiple functions simultaneously - driving VR/AR rendering, processing sensor data, managing wireless communications, and coordinating tracking systems - thereby reducing the need for separate dedicated components and simplifying the overall system architecture
Solution Approach 2:
The patent combines previously separate components (display system, computing unit, battery, sensors) into a single integrated HMD headset, reducing the number of external connections and interfaces needed while maintaining full functionality
3Adaptability or versatility
If depth sensing technology and spatial mapping are implemented, then interaction capability with the environment is improved, but processing requirements and energy consumption increase
Solution Approach 1:
The depth sensing and spatial mapping operations are performed periodically at optimized intervals rather than continuously, allowing the system to capture environmental data at sufficient rates for interaction while reducing peak processing loads and energy consumption between mapping updates
Solution Approach 2:
The patent replaces complex mechanical interaction systems with optical and electromagnetic sensing methods (depth sensors, cameras, RFID readers) that detect and map the environment, enabling natural hand-tracking and gesture-based interactions without physical controllers or mechanical interfaces
