Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with vision abnormalities face difficulties in viewing digital content without their corrective eyewear, leading to blurry images and increased eye strain, especially in daily tasks involving digital displays.
Innovation Solution
An electronic device method and apparatus that applies pre-programmed compensation algorithms to digital content to enhance viewing quality for users not wearing corrective lenses, using user input signals or empirical identification to select the appropriate algorithm based on common settings for corrective eyewear, and applying algebraic transforms like the Lensmaker's Equation to correct focal issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users view digital content without corrective eyewear, then device portability and convenience are improved, but image clarity and viewing quality deteriorate
Solution Approach 1:
The patent applies optical compensation algorithms that modify the display parameters (focal length, curvature, magnification) to counteract the user's vision abnormalities. By dynamically adjusting these display parameters based on the user's prescription data, the system enables clear viewing without physical corrective lenses, resolving the contradiction between convenience and image clarity.
Solution Approach 2:
The patent replaces the mechanical optical correction system (physical glasses or contact lenses) with a computational optical compensation system. Instead of using external optical elements to correct vision, the system uses software-based algorithms to pre-compensate the displayed content, substituting a mechanical solution with a computational one that eliminates the need for wearable corrective devices.
2Manufacturing precision
If corrective eyewear is worn to maintain image clarity, then viewing quality is improved, but device portability and ease of use deteriorate
Solution Approach 1:
The patent extracts the optical correction function from the physical eyewear and transfers it to the display system. By separating the correction function from the wearable component and embedding it in the display's software, the system eliminates the need to carry or wear corrective lenses while maintaining image clarity, thus resolving the contradiction between viewing quality and convenience.
Solution Approach 2:
The patent makes the display system multi-functional by integrating both content display and optical correction capabilities into a single device. The display not only shows content but also actively compensates for vision abnormalities, eliminating the need for separate corrective eyewear and improving overall convenience while maintaining image clarity.
3Adaptability or versatility
If multiple compensation algorithms are stored for different vision abnormalities, then adaptability to various users is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic algorithm selection mechanism that automatically matches the user's vision prescription to the appropriate compensation algorithm. Instead of manually selecting from multiple algorithms, the system dynamically identifies the user's needs and selects the optimal algorithm in real-time, reducing the perceived complexity while maintaining high adaptability to different vision conditions.
Solution Approach 2:
The patent enables the system to automatically manage the compensation algorithms by self-identifying the appropriate algorithm based on the user's prescription data. The system performs automatic matching and selection without requiring user intervention or complex manual configuration, thereby maintaining adaptability while simplifying the user experience and reducing operational complexity.

AI summary
The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory or a storage device) for compensation of viewing quality in display/imaging devices for users with common vision abnormalities. In case a user not wearing compensation lenses (such as prescription eye glasses or contact lenses) it can be possible to compensate for user's vision abnormalities by applying an identified pre-programmed/stored compensation algorithm, corresponding to one of a plurality of common settings for corrective eye glasses, to the original content/image (e.g., video, multi-media content, digital pictures and the like), for displaying the resulting content on the display/imaging device for viewing with an acceptable level of quality by the user without wearing the compensation lenses.
