Camera-Based Display Posture Control With Sinusoidal Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require manual adjustment of height and tilt angle, which is inconvenient and cumbersome for users as their posture changes.
Innovation Solution
A display device with a signal input unit, a display unit equipped with a camera, a supporter, 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 from camera images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of display unit posture is used, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The display device automatically adjusts its own posture based on user posture detection through the camera and AI model, eliminating the need for manual operation. The system serves itself by detecting user position and autonomously controlling the posture adjustment driving unit to optimize display angle and height.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated system combining camera-based user posture detection, AI model processing, and electronic control of the posture adjustment driving unit. This substitutes human operation with an integrated sensor-processing-actuation system.
2Ease of operation
If automatic posture adjustment using AI model is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The controller integrates multiple functions including camera signal processing, AI model execution for posture inference, and control of the posture adjustment driving unit. This multi-functional integration automates the entire posture adjustment process from detection to execution, improving ease of operation despite increased complexity.
3Adaptability or versatility
If frequent posture adjustments are made, then adaptability is improved, but loss of time increases
Solution Approach 1:
The system continuously monitors user posture through the camera and uses AI model inference to detect posture changes. When a change is detected, the controller automatically adjusts the display unit posture accordingly, creating a closed-loop feedback system that adapts to user needs in real-time without requiring manual intervention.

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 camera to capture a first image of a viewer viewing the display unit, calculate a first viewer posture inferred by an artificial intelligence model from the first image captured by the camera, control the posture adjustment driving unit to adjust the posture of the display unit to correspond to a feature point of the viewer based on the calculated first viewer posture, and control the posture adjustment driving unit to adjust the posture of the display unit to have a height fluctuation of a sinusoidal curve trajectory continuous within a vertical top-bottom movement range of the display unit based on the calculated first viewer posture.
