Eye Gaze Plane Based Display Orientation Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display orientation technologies, such as those using gyroscopes and accelerometers, only adjust content at 90-degree increments and may invert content when the device is tilted away from the user, leading to suboptimal viewing experiences.
Innovation Solution
A system that determines the user's eye gaze plane and nose position to dynamically adjust content display orientation in real-time, ensuring alignment with the user's line of sight and body position, regardless of device orientation or position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If 90-degree increment adjustment based on device position is used, then device complexity is reduced, but viewing experience deteriorates when device is tilted away from user
Solution Approach 1:
The patent replaces the mechanical gyroscope-based orientation detection system with an optical tracking system using cameras to detect eye gaze and head position. This substitution allows for continuous orientation adjustment based on actual user viewing direction rather than device mechanical orientation, resolving the contradiction by maintaining simple device mechanics while achieving reliable viewing experience through optical sensing and software-based orientation correction
Solution Approach 2:
The patent changes the adjustment parameter from discrete 90-degree increments to continuous orientation values based on eye gaze direction and head position. By detecting the user's actual viewing angle and dynamically adjusting content orientation to match, the system maintains reliable viewing experience across all device tilts while keeping the adjustment mechanism computationally simple rather than mechanically complex
2Ease of operation
If content orientation is based on device position, then ease of operation is improved, but adaptability to user orientation deteriorates
Solution Approach 1:
The patent implements a feedback loop where cameras continuously track the user's eye gaze and head position, and the system automatically adjusts content orientation based on this real-time data. This feedback mechanism enables the display to adapt to user orientation naturally without requiring manual operation, resolving the contradiction by making the system both easy to operate (automatic) and highly adaptable (responds to user position)
3Productivity
If automatic orientation adjustment is implemented, then productivity is improved, but measurement precision requirements increase
Solution Approach 1:
The patent introduces cameras as intermediary sensing devices that capture visual information about eye and head position. These cameras serve as mediators between the user's physical orientation and the digital content orientation, translating complex biological movements into adjustable display parameters. This intermediary approach improves productivity through automatic adjustment while managing measurement precision requirements through robust computer vision algorithms that can handle natural variations in user positioning

AI summary
A system for adjusting content display orientation on a screen is disclosed. The system may include a processor that may detect both eyes and a body part of a user that is proximal to one or more of the user's eyes. The system may then determine an eye gaze plane based on the positions of the first and second eyes of the user. The eye gaze plane may be determined by identifying a first line of sight extending from the first eye and a second line of sight extending from the second eye. Additionally, the eye gaze plane may bisect a center of the first eye and a center of the second eye of the user. Once the eye gaze plane is determined, the system may adjust the orientation of content displayed on a display device based on the eye gaze plane and on the position of the body part.
