Image Data Transformation for User Position Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices face challenges in providing accurate depiction of text and images due to distortion when the user's position changes relative to the display, leading to unsatisfactory user experiences.
Innovation Solution
Incorporating a sensor and controller in computing devices to detect the user's position and apply image data transformation using perspective transformations, ensuring the image appears undistorted from the user's new position, thereby reducing visual distortions such as trapezoidal squares and lopsided ellipses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is viewed from a position other than the default position, then the user can view the display from different angles and positions, but the image data appears distorted (e.g., squares appear as trapezoids, circles as lopsided ellipses)
Solution Approach 1:
The system performs preliminary action by detecting the user's position relative to the display before the viewing occurs, and pre-transforms the image data according to the detected position. This ensures that when the user views the display from any position, the image has already been adjusted to appear undistorted from that specific angle, eliminating the need for real-time adjustment during viewing.
Solution Approach 2:
The system applies parameter changes by modifying the image data parameters (such as perspective transformation parameters, distortion correction factors) based on the detected user position. The controller adjusts these parameters dynamically to compensate for the viewing angle, ensuring that geometric shapes maintain their intended form regardless of the user's position relative to the display.
2Manufacturing precision
If image data is transformed based on user position, then distortion is reduced and image accuracy is improved, but the device complexity increases due to additional sensors and controllers
Solution Approach 1:
The system implements self-service by using the display device's own resources (existing processors, memory, and integrated sensors) to perform the image transformation function. Rather than requiring completely external systems, the display device autonomously detects user position and transforms image data using its built-in capabilities, minimizing the need for additional external components and reducing overall system complexity.

AI summary
A user position can be detected or determined using a sensor. A transformation can be applied to the image data based on the user position. The transformed image data can be displayed on a display.
