Solution Overview
Problem
Current virtual reality (VR) systems are not compatible with glasses and require manual adjustments for users with myopia, leading to discomfort and reduced user experience due to mechanical adjustments that often result in improper correction.
Innovation Solution
A VR headset system with a built-in vision correction module that includes a myopia detection unit and a lens adjustment unit, using infrared signals to detect the degree of myopia and automatically adjust the lenses for precise vision correction, allowing for separate adjustments for each eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual mechanical adjustments are used to correct myopia in VR systems, then the system can be adjusted for different users, but the adjustment precision is poor and causes discomfort
Solution Approach 1:
The VR system automatically detects the user's myopia degree through infrared optical axis detection and self-adjusts the lens parameters without requiring manual intervention. The system performs optometry detection and lens adjustment autonomously, eliminating the need for users to manually turn mechanical gears or select adjustment lenses.
Solution Approach 2:
The patent replaces manual mechanical adjustment mechanisms with an automated optical detection and control system. Instead of using mechanical gears and manual lens selection, the system uses infrared light detection, computer vision algorithms, and automated lens parameter adjustment to achieve precise myopia correction.
2Productivity
If manual adjustment mechanisms are provided, then users can attempt to correct their vision, but the process is time-consuming and reduces productivity
Solution Approach 1:
The system performs optometry detection and lens parameter adjustment automatically during the initial setup phase or before each VR session. By pre-configuring the correct lens parameters based on detected myopia degree, the system eliminates the need for time-consuming manual adjustments during actual VR usage.
Solution Approach 2:
The automated detection and adjustment system performs vision correction setup without requiring user intervention or time investment. The system independently completes the entire optometry and lens configuration process, significantly reducing setup time compared to manual adjustment methods.
3Adaptability or versatility
If mechanical adjustment mechanisms are used, then some vision correction is possible, but the system lacks adaptability for different vision impairments
Solution Approach 1:
The VR system incorporates a universal optometry detection and adjustment mechanism that can handle multiple types of vision impairments including myopia, hyperopia, and astigmatism. The infrared detection system and automated lens adjustment capability provide a unified solution that adapts to various vision conditions without requiring separate adjustment mechanisms for each type of impairment.
4Ease of operation
If users wear glasses with VR headsets, then they can maintain their vision correction, but the glasses are not compatible and cause discomfort
Solution Approach 1:
The patent introduces an intermediary optical system within the VR headset that provides vision correction without requiring external glasses. The built-in adjustable lens acts as an intermediary optical element that compensates for myopia while maintaining compatibility with the VR headset structure, eliminating the need to wear glasses simultaneously and avoiding associated discomfort.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides clear and focused VR experiences for users with myopia by automatically adjusting the lenses, enhancing comfort and reducing eye strain, while being compatible with various vision impairments such as hyperopia and presbyopia.
Implementation Method 1
A focus unit transmits an infrared (IR) signal to a user's eye when the VR system is worn by the user and adjusts the adjustable lens in response to reflections of the IR signal from the user's eyes.
Implementation Method 2
A focus unit transmits an infrared (IR) signal to a user's eye when the VR system is worn by the user and adjusts the adjustable lens in response to reflections of the IR signal from the user's eyes.
Implementation Method 3
an adjustable lens; wherein the focus unit is to adjust a position of the adjustable lens
Data Source
AI summary
A virtual reality headset system includes a vision correction module. The vision correction system can detect a degree of myopia or other visual ailment of a user of the VR system, and then adjust a vision correction lens to adjust for user myopia. An implementation of the vision correction module can adjust right and left lenses separately.
