Automatic Display Screen Adjustment via Eye Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display screen adjustment methods are manual and time-consuming, affecting user experience, especially for those with disabilities who cannot easily adjust the screen, leading to suboptimal viewing angles and positions.
Innovation Solution
A method and apparatus that acquire visual angle and fixation point information of a user relative to the display screen, determining a reference point position, and automatically adjust the screen's angle and position according to predetermined rules, eliminating the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual screen adjustment is used, then the user can adjust the screen position and angle, but it wastes time and affects viewing experience when not properly adjusted
Solution Approach 1:
The system uses eye tracking technology to automatically detect user gaze position and autonomously adjusts the display screen's position and angle without requiring manual user input. The controller receives gaze position information from the eye tracker and automatically controls the screen adjustment mechanism to optimize viewing angle and position based on where the user is looking.
Solution Approach 2:
The patent replaces the manual mechanical adjustment system with an automated system combining eye tracking (optical detection) and automated screen positioning. The eye tracker detects gaze position through optical means, and the controller translates this into automated mechanical screen adjustment, eliminating the need for manual mechanical operation.
2Ease of operation
If manual screen adjustment is used, then the user can adjust the screen, but users with disabilities who cannot move hands easily are unable to adjust the screen
Solution Approach 1:
The system performs self-adjustment by automatically detecting user gaze through eye tracking and autonomously positioning the display screen. This eliminates the need for manual hand operations, making the system accessible to users with mobility disabilities who cannot manually adjust the screen.
Solution Approach 2:
The eye tracker serves as an intermediary device that translates the user's natural gaze into screen adjustment commands. This intermediary mechanism allows users with disabilities to control screen position indirectly through eye movements rather than requiring direct manual manipulation of adjustment mechanisms.
3Extent of automation
If automatic eye tracking adjustment is implemented, then manual adjustment time is eliminated and accessibility is improved, but the device complexity increases
Solution Approach 1:
The eye tracker and screen adjustment mechanism are integrated into a unified system where a single eye tracking device controls multiple screen parameters (position and angle). This multi-functional integration reduces the need for separate control mechanisms for each adjustment parameter, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The controller acts as an intermediary that processes eye tracking data and translates it into appropriate screen adjustment commands. This centralized control architecture simplifies the system structure by using a single mediation point rather than requiring separate control systems for each screen parameter adjustment.

AI summary
The present disclosure provides a display screen adjusting method, a display screen adjusting apparatus and a display device. The method comprises the steps of: acquiring visual angle information and fixation point position information of a user relative to a display screen; determining a reference point position to which the display screen needs to be adjusted according to the fixation point position information; and adjusting the angle and position of the display screen according to the visual angle information, the reference point position and the current position of the display screen in light of a predetermined rule. The display screen adjusting method, the display screen adjusting apparatus and the display device can automatically adjust the angle and position of the display screen simultaneously without manual operation, thereby improving the user's viewing experience.
