Eye Tracking Display Alignment for Viewing Angle Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic display solutions require users to physically adjust their position or the display to view information at an optimal angle, which can be inconvenient and inefficient.
Innovation Solution
An apparatus and method for display alignment based on eye tracking, using a processor, display module, user module, and alignment module to move graphical objects on a display screen to reduce the viewing angle between the object and the user's eyes, potentially incorporating facial recognition and wide-angle cameras to determine the user's location and gaze direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If graphical objects are displayed at a fixed location on the display screen, then the display structure is simple and stable, but the user must physically move the display or adjust their position to view at an optimal angle, reducing ease of operation
Solution Approach 1:
The display system automatically tracks the user's eye position and repositions graphical objects without requiring manual intervention. The eye tracking module continuously monitors user gaze, and the alignment module autonomously adjusts object positions to maintain optimal viewing angles, making the system self-adjusting rather than requiring user action
Solution Approach 2:
The display system transitions from static fixed-position graphical objects to dynamic repositionable objects. The alignment module continuously adjusts the positions of graphical objects based on real-time eye tracking data, making the display adaptive and flexible rather than rigid and fixed
2Productivity
If the user must physically move the display to achieve optimal viewing angle, then the display structure remains simple, but this requires additional physical effort and time, reducing productivity
Solution Approach 1:
The system replaces the mechanical action of physically moving the display or user body with an automated digital adjustment system. Eye tracking cameras detect gaze direction, and software algorithms automatically reposition graphical objects on the screen, substituting physical mechanical adjustment with optical detection and digital rendering
3Loss of information
If multiple graphical objects are displayed on the screen, then information density increases, but it becomes difficult for the user to locate and focus on specific objects, increasing the time to find information
Solution Approach 1:
The system proactively positions graphical objects in the user's field of view before the user needs to access them. By continuously monitoring eye position and predicting viewing intent, the alignment module pre-arranges objects in optimal positions, so when the user looks at a particular area, the relevant information is already positioned for immediate viewing
Solution Approach 2:
The display system provides different positioning strategies for different regions of the display screen based on user gaze. When the user looks at a specific area, objects in or near that region are prioritized and positioned optimally, while other objects maintain their positions, creating locally optimized viewing experiences rather than uniform global positioning
Data Source
AI summary
For display alignment based on eye tracking, a method is disclosed that includes displaying, by use of a processor, a graphical object on a display screen, detecting an aspect of a user relative to the display screen, and moving the graphical object to reduce a viewing angle between the graphical object and the aspect of a user.
