Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gaming systems with head-mounted displays (HMDs) lack the ability to automatically adjust optical settings for individual users' vision, leading to suboptimal clarity and requiring manual adjustments, which can be inconvenient and may not accommodate users' optical characteristics.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual optical adjustments are required for HMD, then device complexity is reduced, but image clarity and adaptability to user vision deteriorate
Solution Approach 1:
The system automatically determines user optical characteristics through vision tests and biometric identification, then self-adjusts the HMD optical settings without requiring manual user intervention. The vision test module assesses user visual acuity and the optical adjustment module automatically configures the display parameters accordingly.
Solution Approach 2:
The system changes optical parameters such as focal length, field of view, and display resolution based on individual user vision characteristics. By dynamically adjusting these parameters according to user-specific data from vision tests and biometric identification, the system optimizes image clarity for each user.
2Adaptability or versatility
If optical settings are customized per user, then adaptability to user vision improves, but ease of operation deteriorates due to manual adjustment requirements
Solution Approach 1:
The system incorporates vision tests that provide feedback on user visual characteristics and biometric identification that automatically triggers optical setting adjustments. This closed-loop feedback mechanism ensures that optical settings are continuously optimized based on user-specific data without requiring manual input.
Solution Approach 2:
The HMD system performs self-configuration by automatically conducting vision assessments and adjusting optical parameters based on user identity and visual characteristics. This eliminates the need for users to manually adjust settings while maintaining personalized optimization.
3Ease of operation
If automatic optical adjustment is implemented, then ease of operation improves, but device complexity increases
Solution Approach 1:
The system integrates multiple functions including vision testing, biometric identification, optical parameter calculation, and automatic adjustment into a unified HMD platform. This multi-functional approach consolidates complexity into a single system rather than requiring separate devices for each function.
Solution Approach 2:
The system replaces manual mechanical adjustment mechanisms with automated software-based control. By using computational algorithms to determine optimal optical settings based on vision test data and biometric information, the system eliminates physical adjustment mechanisms while maintaining precision.
4Measurement precision
If vision tests and biometric identification are used, then measurement precision of user optical characteristics improves, but device complexity and difficulty of detection increase
Solution Approach 1:
The system performs vision tests and optical characteristic assessments during initial setup or calibration periods, storing the results for later use. This preliminary measurement approach avoids repeated complex measurements during normal operation, reducing real-time detection difficulty while maintaining precision.
Solution Approach 2:
The system creates a digital profile or copy of user optical characteristics based on vision test results and biometric data. This stored profile serves as a reference for automatic optical adjustments without requiring repeated complex measurements, simplifying subsequent detection and measurement operations.

AI summary
Systems and methods for operating a screen of a head mounted display includes executing a program. The execution of the program causes rendering of images on the screen of the HMD. The screen renders the images using a first optical setting. A first image is presented on the screen. The first image has a first size and is presented at a distance. Input is received identifying a clarity level for the first image. A second image is presented on the screen. The second image has a second size and the distance. Input is received identifying the clarity level for the second image. Based on the clarity level received for the first and the second images, the first optical setting for the screen is changed to a second optical setting. The optical setting adjustments may compensate for deficiencies in a user's vision. A biometric identify may be used to identify a user. The optical setting adjustments may be based on a stored user profile or a user's optical prescription.
