Customized Facial Interfacing Structure for VR Headsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted display systems for virtual and augmented reality are often uncomfortable due to poor fit, weight distribution, and clamping forces, leading to user discomfort and reduced usage time, as they fail to accommodate individual facial features effectively.
Innovation Solution
A method and system for customizing a head-mounted display's facial interfacing structure by collecting facial data to determine optimal dimensions, using machine learning to correlate facial features with interface design, and manufacturing a tailored structure that minimizes light leak and discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a standardized head-mounted display interface is used, then manufacturing cost and device complexity are reduced, but comfort and fit quality deteriorate due to inability to accommodate individual facial features
Solution Approach 1:
The system transitions from static standardized interfaces to dynamic customized interfaces by capturing facial images and generating personalized interfacing structure dimensions through machine learning algorithms, allowing the display interface to adapt to individual facial features while maintaining manufacturing efficiency
Solution Approach 2:
The patent changes the dimensional parameters of the facial interfacing structure based on extracted facial features (such as face width, height, and contour characteristics), optimizing the fit for each user by adjusting key geometric parameters rather than using fixed standardized sizes
2Manufacturing precision
If facial image data collection and machine learning processing are implemented, then customization precision and comfort are improved, but device complexity and processing time increase
Solution Approach 1:
The system enables self-service customization by allowing users to capture their own facial images using a mobile device camera and automatically generating customized interfacing structure dimensions through embedded machine learning models, eliminating the need for manual measurement or complex fitting procedures
Solution Approach 2:
The patent replaces traditional mechanical measurement systems (physical rulers, manual fitting) with optical image capture and computational machine learning algorithms, substituting physical measurement processes with digital image processing and automated dimension calculation
3Illumination intensity
If the display is positioned in close proximity to the user's eyes, then visual immersion and field of view are improved, but light leak and ambient light interference worsen
Solution Approach 1:
The patent applies different properties to different regions of the interfacing structure, with light-blocking material specifically applied to peripheral regions that contact the user's face, while maintaining transparency or openness in the central viewing area, thus blocking ambient light without interfering with the visual field
Data Source
AI summary
A system and method to collect collecting data for customizing a facial interfacing structure for a head-mounted display interface for virtual reality or augmented reality systems. Facial image data is correlated to a user such as by scanning the face of the user. Facial feature data related to the facial interfacing structure is determined from the facial image data. Dimensions of the facial interfacing structure are determined from the facial feature data. A design of a customized facial interfacing structure including the determined dimensions is stored to produce the customized facial interfacing structure.
