Transparent Display Jitter Reduction via Coordinate Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent displays that show dynamic information behind the panel can cause discomfort due to movement or jitter of recognition information when objects move, affecting user viewing comfort.
Innovation Solution
An information display system comprising a display screen, an image-capture device, and a processing device that captures a picture sequence, recognizes dynamic objects, generates recognition frames, tracks these frames, and compensates display coordinates to reduce jitter and improve user comfort by stabilizing the recognition information on the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transparent display shows dynamic information behind the panel, then information display function is improved, but recognition information jitters when objects move, affecting user viewing comfort
Solution Approach 1:
The system performs preliminary tracking of the dynamic object's position across multiple frames before displaying the recognition information. By pre-calculating and storing the trajectory data of the object, the system can compensate for position changes in advance, ensuring stable display positioning even when the object moves during capture.
Solution Approach 2:
The system continuously monitors the position of the dynamic object through image capture and uses this feedback to adjust the display coordinate of the recognition information. The processing device calculates the displacement between consecutive frames and compensates accordingly, creating a closed-loop control system that maintains stable information display despite object movement.
2Measurement precision
If recognition information is displayed at the object's current position, then information accuracy is improved, but visual discontinuity and jitter occur when object moves or jitters
Solution Approach 1:
The system pre-processes the image sequence to track the object's trajectory before final display. By analyzing multiple consecutive frames and pre-calculating the object's movement path, the system establishes a stable reference frame that prevents jitter in the displayed recognition information, even when the object is in motion during capture.
Solution Approach 2:
The system introduces an intermediary compensation mechanism between the object's actual position and the displayed recognition information. This intermediary layer processes the position data through trajectory prediction and coordinate transformation, acting as a buffer that decouples the direct relationship between object movement and display position, thereby eliminating visual discontinuity.

AI summary
An information display system and an information display method are provided. The information display system includes a display screen, an image-capture device, and a processing device. The image-capture device captures a picture sequence. The processing device is coupled to the display screen and the image-capture device. The processing device recognizes at least one dynamic object in the picture sequence and generates a recognition frame and a recognition information corresponding to the dynamic object. The processing device tracks a recognition frame of a plurality of first pictures in the picture sequence to obtain a tracking result. The processing device compensates a display coordinate of a recognition information of a second picture in the picture sequence according to the tracking result to obtain a compensated coordinate, and displays the recognition information on the display screen according to the compensated coordinate to reduce a jitter of the recognition information displayed on the display screen. The first pictures are prior to the second picture in terms of time sequence.
