Automatic Seat Positioning via Eye Tracking Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for positioning seats in vehicles, such as aircraft, are often tedious and prone to incorrect positioning, requiring manual adjustment by pilots to achieve an optimal viewing and control alignment.
Innovation Solution
A method utilizing two cameras positioned on either side of the seat to automatically adjust the seat along predefined axes, ensuring that the pilot's eyes are aligned with predefined zones for optimal positioning, with motors actuated based on image detection and processing to achieve precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment method is used, then device complexity is reduced, but positioning precision deteriorates and operation time increases
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated optical-mechanical system. Two cameras capture images of the user's eyes, and a processing unit automatically calculates and actuates motors to position the seat, substituting manual mechanical operation with automated image-processing and motor-driven positioning.
Solution Approach 2:
The system enables self-service positioning by automatically detecting the user's eye position through cameras and autonomously adjusting the seat to the optimal position without requiring manual intervention from the user.
2Productivity
If manual adjustment method is used, then device complexity is reduced, but productivity deteriorates due to increased operation time
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated optical-mechanical system. Two cameras capture images of the user's eyes, and a processing unit automatically calculates and actuates motors to position the seat, substituting manual mechanical operation with automated image-processing and motor-driven positioning.
Solution Approach 2:
The system enables continuous automated positioning by capturing images, processing data, and actuating motors in a seamless workflow, eliminating the intermittent manual adjustments and maximizing positioning efficiency.
3Measurement precision
If automatic positioning with cameras and motors is implemented, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces the manual mechanical adjustment system with an automated optical-mechanical system. Two cameras capture images of the user's eyes, and a processing unit automatically calculates and actuates motors to position the seat, substituting manual mechanical operation with automated image-processing and motor-driven positioning.
Solution Approach 2:
The patent introduces cameras and a processing unit as intermediary elements between the user and the seat adjustment mechanism. These intermediaries capture eye position data, process it to determine optimal positioning, and translate it into motor commands, thereby achieving precise positioning while maintaining system organization.

AI summary
A method of automatic positioning a seat in an apparatus comprising two cameras located on either side of the seat, each one in a position able to acquire images of a face of a user seated on the seat. The seat comprises at least one motor, each motor acting on a position of the seat along a predefined axis. The method comprises: for each camera: obtaining a position of a predefined image zone in which at least one eye of a user of the apparatus should be located; acquiring an image of a user seated on the seat; detecting at least one eye of the seated user in the image acquired; and obtaining a relative position between each eye detected and the predefined zone. By using each relative position obtained, at least one motor is actuated until each predefined zone contains at least one eye of the seated user.
