Gaze-Tracked Laptop Display Height and Rotation Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clamshell devices, such as laptops, are ergonomically flawed due to a fixed display height relative to the keyboard, leading to posture and ergonomic issues, and existing solutions either only adjust the display height or require manual user intervention, failing to address the ergonomic positioning between the user's eyes and the display plane.
Innovation Solution
An electronic device with a display adjustment system that automatically adjusts the display height and orientation based on user gaze data, using cameras, IR sensors, and machine learning to ensure ergonomic positioning without manual intervention, incorporating a motor, worm gear, and display support for vertical adjustment and a rotation mechanism for additional positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display height is fixed relative to the keyboard in clamshell devices, then the device structure is simple and compact, but ergonomic positioning between user eyes and display is compromised
Solution Approach 1:
The display height is changed from a fixed state to a dynamically adjustable state. The motor-driven mechanism allows the display to move vertically along the hinge axis, enabling real-time adaptation to different user needs while maintaining a relatively compact form factor when closed.
Solution Approach 2:
The system uses eye-tracking cameras and sensors to automatically detect user gaze position and autonomously adjusts the display height without requiring manual user intervention. This self-service approach resolves the contradiction by eliminating the need for complex manual adjustment mechanisms while achieving ergonomic positioning.
2Ease of operation
If manual user intervention is required to adjust display height, then the device complexity is reduced, but user convenience and ergonomics are degraded
Solution Approach 1:
The system incorporates cameras and sensors that continuously monitor user eye position and gaze direction. This feedback is processed by the controller which automatically adjusts the display height to maintain optimal ergonomic positioning, eliminating the need for manual intervention while enhancing user convenience.
Solution Approach 2:
Manual mechanical adjustment is replaced with an automated electromechanical system. The motor-driven mechanism, controlled by electronic sensors and processing units, substitutes for simple manual cranks or sliders, providing automatic ergonomic adjustment despite increased system complexity.
3Weight of moving object
If the display is made portable and compact, then device portability is improved, but automatic ergonomic adjustment capabilities are limited
Solution Approach 1:
The display adjustment system is segmented into modular components: a compact motor unit, a hinge-integrated drive mechanism, and distributed sensors. This segmentation allows the automatic adjustment system to be incorporated into the portable device without excessive weight increase, as each component is optimized for minimal mass while maintaining functionality.
Data Source
AI summary
Particular embodiments described herein provide for an electronic device that can be configured to receive data related to a gaze of a user, determine that a display should be adjusted based on the received data related to the gaze of the user, and activate a motor, where the motor causes the height of the display to be adjusted. In an example, the electronic device can also determine that the display should be rotated based on the received data related to the gaze of the user and rotate the display.
