AI-Guided Display Posture Adjustment for Upright Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require manual adjustment of the display unit's height and tilt angle, which is inconvenient and cumbersome when a user's posture changes.
Innovation Solution
A display device equipped with a camera, a signal input unit, and a posture adjustment driving unit, controlled by a controller using artificial intelligence to automatically adjust the display unit's posture based on user posture inference, including 2D and 3D landmark analysis and user preference settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of display unit height and tilt angle is used, then device complexity is reduced, but ease of operation deteriorates when user posture changes
Solution Approach 1:
The display device automatically adjusts its own posture (height and tilt angle) by detecting user posture through the camera and AI model, eliminating the need for manual user adjustment. The system serves itself by autonomously optimizing the display unit's position based on real-time user posture analysis.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated system comprising a camera, AI model, and posture adjustment driving unit. The mechanical adjustment mechanism is controlled automatically through electronic signals generated by the AI-based posture detection system, substituting human mechanical interaction with an automated electromechanical system.
2Adaptability or versatility
If automatic posture adjustment using AI model and camera is implemented, then ease of operation improves, but device complexity increases
Solution Approach 1:
The camera serves multiple functions: capturing user images for posture detection, calculating spaced distances through feature point analysis, and providing input data for the AI model. The AI model itself performs multiple tasks including inferring user posture, calculating distances, and determining optimal display unit positioning, demonstrating multi-functionality that justifies the added complexity.
Solution Approach 2:
The AI model acts as an intermediary between the camera's raw image data and the posture adjustment driving unit's control signals. It processes images to extract posture information and translates this into actionable adjustment commands, serving as a intelligent mediator that bridges perception and action in the system.
3Measurement precision
If spaced distance calculation based on feature point pixel distance is used, then measurement precision improves, but device complexity increases
Solution Approach 1:
The system creates a digital copy of the user's facial features through 2D landmark detection from camera images. By analyzing pixel distances between feature points in this digital representation, the system calculates real-world spaced distances without requiring direct physical measurement, achieving precise measurement through digital modeling.

AI summary
A display device including a display unit having a display panel and a camera; a posture adjustment driving unit configured to adjust a posture of the display unit; and a controller configured to control the posture adjustment unit to adjust the posture of the display unit to be raised to a top end of a vertical movement range of the display unit and to tilt downwards or to be lowered to a bottom end of the vertical movement range of the display unit and to tilt upwards, control the camera to detect if a viewer is viewing the display unit when the display unit is raised to the top end or bottom end of the vertical movement range, determine a current posture of the viewer when the viewer is detected, and control the posture adjustment unit to adjust the posture of the display unit so the current posture of the viewer is changed into an upright posture with eyes of the viewer being centrally located within an area of the display unit.
